Question : getting the total number of rows return added to my dataset using group by

I'm grouping on a table and I need to get the number of rows returned.  What's the best way to get a summary total of the records that have met my Group by/having criteria?  Do I need to write the records to a temp dataset after they have been group by/having processed, then loop through the temp dataset and count the records?  Is there a better way of doing this.  I need to get a summary total of the # of records my "group by/having" clause has created.  I want to print this total on my report  that's reading the dataset. But I don't want to do it in the report.

Answer : getting the total number of rows return added to my dataset using group by

After running the query, you can do this:

Select count (*) as "row count" from (select ) as t

For some reason, the final table alias "as t" is required.
or
select @@rowcount

If you need to use the value later, you can put it in a variable:

set @rows = @@rowcount

also;
Refer to @@ROWCOUNT in SQL Server Books Online. If you are using ADO in your
application, then you can use the recordset's RecordCount property to get
the value at the client side.
