Hint: when looking for missing data, the test "is null" can be very handy.

If it helps you can actually indent your SQL statements Gurveer

For example using Steven's hint:

SELECT [[ all ]]
FROM [[table]]
WHERE [[column]] IS NULL

Also be sure to share you code with explanation next time for quicker responses! :smile:
