sqlsrv_commit - 提交以sqlsrv_begin_transaction()开始的事务
描述
bool sqlsrv_commit ( resource $conn )

conn
要提交事务的连接。
返回值
成功时返回TRUE
或失败时返回FALSE
。
例子
示例#1 sqlsrv_commit()示例
以下示例演示如何将sqlsrv_commit()
与sqlsrv_begin_transaction()和sqlsrv_rollback()一起使用。
<?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 />";
}
?>
