Explain the difference between a function and a procedure in PL/SQL

In PL/SQL, a function is a named PL/SQL block that can accept input parameters and return a value. It must return a single value and can be called from SQL statements or other PL/SQL code.

On the other hand, a procedure is a named PL/SQL block that can also accept input parameters but does not return any value. It is mainly used to perform a series of actions or operations without returning a value.

The key difference between a function and a procedure lies in their return values, where a function returns a value while a procedure does not.
