It is not the driver. Really, it is not.
It is the SQL that EOF is generating. It is generating the WRONG
SQL. That is the problem that you need to solve. The error you are
seeing is just a symptom of the problem. You need to fix the problem.
Right now I'm just looking for any more ideas as to where look for a
possible cause on this. The EOModel files seem to be fine
I'd be pretty suspicious that they are not. Are you using any data
types in this table that you don't use elsewhere? CLOBs? BLOBs?
I can't find anythign out of the ordinary I'm not sure where else to
look or if there are any parameters that can be changed to alter how
locking is handled.
It is either in the model definition or in your code. Or, I suppose,
both. You may be hitting a bug in EOF, but it is your model or code
that is exposing it.

No, you don't. It is bad, but not that bad. ;-)
