sqlsrv_commit — Commits a transaction that was begun with sqlsrv_begin_transaction()
$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.
conn
The connection on which the transaction is to be committed.
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
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 ));
}
if ( sqlsrv_begin_transaction ( $conn ) === false ) {
die( print_r ( sqlsrv_errors (), true ));
}
$orderId = 1 ; $qty = 10 ; $productId = 100 ;
$sql1 = "INSERT INTO OrdersTable (ID, Quantity, ProductID)
VALUES (?, ?, ?)" ;
$params1 = array( $orderId , $qty , $productId );
$stmt1 = sqlsrv_query ( $conn , $sql1 , $params1 );
$sql2 = "UPDATE InventoryTable
SET Quantity = (Quantity - ?)
WHERE ProductID = ?" ;
$params2 = array( $qty , $productId );
$stmt2 = sqlsrv_query ( $conn , $sql2 , $params2 );
if( $stmt1 && $stmt2 ) {
sqlsrv_commit ( $conn );
echo "Transaction committed.<br />" ;
} else {
sqlsrv_rollback ( $conn );
echo "Transaction rolled back.<br />" ;
}
?>
