Subject Supported transaction isolation levels?
Author Thomas Steinmaurer
Hi all,

I hope this isn't that much off-topic here, but I do need some type of
confirmation what SQL-compliant transaction isolation levels are
supported in Firebird. ;-)

Looking through different Firebird related documentations (Helen's book,
IBP pdf set, ...), it seems that Firebird doesn't support the
SQL-compliant transaction isolation level "REPEATABLE READ". Is this

Of course, there is an isolation level called "SNAPSHOT", but are these
equivalent or in particular cases different? I guess there needs to be a
difference, otherwise REPEATABLE READ would have been mentioned.

Thanks for anyone who can share his/her experience.
