+# SQL builder
+
+[![CircleCI](https://circleci.com/gh/go-xorm/builder/tree/master.svg?style=svg)](https://circleci.com/gh/go-xorm/builder/tree/master)
+
+Package builder is a lightweight and fast SQL builder for Go and XORM.
+
+Make sure you have installed Go 1.1+ and then:
+
+    go get github.com/go-xorm/builder
+
+# Insert
+
+```Go
+sql, args, err := Insert(Eq{"c": 1, "d": 2}).Into("table1").ToSQL()
+```
+
+# Select
+
+```Go
+sql, args, err := Select("c, d").From("table1").Where(Eq{"a": 1}).ToSQL()
+
+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()
+```
+
+# 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()
+```
+
+# 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
