Yes, It is possible to label a loop similar to a PL/SQL block. Loop labels are undeclared identifiers enclosed within the double angle brackets. This helps in better readability in case of nested loops. In addition, this helps in using the EXIT statement with the loop label in the nested loops. Label of a loop should appear before the LOOP statement, as shown in the following code snippet:
«first»
LOOP
-----
«second»
LOOP
-------
EXIT second WHEN ------
END LOOP second;
END LOOP first;
