stored procedure

stored procedure

In a database management system (DBMS), it is an SQL program that is stored in the database which is executed by calling it directly from the client or from a database trigger. When the SQL procedure is stored in the database, it does not have to be replicated in each client. This saves programming effort especially when different client user interfaces and development systems are used. Triggers and stored procedures are built into DBMSs used in client/server environments.

(database)

stored procedure - A subroutine stored in a database and executed by the database management system. The subroutine may be written in the same language in which the database is queried and may be precompiled to improve performance. Typically a stored procedure encapsulates some business process. Performing this on the database server avoids the network overhead of transferring input data to the client for processing. This would be particularly significant if processing lots of data and returning a small result set like a total or maximum. Stored procedures also provide consistent implementation of the business logic to clients written in different languages and running in different environments. Some financial systems allow databases access through stored procedures alone, this restricts actions on the data to a small number of auditable queries. Sybase SQL Server (Adaptive Server Enterprise) was the first commercially successful RDBMS to support stored procedures.
