This is the first example in the manual page for mysql_query:

$result = mysql_query('SELECT * WHERE 1=1');
if (!$result) {
    die('Invalid query: ' . mysql_error());
}

If you wish to use something other than die, then I'd suggest trigger_error.

If your query failed  you ll receive a FALSE return value  Otherwise you ll receive a resource TRUE    result   mysql query  query    if   result          check for error  die  etc        Basically as long as it s not false  you re fine  Afterwards  you can continue your code   if   result    This part of the code actually runs your query
