What is the Difference Between a PL/SQL Function and a Stored Procedure in Oracle?

In Oracle, the main difference between a PL/SQL function and a stored procedure lies in their return types and invocation methods.

PL/SQL Function:

A PL/SQL function is a subprogram that returns a single value. It must return a value using the RETURN statement and can be called from SQL statements or other PL/SQL code.

Stored Procedure:

A stored procedure is a subprogram that performs a specific task or set of tasks. It may not return a value directly but can have OUT parameters to return values. Stored procedures are called explicitly using the CALL statement or from other PL/SQL code.

Therefore, the focus keyword "PL/SQL function and stored procedure difference" is critical to understanding the distinction between the two types of subprograms in Oracle.
