Re: Avoid transaction abot if/when constraint violated

Ya, I don't mind that it eventually fails (why have constraints otherwise), but I'd like to see all the constraint
violationsfor the set of records. 

I actually have something working.  I'm coding in perl/DBI, and I just "rollback" after each constraint violation and
keepgoing.  Nothing from the entire stream is committed until/unless they're all clean. 

Thanks

Only if it is a foreign key issue in which case you can defer the check.

If it is a single transaction, and you insert a bad record the whole
transaction fails.
