Zeoslib revision 261 is not working with Firebird 2.1 Beta 1

Hello,

All my projects were working good with Zeoslib rev 261 and Firebird 2.01 until I test them with Firebird 2.1 Beta 1. Now nothing more works. Is this happening with anybody else? A simple 'SELECT' doesn´t work anymore when I give the 'Open' command in 'ZQuery', for example.

Ups... if they not change the API it should be work or maybe the check of the protocol 2.0 that limit this?? or something else?

Hello,

Yes, perhaps there is some problem on version checking. I traced the error but I uninstalled 'Firebird 2.1 Beta 1' so I can't reproduce it now. But the error was been raising at 'ZAbstractRODataset' if I'm not wrong, on 'GetFieldData' method. I think the solution to this isn't that difficult but I don't know Zeos internals enough to do it myself.

Hello,

I was afraid Zeos was dead. I think Firebird is used by many people here but no word from Zeos developers about this incompatiblity. Maybe this is because Firebird 2.1 is still in beta stage but I used to use Firebird beta with Zeos with success. No one testing this combination around?

Thanks for any answer from Zeos developers.

Hum, beta release.

Zeos is NOT dead, when firebird came out with a stable release, all things should work. Think that if one developer start to build the compatibility layer (ZPlain, mostly), before the final release comes out, firebird may change 101%. So, this developer is working for almost nobody and for nothing.

Firebird is a great DB, wide spreaded and with a long road ahead. This actual version (2.0) should be merged with firebird vulcan (a fork) at version 3. So, expect many new things to come and many unsuported features

Hello gto,

Thanks for your answer. I use Firebird version 2.01 and it works great with Zeos. Firebird 2.1 has some improvements as you know and I would like to test it but that version doesn't work with Zeos yet. I'll wait for its final release and the respective Zeos compatible layer.

gto,

Do you really think there's a possibility Firebird interfaces will still change before the next release? If not, it would be nice when somebody volunteers to write the new plaindriver unit(s).

mdaems, there's nothing clear until now. Vulcan interface is almost the same of Firebird, but they plan to include new features. I think the best thing is to wait a bit to, at least, an RC release.

Well, I've read the changelog and this release really improves firebird. I've became exited too =D

Here's the changelog:
http://www.firebirdsql.org/devel/doc/rl ... tes21.html

Beside many bugfixes and internal improvements, there are the best new features IMHO:

- database level triggers
- temporary tables
- standard implementation of common tables queries
- UPDATE OR INSERT sql clause
- lots of new internal functions
- unicode collations
- port for w2003-64bit
- database motinoring via system tables
- context (server) information via SQL
