Hi Owen,

As Shaun said in another post, you don't use the EO_PRIMARY_KEY table, you use sequences. EOModeler will create them and even try to check the highest current pk value and roll the sequence up to that number.

I had forgotten to mention the stored procedure parameter issue (mentioned in a different post). EOF seems to send the parameters in alphabetical order, so I just got into the habit of naming them (in EOModeler, not in the database) things like "a_firstName" and "b_startDate" or whatever.

Regards,
Mark

Hello Owen,

Over the years I've used much more Oracle than any other db with WO, and I can't think of any gotchas. Primary key support is handled via sequences, which EOModeler will create and even initialize properly for you.

Could you please explain that a bit further ? Do you mean I still don't need the EO_PRIMARY_KEY table ? I just set the primary key in orcale and in the model and they sort themselves out so its always up to date ?



Stored procedures and functions work. No extra framework is required.

I don't have any experience migrating OpenBase over. SQL*Loader is the tool usually used to populate data from flat files. However, there was a post in this group recently about a utility I've never tried that is supposed to move data to and from databases, using text as the intermediate form:

/System/Library/WebObjects/JavaApplications/javaeoutil.woa/ javaeoutil

Good luck!

We were going to try the database transfer functionality of SQL4X Manager ( http://www.dbsuite.de/? action=product&actionid=sql4xmanagerj ) which supposedly not only does data, but also tables/whole schemas as well between a different database types. I'll keep the list updated on how that goes.
But if that fails, I will look into the Util you have suggested.
