sqlsrv_commit — Commits a transaction that was begun with sqlsrv_begin_transaction()

说明

sqlsrv_commit ( resource $conn ) : bool

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 commit/roll back transactions. For more information, see » SQLSRV Transactions.

参数

conn

The connection on which the transaction is to be committed.

返回值

成功时返回 true， 或者在失败时返回 false。

范例

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_r( sqlsrv_errors(), true ));}/* Begin the transaction. */if ( sqlsrv_begin_transaction( $conn ) === false ) {     die( print_r( sqlsrv_errors(), true ));}/* Initialize parameter values. */$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 />";}?>
