Well, there's two problems with your program:
1) INSERT INTO .... FETCH ALL is not currently implemented. You would need to
use a loop, and insert one row at a time by value.
2) You can't insert the rows you've just deleted from the base tables. In
your example, the TOTAL cursor would be empty. I think that what you really
want is a temp table.
