sqlsrv_free_stmtFrees all resources for the specified statement


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.

Elenco dei parametri


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.

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.


Example #1 sqlsrv_free_stmt() example

$connectionInfo = array( "Database"=>"dbName""UID"=>"username""PWD"=>"password");
$conn sqlsrv_connect$serverName$connectionInfo);
$conn === false ) {
print_rsqlsrv_errors(), true));

$stmt sqlsrv_query$conn"SELECT * FROM Table_1");
$stmt === false ) {
print_rsqlsrv_errors(), true));

     Process query results here.

/* Free the statement resources. */



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.
