Hi.
If you are using Oracle 11g you can use the CONTINUE or CONTINUE WHEN.

How to go to end of loop (i.e. next record)�I can think of many ways to do this but is there a definitive best practice?I'm sure there must be articles on this somewhere, so links as well as comments are appreciated.��BEGINfor cur1 in (SELECT bla bla bla)�� �LOOP��� � If something_I_dont_like then skip to next record in cur1;��� � Lots and lots of code goes here.���� �END �LOOP;END;�Some options:1) You could set up a label and use a goto.2) You could set up an inner block and use RAISE to break out:�3) You could do something like :�BEGINfor cur1 in (SELECT bla bla bla)�� �LOOP�� � � � <<process_this_record>>�� � � � FOR c2 IN (SELECT * FROM DUAL) -- creates an exitable one-time loop�� � � � LOOP��� � � � � �If something then��� � � � � � � � � exit process_this_record;��� � � � � � �Lots and lots of code goes here.���� � � � END LOOP process_this_record;�� �END �LOOP;END;�4) You could just nest IF statements like:�BEGINfor cur1 in (SELECT bl
a bla bla)�� �LOOP�� � � � IF keep_processing_this_transaction THEN�� � � � BEGIN�� � � � � � ��Lots and lots of code goes here.�� � � � END IF;�� �END �LOOP;END;�So, what is the best way?�Regards,Mike
