指示结果集是否具有一行或多行。在 SQL Server Driver for PHP 的 1.1 版中添加了此功能。SQL Server Driver for PHP 的 1.0 版的用户可通过使用在如何检测空结果集中描述的技术，检测到空的结果集。
<?php
$server = "server_name";
$conn = sqlsrv_connect( $server, array( 'Database' => 'Northwind' ) );
$stmt = sqlsrv_query( $conn, "select * from orders where CustomerID = 'VINET'" , array());
if ($stmt !== NULL) {
$rows = sqlsrv_has_rows( $stmt );
if ($rows === true)
echo "\nthere are rows\n";
else
echo "\nno rows\n";
}
?>
