Microsoft SQL Server provides the stored procedure
mechanism to simplify the database development process by
grouping Transact-SQL statements into manageable blocks.

Benefits of Stored Procedures

Why should you use stored procedures? Let's take a look at
the key benefits of this technology:
Precompiled execution. SQL Server compiles each stored
procedure once and then reutilizes the execution plan. This
results in tremendous performance boosts when stored
procedures are called repeatedly.
Reduced client/server traffic. If network bandwidth is a
concern in your environment, you'll be happy to learn that
stored procedures can reduce long SQL queries to a single
line that is transmitted over the wire.
Efficient reuse of code and programming abstraction. Stored
procedures can be used by multiple users and client
programs. If you utilize them in a planned manner, you'll
find the development cycle takes less time.
Enhanced security controls. You can grant users permission
to execute a stored procedure independently of underlying
table permissions.
Stored procedures are very similar to user-defined
functions, but there are subtle differences. For more
information, read Comparing Stored Procedures and User-
Defined Functions.
