Question

This is an example of what I want to do:

I have a table called: TEST it has two columns: ColA and ColB

It has the following data:

ColA  ColB
----  ----
0     1
0     1
0     3
2     1
2     3

I want to retrieve all values where ColA > 0, except I want to still include rows where ColA = 0 if ColB = 3

Answer 1

The following should work:

SELECT   *
FROM     TEST
WHERE    ColA > 0 --All rows where ColA > 0
OR       (ColA = 0 AND ColB = 3) -- All rows where ColA = 0 AND ColB = 3
