MySQL regex for matching comma seperated values
I have a string matching question that is beyond my knowledge when it comes to regex in mysql.
The Situation:
I have a rather large table with csv fields that needs to be searched and I need to be able to match rows according to 1+ user specified search terms. For example the user needs to be able to search for clock and radio. The issue is that I only want it to match separate comma separated values. So searching for clock and radio would only match were the field contains "clock, whatever, radio" and not "clock radio"
My thinking:
I need a regular expression that will match;
- the beginning of the string, a comma, or a space
- search term 1
- zero or more spaces
- then either a comma or the end of the string
then an OR and the same thing for search term 2.
Thank you in advance

Here's what I'm doing
SELECT * FROM `myTable` WHERE `bedroom` REGEXP (^|,|[:space:])clock[[:spa
I altered you expression slightly because, I believe what you sent you would have mathched comma AND space vs. comma or space. But obviously I could be wrong.
MySQL said:
ERROR: Unknown Punctuation String @ 56
STR: ^|
Where did I screw up?
BTW I'm using mysql 4.1
