Subject RE: Does derby support still work?
Date Mon, 25 Aug 2008 13:46:34 GMT
FWIW - I ran the V3.3RC3 Test project (same as release) against 
Derby (both embedded and network server versions).  
This checks a LOT of standard functionality, including the 
table creation and data type mappings.

In the table creation side of things, there were no issues in 
creating the test tables (which include every Torque/JDBC 
supported data type.  There were some issues relating to 
Torque/Derby not being able to drop some tables because they 
contained circular foreign key references (part of what the 
test suite check that Torque handles).  This was handled 
manually in running the tests by making sure the DB was 
recreated from scratch each run.

The only functional test that failed was related to Derby not 
allowing expressions in an order by clause where grouping or 
distinct is used. E.g. ORDER BY UPPER(x.y) where x.y is in the
group fails because Derby does not consider UPPER(x.y) are 
part of the group.

This caused the testJoinOrderDistinct test case to fail... but 
everything else worked.

Here's the e-mail outlining the details:
