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: 10.5.1.1, 10.6.0.0
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).
