Loop LabelsLike the PL/SQL blocks, loops can also be labeled. The label, an undeclared identifier enclosed by double angle brackets, should appear at the beginning of the LOOP statement, as shown:<>LOOPsequence_of_statementsEND LOOP;Optionally, the label name can also come out at the end of the LOOP statement, as the illustration below shows:<>LOOP...END LOOP my_loop;If you nest labeled loops, you can use the ending label names to improve the readability.

Then, use the label in an EXIT statement, as shown:<>LOOP...LOOP...EXIT outer WHEN ... -- exit both loopsEND LOOP;...END LOOP outer;
