I have a table named “MYprojects” and a column named with “Rights”.Now i have a following row

id =>1

rights => 7,4,34,532,12,32

Now i need to delete that row if any of the number-in rights column presents in the following
value

2,4,65,34

As you can see 4 is present in the value in the column so i need to delete that row.
Can someone tell me the mysql query or function for this?
It can be done by server side scripting by applying loops but i need an optimized solution
Thanks

    You could use MySQL’s FIND_IN_SET() function (which will be particularly efficient if the Rights column is stored using the SET data-type):

    DELETE FROM MYprojects WHERE
     FIND_IN_SET( 2, Rights)
  OR FIND_IN_SET( 4, Rights)
  OR FIND_IN_SET(65, Rights)
  OR FIND_IN_SET(34, Rights)

    However, as daghan comments, you should probably consider a more suitable datastructure that takes advantage of MySQL’s relational database management capabilities.
