PL SQL Statements Oracle PLSQL Tutorial

The EXIT and EXIT WHEN statements enable you to escape out of the control of a loop.
The format of the EXIT loop is

EXIT;
To terminate a loop, simply follow your condition with the EXIT statement.
This is common when using IF statements.
The Syntax for the EXIT WHEN Loop:

The EXIT WHEN statement enables you to specify the condition required to exit the execution of the loop.
In this case, no IF statement is required.
