Not is SQL, the single character wildcard is the underscore. In SQL the ? is usually used for argument replacement, much like the %s in printf.

It's usually used as a single character wildcard. So "something = ?" would match "A", "B", "1", etc.. but not "AB, "A1". -TG = = = Original message = = = In the some code I'm working with I see many database queries using the PEAR DB class where "?" is used for a value in the SQL. What is the rule for using "?" in this way what value does it take. Example code.

    $ticket=$db->getRow(
           "SELECT id,department,from, cc, bcc FROM tickets WHERE

id=?",

           array($tid)
       );
