I'm trying to update some rows of my database using the following script which works pretty fine :
update DOS
set NAMEDOS=:name,
AGEDOS=:age,
WEIGHTDOS=:weight
where CODEDOS=:code
My problem is the following, sometimes the weight can be empty or null, so i have to just set the other properties.
I have tried to proceed like this, but it doesn't seems to work:
update DOS
set NAMEDOS=:name,
AGEDOS=:age,
WEIGHTDOS= (case when weight is not null then :weight else :WEIGHTDOS end),
where CODEDOS=:code
Can you help me please.
Try switching the brackets a bit and i think that :WEIGHTDOS
should be without the double dots as its the direct column name not a parameter:
update DOS
set NAMEDOS=:name,
AGEDOS=:age,
WEIGHTDOS= case when (:weight is not null) then :weight
else WEIGHTDOS
end,
where CODEDOS=:code
