Package builder is a simple and powerful sql builder for Go.
|
|
|
|
Make sure you have installed Go 1.1+ and then:
|
|
|
|
go get xorm.io/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 . "xorm.io/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 . "xorm.io/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 . "xorm.io/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 . "xorm.io/builder"
|
|
|
|
sql, args, _ := ToSQL(Like{"a", "c"})
|
|
// a LIKE ? [%c%]
|
|
|
|
5. Expr you can customerize your sql with Expr
|
|
|
|
import . "xorm.io/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 . "xorm.io/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 . "xorm.io/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 . "xorm.io/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 . "xorm.io/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 . "xorm.io/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
