Hello I need help with an update statment.
Table1: LinkID, Width, Height, UserID, Status
Table2: UserID, Credits

How can i do something like If Width * Height < Credits Then Set Status = 22.
I need to do this for each record in Table1 which is why Im having trouble writing it myself.

Thanks

update t1
set status = case when (width * height) < credits then 22 else t1.status end
from table1 t1
join table2 t2 on t1.userid = t2.userid

or, you can do it this way (probably the better approach, as only the records that meet your criteria are updated.)

update t1
set status = 22
from table1 t1
join table2 t2 on t1.userid = t2.userid
where  (width * height) < credits
