In Slick 2.1 I had the code below to execute an sql-query from a file:
def fetchResult[T](sql: String)(implicit getResult: GetResult[T]): List[T] = {
val query = Q.queryNA[T](sql)
try {
Database.forDataSource(DB.getDataSource())
.withSession { implicit session => query.list }
}
catch {
case e: Throwable =>
throw new RunSqlException(s"Query $name execution error", e)
}
}
In Slick 3.0.0 you use dbConfig.db.run method to execute DBIOAction and get a future of the result. But I can't find a way to transform result of Q.queryNA (which is StaticQuery[Unit, R]
) into DBIOAction
. Does such a way exist?
I ended up with deprecated calls for now. Help me be better!
def fetchResult[T](sql: String)(implicit getResult: GetResult[T]): Future[List[T]] = Future {
val query = Q.queryNA[T](sql)
try {
this.dbConfig.db.withSession { implicit session => query.list }
}
catch {
case e: Throwable =>
throw new RunSqlException(s"Query $name execution error", e)
}
}
Only solution I managed to find was a bit hackish:
