From: Operating system: Debian Lenny PHP version: 5.2.13 Package: PDO related Bug Type: Bug Bug description:SQLSTATE[HY093]: Invalid parameter number (error in docs or calculation)
Description: ------------ I get the following PDOException when executing a prepared statement: SQLSTATE[HY093]: Invalid parameter number: parameter was not defined This behaviour changed in PHP after version 5.2.0 and a related issue #40417 exists. However, nothing in the documentation specifies that you can't bind MORE variables than are used in the SQL. For example if you call $statement->execute($_POST), you might bind more variables than are used in the SQL. Test script: --------------- $params = array(':key1' => 'value1', ':key2' => 'value2'); $stmt = $db->prepare('SELECT * FROM table WHERE id=:key1'); $stmt->execute($params); Expected result: ---------------- I expect this to succeed. We relied on this feature in much of our old code working up to PHP version 5.2.0, but have made a workaround in our DB layer which parses the SQL.
