Thanks for that
The the phrase "nested context" helped me find this page which explained it
well.
http://cayenne.apache.org/doc/nested-datacontexts.html
That gives me more options to think about.

Yes, you should be creating separate contexts for this purpose. If

Hi!
Thank you Andrus and Andrey. I changed the mapping for the columns of
datatype "text" from VARCHAR to CLOB (max length 32000) in Cayenne
Modeler. Everything is working fine now for MS SQL server.
But I also run the applicaion with embedded Derby, where I use VARCHAR
(32000) in the sql

Correction: Test #2 and #3 fail, not #1 and #2. :) Details details!

I've looked at the code a bit. Turns out there're some
UNSUPPORTED_DISTINCT_TYPES in SelectTranslator class. Probably if "text"
type will be added there, this would let go the exceptions. I'll advice to
open a JIRA issue about it.
By now you could try use SQLTemplate. It will not generate any "dist

Hi!
We are using Cayenne with Microsoft SQL Server. We get a
com.microsoft.sqlserver.jdbc.SQLServerException: "The text data type
cannot be selected as DISTINCT because it is not comparable."
The problem is that the following query is not allowed in MS SQL Server:
SELECT DISTINCT column FR
