mysql_unbuffered_query()

mysql_unbuffered_query - Send an SQL query to MySQL without fetching and buffering the result rows.

Syntax

resource mysql_unbuffered_query (string $query, resource $link_identifier)

Arguments

• query - The SQL query to execute. Data inside the query should be properly escaped.
• link_identifier - The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If no connection is found or established, an E_WARNING level error is generated.

Description

mysql_unbuffered_query() sends the SQL query query to MySQL without automatically fetching and buffering the result rows as mysql_query() does. This saves a considerable amount of memory with SQL queries that produce large result sets, and you can start working on the result set immediately after the first row has been retrieved as you don't have to wait until the complete SQL query has been performed. To use mysql_unbuffered_query() while multiple database connections are open, you must specify the optional parameter link_identifier to identify which connection you want to use.

Version

PHP 4.0.6, 5

Return value

For SELECT, SHOW, DESCRIBE or EXPLAIN statements, mysql_unbuffered_query() returns a resource on success, or FALSE on error.
