If that's so, why would you expect the first query to return more than one row? Do you mean you want entries that have M *or* W *or* F? mysql select schdays from courses where schdays LIKE %MWF%; +-+ | schdays | +-+ | MWF | +-+ 1 row in set (0.00 sec) mysql select schdays from courses where schdays LIKE %M%; +-+ | schdays | +-+ | MWF | | MW | | MW | | M | | M | +-+ 5 rows in set (0.00 sec) Thanks in advance, Douglas -- Douglas R.

RE: Please Help with Pattern Matching
Doug, MySql is doing what it is supposed to... If you specify '%MWF%' it will only select the values with the string literal 'MWF' in it. If you would like to match all the rows that have either M or W or F in it, then use a query like : select schdays from courses where schdays LIKE %M% OR LIKE %W% OR LIKE %F%; This will return every row that has either M or W or F in the schdays field.

Re: Please Help with Pattern Matching
In the last episode (Jan 29), Douglas Brantz said: I have a big problem with pattern matching; Why does the first example work like this I need to find everything with MWF in it and I only get the 1 entry? Is there a way I can make this work. mysql select schdays from courses where schdays LIKE %MWF%; | MWF | mysql select schdays from courses where schdays LIKE %M%; | MWF | | MW | | MW | | M | | M | I see nothing wrong here. Your first statement says give me all rows with the string MWF in schdays. Your second statement says give me all rows with the string M in schdays. If you want all rows with M, W, or F in schdays, you'll want something like WHERE schdays LIKE %M% OR schdays LIKE %W% OR schdays LIKE %F%. -- Dan Nelson [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
