DECLARE @query NVARCHAR(1000);
DECLARE @query_attachment_filename NVARCHAR(520);
SELECT @sub = 'TEST XML ATTACHMENT';
SELECT @msg = 'Please refer to the attached spread sheet for the report.';
SELECT @query = 'exec sp_who2 sa';

EXEC msdb.dbo.sp_send_dbmail
     @profile_name = 'result',
     @recipients = 'thoang@yahoo.com',
     @copy_recipients = 'thoang@yahoo.com',
