返回上次执行的语句所修改的行数。此函数不返回 SELECT 语句返回的行数。
下面的示例显示 UPDATE 语句修改的行数。此示例假定本地计算机上已安装 SQL Server 和 AdventureWorks 数据库。从命令行运行此示例时，所有的输出都将写入控制台。
<?php
/* Connect to the local server using Windows Authentication and
specify the AdventureWorks database as the database in use. */
$serverName = "(local)";
$connectionInfo = array( "Database"=>"AdventureWorks");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false )
{
echo "Could not connect.\n";
die( print_r( sqlsrv_errors(), true));
}
/* Set up Transact-SQL query. */
$tsql = "UPDATE Sales.SalesOrderDetail
SET SpecialOfferID = ?
WHERE ProductID = ?";
/* Set parameter values. */
$params = array(2, 709);
/* Execute the statement. */
$stmt = sqlsrv_query( $conn, $tsql, $params);
/* Get the number of rows affected and display appropriate message.*/
$rows_affected = sqlsrv_rows_affected( $stmt);
if( $rows_affected === false)
{
echo "Error in calling sqlsrv_rows_affected.\n";
die( print_r( sqlsrv_errors(), true));
}
elseif( $rows_affected == -1)
{
echo "No information available.\n";
}
else
{
echo $rows_affected." rows were updated.\n";
}
/* Free statement and connection resources. */
sqlsrv_free_stmt( $stmt);
sqlsrv_close( $conn);
