By default when you run any statement you will see in the message like no of records affected.
As shown in below figure.
Although, most of the time we do not require such information but still it is overhead.
So to stop such overhead which impact performance just use SET NOCOUNT ON in your stored procedures.
SET NOCOUNT ON ;
SELECT * FROM RequestMaster
When you use SET NOCOUNT ON you will get a simple message
“ Command(s) completed successfully.”
