html - sp_send_dbmail - 将表中的行格式化为红色以发出警报

Question

我在此 MSDN 页面上使用类似于示例 C 的内容: 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' ;

我有一个名为评级的列，根据我自己的逻辑设置为“好”或“差”。我想让所有评级为“差”的行都具有红色背景。我知道如何在 HTML 中执行此操作，但不确定如何使用此示例中演示的“FOR XML”查询来执行此操作。似乎我必须向某些 TD 语句而不是其他语句添加属性。

您不能直接执行此操作。需要一些“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”标签。对于坏的，还要附加样式信息。

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

为简单起见，我删除了按列排序，但您可以在 CTE 中选择它们，稍后再对结果排序。

注意:我已经测试了输出的 HTML，它可以工作，但我不是 HTML 专家，所以如果 HTML 标签中有任何错误，请不要介意。欢迎随时更正。
