PL/SQL Best Practices [17][Iterative Processing]-Unstructured Exits

Avoid Unstructured Exits from Loops
Do not EXIT or RETURN out of a FOR loop.
    * A FOR loop should only be used when you want to execute the body a fixed number of times.
    * Stay for the duration or use a different loop construct.
    * Note: If an exception is raised and the loop stops, that is a legitimate “early termination.”
Do not use the EXIT syntax in a WHILE loop.
    * The loop should be terminated only when the condition in the boundary evaluates to FALSE.
