Filtering zero values only if both columns are zero

Question

I need the table to exclude rows where rw.amount <> 0 AND rw.paid_subs <> 0 but still include any row that has values in either column.

I am rather clueless with SQL tables, so I have been blindly guessing at how to code this.

AND rw.amount <> 0 
AND rw.paid_subs <> 0

Answer 1

Your logic is correct, but using DeMorgan's Laws we can rewrite your exclusion logic as:

SELECT *
FROM yourTable
WHERE amount = 0 OR paid_subs = 0;
