Tried new version of perfino (4.0), but didn't find a way to connect it to MySQL.
Is support of MySQL dropped in new version?
Official MySql support has indeed been dropped in 4.0, only the built-in database is supported from this point on.

I have an application which loads some external data based on gremlin.
I want to use it to load the data into a Neo4j database.
I saw that there was partial support for gremlin in previous versions but couldn't find any solution for latest version.
I'll be happy to hear if it is still possible and how can it be done.
At this point, TinkerPop expects to support 3.4.11 in its future 3.5.0 release (here) which is yet several months away. For TinkerPop to support 4.0 it would need a fresh release of the neo4j-tinkerpop-api-impl to be released with that version. It seems an issue has been created for that here.
I understand that was possible in previous versions, and I also understand that version 4.0.0 is a total redesign towards a server-first approach, but nowhere in the documentation it is said whether embedded mode is supported.
4.0.0.RELEASE is server only. Embedded support will be available in a future release.
I am trying to install informix dynamic server version 7.
IBM site provide links to "Informix" version 11 Plus.
Anyone knows how can I reach the installation files?
Informix 7.31 (last in 7.x family) support ended in 2009. So you won't find the installation files anywhere. And you may have troubles installing such an old product on today's operating systems.
There was no "free" version of Informix 7 as there is today for current versions.
If you actually "own" the product you may try to contact IBM and explain why you need it.
It would also be nice to know why you need it? Do you need to restore some old backup?
Regards.
I'm wondering if there's a site where I can download older versions of the Advantage Database Server and the Advantage Database Architect.
On this site only the newest version is avaialable.
Unfortunately, the new versions are often unstable or bring in new bugs, and so you are forced to downgrade to an older version.
Latest example: I just upgraded from Data Architect 10.10.0.6 to 10.10.0.17 and it wasn't possible anymore to create or modify triggers.

I have an older application (written in Delphi 6) that has to be ported to Delphi 2006 (update 2). The application used to connect to an Interbase 6.x database using DBExpress, but the new version needs to connect to a Firebird 2.x Superserver.
Porting went OK, no real problems. But now, when I try to connect to the new Firebird server from the ported app, I get the following error:
Database error
Database Server Error: no current record for fetch operation
Running the same application compiled with Delphi 6, talking to the same Firebird server runs fine. The changes needed to compile the app in Delphi 2006 weren't related to the database code - all local library stuff. The application uses TSQLDataset en datasetproviders and clientdatasets.
Anybody has any idea how or why? Any changes to DBExpress that might cause this behaviour?
Thanks.
I don't think Delphi 2006 supports Firebird natively. Think you need to install FIBPlus
Heres a list of what is supported in Delphi 2006:
Old driver New driver Database and Version
dbexpinf.dll dbxinf30.dll Interbase 7.5
dbexpora.dll dbxora30.dll Oracle 10g
dbexpdb2.dll dbxdb230.dll db2 UDB 8.x
dbexpmss.dll dbxmss30.dll MSSQL 2000
dbexpmys.dll dbxmys30.dll MySQL 4.0.24
dbexpasa.dll dbxasa30.dll Adaptive Sybase Anywhere 9
dbexpase.dll dbxase30.dll Sybase 12.5
dbexpinf.dll dbxinf30.dll Informix 9.x
Extracted from Here
Until Delphi 2010, the built in DBExpress drivers officially never supported FireBird.
In practice, a lot of combinations never worked at all.
Either:
go for a DBExpress driver officially supporting FireBird (search google),
or move to another database middle layer (FIBPlus that James suggests is really good).

First of all, retry the same steps from a new, 1-form app (put SQLConnection, SQLQuery etc etc), fill with the SQL you want and try to connect.
I believe there's some connection parameter that changed between versions, since I've used D2006 DBexpress to access Firebird 2.x with success. But the application were not ported, but new projects.
