What is a Stored Procedure?
A stored procedure is a set of commands or instructions stored in a database. It bundles together multiple commands into one unit and typically does not return a value.
In Simple Terms
A stored procedure is a collection of commands saved in a database that performs a series of actions without returning a result.
Detailed Explanation
- Basic DefinitionA stored procedure is a pre-defined set of instructions stored in a database to perform specific tasks. It is similar to a function in programming but differs in that it usually does not return a value. Stored procedures are commonly used in database management.
- Comparison with ProgrammingIn programming, a function (or “function”) is a component that takes input, performs operations, and returns a result. A stored procedure is like a function but without the return value. It is a way to bundle multiple commands into a single procedure for execution.
- Usage in DatabasesIn databases, a stored procedure can execute tasks like inserting, updating, or deleting data. By using stored procedures, you can encapsulate these tasks into a single procedure that can be called when needed.
- Difference from Stored FunctionA stored function is another term used in databases, and it differs from a stored procedure in that it returns a value. A stored function performs operations and provides a result, while a stored procedure typically performs actions without returning a value.
In Summary
When you come across the term “stored procedure,” think of it as a “set of instructions in a database that does not return a value.”
