Re: types used for JDBC BLOB and CLOB?



Marc,

The answer is it depends, but if they intend to use the jdbc BLOB/CLOB
interface it is server side LargeObjects, not bytea.  However you can
use bytea, but then you need to use the get/setXXXStream() interfaces.

Thanks,
--Barry

'k, I believe what the client is wanting to know is what the storage
type would be on the backend, that the would BLOB/CLOB map to ... bytea?
