Re: Logminer Question

What's puzzling is the developer is claiming that no ORA- errors were seen, so even with a PK or unique key violation that should throw an error.

Does Oracle actually apply the transaction then roll it back in cases of PK/Unique viloations?

Interesting, I'll test for that

thanks!
