I have an instead of trigger for update on particular table which adds
3 or so columns and puts the total in a 4th No matter what the input is
(as long as there is one NULL) the total is always NULL. More than
likely is that only one of the fields has a value in it and the rest
null but i don't want to do the MAX in case that is not true.


a quick visual aid from input and desired output

Input Data
colA colB ColC tot
5 NULL NULL NULL

Current Output
colA colB ColC tot
5 NULL NULL NULL

Desired Output
colA colB ColC tot
5 NULL NULL 5

How do i Manipulate the TSQL command to work correctly?


Update tbl_lossChecks
SET
clc_totalFees = Inserted.mny_LegalFees + Inserted.mny_AdjusterFees +
Inserted.mny_Expense ,
