The benefit of this is that the network traffic is greatly reduced as several Transact-SQL statements contained in the stored procedure are not required to travel through the network individually. Only the name of the stored procedure and its parameters are transmitted over the network.

The stored procedure runs faster than ad hoc Transact-SQL batches, especially when used in repetitive tasks. This is because SQL Server always caches a stored procedure execution plan in an area...
