sqlsrv_free_stmt — Frees all resources for the specified statement
Description
sqlsrv_free_stmt
( resource $stmt
) : bool
Frees all resources for the specified statement. The statement cannot be used after sqlsrv_free_stmt() has been called on it. If sqlsrv_free_stmt() is called on an in-progress statement that alters server state, statement execution is terminated and the statement is rolled back.
Parameters
stmt- The statement for which resources are freed. Note that
NULLis a valid parameter value. This allows the function to be called multiple times in a script.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example #1 sqlsrv_free_stmt() example
<?php$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.
