根据“如果正文内容真发送/假不发送”发送数据库电子邮件

Question

我想根据“如果正文内容真发送/假不发送”发送电子邮件 如果没有返回的东西不发送，则不一定是如果有返回的东西发送。 我的代码基于来自 https://dba.stackexchange.com/questions/83776/need-to-send-a-formatted-html-email-via-database-mail-in-sql-server-2008-r2

的帖子

如果您发现此代码有点混乱，则问题所有者在上述链接中接受为最佳答案。 使用 MS SQL Server 2014

SET @Body = ( SELECT    td = CONVERT(VARCHAR(10), P.Date, 120), '',
                    td = P.ID, '',
                    td = P.ID2, '',
                    td = G.ID, '',
                    td = D.ID,'',
                    td = D.Name,'',
                    td = CASE WHEN G.SubmittedDate IS NULL THEN 'New'
                              ELSE 'Dealer Submitted'
                         END, ''
          FROM      I_CancelledGRN I
                    INNER JOIN TxnGRN G ON G.ID = I.ID
                    INNER JOIN Distributor D ON D.UID = G.DistributorUID
                    INNER JOIN POTxn P ON P.SiteUID = G.POTxn_SiteUID
                                          AND P.UID = G.POTxnUID
          WHERE IsCancelled IS NULL
        FOR   XML RAW('tr'),
              ELEMENTS
        )




SELECT  @Body = @TableHead + ISNULL(@Body, '') + @TableTail

EXEC sp_send_dbmail 
      @profile_name='DatabaseEmailProfile',
      @copy_recipients ='aasc@stackexchange.com',
      @recipients='aa.sc@outlook.com'
      @subject='Query Result',
      @body=@Body ,
      @body_format = 'HTML' ;

这样的东西对你有用吗？

SET @Body = ( SELECT    td = CONVERT(VARCHAR(10), P.Date, 120), '',
                    td = P.ID, '',
                    td = P.ID2, '',
                    td = G.ID, '',
                    td = D.ID,'',
                    td = D.Name,'',
                    td = CASE WHEN G.SubmittedDate IS NULL THEN 'New'
                              ELSE 'Dealer Submitted'
                         END, ''
          FROM      I_CancelledGRN I
                    INNER JOIN TxnGRN G ON G.ID = I.ID
                    INNER JOIN Distributor D ON D.UID = G.DistributorUID
                    INNER JOIN POTxn P ON P.SiteUID = G.POTxn_SiteUID
                                          AND P.UID = G.POTxnUID
          WHERE IsCancelled IS NULL
        FOR   XML RAW('tr'),
              ELEMENTS
        )


IF LEN(@Body) > 0
BEGIN

SELECT  @Body = @TableHead + ISNULL(@Body, '') + @TableTail

EXEC sp_send_dbmail 
      @profile_name='DatabaseEmailProfile',
      @copy_recipients ='aasc@stackexchange.com',
      @recipients='aa.sc@outlook.com'
      @subject='Query Result',
      @body=@Body ,
      @body_format = 'HTML' ;

END

它只是检查天气@Body 是否有任何长度，如果有则只发送邮件。根据您的情况，您可以使用任何其他评估来代替 LEN
