Subject [jira] Created: (DERBY-4278) Batch inserts with Clobs fails with the embedded driver

Batch inserts with Clobs fails with the embedded driver

                 Key: DERBY-4278
                 URL: https://issues.apache.org/jira/browse/DERBY-4278
             Project: Derby
          Issue Type: Bug
          Components: JDBC
    Affects Versions:,
            Reporter: Kristian Waagan
            Assignee: Kristian Waagan

Batch inserts with Clobs fail because Derby is unable to determine if it should write the
Clob stream header formats using the old 10.4 style format or the new 10.5 format.
More specifically, the access mode (soft upgrade or not) hasn't been set specifically by Derby
before the stream header has to be generated, and there isn't enough context to determine
the mode at generation time.

Bug was reported on derby-user: http://www.nabble.com/Hibernate-%2B-Derby---Unable-to-determine-stream-header-for-hibernate-type-%27text%27-td24099674.html

The bug was reported for Derby used with Hibernate. Possible workarounds are to use the client
driver or to avoid using batched inserts with Clobs (i.e. don't use batched inserts, which
may degrade performance, or use a different data type).
