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"
