Query Component Does not Post Until Application is Terminated

Compiler:  Delphi5 Enterprise
BDE Ver:  5.01 or 5.10
Database: Oracle 8.0.5

I wrote a simple program with a TDatabase component, one TQuery, a
TDatasource,
a TDBGrid pointing to the datasource, and a TDBnavigator.  The SQL for the
TQuery
was simply 'Select * from MYTABLE'.
The TQuery's 'Request Live' is set to 'True'.
I run the program, and insert a new record, then post it using the
TDBnavigator.
However, when I run the SQL Explorer and look at MYTABLE the record I posted
does not appear.  The strange thing is that the record will post only after
I exit out
of the program.
Thinking that it may have something to do with the new BDE that came with
Delphi5,
I uninstalled the BDE and reinstalled the BDE version that came with
Delphi4.  I ran
the same program again, and lo and behold , the record(s) I post from my
program
immediately appear in the SQL Explorer.

This leads me to my question:
Is there a step I am missing or a property I forgot to set?  Or may this be
a problem with
the new BDE currently shipping with Delphi5 (and also with BDE version
5.10)?

Thanks in advance for help and guidance in this matter,

PC

Re:Query Component Does not Post Until Application is Terminated


Commit no longer seems to work in BDE 5.1 and Oracle 8.  Having the
same problem.  I don't think it is exiting, but the close of
TDatabase.  I use AutoCommit with TTables and Transaction objects and
neither work.  You are the third to post this problem.  I have posted
the bug and put questions in the BDE new group.  No responses yet.  It
has only been one day.

I put a simple test screen together and it seemed to work fine.  I am
having problems with screens that use a lot of inheritance.  What about
you?

Re:Query Component Does not Post Until Application is Terminated


Thanks for the reply,

So far removing the BDE 5.10 version and reinstalling the BDE
version prior to the upgrade has resolved this problem for me.
I'm currently testing the ADO components, and seriously thinking
about converting my apps to use them, which will enable me to
bypass the BDE altogether.

So far I haven't used screens that uses alot of inheritance, and I
haven't experienced any problems in that area.

Re:Query Component Does not Post Until Application is Terminated


How did you remove 5.10.  I don't see an uninstall.  I ended up just
deleting all the directories and any registry entries.  That workstation
works better, but it is sometimes showing undesired features!

I plan on doing my workstation tomorrow.  ADO isn't an options for me
at this point.

Isn't there an uninstall in the Control Panel Add/Remove Programs?

Re:Query Component Does not Post Until Application is Terminated


I removed the old BDE just the way you (Mr. TMiller) did by deleting the BDE
folder and registry entries.

So far the previous BDE hasn't shown any undesirable effects.  I
believe that if you recompile your program with the old BDE installed, and
the computer you run it on also has the same BDE version, then  it should
not
give you any undesirable effects.

Regards,
Patrick

Join the club!

It seems to be a "BugDE" :-)

I only have a simple data loading program that appends records to another
table.
The changes are commited ONLY AFTER the application ends!

Sorry...

If this is with Oracle download the new update Oracle SQL Link driver from the
Borland website.  This bug is fixed in it.

Nope.  I'm using Paradox 5.10 with Delphi 3.0.

Same problem they were experiencing.

Re:Query Component Does not Post Until Application is Terminated


i'm not sure about this.  Is the SQLPASSTHRU option I saw mentioned in the 5.10 (and
oracle update) have any bearing on me?  This bug makes it VERY difficult to program.
I can't tell half the time if it's me or a bug.

Local share setting is in the bde admin I take it?

I do not think SQLPASSTHROUGH affects pDox users.

Quote

Yes it is.  Check out the configuration tab System->Init.  By default this
setting will be false.  When it is false pDox and dBase write cache the changes
and only post them to the physical DB when the dataset is closed (like when the
application is closed).  This improves performance, but in a multi user
situation no one else can see the changes until the dataset is closed.  This
performance boost isn't as big nowadays as when it was first introduced due to
faster machines and networks.

Thanks much.  I'll check that option.  It might just save me .open .close statements
allover the place.
