I have written this very simple code
object PersonDAO {
val db = Database.forConfig("h2mem1")
val people = TableQuery[People]
def checkTable() : Boolean = {
val action = MTable.getTables
val future = db.run(action)
val retVal = future map {result =>
result map {x => x}
}
val x = Await.result(retVal, Duration.Inf)
if (x.length > 0) {
true
} else {
false
}
}
}
However this always fails with error message
play.api.UnexpectedException: Unexpected exception[JdbcSQLException: Invalid value 7 for parameter columnIndex [90008-60]]
