Re: ResultSet.updateString against DB2 giving "Column not updatable"

I just talked to an IBM support rep. DB2 supports updatable cursors,
and the universal driver supports updatable result sets, but somehow
the two don't get along:

"Updatable scrollable cursor is supported against z/OS V7, however,
only JDBC 1 styled positioned update is supported, not the JDBC 2
styled updates via the updateXXX methods. This is because extended
describe is not supported on z/OS V7 which is needed for the driver to
retrieve the table name in order to build the update statement
internally."

(This page says the universal driver supports updatable result sets.)

Positioned updates look rather strange, so I think I'll just go back to
a plain SELECT and UPDATE.

Thanks for your input.
