sqlsrv_free_stmt

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

sqlsrv_free_stmtFrees all resources for the specified statement

Descrierea

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.

Parametri

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.

Valorile întoarse

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eșecului.

Exemple

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_rsqlsrv_errors(), true));
}

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

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

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

?>

Note

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.
