Sending query result as CSV file using DatabaseMail - problem with header

I want to attach as CSV query output, so i wrote something like that:

EXEC msdb.dbo.sp_send_dbmail
@profile_name= 'ReportsSQL',
@recipients= 'mail@gmail.com',
@subject='Report',
@query ='SET NOCOUNT ON;SELECT login, name, city FROM users;SET NOCOUNT ON;',
@attach_query_result_as_file = 1,
@query_attachment_filename = 'output.csv',
@query_result_no_padding = 1,
@append_query_error = 0,
@exclude_query_output = 1,
@query_result_header = 1,
@query_result_separator=';'

Output CSV file seems to be allright with one exception - secodn line:

login;name;city
-----;----;----
alex;Alexander;New York
misza;Misza;Moscow

Select allOpen in new window

How to get ridd of the second line with dashes ???
