是否可以使用连接到 Windows 服务器数据库的 SQLSRV 从 PHP 中的存储过程返回数据。目前，我的代码成功提交了查询，但没有返回任何内容。行输出甚至不运行一次的循环（即对象为空）

这是PHP

/* Set up and execute the first query. */
$sql1 = "
USE CRDCMS2PublicDevelopment
EXEC SearchForXML6b 
@SessionID = 973543,
@LineID = 892245,
@SortOrder = 'YearPublished DESC, SortTitle ASC',
@PageNumber = 1,
@RecordsPerPage = 20
";
$params1 = array( $orderId, $qty, $productId );
$stmt1 = sqlsrv_query( $conn, $sql1/*, $params1*/ );

/* Display the value of the output parameters. */   
while ( $obj = sqlsrv_fetch_object( $stmt1 ) ) {       
    //SET PARAMETERS - SET TERMS    
    echo 'loop';  
    echo $obj->listingXML;
}

/* If both queries were successful, commit the transaction. */
/* Otherwise, rollback the transaction. */
if( $stmt1 ) {
     sqlsrv_commit( $conn );
     echo "Transaction committed.<br />";
} else {
     sqlsrv_rollback( $conn );
     echo "Transaction rolled back.<br />";
}

这是存储过程

            '+LTRIM(RTRIM(STR(@PageNumber)))+' as "@PageNumber",
            '+LTRIM(RTRIM(STR(@RecordsPerPage)))+' as "@RecordsPerPage",

            (   SELECT dbo.GetRecordForListingXML(AccessionNumber, RowNumber,ISNULL(Selected,0)) 
                FROM @t T
                WHERE T.RowNumber > @startRow and T.RowNumber < @endRow

                FOR XML PATH(''''), ELEMENTS, TYPE
            )
            FOR XML PATH(''listing''), ELEMENTS
        )

        SELECT @XML as listingXML'

    -- ----------------------------------------------------------------------------------------------
    -- Run the SQL to extract the results as XML
    -- ----------------------------------------------------------------------------------------------

    PRINT @sql

    EXEC sp_executesql @sql

END

请注意：如果我复制并粘贴 php ($sql1) 中使用的确切 sql，它会在 SQL Server Management Studio 中正确返回一行。我认为我正在尝试可以完成，这是正确的方法吗？

谢谢。

看起来所有存储过程都在构建变量@sql。

尝试在存储过程的底部添加：

EXEC @sql
