With "make" I can do "make -n" and it just tells me what it would do but doesn't actually do anything. 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. Thank you for your time, Perry
