you are right with "auswerten / überprüfen", but, - there it is capped as well.
Sure, I can write to a log file, what I wanted to avoid.
Unfortunately you will not be able to help me.
I see an error-message, a value would be NULL, which is not.
And I see it, where it has worked before since years. :'(
I build this SQL-statement by a method, which is two pages long. Grabs the data from other units.
How I hate it to touch it.
At the moment I have no idea, how to work on.
