Hello,

I'd like to know if Firebird supports 2 levels of transactions.

To be clear:
I would like to open a main transaction I will be able at any time to commit or rollback. That exists for sure. But I also would like inside that transaction, to open other ones I could commit or rollback as well.
The objective is to implement a single undo function which was not planned before. Another possibility I have been told, but I don't know for Firebird, it to set a serie of milestones you can at anytime in the main transaction rollback to one of these.

Thanks for your support,


Emmanuel Voet
