Differences between Function and Procedure in PL/SQL

In PL/SQL, the main differences between a function and a procedure lie in their return types and how they are called.

• Return Type: The primary distinction is that a function returns a value to the caller, while a procedure does not return any value.
• Usage: Functions are typically used to perform calculations and return a single value, whereas procedures are used to execute a series of statements without returning any value.
• Calling: Functions are called in SQL expressions to calculate values, while procedures are called as standalone statements or within other procedures or functions.

Understanding the differences between functions and procedures is crucial in PL/SQL development to ensure efficient and effective use of these programming constructs.
