Good point, any of my validation checks may be outdated in an update...
stupid of me not to think about that, thanks!

Thanks! :)
I just reinstalled my Operating systems so i haven't looked up the trunk
for
a while, i guess i have to!!! :P
The main idea is to build a form that "autosaves" any changes, so i have
to
explicitly call just rollback uppon cancelation. Is there another reason
to
prefer to call Commit myself?
Yes.
The data in the form may be invalid, in which case the
insert/update/whatever may fail.

Hi guys,
i was under the impression that the “Action” property had a value in
TSQLTransaction component...
correct me if i am wrong but in testing i did and in code (sqldb.pp) i
saw
that it doesn’t matter the value i put in the property, the default
action
when a transaction closes is rollback.
And now the question part
a) am i right?
Yes.
b) is this a todo?
No, it is already done in trunk.
c) is there a timeline?
It is done.
In SQLDB, it is better to call explicitly Commit, Rollback or
RollBackRetaining.
It may require a typecast:
(Q.Transaction as TSQLTransaction).Commit;
Unless you have the transaction object declared somewhere, in which case
you
don't need the typecast.
Michael.
