原生SQL
sqala支持使用原生SQL,需要使用sql
插值器:
scala
val x = 1
val y = "abc"
val nativeSql = sql"select * from t where x = $x and y = $y"
sql
插值器支持+
运算,方便进行条件拼接:
scala
val x = 1
val y = "abc"
var nativeSql = sql"select * from t where true "
if x > 0 then nativeSql += sql"and x = $x "
if y.nonEmpty then nativeSql += sql"and y = $y"
我们可以使用fetchTo
方法来查询原生SQL:
scala
case class Result(x: Int, y: String)
val result = db.fetchTo[Result](nativeSql)
