SELECT goo, foo, boo
FROM YourTable

-- This will give you the number of rows returned in the previous DML query.
SELECT @@ROWCOUNT

So if you want to return that value, you can always stick it into a variable, and at the end of your SP do a SELECT @your_variable, or add it as a column, or whatever.

SELECT COUNT (fieldname) as Field1

from tablename

or if you want to count distinct rows:

SELECT COUNT (DISTINCT fieldname) as Field1

from tablename

@@TOTAL_READ:  The number of disk reads, not cache reads, by SQL Server since SQL Server was last started.
http://msdn.microsoft.com/en-us/library/ms187917.aspx

It is NOT the same as the number of rows returned in a SQL statement.

You give up too quickly -
select t1.name, t2.cnt as getnumbersofrows from
(select name from tbusers) as t1,
(select count(name) cnt
 from tbusers) as t2
;

yeah, what a rush. but, lets continue, i don't want to perform another select to get the count, is there anyway to do while selecting. i have something like this:


select top 100 t1.* from (select t1.name, getnumbersofrows from tb_users where ......) as t1 where .......

i have one query inside another, so i can't use the @@ROWCOUNT since it will give me 100 rows after i perform this query above, and i want to get the query inside the query, i don't know if i was clear with my writing.

The only other way I can see doing that is to create a user-defined function, getnumbersofrows, to get the total count.
