选择两列不能同时为0的行

Question

I have mysql table full of songs. Every row has column minutes and column seconds. What I want to do is create query for selecting all songs that don't have both columns set to zero(minutes = 0 && seconds = 0). But at the same time I want to collect all songs that have 0 minutes and x seconds || x minutes and 0 seconds.

Answer 1

Pretty straightforward

SELECT * FROM Songs WHERE NOT(minutes = 0 AND seconds = 0)

There are couple more solutions @GordonLinoff suggested one also:

SELECT * FROM Songs WHERE minutes <> 0 OR seconds = 0
