mssql_free_result

Name

mssql_free_result — Frees memory associated with a query.

Synopsis

bool mssql_free_result(result); int result: Result identifier

Returns

TRUE on success; FALSE on error

Description

mssql_free_result() can be used as a memory cleaner at any time after a query. All query results are stored in memory and are read out from memory using display functions such as mssql_fetch_row() . If you're concerned that your query may use too much memory in your script, calling mssql_free_result() will free the memory allocated to the result set. You really only need this function if you're going to be making lots of queries in a script or if your query returns large amounts of data.

Example

Example 774. Free query memory

$db = @mssql_connect("server","sa","password") or die("Unable to connect to server");
mssql_select_db("pubs");
$result = mssql_query("SELECT * FROM authors");
mssql_free_result($result);
