Is there a way to observe an SQL statement that will be generated by Query ? For example, I have this: val q = actions.filter(v => v.actionHash === hash && v.carriedAt > past) Can I view its underlying raw SQL? Ende Neu Slick 2.X: You can print the query statement as shown on the Slick documentation : val invoker = q.invoker val statement = q.selectStatement For other type of statements look at insertStatement , deleteStatement and updateStatement . Slick 3.X: val res = table.filter(_.id === 1L).result res.statements.foreach(println) Docs . For slick 3.0 println(sortedQuery.result.statements

I have nested classes/objects and want to store (and retrieve) them in a database by using SLICK. I understand that with SLICK mapped projection would be key. Furthermore I use a companion object to map between nested objects and flat structure (to be stored in the DB table). I want to do something like this (simplified example): case class Foo(id: Int, myBar: Bar) case class Bar(myInt: Int, myString: String) object Foo { def apply(id: Int, myInt: Int, myString: String): Foo = Foo(id, Bar(myInt, myString)) override def unapply(f: Foo) = (f.id, f.myBar.myInt, f.myBar.myString) } object TTable

I'm trying to insert if not exists, I found this post for 1.0.1, 2.0. I found snippet using transactionally in the docs of 3.0.0 val a = (for { ns <- coffees.filter(_.name.startsWith("ESPRESSO")).map(_.name).result _ <- DBIO.seq(ns.map(n => coffees.filter(_.name === n).delete): _*) } yield ()).transactionally val f: Future[Unit] = db.run(a) I'm struggling to write the logic from insert if not exists with this structure. I'm new to Slick and have little experience with Scala. This is my attempt to do insert if not exists outside the transaction... val result: Future[Boolean] = db.run(products
