I know, it's a mess... I have a persistence framework that supports DB2, Oracle, MySQL, SQLServer and Interbase and it's a nightmare whenever you try to do anything related to catalogs... And planning to integrate PostgreSQL as well... In case you wanna try to implement that stuff differently by calling the ODBC function, have a look at : http://msdn.microsoft.com/en-us/library/ms711831%28VS.85%29.aspx Caution: since you're in Linux, I'd also check iODBC (or whatever you use) for the same API... just in case they would differ (most likely!). This might be a simpler way to accomplish what you need... For Oracle, you might wanna query against the DICTIONARY view to get the same information... Hope this helps. ----------------- Benoit St-Jean Yahoo! Messenger: bstjean Blog: lamneth.wordpress.com A standpoint is an intellectual horizon of radius zero.

It might be helpful. Something similar works for the columns, but getting it to work with a where clause seems to be needlessly fragile. I have code that generates SQL that works just about anywhere, but not with the SQL server information schema. Given MS' involvement, I can't help but think that they might be using a different query engine or something equally stupid. I have also seen documention suggesting that this will not work with Oracle, which is also on my list. Still, this might provide a nice shortcut to the ODBC schema functions.

That is very interesting. Where there is immediate need, 5.x is installed. Thinking about this some more, the mix of clients and servers is more like: Clients: windows, linux Servers: SQL server on Windows MySQL on Windows and Linux .mdb file (mostly migrated to MySQL) Is there a similar schema trick on SQL server? However, I just gave myself query access to the MySQL schema, and would not have such control over the SQL server. It might pay for me to write the code to read the schema via ODBC functions.

Which version of MySQL? Since version 4.1, there's all you need in the "INFORMATION_SCHEMA" database, in the "TABLES" table. But because of some bug in 4.1, query against that database sometimes caused the server to crash. I'd recommend that method only for 5.x and upwards. ----------------- Benoit St-Jean Yahoo!

Hi Bill! Which is the combination of your RDBMS / OS ? Regards from the ESUG :) Mariano

Hello Bill,

2009/8/31 Schwab,Wilhelm K <bschwab@anest.ufl.edu>:

Hello all,

...

Is there anything available for Pharo that gives

schema information about a database?

Doesn't SqueakDBX do that?

Regards,

Esteban A. Maringolo
