RE: [PHP-DB] mySQL Query and blank fields

First, I wouldn't use length(), I'd use REGEXP: SELECT * FROM foo_table WHERE fieldname REGEXP '..+' It's quicker. As far as the second question, do you wish to do it in PHP or MySQL? Does the value in MySQL require other computations (so, it must remain numeric) or can it be a CHAR string? -----Original Message----- From: Niklas Lampén [mailto:niklas.lists@publico.fi] Sent: Thursday, October 25, 2001 8:04 AM To: Php-DB Subject: RE: [PHP-DB] mySQL Query and blank fields Thanks a lot! I quite didn't know what to look for in the manual. I actually have another question: If I want to update several fields, add a number to the end of the fields value, how do I do that? I have field with value '9876' and if I do "...field=field+'5'..." the value turns into '9881' not '98765' as I expected.
