ID: 62348 Comment by: adamjonr at gmail dot com Reported by: valentiny510 at yahoo dot es Summary: mysqli query does not return false on DELETE Status: Open Type: Bug Package: MySQLi related Operating System: XP PHP Version: 5.4.4 Block user comment: N Private report: N New Comment: The mysqli query returns false for failed queries and true for successful queries that don't involve SELECT, SHOW, DESCRIBE or EXPLAIN (i.e., DELETE queries return true when "successful".) DELETE queries can impact 0, 1, or multiple rows, and their completion without error is, at least in the terms of the mysqli library, considered a success. http://www.php.net/manual/en/mysqli.query.php If you want to alter the flow of your script depending on whether a row has been deleted, you can use $mysqli->affected_rows to retrieve the number of rows impacted by the last DELETE, INSERT, or UPDATE statement: http://php.net/manual/en/mysqli.affected-rows.php Previous Comments: ------------------------------------------------------------------------ [2012-06-18 00:14:46] valentiny510 at yahoo dot es Description: ------------ Honestly, i'm not realy sure if is php or mysql thing..
