Descrizione

bool sqlsrv_commit ( resource $conn )

Commits a transaction that was begun with sqlsrv_begin_transaction(). The connection is returned to auto-commit mode after sqlsrv_commit() is called. The transaction that is committed includes all statements that were executed after the call to sqlsrv_begin_transaction(). Explicit transactions should be started and committed or rolled back using these functions instead of executing SQL statements that begin and committ/roll back transactions. For more information, see » SQLSRV Transactions.

Elenco dei parametri

Example #1 sqlsrv_commit() example

The following example demonstrates how to use sqlsrv_commit() together with sqlsrv_begin_transaction() and sqlsrv_rollback().

<?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 ));
}

/* Begin the transaction. */
if ( sqlsrv_begin_transaction$conn ) === false ) {
     die( 
print_rsqlsrv_errors(), true ));
}

/* Initialize parameter values. */
$orderId 1$qty 10$productId 100;

/* Set up and execute the first query. */
$sql1 "INSERT INTO OrdersTable (ID, Quantity, ProductID)
         VALUES (?, ?, ?)"
;
$params1 = array( $orderId$qty$productId );
$stmt1 sqlsrv_query$conn$sql1$params1 );

/* Set up and execute the second query. */
$sql2 "UPDATE InventoryTable 
         SET Quantity = (Quantity - ?) 
         WHERE ProductID = ?"
;
$params2 = array($qty$productId);
$stmt2 sqlsrv_query$conn$sql2$params2 );

/* If both queries were successful, commit the transaction. */
/* Otherwise, rollback the transaction. */
if( $stmt1 && $stmt2 ) {
     
sqlsrv_commit$conn );
     echo 
"Transaction committed.<br />";
} else {
     
sqlsrv_rollback$conn );
     echo 
"Transaction rolled back.<br />";
}
?>
