Describe the difference between a stored procedure and a function in PL/SQL.

```html

In PL/SQL, the main difference between a stored procedure and a function lies in their return types and usage. A stored procedure is a reusable set of PL/SQL statements that can perform multiple operations and may or may not return any value. It is primarily used for generic operations, such as updating tables or executing complex logic.

On the other hand, a function in PL/SQL is a subprogram that must always return a value. Functions are commonly used to compute and return a single value based on input parameters. They are designed for specific calculations or transformations and can be used in SQL queries just like any other expression.

When deciding between using a stored procedure or a function in PL/SQL, it is essential to consider the intended purpose and the need for returning a value. Stored procedures are ideal for handling multiple tasks without the necessity of a return value, while functions are best suited for computations that require a specific output.
