| My brain fog is particularly bad today.I have a trigger on table Activity. I want to update or insert into ActivitySummary from the trigger on the activity table. What is the most efficient way check if a record exists and therefore update else do an insert. I would have thought something like this...set @check = select activityid from activitysummary where studentsid = inserted.studentsidBut that doesn't work if many records were inserted. I can only think of cursors and I know they are evil. |
