I'm using transactions, with a delete followed by an insert.
If the delete affects 0 rows, there is nothing to do.
Do I need to rollback the transaction to abandon it, or is everything
the way it should after a delete that affected 0 rows?
Thanks!

by a unique scan of the D
index. Adding nonsense criteria such as ... and D.UID 0 doesn't
make things better.
The D table is very wide, so a lot of I/O is wasted by doing a full
table scan.
Thanks!
