Introduction - Query -- Performing a query against a database.
Description
To perform a query against a database, you have to use the function query(), that takes the query string as an argument. On failure you get a
MDB_Error object. Be sure to check it with
MDB::isError(). On success, you get MDB_OK or when you set a SELECT-statment a result resource handle
<?php // Once you have a valid MDB object... $sql = "select * from clients"; $result = $db->query($sql); // Always check that $result is not an error if (MDB::isError($result)) { die ($result->getMessage()); } // Continue on with your script ?>
