PHP中具有正确错误检测的Mysql查询

Posted 2021-02-26

Dumps whole query so developer can see where is error. However it's potential security issue, exposing SQL commands to attacker. (Recommended to use only during development, replace message code with some custom error text)

$sql="select something from something_else";
$res_id=mysql_query($sql);
if (!$res_id) {
	$message  = 'Invalid query: ' . mysql_error() . "
";
        $message .= 'Whole query: ' . $sql;
        die($message);
}
