DeadlySilence, read my own text I know that.
But I do not need any variables where I do my coding from the SQL. Thats why I asked if there is a way, like in PHP with @, to have one line where I know that this will produce a warning that is not wanted because it is intended, to block those warnings from that line.
But if not, I seem to just to fill in a never used variable... :/ useless server impact.
