How does FB do in this respect? To the best of my knowledge, FB does support serialisable transaction level - I'm 95% sure that it does - will look into this and report back! > > > Functional and Partial indexes > > O > No partial indexes? Get them to put it on their TODO list ;) What, exactly, is a partial index? A functional index is an index on something like ((ColumnX*2)/14)? I think the functional one (is that also an expression index?) is on the way. > BTW, has FB got an equivalent of PG sequences? Yes - "Generators" - easy and simple.
