Question

i have the following MySQL-Query:

$sql = "SELECT `eid` FROM `"._ST_EVENT."` WHERE `tid` = ".$tid." AND DATE(`zeitpunkt`) >= CURDATE() ORDER BY `zeitpunkt` ASC;";

The variable $tid could be NULL, but should be interpreted as ‘0’. Is it possible to do this directly in the mysql-query or should i have a if-clause like this before executing the query?

if ($tid == NULL) {
    $tid = 0;
}

Thanks!

Answer 1

Or:

$sql = "SELECT `eid` FROM `"._ST_EVENT."` WHERE `tid` = ".(!$tid ? 0 : $tid)." AND DATE(`zeitpunkt`) >= CURDATE() ORDER BY `zeitpunkt` ASC;";
