Hello
When I select table1.colA + table2.colA it return null value when colA is 0
At table1.colA and table2.colA I already use isnull function to convert null to 0 before
Please suggest.
Thank you very much.

Would you be able to provide a little more information to your situation? Some sample data and the SQL you use that generates the NULL value would be very helpful.

It will return if either of the operands have null. You said you are using isnull, but the code you have shown doesnt have that.

Hi
Can you provide with some data of each table so that i can get some idea...
for the time being if any side of the column have null value result will be null

That could happen if you are using an OUTER join and one of the tables has a row that does not have a corresponding row in the other table.
