A stored procedure is a precompiled collection of one or more SQL statements or procedural logic, stored in a database, and assigned a name. It can be called and executed multiple times by referencing its name. Stored procedures are used for code modularity, improved performance, and security in database management systems. They are particularly common in SQL-based databases like MySQL, Oracle, and Microsoft SQL Server.

A stored procedure is a set of Structured Query Language (SQL) statements with an assigned name, which are stored in a relational database management system (RDBMS) as a group, so it can be reused and shared by multiple programs.

A stored procedure is a subroutine that is accessible to programs that use a relational database management system (RDBMS). It is also referred to as proc, storp, sproc, StoPro, StoredProc, StoreProc, span, or SP. These processes are kept in the data dictionary of the database.
