mysql_errno() list?

Hi guys, I've been playing with PHP for a while now, and love the mysql functions, but there's one thing I'd like to know... I want to check if a mysql error is a certain number, and thats all fair enough because every time i encounter an error I can write down what that error was. However, it would be handy if I could have my own define file with all the errors in. Can I ask if anyone has a list of errors and their numbers for mysql_errno? I've looked on the web and found a load of errors for the mysql daemon (the page told me to look in /usr/share/mysql/mysql_errors.txt) but this isnt the file I want as the errors there relate to the server and not errors with a query I'm running Thanks in advance for any help James Booker EMPICS Sports Photo Agency http://www.empics.com
