Use the Merge-OUTPUT function to dump results with msdb.dbo.sp_send_dbmail

问题

I frequently use the msdb.dbo.sp_send_dbmail tool in SQL Server for automated reports and such but I've never really used it to for an update/delete type statement in the @query section.

Is it possible to do so? When I run this query, it gives 0 results and doesn't execute the actual Merge and Delete function within the @query section.

I'm running a test scenario where I know there should be results, and that it should be deleted but no dice. Any advice appreciated as I may be missing something as I'm thinking it might be an order issue. But I thought putting it within the @query should execute as should be. Query style below:

DECLARE @results NVARCHAR(1000)

Select @results = N'
MERGE Table1 A
USING Table2 B
ON A.ID = B.ID and A.recorddate = B.recorddate
WHEN NOT MATCHED BY SOURCE THEN delete
OUTPUT
$action,
deleted.*;';

Begin
EXEC msdb.dbo.sp_send_dbmail 
    @profile_name = 'Test',
    @recipients= 'test@test.com',
    @query = @results,
    @from_address = 'test@test.com', 
    @subject ='Delete Row',
    @attach_query_result_as_file = 1, 
    @query_attachment_filename = 'Merge Test',
    @query_result_separator='$',
    @query_result_width =32767,
    @query_result_no_padding=1,   
    @body = 'Results',
    @body_format = 'HTML' ;  
End

The result of the query should execute and delete the unneeded row and then output the results which I'm hoping could be exported to the .CSV and e-mailed to me so I can review what was deleted.

EDIT: Got it! Just going to use a temporary table to store results and dump that into a .csv and drop it at the end

select * into #temptable from TableA where 0=1;
MERGE Table1 A
USING Table2 B
ON A.ID = B.ID and A.recorddate = B.recorddate
WHEN NOT MATCHED BY SOURCE THEN delete
OUTPUT
$action,
deleted.* INTO #temptable;
drop table #temptable
