MySql : Select statement using IN operator

Question

I have a table with several fields and one field having 3 Comma Separated Values

 Column 1 Column 2 
    1        1,2,3
    2        2,3,4
    3        6,7,8         


        

Answer 1

You can use FIND_IN_SET():

SELECT column1 FROM table WHERE FIND_IN_SET('2', column2) != 0

The IN operator is basically a shortcut for lots of ORs:

WHERE column2 = IN ('a', 'b', 'c')

gives the same result as

WHERE (column2 = 'a' OR column2 = 'b' OR column2 = 'c')
