Moin,
I have al small problem with ISNULL in a trigger
function. My definition looks like:
IF NEW.vkp ISNULL THEN
select t1.las into i_kd
from auftrag t1, aufpos t2 where
t2.auftrag = t1.id;
select get_vkp(i_kd, NEW.artikel) into f_vkp;
NEW.vkp:=f_vkp;
END IF;
The following SQL query didnt cause this if statement:
insert into aufpos(auftrag, artikel, best_menge, vkp,
lieferwoche, cuser, ctime, uuser, utime) values
('175','8501900','12','','3500','matthias',
now (), 'matthias',now ())
If I change the function statement as follows:
IF NEW.vkp = 0 THEN
...
END IF;
it works but '0' is a leagal value but not '' (empty). The
function should only be called if NEW.vkp ist empty.
Many thanks
Matthias
