I think you are missing something.
>From the Manual:
FIND_IN_SET(str,strlist)
Returns a value 1 to N if the string str is in the list strlist
consisting of N substrings. A string list is a string composed of
substrings separated by `,'
characters. If the first argument is a constant string and the
second is a column of type SET, the FIND_IN_SET() function is optimised
to use bit arithmetic!
Returns 0 if str is not in strlist or if strlist is the empty
string. Returns NULL if either argument is NULL. This function will not
work properly if the first
argument contains a `,':
mysql> SELECT FIND_IN_SET('b','a,b,c,d');
-> 2

I don't know what exactly you're trying to acheive, but I'm pretty sure
FIND_IN_SET is not what you are looking for.
Can you give table descriptions and what is the data you want at the end
of your query?
