Question

I try to create a hibernate mapping for an oracle database. The datebase is pretty old from before oracle 8 but is now on 10. Hibernate reverse engineering balks at a long raw column. This datatype is deprecated and should be converted to blob.

But this is not my database. If the customer refuses to convert how would a hibernate mapping look like ?

Answer 1

Try mapping it to byte[].

If you get java.sql.SQLException: Stream has already been closed, then try setting useFetchSizeWithLongColumn = true in the connection properties for the OJDBC driver. See the OracleDriver API
