With "make" I can do "make -n" and it just tells me what it would do but

How could I do that with SQL?
I want to write a really complicated (for me) SQL UPDATE statement. I'm sure I
won't get it right the first time. Is there an easy way to not really make the
changes?
I've thought about starting a transaction and then roll it back. That would
undo the changes. But I won't be able to tell what the changes were.
Assuming you are not doing this in a function, you can. Do UPDATE, then
SELECT to see your changes or not and then ROLLBACK.
Thank you for your time,
Perry
