Question

I have a VARCHAR column that contains comma separated values and I would like to know if I could match a number within these comma separated values?

Like, I would have a row:

id | numbers
1  | 1,2,4,5
2  | 2,3,4,6

And I would like to match all the rows with the number 2 in the list.

Answer 1

Take a look at the FIND_IN_SET function.

SELECT *
    FROM YourTable
    WHERE FIND_IN_SET('2', numbers) <> 0
