Hi again,
I began to modify some H2 code in order to make my use case work. The
attached file is a patch file for org.h2.expression.SequenceValue. It seems
to solve my problem fine but I don't know enough the architecture of the H2
engine to be sure it won't fail in some other situations. I ran "build test"
and I got the same results with and without this patch...
Do you think this is safe ?
Regards
