Explaining the Difference Between a Function and a Procedure in PL/SQL
In PL/SQL, a function and a procedure are both blocks of code that can be stored and executed within a database. The key difference between them lies in their return type and usage.
Function in PL/SQL
- Focus Keyword: Function
- A function is a named PL/SQL block that accepts input parameters, performs a specific task, and returns a single value.
- Functions are designed to compute and return a value to the calling environment.
- Functions can be used in SQL queries and expressions to manipulate data or perform calculations.
Procedure in PL/SQL
- Focus Keyword: Procedure
- A procedure is a set of PL/SQL statements that can perform a specific task or set of tasks.
- Procedures can accept input parameters, perform operations, and may or may not return values.
- Procedures are more focused on performing an action rather than returning a value.
While both functions and procedures are integral parts of PL/SQL programming, understanding their distinctions is crucial for designing efficient and effective database solutions.
