(No version information available, might only be in Git)

sqlsrv_free_stmt — Frees all resources for the specified statement

Description

bool sqlsrv_free_stmt ( resource $stmt )

Frees all resources for the specified statement. The statement cannot be used after sqlsrv_free_stmt() has been called on it. If sqlsrv_free_stmt() is called on an in-progress statement that alters server state, statement execution is terminated and the statement is rolled back.

Parameters

stmt

The statment for which resources are freed. Note that NULL is a valid parameter value. This allows the function to be called multiple times in a script.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 sqlsrv_free_stmt() example

<?php
$serverName = "serverName\sqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
     die( print_r( sqlsrv_errors(), true));
}

$stmt = sqlsrv_query( $conn, "SELECT * FROM Table_1");
if( $stmt === false ) {
     die( print_r( sqlsrv_errors(), true));
}

/*-------------------------------
     Process query results here.
-------------------------------*/

/* Free the statement resources. */
sqlsrv_free_stmt( $stmt);

?>

Notes

The main difference between sqlsrv_free_stmt() and sqlsrv_cancel() is that a statement resource cancelled with sqlsrv_cancel() can be re-executed if it was created with sqlsrv_prepare(). A statement resource cancelled with sqlsrv_free_statement() cannot be re-executed.
