[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5659) Problem using Hibernate3.6.0.Final with CLOB field in Oracle.

]
Steve Ebersole commented on HHH-5659:
-------------------------------------
Followup on my previous comment in regards to Oracle driver... Maybe we just need to
allow the Dialects to tell us when to use stream binding for LOBs. Here specifically the
situation is more like "use streams for binding if the LOB instance is not an Oracle
specific class". So maybe we need to pass the LOB instance for maximum flexibility?
This should be the default behavior if no {{use_streams_for_binary}} is specified.
This is sort of the opposite situation from HHH-4617.
