Slick:如何根据isBefore时间戳数据库属性进行过滤？

import slick.jdbc.MySQLProfile.api._
import java.sql.Timestamp

case class MyTable(id: Int, timestamp: Timestamp)
class MyTableTable(tag: Tag) extends Table[MyTable](tag, "my_table") {
  def id = column[Int]("id", O.PrimaryKey)
  def timestamp = column[Timestamp]("timestamp")
  def * = (id, timestamp) <> (MyTable.tupled, MyTable.unapply)
}
val myTableQuery = TableQuery[MyTableTable]

val targetTimestamp: Timestamp = ???
val filteredQuery = myTableQuery.filter(_.timestamp < targetTimestamp)

val result = db.run(filteredQuery.result)
