Well, if you enabled error logging to a flat file on your server you could just go open that in notepad... otherwise you'd have to edit libs/mysql.inc.php (going off the top of my head, your mileage may vary) and it should have a line "show_errors" that you'll need to change to 1 vs 0 (be sure to change it back after you're done otherwise you may have some security issues to deal with later)
