Benefits of SQL Server Stored Procedures

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 we 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.

Structure

              Stored procedures are extremely similar to the constructs seen in other programming languages. They accept data in the form of input parameters that are specified at execution time. These input parameters (if implemented) are utilized in the execution of a series of statements that produce some result. This result is returned to the calling environment through the use of a recordset, output parameters and a return code. That may sound like a mouthful, but you'll find that stored procedures are actually quite simple.
