Subject: Re: [JDBC] Duplicate Columns on Insert
Do you know what INSERT statement JBoss is constructing (sounds
like perhaps it is including the same column twice in the insert)?
Exactly,
Is the
column in question both a CMP field and a CMR field?
Yes
If so, and you
remove the CMP entries for it so it's just a CMR field, does it work?
Yes it does,
But this has several negative implications.
1, A CMR field cannot particpate as the primary key in table B
What is perplexing here is that Hypersonic works fine?

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
