comma-separated

Just ran into a problem

I know these integers, $integers: 3,5,15,20

I only want to select the rows from this following table where all comma separated INT's from the field NUMBERS are found.

TABLE: number_table
Uid Numbers
------------------------
1   3,5,15    OK, since all of NUMBERS are in $integers
2   5,15,20   OK, since all of NUMBERS are in $integers
3   3,4,5,15  NOT OK, since 4 is not found in $integers
4   2,15,20,25  NOT OK, since 2 and 25 is not found in $integers

Is it possible to to a "for-each" on a comma separated string or another way to do this SELECT?
