I’ve disabled row counting using SET NOCOUNT ON but it seems that sqlserver is still counting rows.

USE Northwind
SET  NOCOUNT ON;
SELECT * FROM Products p
SELECT @@ROWCOUNT AS 'RowCount';

the query returns 77 for row count, why?

    SET NOCOUNT ON;

    prevents the rowcount from being returned when you execute your stored procedure. It has no affect on @@rowcount.

    see http://msdn.microsoft.com/en-us/library/ms189837.aspx for specific info

    The @@ROWCOUNT function is updated even when SET NOCOUNT is ON.

    SET NOCOUNT ON prevents the sending of DONE_IN_PROC messages to the client for each statement in a stored procedure. For stored procedures that contain several statements that do not return much actual data, or for procedures that contain Transact-SQL loops, setting SET NOCOUNT to ON can provide a significant performance boost, because network traffic is greatly reduced."
