Hello;
A couple of years ago I was investigating DB2 and WO. A couple of
people were kind enough to point me in the right direction. I've
got another question. I could be wrong, but suspect that DB2
doesn't support deferred RI checks -- if this is the case, how are
people managing to work around this problem with EOF? Chuck; does
your operations ordering system work for more than just MSSQL?
It works for anything. It is high enough up in EOF to be DB agnostic.
It is just _needed_ for MSSQL. I leave it on when using FrontBase
(which is most of the time).
David Avendasora pointed out a bug in it if you are using self-
referential relationships (entity with a relationship to itself). I
gave him a patch, but I really need to rethink some parts of that
code. It works for most things, but I think there are some more buggy
cases. It also does not (yet) order operations on the same table
which self-referential relationships really need.
No deferred constraints. Sigh. DB2 just dropped a notch in the
respect that I had for it.
