I followed the link and comments on the article, and one of them
http://threads.embarcadero.com/threads/threads.exe/view?commentid=32620
from a Borland ex employee implies that the BDE is a more robust implementation
than what followed it (as Borlands own products depended on it) – its main
disadvantage being tied to DBase and Paradox architecture.
Any other opinions? How many out there use the BDE, or what works best for
them with Firebird (I have heard much good about IBObjects)

I believe that the SQL Links in the BDE have been deprecated

I got a solution for this problem after much experimentation:
I checked carefully the BDE setup as from Delphi 5, and the BDE as installed
by Delphi 2007/XE2. The later install was missing the Firebird/interbase
driver, so I downloaded the ODBC driver (its readily available) and installed
it. However it does not work, so I compared with the older BDE which has the
same version number but is not exactly the same - it has a native Interbase
driver built in (INTRBASE) so I installed the older BDE and hey presto that was
the final missing link.
Under Windows 7 the Setup has to run as Administrator as well.
Maybe under XE2 Professional the native Interbase/Firebird driver is omitted
from the BDE? That may be the case because I see its present in the XE2
Enterprise BDE. Seems a bit scummy and petty to take it out of a component
that hasn’t otherwise been modified for 12 years!
The reason for sticking with BDE is that yes its a bother to set up on the
client PCs but thats a once off pain and OK if you have a good install. The
program uses the TQuery component very widely, which has the nice feature of
being able to do updates as well with specified fields – the effort to change
to other update mechanisms right though the code is more than the bother of
using the BDE.
Personally I rather like the BDE type of operation, simple and reliable and
compares well to ADOQuery and IBQuery. What do others think?

Hi John
At http://www.firebirdsql.org/manual/ufb-cs-appdev.html I read
The Borland Database Engine (BDE)
Borland markets “enterprise versions” of a number of integrated development
tools – Delphi, Kylix, C++Builder, JBuilder and some older products – which can
use the proprietary Borland Database Engine and native SQL Links InterBase
drivers as a “black box” middleware layer to make InterBase and, latterly,
Firebird databases behave like desktop databases. BDE version 5.2 and its
associated InterBase driver, which first shipped with Delphi 6E, supports both
Firebird and InterBase version 6, although it has known bugs affecting the
Dialect 3 date and time data types.
I used the BDE extensively once and would run a long way to avoid it now. I
converted one largish BDE app to FB2.5 +IBObjects. No significant problems. So
much for a grizzle. You may have compelling reasons to hang with the BDE.
Perhaps a replacement from 5.01 to 5.2 would help?
There is a download link here for BDE 5.2.

Subject: [DUG] Firebird V2 BDE Windows 7
I am getting a legacy program that uses both BDE and TIB connections to a
Firebird V2 database working on Windows 7.
Have installed BDE (the old version – V5.01) OK – the trick is to install as
Administrator
Have installed Firebird server and the database.
Can connect to it using EMS SQL Manager and Flamerobin just fine and browse
the tables and run SQL etc. – ie the Database file and server all look fine.
the programs TIBQuery connection also seems to be working OK.
However I cannot connect to it using BDE – it looks like the problem is the
driver. I installed the Firebird/Interbase ODBC driver, but it may be that
the original XP PCs using an Intersolv native INTRBASE driver, for which I
don’t have an install, or an install of the BDE that once included an INTRBASE
driver that I don’t have in my fresh BDE install.
Anyone have suggestions how to get the BDE connection working?
