Question

我正在将SQL查询转换为光滑的DSL。我陷入了时间戳转换。我的SQL查询是：

Select isActive from users where create_time <= TIMESTAMPADD(MINUTE,
${AUTO_EXPIRY_DB_DAYS * HOURS_24 * MINUTES_60}, sysdate())
and isVerified=false;

如何编写一个相同的查询？

userQuery.filter(user => user.isVerified === FALSE && user.createdDate
<= ?????).map(_.isActive)

看看标量数据库函数slick documentation。我想这应该起作用：

val sysdate = SimpleLiteral[java.sql.Timestamp]("sysdate")
val timestampAdd = SimpleFunction.ternary[String, Int, java.sql.Timestamp, java.sql.Timestamp]("TIMESTAMPADD")

userQuery
    .filter(user => user.isVerified === FALSE 
                && user.createdDate <= timestampAdd("MINUTE", 20, sysdate))
    .map(_.isActive)
