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.
