Basically, you can use DBMail, if that's your preferred method of sending e-mail from within SQL server. Here's another thread that shows you an example and talking about limitation of sending query results via that method.
So, add this to your scheduled job and you should get desired results.
Here's how to control the query output and placement in the e-mail straight from MSDN if you want to use CSV or similar:
[ @attach_query_result_as_file= ]
attach_query_result_as_file Specifies
whether the result set of the query is
returned as an attached file.
attach_query_result_as_file is of type
bit, with a default of 0.
When the value is 0, the query results
are included in the body of the e-mail
message, after the contents of the
@body parameter. When the value is 1,
the results are returned as an
attachment. This parameter is only
applicable if @query is specified.
[ @query_attachment_filename= ]
query_attachment_filename Specifies
the file name to use for the result
set of the query attachment.
query_attachment_filename is of type
nvarchar(255), with a default of NULL.
This parameter is ignored when
attach_query_result is 0. When
attach_query_result is 1 and this
parameter is NULL, Database Mail
creates an arbitrary filename.
[ @query_result_header= ]
query_result_header Specifies whether
the query results include column
headers. The query_result_header value
is of type bit. When the value is 1,
query results contain column headers.
When the value is 0, query results do
not include column headers. This
parameter defaults to 1. This
parameter is only applicable if @query
is specified.
[ @query_result_width = ]
query_result_width Is the line width,
in characters, to use for formatting
the results of the query. The
query_result_width is of type int,
with a default of 256. The value
provided must be between 10 and 32767.
This parameter is only applicable if
@query is specified.
[ @query_result_separator= ]
'query_result_separator' Is the
character used to separate columns in
the query output. The separator is of
type char(1). Defaults to ' ' (space).
If you want to use XML, you just have to make sure your query returns XML. Otherwise, you'd have to write a procedure to format tabular query as XML.
Here's another route using SSIS, but it's more involved, but gives you more control over the output and formatting.
