You can actually just do this:

$result = mysql_query($sql) or die(mysql_error());

if mysql_query() returns false, then the second part of the or will be
executed. There you have your error message.

Of course, it's your funural if you leave the die() in there
post-launch. A creative use of constants and another OR could get
around this problem, though.
