Question

我有有效的查询：

SELECT TOP (1000) [dashboard_name]
,[dashboard_path]
,[UserName]
,[timestamp]
,(SELECT TOP(1) DATEDIFF(day, timestamp, GETDATE()) FROM [Monitoring].[dbo].[Temporary_logins_log] t WHERE t.dashboard_name = dashboard_name AND t.dashboard_path = dashboard_path AND t.UserName = UserName) AS [Age] 
FROM [Monitoring].[dbo].[Temporary_logins_log] where timestamp = CONVERT(VARCHAR(10), getdate(), 111)

我想使用以下方式通过邮件发送结果：

DECLARE @tableHTML  NVARCHAR(MAX) ;  

SET @tableHTML =  
    N'<H1>Header</H1>' +  
    N'<table border="1">' +  
    N'<tr><th>Report Name</th><th>Report Path</th>' +  
    N'<th>LoginName</th><th>Date</th><th>Age (days)</th></tr>' +  
    CAST ( ( SELECT td = t.dashboard_name, '',  
                    td = t.dashboard_path, '',  
                    td = t.UserName, '',  
                    td = t.timestamp, '',
                    td = (SELECT TOP(1) DATEDIFF(day, l.timestamp, GETDATE()) FROM [Monitoring].[dbo].[Temporary_logins_log] l WHERE t.dashboard_name = l.dashboard_name AND t.dashboard_path = l.dashboard_path AND t.UserName = l.UserName) AS [Age], ''
              FROM [Monitoring].[dbo].[Temporary_logins_log] t where timestamp = CONVERT(VARCHAR(10), getdate(), 111)
              FOR XML PATH('tr'), TYPE   
    ) AS NVARCHAR(MAX) ) + N'</table>' ;  

EXEC msdb.dbo.sp_send_dbmail @recipients='name@work.com',  
    @subject = 'SQL Report',  
    @body = @tableHTML,  
    @body_format = 'HTML' ;

但是我在关键字AS 附近收到语法错误。是否可以使用此代码发送子查询结果，或者我必须重新处理它以使其自身与表联接，而无需使用子查询？

查询中的这一行没有意义：

td = (SELECT TOP(1) DATEDIFF(day, l.timestamp, GETDATE()) 
      FROM [Monitoring].[dbo].[Temporary_logins_log] l 
      WHERE t.dashboard_name = l.dashboard_name AND 
            t.dashboard_path = l.dashboard_path AND
             t.UserName = l.UserName
     ) AS [Age], ''

您是否希望列别名为td或[Age]？我猜是td。如果是这样，请删除as [Age]。
