After my limited reading about it, and If I understand it correctly, I do not believe that Duff’s device can be simulated in PL/SQL using CASE because there is no “break” in PL/SQL as there is in C. Moreover, unlike C, CASE breaks automatically at the end of a positive WHEN condition block (continues after the END CASE).

Now, there is this new feature in 11g, CONTINUE, but I do not see that it will make any difference in this case.
