sp_send_dbmail-将表中的行格式化为红色以表示警报



我在这个MSDN页面上使用了类似于示例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' ;

我有一个名为Rating的列,根据我自己的逻辑设置为"Good"或"Bad"。我想让所有评级为"坏"的行都有一个红色背景。我知道如何在HTML中实现,但不知道如何使用本例中演示的"FOR XML"查询来实现。似乎我必须为一些TD语句添加一个属性,而不是其他语句。

不能直接执行。需要一点"手工制作"的HTML。这里有一个可以使用的方法。

在单独的CTE中选择好记录和坏记录,并附加"td"标记。对于不好的,还附加样式信息。

然后附加"tr"标记并组合(UNION)数据行,然后使用for xmlpath将它们连接起来。

为了简单起见,我删除了逐列排序,但您可以在CTE中选择它们,稍后对结果进行排序。

注意:我已经测试了输出HTML,它可以工作,但我不是HTML爱好者,所以不要介意HTML标签中是否有任何错误。请随时更正。
