Stored procedures Stored procedures permit one call to a remote database to perform a pre-programmed procedure in a database application environment in which many situations are repetitive. For example, for receiving a fixed set of data, performing the same set of multiple requests against a database is necessary. Processing a single SQL statement for a remote database requires sending two transmissions: one request and one receive. An application might require many SQL statements to complete its work. This could result in many acts of transmission. A stored procedure that encapsulates those many SQL statements would enable the work to be done in one transmission. A stored procedure is a dynamically linked library (DLL) or program that runs on the server and is called by the database engine in response to a call by a client.
