If you are running a stored procedure and it is not returning this information then when the procedure was written the SET NOCOUNT ON flag was set. This tells the server to not return this information back to the client.
If you are running a standard query in the Query Analyzer or Management Studio and you aren’t getting the information back, it’s because the SET NOCOUNT ON flag has been set, either on your client as a default, or on the server as a default. You can change this by putting SET NOCOUNT OFF in your query above the statement that you want to see the rowcount for.
You can also request after running your query the value of the @@ROWCOUNT variable and return this information.
SET Column = ‘YourValue’
WHERE AnotherColumn = 3
