Sql server sql server 2012：如何处理send_dbmail中@query变量的varbinary？

我的目的是通过sql代理作业管理的存储过程来监视cdc进程。我正在查看自上次执行作业以来是否捕获了任何数据。IntervalHours表示自上次批处理运行以来的小时数。以下是用于设置notify/notify决策的代码段：

  declare @FromLSN binary(10)
  declare @ToLSN binary(10)
  declare @BeginTime datetime 
  declare @EndTime datetime 
  declare @hasCurrentChanges int
  declare @SendLowFloorMessage bit

  select @BeginTime = dateadd(hh,-@IntervalHours,getdate())
  SET @EndTime = GETDATE();

  -- Map the time interval to a change data capture query range.
  SET @FromLSN = [myInstance].sys.fn_cdc_map_time_to_lsn('smallest greater
      than or equal', @BeginTime);

  SET @ToLSN =   [myInstance].sys.fn_cdc_map_time_to_lsn('largest less than 
      or equal', @EndTime);

  -- Return the count of the net changes occurring within the query window.
  SELECT @hasCurrentChanges = count(*) FROM
         [myInstance].cdc.fn_cdc_get_net_changes_dbo_CRM_POSTran(@FromLSN, @ToLSN, 
          'all');

--这是决定--

我假设您对sp_send_dbmail有很好的处理能力，只是不知道如何使用varbinary数据类型为@query创建动态TSQL。下面是使用XMLDOM转换数据的一种方法

这里是我的网站的参考，展示了如何为2008 R2发送带有附件的电子邮件

这与2012年几乎相同——在线图书

下面的示例代码采用两个十六进制数，并将它们转换为对cdc.fn\u cdc\u get\u net\u changes的调用

下面是代码段的输出

SELECT * 
FROM  cdc.fn_cdc_get_net_changes_HR_Department
      ('0x5BAA61E4C9B93F3F0682','0x5BAA61E4C9B93F3F0782','all');

谢谢@CraftyDBA！：）我真的很感激你的迅速反应。
