Question

我在这个MSDN页面上使用类似于示例C的东西： http://msdn.microsoft.com/en-us/library/ms190307.aspx

DECLARE @tableHTML  NVARCHAR(MAX) ;

SET @tableHTML =
    N'<H1>Work Order Report</H1>' +
    N'<table border="1">' +
    N'<tr><th>Work Order ID</th><th>Product ID</th>' +
    N'<th>Name</th><th>Order Qty</th><th>Due Date</th>' +
    N'<th>Expected Revenue</th></tr>' +
    CAST ( ( SELECT td = wo.WorkOrderID,       '',
                    td = p.ProductID, '',
                    td = p.Name, '',
                    td = wo.OrderQty, '',
                    td = wo.DueDate, '',
                    td = (p.ListPrice - p.StandardCost) * wo.OrderQty
              FROM AdventureWorks.Production.WorkOrder as wo
              JOIN AdventureWorks.Production.Product AS p
              ON wo.ProductID = p.ProductID
              WHERE DueDate > '2004-04-30'
                AND DATEDIFF(dd, '2004-04-30', DueDate) < 2 
              ORDER BY DueDate ASC,
                       (p.ListPrice - p.StandardCost) * wo.OrderQty DESC
              FOR XML PATH('tr'), TYPE 
    ) AS NVARCHAR(MAX) ) +
    N'</table>' ;

EXEC msdb.dbo.sp_send_dbmail @recipients='danw@Adventure-Works.com',
    @subject = 'Work Order List',
    @body = @tableHTML,
    @body_format = 'HTML' ;

根据我自己的逻辑，我有一个名为Rating的列，设置为'Good'或'Bad'。我想让所有评分为“Bad”的行都有红色背景。我知道如何在HTML中执行此操作，但不知道如何使用此示例中演示的“FOR XML”查询来执行此操作。似乎我必须为某些TD语句添加属性，而不是其他语句。

你不能直接这样做。需要一点点“手工制作”的HTML。这是一种可以使用的方法。

在单独的CTE中选择好的和坏的记录并附加“td”标记。对于不好的人来说，也可以附加Style样式信息。

然后追加“tr”标签并组合（UNION）数据行并使用for xmlpath连接它们。

为了简单起见，我已按列删除了订单，但您可以在CTE中选择它们并稍后对结果进行排序。

注意：我测试了输出HTML并且它有效，但我不是HTML人员所以不要介意HTML标签中是否有任何错误。可以随意更正它。

sp_send_dbmail - 将表格中的行格式化为红色以表示警报
