Optimization: Set Nocount On
From Wiki
When you have a lot of updates and inserts or deletes in a stored procedure it is good to set nocount to on. SQL server can become really chatty when this setting is off; this will waste bandwith and CPU power. If a proc is called 30 times a second and you do 3 DML operations then that will result in 90 n row(s) affected) messages
set nocount on should be the first statement in the proc after the parameters and the AS. Example:
- CREATE PROC Employee
- @Param1 INT
- AS
- SET NOCOUNT ON
- ...rest OF PROC
