Question

I a have a MySQL db with 4 fields:

id | planchanged | dataremoved | rolloverenabled |
1  | Yes         | Yes         | Yes             |
2  | NULL        |             |                 |
3  |             | Yes         |                 |
4  | Yes         |             | Yes             |
5  |             |             | NULL            |

How do I query this db to show only records that doesn’t have all ‘Yes’ on those three fields. Please also take into consideration that some of thos fields might be Null. So based on that example my result should show records 2,3,4 and 5.

Answer 1

SELECT * 
FROM yourTableName 
WHERE planchanged IS NULL OR planchanged <> 'Yes' 
OR dataremoved IS NULL OR dataremoved <> 'Yes' 
OR rolloverenabled IS NULL OR rolloverenabled <> 'Yes'
