Explaining the Difference Between a Procedure and a Function in PL/SQL

When working with PL/SQL, it is essential to understand the distinction between a procedure and a function.

Focus Keyword: PL/SQL Procedure vs Function

Procedure:

A procedure in PL/SQL is a subprogram that performs a specific task or set of tasks. It is mainly used for executing a sequence of statements and does not return any value. Procedures are commonly used for modularizing code and improving reusability.

Function:

On the other hand, a function in PL/SQL is also a subprogram that performs a specific task. However, the key difference is that a function returns a single value. Functions are useful for calculations and returning results to the calling program.

In summary, while both procedures and functions are subprograms in PL/SQL, the main difference lies in the fact that procedures do not return any value, whereas functions return a single value.
