##### `checkConnLiveness`
```
Type: bool
Valid Values: true, false
Default: true
```
On supported platforms connections retrieved from the connection pool are checked for liveness before using them. If the check fails, the respective connection is marked as bad and the query retried with another connection.
`checkConnLiveness=false` disables this liveness check of connections.
##### `collation`
```
Type: string
Valid Values: <name>
Default: utf8_general_ci
Default: utf8mb4_general_ci
```
Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
The default collation (`utf8mb4_general_ci`) is supported from MySQL 5.5. You should use an older collation (e.g. `utf8_general_ci`) for older MySQL.
Collations for charset "ucs2", "utf16", "utf16le", and "utf32" can not be used ([ref](https://dev.mysql.com/doc/refman/5.7/en/charset-connection.html#charset-connection-impermissible-client-charset)).

`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side) or use `preferred` to use TLS only when advertised by the server. This is similar to `skip-verify`, but additionally allows a fallback to a connection which is not encrypted. Neither `skip-verify` nor `preferred` add any reliable security.

### `time.Time` support
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.

You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).

### Unicode support
Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default.
Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_general_ci` by default.
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support.
See http://dev.mysql.com/doc/refman/8.0/en/charset-unicode.html for more details on MySQL's Unicode support.
## Testing / Development
To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.

# SQL builder
[![GitCI.cn](https://gitci.cn/api/badges/go-xorm/builder/status.svg)](https://gitci.cn/go-xorm/builder) [![codecov](https://codecov.io/gh/go-xorm/builder/branch/master/graph/badge.svg)](https://codecov.io/gh/go-xorm/builder)
[![](https://goreportcard.com/badge/github.com/go-xorm/builder)](https://goreportcard.com/report/github.com/go-xorm/builder)
Package builder is a lightweight and fast SQL builder for Go and XORM.
Make sure you have installed Go 1.8+ and then:
go get github.com/go-xorm/builder
# Insert
```Go
sql, args, err := builder.Insert(Eq{"c": 1, "d": 2}).Into("table1").ToSQL()
// INSERT INTO table1 SELECT * FROM table2
sql, err := builder.Insert().Into("table1").Select().From("table2").ToBoundSQL()
// INSERT INTO table1 (a, b) SELECT b, c FROM table2
sql, err = builder.Insert("a, b").Into("table1").Select("b, c").From("table2").ToBoundSQL()
```
# Select
```Go
// Simple Query
sql, args, err := Select("c, d").From("table1").Where(Eq{"a": 1}).ToSQL()
// With join
sql, args, err = Select("c, d").From("table1").LeftJoin("table2", Eq{"table1.id": 1}.And(Lt{"table2.id": 3})).
RightJoin("table3", "table2.id = table3.tid").Where(Eq{"a": 1}).ToSQL()
// From sub query
sql, args, err := Select("sub.id").From(Select("c").From("table1").Where(Eq{"a": 1}), "sub").Where(Eq{"b": 1}).ToSQL()
// From union query
sql, args, err = Select("sub.id").From(
Select("id").From("table1").Where(Eq{"a": 1}).Union("all", Select("id").From("table1").Where(Eq{"a": 2})),"sub").
Where(Eq{"b": 1}).ToSQL()
// With order by
sql, args, err = Select("a", "b", "c").From("table1").Where(Eq{"f1": "v1", "f2": "v2"}).
OrderBy("a ASC").ToSQL()
// With limit.
// Be careful! You should set up specific dialect for builder before performing a query with LIMIT
sql, args, err = Dialect(MYSQL).Select("a", "b", "c").From("table1").OrderBy("a ASC").
Limit(5, 10).ToSQL()
```
# Update
```Go
sql, args, err := Update(Eq{"a": 2}).From("table1").Where(Eq{"a": 1}).ToSQL()
```
# Delete
```Go
sql, args, err := Delete(Eq{"a": 1}).From("table1").ToSQL()
```
# Union
```Go
sql, args, err := Select("*").From("a").Where(Eq{"status": "1"}).
Union("all", Select("*").From("a").Where(Eq{"status": "2"})).
Union("distinct", Select("*").From("a").Where(Eq{"status": "3"})).
Union("", Select("*").From("a").Where(Eq{"status": "4"})).
ToSQL()
```
# Conditions
* `Eq` is a redefine of a map, you can give one or more conditions to `Eq`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Eq{"a":1})
// a=? [1]
sql, args, _ := ToSQL(Eq{"b":"c"}.And(Eq{"c": 0}))
// b=? AND c=? ["c", 0]
sql, args, _ := ToSQL(Eq{"b":"c", "c":0})
// b=? AND c=? ["c", 0]
sql, args, _ := ToSQL(Eq{"b":"c"}.Or(Eq{"b":"d"}))
// b=? OR b=? ["c", "d"]
sql, args, _ := ToSQL(Eq{"b": []string{"c", "d"}})
// b IN (?,?) ["c", "d"]
sql, args, _ := ToSQL(Eq{"b": 1, "c":[]int{2, 3}})
// b=? AND c IN (?,?) [1, 2, 3]
```
* `Neq` is the same to `Eq`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Neq{"a":1})
// a<>? [1]
sql, args, _ := ToSQL(Neq{"b":"c"}.And(Neq{"c": 0}))
// b<>? AND c<>? ["c", 0]
sql, args, _ := ToSQL(Neq{"b":"c", "c":0})
// b<>? AND c<>? ["c", 0]
sql, args, _ := ToSQL(Neq{"b":"c"}.Or(Neq{"b":"d"}))
// b<>? OR b<>? ["c", "d"]
sql, args, _ := ToSQL(Neq{"b": []string{"c", "d"}})
// b NOT IN (?,?) ["c", "d"]
sql, args, _ := ToSQL(Neq{"b": 1, "c":[]int{2, 3}})
// b<>? AND c NOT IN (?,?) [1, 2, 3]
```
* `Gt`, `Gte`, `Lt`, `Lte`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Gt{"a", 1}.And(Gte{"b", 2}))
// a>? AND b>=? [1, 2]
sql, args, _ := ToSQL(Lt{"a", 1}.Or(Lte{"b", 2}))
// a<? OR b<=? [1, 2]
```
* `Like`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Like{"a", "c"})
// a LIKE ? [%c%]
```
* `Expr` you can customerize your sql with `Expr`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Expr("a = ? ", 1))
// a = ? [1]
sql, args, _ := ToSQL(Eq{"a": Expr("select id from table where c = ?", 1)})
// a=(select id from table where c = ?) [1]
```
* `In` and `NotIn`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(In("a", 1, 2, 3))
// a IN (?,?,?) [1,2,3]
sql, args, _ := ToSQL(In("a", []int{1, 2, 3}))
// a IN (?,?,?) [1,2,3]
sql, args, _ := ToSQL(In("a", Expr("select id from b where c = ?", 1))))
// a IN (select id from b where c = ?) [1]
```
* `IsNull` and `NotNull`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(IsNull{"a"})
// a IS NULL []
sql, args, _ := ToSQL(NotNull{"b"})
// b IS NOT NULL []
```
* `And(conds ...Cond)`, And can connect one or more condtions via And
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(And(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
// a=? AND b LIKE ? AND d<>? [1, %c%, 2]
```
* `Or(conds ...Cond)`, Or can connect one or more conditions via Or
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Or(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
// a=? OR b LIKE ? OR d<>? [1, %c%, 2]
sql, args, _ := ToSQL(Or(Eq{"a":1}, And(Like{"b", "c"}, Neq{"d", 2})))
// a=? OR (b LIKE ? AND d<>?) [1, %c%, 2]
```
* `Between`
```Go
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Between{"a", 1, 2})
// a BETWEEN 1 AND 2
```
* Define yourself conditions
Since `Cond` is an interface.
```Go
type Cond interface {
WriteTo(Writer) error
And(...Cond) Cond
Or(...Cond) Cond
IsValid() bool
}
```
You can define yourself conditions and compose with other `Cond`.

/*
Package builder is a simple and powerful sql builder for Go.
Make sure you have installed Go 1.1+ and then:
go get github.com/go-xorm/builder
WARNNING: Currently, only query conditions are supported. Below is the supported conditions.
1. Eq is a redefine of a map, you can give one or more conditions to Eq
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Eq{"a":1})
// a=? [1]
sql, args, _ := ToSQL(Eq{"b":"c"}.And(Eq{"c": 0}))
// b=? AND c=? ["c", 0]
sql, args, _ := ToSQL(Eq{"b":"c", "c":0})
// b=? AND c=? ["c", 0]
sql, args, _ := ToSQL(Eq{"b":"c"}.Or(Eq{"b":"d"}))
// b=? OR b=? ["c", "d"]
sql, args, _ := ToSQL(Eq{"b": []string{"c", "d"}})
// b IN (?,?) ["c", "d"]
sql, args, _ := ToSQL(Eq{"b": 1, "c":[]int{2, 3}})
// b=? AND c IN (?,?) [1, 2, 3]
2. Neq is the same to Eq
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Neq{"a":1})
// a<>? [1]
sql, args, _ := ToSQL(Neq{"b":"c"}.And(Neq{"c": 0}))
// b<>? AND c<>? ["c", 0]
sql, args, _ := ToSQL(Neq{"b":"c", "c":0})
// b<>? AND c<>? ["c", 0]
sql, args, _ := ToSQL(Neq{"b":"c"}.Or(Neq{"b":"d"}))
// b<>? OR b<>? ["c", "d"]
sql, args, _ := ToSQL(Neq{"b": []string{"c", "d"}})
// b NOT IN (?,?) ["c", "d"]
sql, args, _ := ToSQL(Neq{"b": 1, "c":[]int{2, 3}})
// b<>? AND c NOT IN (?,?) [1, 2, 3]
3. Gt, Gte, Lt, Lte
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Gt{"a", 1}.And(Gte{"b", 2}))
// a>? AND b>=? [1, 2]
sql, args, _ := ToSQL(Lt{"a", 1}.Or(Lte{"b", 2}))
// a<? OR b<=? [1, 2]
4. Like
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Like{"a", "c"})
// a LIKE ? [%c%]
5. Expr you can customerize your sql with Expr
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Expr("a = ? ", 1))
// a = ? [1]
sql, args, _ := ToSQL(Eq{"a": Expr("select id from table where c = ?", 1)})
// a=(select id from table where c = ?) [1]
6. In and NotIn
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(In("a", 1, 2, 3))
// a IN (?,?,?) [1,2,3]
sql, args, _ := ToSQL(In("a", []int{1, 2, 3}))
// a IN (?,?,?) [1,2,3]
sql, args, _ := ToSQL(In("a", Expr("select id from b where c = ?", 1))))
// a IN (select id from b where c = ?) [1]
7. IsNull and NotNull
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(IsNull{"a"})
// a IS NULL []
sql, args, _ := ToSQL(NotNull{"b"})
// b IS NOT NULL []
8. And(conds ...Cond), And can connect one or more condtions via AND
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(And(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
// a=? AND b LIKE ? AND d<>? [1, %c%, 2]
9. Or(conds ...Cond), Or can connect one or more conditions via Or
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Or(Eq{"a":1}, Like{"b", "c"}, Neq{"d", 2}))
// a=? OR b LIKE ? OR d<>? [1, %c%, 2]
sql, args, _ := ToSQL(Or(Eq{"a":1}, And(Like{"b", "c"}, Neq{"d", 2})))
// a=? OR (b LIKE ? AND d<>?) [1, %c%, 2]
10. Between
import . "github.com/go-xorm/builder"
sql, args, _ := ToSQL(Between("a", 1, 2))
// a BETWEEN 1 AND 2
11. define yourself conditions
Since Cond is a interface, you can define yourself conditions and compare with them

Core is a lightweight wrapper of sql.DB.
[![CircleCI](https://circleci.com/gh/go-xorm/core/tree/master.svg?style=svg)](https://circleci.com/gh/go-xorm/core/tree/master)
# Open
```Go
db, _ := core.Open(db, connstr)
```
# SetMapper
```Go
db.SetMapper(SameMapper())
```
## Scan usage
### Scan
```Go
rows, _ := db.Query()
for rows.Next() {
rows.Scan()
}
```
### ScanMap
```Go
rows, _ := db.Query()
for rows.Next() {
rows.ScanMap()
```
### ScanSlice
You can use `[]string`, `[][]byte`, `[]interface{}`, `[]*string`, `[]sql.NullString` to ScanSclice. Notice, slice's length should be equal or less than select columns.
```Go
rows, _ := db.Query()
cols, _ := rows.Columns()
for rows.Next() {
var s = make([]string, len(cols))
rows.ScanSlice(&s)
}
```
```Go
rows, _ := db.Query()
cols, _ := rows.Columns()
for rows.Next() {
var s = make([]*string, len(cols))
rows.ScanSlice(&s)
}
```
### ScanStruct
```Go
rows, _ := db.Query()

```
## Query usage
```Go
rows, err := db.Query("select * from table where name = ?", name)
user = User{
Name:"lunny",
}
rows, err := db.QueryStruct("select * from table where name = ?Name",
&user)
var user = map[string]interface{}{
"name": "lunny",
}
rows, err = db.QueryMap("select * from table where name = ?name",
&user)
```
## QueryRow usage
```Go
row := db.QueryRow("select * from table where name = ?", name)
user = User{
Name:"lunny",
}
row := db.QueryRowStruct("select * from table where name = ?Name",
&user)
var user = map[string]interface{}{
"name": "lunny",
}
row = db.QueryRowMap("select * from table where name = ?name",
&user)
```
## Exec usage
```Go
db.Exec("insert into user (`name`, title, age, alias, nick_name,created) values (?,?,?,?,?,?)", name, title, age, alias...)
user = User{
Name:"lunny",
Title:"test",
Age: 18,
}

var user = map[string]interface{}{
"Name": "lunny",

"Age": 18,
}
result, err = db.ExecMap("insert into user (`name`, title, age, alias, nick_name,created) values (?Name,?Title,?Age,?Alias,?NickName,?Created)",

## Contributing to xorm
`xorm` has a backlog of [pull requests](https://help.github.com/articles/using-pull-requests), but contributions are still very
much welcome. You can help with patch review, submitting bug reports,
or adding new functionality. There is no formal style guide, but
please conform to the style of existing code and general Go formatting
conventions when submitting patches.
* [fork a repo](https://help.github.com/articles/fork-a-repo)
* [creating a pull request ](https://help.github.com/articles/creating-a-pull-request)
### Language
Since `xorm` is a world-wide open source project, please describe your issues or code changes in English as soon as possible.
### Sign your codes with comments
```
// !<you github id>! your comments
e.g.,
// !lunny! this is comments made by lunny
```
### Patch review
Help review existing open [pull requests](https://help.github.com/articles/using-pull-requests) by commenting on the code or
proposed functionality.
### Bug reports
We appreciate any bug reports, but especially ones with self-contained
(doesn't depend on code outside of xorm), minimal (can't be simplified
further) test cases. It's especially helpful if you can submit a pull
request with just the failing test case(you can find some example test file like [session_get_test.go](https://github.com/go-xorm/xorm/blob/master/session_get_test.go)).
If you implements a new database interface, you maybe need to add a test_<databasename>.sh file.
For example, [mysql_test.go](https://github.com/go-xorm/xorm/blob/master/test_mysql.sh)
### New functionality
There are a number of pending patches for new functionality, so
additional feature patches will take a while to merge. Still, patches
are generally reviewed based on usefulness and complexity in addition
to time-in-queue, so if you have a knockout idea, take a shot. Feel
free to open an issue discussion your proposed patch beforehand.

## Installation
go get github.com/go-xorm/xorm
## Documents
* [Manual](http://xorm.io/docs)
* [GoDoc](http://godoc.org/github.com/go-xorm/xorm)
## Quick Start
* Create Engine
```Go
engine, err := xorm.NewEngine(driverName, dataSourceName)
```
* Define a struct and Sync2 table struct to database
```Go
type User struct {
Id int64
Name string
Salt string
Age int
Passwd string `xorm:"varchar(200)"`
Created time.Time `xorm:"created"`
Updated time.Time `xorm:"updated"`
}
err := engine.Sync2(new(User))
```
* Create Engine Group
```Go
dataSourceNameSlice := []string{masterDataSourceName, slave1DataSourceName, slave2DataSourceName}
engineGroup, err := xorm.NewEngineGroup(driverName, dataSourceNameSlice)
```
```Go
masterEngine, err := xorm.NewEngine(driverName, masterDataSourceName)
slave1Engine, err := xorm.NewEngine(driverName, slave1DataSourceName)
slave2Engine, err := xorm.NewEngine(driverName, slave2DataSourceName)
engineGroup, err := xorm.NewEngineGroup(masterEngine, []*Engine{slave1Engine, slave2Engine})
```
Then all place where `engine` you can just use `engineGroup`.
* `Query` runs a SQL string, the returned results is `[]map[string][]byte`, `QueryString` returns `[]map[string]string`, `QueryInterface` returns `[]map[string]interface{}`.
```Go
results, err := engine.Query("select * from user")
results, err := engine.Where("a = 1").Query()
results, err := engine.QueryString("select * from user")
results, err := engine.Where("a = 1").QueryString()
results, err := engine.QueryInterface("select * from user")
results, err := engine.Where("a = 1").QueryInterface()
```
* `Exec` runs a SQL string, it returns `affected` and `error`
```Go
affected, err := engine.Exec("update user set age = ? where name = ?", age, name)
```
* `Insert` one or multiple records to database
```Go
affected, err := engine.Insert(&user)
// INSERT INTO struct () values ()
affected, err := engine.Insert(&user1, &user2)
// INSERT INTO struct1 () values ()
// INSERT INTO struct2 () values ()
affected, err := engine.Insert(&users)
// INSERT INTO struct () values (),(),()
affected, err := engine.Insert(&user1, &users)
// INSERT INTO struct1 () values ()
// INSERT INTO struct2 () values (),(),()
```
* `Get` query one record from database
```Go
has, err := engine.Get(&user)
// SELECT * FROM user LIMIT 1
has, err := engine.Where("name = ?", name).Desc("id").Get(&user)
// SELECT * FROM user WHERE name = ? ORDER BY id DESC LIMIT 1
var name string
has, err := engine.Where("id = ?", id).Cols("name").Get(&name)
// SELECT name FROM user WHERE id = ?
var id int64
has, err := engine.Where("name = ?", name).Cols("id").Get(&id)
has, err := engine.SQL("select id from user").Get(&id)
// SELECT id FROM user WHERE name = ?
var valuesMap = make(map[string]string)
has, err := engine.Where("id = ?", id).Get(&valuesMap)
// SELECT * FROM user WHERE id = ?
var valuesSlice = make([]interface{}, len(cols))
has, err := engine.Where("id = ?", id).Cols(cols...).Get(&valuesSlice)
// SELECT col1, col2, col3 FROM user WHERE id = ?
```
* `Exist` check if one record exist on table
```Go
has, err := testEngine.Exist(new(RecordExist))
// SELECT * FROM record_exist LIMIT 1
has, err = testEngine.Exist(&RecordExist{
Name: "test1",
})
// SELECT * FROM record_exist WHERE name = ? LIMIT 1
has, err = testEngine.Where("name = ?", "test1").Exist(&RecordExist{})
// SELECT * FROM record_exist WHERE name = ? LIMIT 1
has, err = testEngine.SQL("select * from record_exist where name = ?", "test1").Exist()
// select * from record_exist where name = ?
has, err = testEngine.Table("record_exist").Exist()
// SELECT * FROM record_exist LIMIT 1
has, err = testEngine.Table("record_exist").Where("name = ?", "test1").Exist()
// SELECT * FROM record_exist WHERE name = ? LIMIT 1
```
* `Find` query multiple records from database, also you can use join and extends
```Go
var users []User
err := engine.Where("name = ?", name).And("age > 10").Limit(10, 0).Find(&users)
// SELECT * FROM user WHERE name = ? AND age > 10 limit 10 offset 0
type Detail struct {
Id int64
UserId int64 `xorm:"index"`
}
type UserDetail struct {
User `xorm:"extends"`
Detail `xorm:"extends"`
}
var users []UserDetail
err := engine.Table("user").Select("user.*, detail.*").
Join("INNER", "detail", "detail.user_id = user.id").
Where("user.name = ?", name).Limit(10, 0).
Find(&users)
// SELECT user.*, detail.* FROM user INNER JOIN detail WHERE user.name = ? limit 10 offset 0
```
* `Iterate` and `Rows` query multiple records and record by record handle, there are two methods Iterate and Rows
```Go
err := engine.Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
user := bean.(*User)
return nil
})
// SELECT * FROM user
err := engine.BufferSize(100).Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
user := bean.(*User)
return nil
})
// SELECT * FROM user Limit 0, 100
// SELECT * FROM user Limit 101, 100
rows, err := engine.Rows(&User{Name:name})
// SELECT * FROM user
defer rows.Close()
bean := new(Struct)
for rows.Next() {
err = rows.Scan(bean)
}
```
* `Update` update one or more records, default will update non-empty and non-zero fields except when you use Cols, AllCols and so on.
```Go
affected, err := engine.ID(1).Update(&user)
// UPDATE user SET ... Where id = ?
affected, err := engine.Update(&user, &User{Name:name})
// UPDATE user SET ... Where name = ?
var ids = []int64{1, 2, 3}
affected, err := engine.In("id", ids).Update(&user)
// UPDATE user SET ... Where id IN (?, ?, ?)
// force update indicated columns by Cols
affected, err := engine.ID(1).Cols("age").Update(&User{Name:name, Age: 12})
// UPDATE user SET age = ?, updated=? Where id = ?
// force NOT update indicated columns by Omit
affected, err := engine.ID(1).Omit("name").Update(&User{Name:name, Age: 12})
// UPDATE user SET age = ?, updated=? Where id = ?
affected, err := engine.ID(1).AllCols().Update(&user)
// UPDATE user SET name=?,age=?,salt=?,passwd=?,updated=? Where id = ?
```
* `Delete` delete one or more records, Delete MUST have condition
```Go
affected, err := engine.Where(...).Delete(&user)
// DELETE FROM user Where ...
affected, err := engine.ID(2).Delete(&user)
// DELETE FROM user Where id = ?
```
* `Count` count records
```Go
counts, err := engine.Count(&user)
// SELECT count(*) AS total FROM user
```
* `Sum` sum functions
```Go
agesFloat64, err := engine.Sum(&user, "age")
// SELECT sum(age) AS total FROM user
agesInt64, err := engine.SumInt(&user, "age")
// SELECT sum(age) AS total FROM user
sumFloat64Slice, err := engine.Sums(&user, "age", "score")
// SELECT sum(age), sum(score) FROM user
sumInt64Slice, err := engine.SumsInt(&user, "age", "score")
// SELECT sum(age), sum(score) FROM user
```
* Query conditions builder
```Go
err := engine.Where(builder.NotIn("a", 1, 2).And(builder.In("b", "c", "d", "e"))).Find(&users)
// SELECT id, name ... FROM user WHERE a NOT IN (?, ?) AND b IN (?, ?, ?)
```
* Multiple operations in one go routine, no transation here but resue session memory
```Go
session := engine.NewSession()
defer session.Close()
user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
if _, err := session.Insert(&user1); err != nil {
return err
}
user2 := Userinfo{Username: "yyy"}
if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
return err
}
if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
return err
}
return nil
```
* Transation should on one go routine. There is transaction and resue session memory
```Go
session := engine.NewSession()
defer session.Close()
// add Begin() before any action
if err := session.Begin(); err != nil {
// if returned then will rollback automatically
return err
}
user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
if _, err := session.Insert(&user1); err != nil {
return err
}
user2 := Userinfo{Username: "yyy"}
if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
return err
}
if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
return err
}
// add Commit() after all actions
return session.Commit()
```
* Or you can use `Transaction` to replace above codes.
```Go
res, err := engine.Transaction(func(sess *xorm.Session) (interface{}, error) {
user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
if _, err := session.Insert(&user1); err != nil {
return nil, err
}
user2 := Userinfo{Username: "yyy"}
if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
return nil, err
}
if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
return nil, err
}
return nil, nil
})
```
* Context Cache, if enabled, current query result will be cached on session and be used by next same statement on the same session.
```Go
sess := engine.NewSession()
defer sess.Close()
var context = xorm.NewMemoryContextCache()
var c2 ContextGetStruct
has, err := sess.ID(1).ContextCache(context).Get(&c2)
assert.NoError(t, err)
assert.True(t, has)
assert.EqualValues(t, 1, c2.Id)
assert.EqualValues(t, "1", c2.Name)
sql, args := sess.LastSQL()
assert.True(t, len(sql) > 0)
assert.True(t, len(args) > 0)
var c3 ContextGetStruct
has, err = sess.ID(1).ContextCache(context).Get(&c3)
assert.NoError(t, err)
assert.True(t, has)
assert.EqualValues(t, 1, c3.Id)
assert.EqualValues(t, "1", c3.Name)
sql, args = sess.LastSQL()
assert.True(t, len(sql) == 0)
assert.True(t, len(args) == 0)
```

# 快速开始
* 第一步创建引擎，driverName, dataSourceName和database/sql接口相同
```Go
engine, err := xorm.NewEngine(driverName, dataSourceName)
```
* 定义一个和表同步的结构体，并且自动同步结构体到数据库
```Go
type User struct {
Id int64
Name string
Salt string
Age int
Passwd string `xorm:"varchar(200)"`
Created time.Time `xorm:"created"`
Updated time.Time `xorm:"updated"`
}
err := engine.Sync2(new(User))
```
* 创建Engine组
```Go
dataSourceNameSlice := []string{masterDataSourceName, slave1DataSourceName, slave2DataSourceName}
engineGroup, err := xorm.NewEngineGroup(driverName, dataSourceNameSlice)
```
```Go
masterEngine, err := xorm.NewEngine(driverName, masterDataSourceName)
slave1Engine, err := xorm.NewEngine(driverName, slave1DataSourceName)
slave2Engine, err := xorm.NewEngine(driverName, slave2DataSourceName)
engineGroup, err := xorm.NewEngineGroup(masterEngine, []*Engine{slave1Engine, slave2Engine})
```
所有使用 `engine` 都可以简单的用 `engineGroup` 来替换。
* `Query` 最原始的也支持SQL语句查询，返回的结果类型为 []map[string][]byte。`QueryString` 返回 []map[string]string, `QueryInterface` 返回 `[]map[string]interface{}`.
```Go
results, err := engine.Query("select * from user")
results, err := engine.Where("a = 1").Query()
results, err := engine.QueryString("select * from user")
results, err := engine.Where("a = 1").QueryString()
results, err := engine.QueryInterface("select * from user")
results, err := engine.Where("a = 1").QueryInterface()
```
* `Exec` 执行一个SQL语句
```Go
affected, err := engine.Exec("update user set age = ? where name = ?", age, name)
```
* `Insert` 插入一条或者多条记录
```Go
affected, err := engine.Insert(&user)
// INSERT INTO struct () values ()
affected, err := engine.Insert(&user1, &user2)
// INSERT INTO struct1 () values ()
// INSERT INTO struct2 () values ()
affected, err := engine.Insert(&users)
// INSERT INTO struct () values (),(),()
affected, err := engine.Insert(&user1, &users)
// INSERT INTO struct1 () values ()
// INSERT INTO struct2 () values (),(),()
```
* `Get` 查询单条记录
```Go
has, err := engine.Get(&user)
// SELECT * FROM user LIMIT 1
has, err := engine.Where("name = ?", name).Desc("id").Get(&user)
// SELECT * FROM user WHERE name = ? ORDER BY id DESC LIMIT 1
var name string
has, err := engine.Where("id = ?", id).Cols("name").Get(&name)
// SELECT name FROM user WHERE id = ?
var id int64
has, err := engine.Where("name = ?", name).Cols("id").Get(&id)
has, err := engine.SQL("select id from user").Get(&id)
// SELECT id FROM user WHERE name = ?
var valuesMap = make(map[string]string)
has, err := engine.Where("id = ?", id).Get(&valuesMap)
// SELECT * FROM user WHERE id = ?
var valuesSlice = make([]interface{}, len(cols))
has, err := engine.Where("id = ?", id).Cols(cols...).Get(&valuesSlice)
// SELECT col1, col2, col3 FROM user WHERE id = ?
```
* `Exist` 检测记录是否存在
```Go
has, err := testEngine.Exist(new(RecordExist))
// SELECT * FROM record_exist LIMIT 1
has, err = testEngine.Exist(&RecordExist{
Name: "test1",
})
// SELECT * FROM record_exist WHERE name = ? LIMIT 1
has, err = testEngine.Where("name = ?", "test1").Exist(&RecordExist{})
// SELECT * FROM record_exist WHERE name = ? LIMIT 1
has, err = testEngine.SQL("select * from record_exist where name = ?", "test1").Exist()
// select * from record_exist where name = ?
has, err = testEngine.Table("record_exist").Exist()
// SELECT * FROM record_exist LIMIT 1
has, err = testEngine.Table("record_exist").Where("name = ?", "test1").Exist()
// SELECT * FROM record_exist WHERE name = ? LIMIT 1
```
* `Find` 查询多条记录，当然可以使用Join和extends来组合使用
```Go
var users []User
err := engine.Where("name = ?", name).And("age > 10").Limit(10, 0).Find(&users)
// SELECT * FROM user WHERE name = ? AND age > 10 limit 10 offset 0
type Detail struct {
Id int64
UserId int64 `xorm:"index"`
}
type UserDetail struct {
User `xorm:"extends"`
Detail `xorm:"extends"`
}
var users []UserDetail
err := engine.Table("user").Select("user.*, detail.*")
Join("INNER", "detail", "detail.user_id = user.id").
Where("user.name = ?", name).Limit(10, 0).
Find(&users)
// SELECT user.*, detail.* FROM user INNER JOIN detail WHERE user.name = ? limit 10 offset 0
```
* `Iterate` 和 `Rows` 根据条件遍历数据库，可以有两种方式: Iterate and Rows
```Go
err := engine.Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
user := bean.(*User)
return nil
})
// SELECT * FROM user
err := engine.BufferSize(100).Iterate(&User{Name:name}, func(idx int, bean interface{}) error {
user := bean.(*User)
return nil
})
// SELECT * FROM user Limit 0, 100
// SELECT * FROM user Limit 101, 100
rows, err := engine.Rows(&User{Name:name})
// SELECT * FROM user
defer rows.Close()
bean := new(Struct)
for rows.Next() {
err = rows.Scan(bean)
}
```
* `Update` 更新数据，除非使用Cols,AllCols函数指明，默认只更新非空和非0的字段
```Go
affected, err := engine.ID(1).Update(&user)
// UPDATE user SET ... Where id = ?
affected, err := engine.Update(&user, &User{Name:name})
// UPDATE user SET ... Where name = ?
var ids = []int64{1, 2, 3}
affected, err := engine.In(ids).Update(&user)
// UPDATE user SET ... Where id IN (?, ?, ?)
// force update indicated columns by Cols
affected, err := engine.ID(1).Cols("age").Update(&User{Name:name, Age: 12})
// UPDATE user SET age = ?, updated=? Where id = ?
// force NOT update indicated columns by Omit
affected, err := engine.ID(1).Omit("name").Update(&User{Name:name, Age: 12})
// UPDATE user SET age = ?, updated=? Where id = ?
affected, err := engine.ID(1).AllCols().Update(&user)
// UPDATE user SET name=?,age=?,salt=?,passwd=?,updated=? Where id = ?
```
* `Delete` 删除记录，需要注意，删除必须至少有一个条件，否则会报错。要清空数据库可以用EmptyTable
```Go
affected, err := engine.Where(...).Delete(&user)
// DELETE FROM user Where ...
affected, err := engine.ID(2).Delete(&user)
// DELETE FROM user Where id = ?
```
* `Count` 获取记录条数
```Go
counts, err := engine.Count(&user)
// SELECT count(*) AS total FROM user
```
* `Sum` 求和函数
```Go
agesFloat64, err := engine.Sum(&user, "age")
// SELECT sum(age) AS total FROM user
agesInt64, err := engine.SumInt(&user, "age")
// SELECT sum(age) AS total FROM user
sumFloat64Slice, err := engine.Sums(&user, "age", "score")
// SELECT sum(age), sum(score) FROM user
sumInt64Slice, err := engine.SumsInt(&user, "age", "score")
// SELECT sum(age), sum(score) FROM user
```
* 条件编辑器
```Go
err := engine.Where(builder.NotIn("a", 1, 2).And(builder.In("b", "c", "d", "e"))).Find(&users)
// SELECT id, name ... FROM user WHERE a NOT IN (?, ?) AND b IN (?, ?, ?)
```
* 在一个Go程中多次操作数据库，但没有事务
```Go
session := engine.NewSession()
defer session.Close()
user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
if _, err := session.Insert(&user1); err != nil {
return err
}
user2 := Userinfo{Username: "yyy"}
if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
return err
}
if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
return err
}
return nil
```
* 在一个Go程中有事务
```Go
session := engine.NewSession()
defer session.Close()
// add Begin() before any action
if err := session.Begin(); err != nil {
// if returned then will rollback automatically
return err
}
user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
if _, err := session.Insert(&user1); err != nil {
return err
}
user2 := Userinfo{Username: "yyy"}
if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
return err
}
if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
return err
}
// add Commit() after all actions
return session.Commit()
```
* 事物的简写方法
```Go
res, err := engine.Transaction(func(sess *xorm.Session) (interface{}, error) {
user1 := Userinfo{Username: "xiaoxiao", Departname: "dev", Alias: "lunny", Created: time.Now()}
if _, err := session.Insert(&user1); err != nil {
return nil, err
}
user2 := Userinfo{Username: "yyy"}
if _, err := session.Where("id = ?", 2).Update(&user2); err != nil {
return nil, err
}
if _, err := session.Exec("delete from userinfo where username = ?", user2.Username); err != nil {
return nil, err
}
return nil, nil
})
```
* Context Cache, if enabled, current query result will be cached on session and be used by next same statement on the same session.
```Go
sess := engine.NewSession()
defer sess.Close()
var context = xorm.NewMemoryContextCache()
var c2 ContextGetStruct
has, err := sess.ID(1).ContextCache(context).Get(&c2)
assert.NoError(t, err)
assert.True(t, has)
assert.EqualValues(t, 1, c2.Id)
assert.EqualValues(t, "1", c2.Name)
sql, args := sess.LastSQL()
assert.True(t, len(sql) > 0)
assert.True(t, len(args) > 0)
var c3 ContextGetStruct
has, err = sess.ID(1).ContextCache(context).Get(&c3)
assert.NoError(t, err)
assert.True(t, has)
assert.EqualValues(t, 1, c3.Id)
assert.EqualValues(t, "1", c3.Name)
sql, args = sess.LastSQL()
assert.True(t, len(sql) == 0)
assert.True(t, len(args) == 0)
```

Package xorm is a simple and powerful ORM for Go.
Installation
Make sure you have installed Go 1.6+ and then:
go get github.com/go-xorm/xorm
Create Engine
Firstly, we should new an engine for a database
engine, err := xorm.NewEngine(driverName, dataSourceName)
Method NewEngine's parameters is the same as sql.Open. It depends
drivers' implementation.
Generally, one engine for an application is enough. You can set it as package variable.
Raw Methods
XORM also support raw SQL execution:
1. query a SQL string, the returned results is []map[string][]byte
results, err := engine.Query("select * from user")
2. execute a SQL string, the returned results
affected, err := engine.Exec("update user set .... where ...")
ORM Methods
There are 8 major ORM methods and many helpful methods to use to operate database.
1. Insert one or multiple records to database
affected, err := engine.Insert(&struct)
// INSERT INTO struct () values ()
affected, err := engine.Insert(&struct1, &struct2)
// INSERT INTO struct1 () values ()
// INSERT INTO struct2 () values ()
affected, err := engine.Insert(&sliceOfStruct)
// INSERT INTO struct () values (),(),()
affected, err := engine.Insert(&struct1, &sliceOfStruct2)
// INSERT INTO struct1 () values ()
// INSERT INTO struct2 () values (),(),()
2. Query one record or one variable from database
has, err := engine.Get(&user)
// SELECT * FROM user LIMIT 1
var id int64
has, err := engine.Table("user").Where("name = ?", name).Get(&id)
// SELECT id FROM user WHERE name = ? LIMIT 1
3. Query multiple records from database
var sliceOfStructs []Struct
err := engine.Find(&sliceOfStructs)
// SELECT * FROM user
var mapOfStructs = make(map[int64]Struct)
err := engine.Find(&mapOfStructs)
// SELECT * FROM user
var int64s []int64
err := engine.Table("user").Cols("id").Find(&int64s)
// SELECT id FROM user
4. Query multiple records and record by record handle, there two methods, one is Iterate,
another is Rows
err := engine.Iterate(...)
// SELECT * FROM user
rows, err := engine.Rows(...)
// SELECT * FROM user
defer rows.Close()
bean := new(Struct)
for rows.Next() {
err = rows.Scan(bean)
}
5. Update one or more records
affected, err := engine.ID(...).Update(&user)
// UPDATE user SET ...
6. Delete one or more records, Delete MUST has condition
affected, err := engine.Where(...).Delete(&user)
// DELETE FROM user Where ...
7. Count records
counts, err := engine.Count(&user)
// SELECT count(*) AS total FROM user
counts, err := engine.SQL("select count(*) FROM user").Count()
// select count(*) FROM user
8. Sum records
sumFloat64, err := engine.Sum(&user, "id")
// SELECT sum(id) from user
sumFloat64s, err := engine.Sums(&user, "id1", "id2")
// SELECT sum(id1), sum(id2) from user
sumInt64s, err := engine.SumsInt(&user, "id1", "id2")
// SELECT sum(id1), sum(id2) from user
Conditions
The above 8 methods could use with condition methods chainable.
Attention: the above 8 methods should be the last chainable method.
1. ID, In
engine.ID(1).Get(&user) // for single primary key
// SELECT * FROM user WHERE id = 1
engine.ID(core.PK{1, 2}).Get(&user) // for composite primary keys
// SELECT * FROM user WHERE id1 = 1 AND id2 = 2
engine.In("id", 1, 2, 3).Find(&users)
// SELECT * FROM user WHERE id IN (1, 2, 3)
engine.In("id", []int{1, 2, 3}).Find(&users)
// SELECT * FROM user WHERE id IN (1, 2, 3)
2. Where, And, Or
engine.Where().And().Or().Find()
// SELECT * FROM user WHERE (.. AND ..) OR ...
3. OrderBy, Asc, Desc
engine.Asc().Desc().Find()
// SELECT * FROM user ORDER BY .. ASC, .. DESC
engine.OrderBy().Find()
// SELECT * FROM user ORDER BY ..
4. Limit, Top
engine.Limit().Find()
// SELECT * FROM user LIMIT .. OFFSET ..
engine.Top(5).Find()
// SELECT TOP 5 * FROM user // for mssql
// SELECT * FROM user LIMIT .. OFFSET 0 //for other databases
5. SQL, let you custom SQL
var users []User
engine.SQL("select * from user").Find(&users)
6. Cols, Omit, Distinct
var users []*User
engine.Cols("col1, col2").Find(&users)
// SELECT col1, col2 FROM user
engine.Cols("col1", "col2").Where().Update(user)
// UPDATE user set col1 = ?, col2 = ? Where ...
engine.Omit("col1").Find(&users)
// SELECT col2, col3 FROM user
engine.Omit("col1").Insert(&user)
// INSERT INTO table (non-col1) VALUES ()
engine.Distinct("col1").Find(&users)
// SELECT DISTINCT col1 FROM user
7. Join, GroupBy, Having
engine.GroupBy("name").Having("name='xlw'").Find(&users)
//SELECT * FROM user GROUP BY name HAVING name='xlw'
engine.Join("LEFT", "userdetail", "user.id=userdetail.id").Find(&users)
//SELECT * FROM user LEFT JOIN userdetail ON user.id=userdetail.id
