Easy Firebird question

Hello, i hope my question is not to stupid, but i have sometimes to deal with our firebird database and just need quick help:

How to update values with a join condition:

"
select Vauftragnr, Kundname, Lager from wws_verkauf1
join wws_verkauf2 on wws_verkauf1.VAUFTRAGNR = wws_verkauf2.VAUFTRAGNR
where artikelnr="30000" and datum>"01.01.2018" and erledigt="N"
"

i would like to update the "Lager"

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Firebird does not support joins in an update statement. You need to locate the wanted rows to update using the where clause instead. E.g. by using EXISTS

Before I could try a rewrite I would need to know which tables these columns come from:

where artikelnr="30000" and datum>"01.01.2018" and erledigt="N"

nb It is really important to preface columns by the table in any multi-table query.
