EXIT WHEN statement exits the loop or block marked by the given label. If the label is not specified, EXIT leaves the innermost loop.

If a boolean expression is specified, and it evaluates to true then EXIT statement is executed, otherwise it is ignored and the execution continues from the statement following EXIT.

Syntax:

EXIT [label] [WHEN boolean_expression];

Example:

WHILE count > 0 LOOP
  count := count - 1;
  EXIT WHEN count = 0;
END LOOP;

<<lbl>>
WHILE 1=1 LOOP
  <<lbl1>>
  WHILE 1=1 LOOP
    EXIT lbl;
  END LOOP;
END LOOP;
