DB_common::limitQuery()

Description

Executes a SQL query, but fetches only the the specificed count of rows. It is an emulation of the MySQL LIMIT option.

Parameter

Return value

mixed - a new DB_result object for queries that return results (such as SELECT queries), DB_OK for queries that manipulate data (such as INSERT queries) or a DB_Error object on failure

Throws

Note

This function can not be called statically.

Depending on the database you will not really get more speed compared to query(). The advantage of limitQuery() is the deleting of unneeded rows in the resultset, as early as possible. So this can decrease memory usage.

Example

<?php
// Once you have a valid DB object named $db...
$res =& $db->limitQuery('SELECT * FROM foo', 50, 10);

if (DB::isError($res)) {
    die($res->getMessage());
}
?>
