In Stored Procedure in SQL: Benefits: A collection of SQL statements is referred to as a stored procedure in SQL and is kept together in a database. It can execute one or more DML operations on the database and return value, if any, depending on the statements in the procedure and the arguments you pass. As a result, it enables reuse by allowing you to pass the same statements more than once. In SQL Server, stored procedures programmed statements to perform actions in the database and provide a status value to a calling procedure or batch. Stored procedures can accept input parameters and return multiple values of output parameters. Except when a read-only (resource database) is utilized, user-defined procedures can be created in user-defined databases or in all system databases. They are created using Microsoft’s T-SQL or
Transact-SQL. There are two sorts of temporary procedures: local and global, both of which are kept in temped. While global procedures are visible to any user once they are generated, local procedures are only available to the user connection that is active at the time. System procedures are physically
kept in an internal database that comes with SQL Server. Physically, system procedures are kept in a hidden resource database that comes with SQL Server. They can be found in a user-defined
database as well as each system’s SYS schema.
Stored processes offer a number of significant advantages, including:
1. Reusable:
As previously noted, calling stored procedures allows many users and programmers to use and reuse them.
2. Simple to modify:
By using the ALTER TABLE command, you can easily change the statements in a stored procedure whenever you need to.
3. Security:
By preventing users from directly accessing the table, stored procedures let you improve the security of an application or database.
4. Low network traffic:
The server merely transmits the procedure name, lowering network bandwidth, rather than the entire query.
5. Better Performance:
Performance is improved since a plan for the stored procedure is established on the first use and stored in the buffer pool for speedy execution the next time.
It is important to understand and learn stored procedures because it offers several advantages that are needed for database management. It is merely the basic idea of a large umbrella, though
