Question

Is it possible to update the cell value only to the specific maximum value? Here is query:

UPDATE table_1 SET premium_photos = premium_photos + 2 WHERE number = '1234'

I want to limit premium_photos (tinyint) value to max value of 4. Is it possible? For example if premium_photos current value is 2 and query is + 3, then after this query value will be 4.

Answer 1

you can also use IF function

UPDATE table_1 SET
   premium_photos = IF(premium_photos+2>4, 4, premium_photos+2)
WHERE number = '1234'
