Andy, I mentioned in my previous email that I am using PHP, and I have also tried putting quotes around $var (many different ways) with no better results. REGEXP just gives a syntax error when I do this.
Through the suggestion of another list user I have found a way that suits my needs using the "where name like binary '$var'". It's jury rigged, but works the way I need it to work for the most part. Thanks for your suggestions. ----- Original Message ----- From: "Andy Bakun" <[EMAIL PROTECTED]> To: "Beauford.2003" <[EMAIL PROTECTED]> Cc: "MySQL List" <[EMAIL PROTECTED]> Sent: Monday, December 09, 2002 3:08 PM Subject: Re: Select * From table where name Like 'help'; Help > You still have not mentioned what language you are using to interface > with MySQL.
