Hi,
I need a little documentation on CLOB too.
To start, does someone can tell me which java type i have to use (to map)
with a jdbc-type CLOB ?
java.sql.Clob? as the OJB types mapping board shows it. but java.sql.Clob is
only an interface. What object to create so ? ( is there a Clob
implementation ?)
String (or StringBuffer)? does OJB always load all the data on queries !?
oups !
Byte[] ? as BLOB. I need some special character, only found in UNICODE.
byte[] means that content is in "bad" ASCII for me.
any other type ?
you are right, currently the CLOB/BLOB support isn't very sophisticated
(BLOB columns mapped to byte[], CLOB mapped to String - see
JdbcTypesHelper class).
Currently we think about to introduce JdbcType classes which handle the
Clob/Blob interfaces instead of the materialized String/byte[] objects.
Any suggestions are welcome.

Armin
Thanks for any ligtht.

Hi Vamsi,
sorry for the late reply.
I added an JIRA issue (maybe someone can spend time to adapt this
section).

Hello all,
In our application we use OJBs extensively. However, we have a CLOB
field
that needs to be populated within the application. I was trying to find
documentation about OJB's support for *LOB objects at this link:
http://db.apache.org/ojb/docu/howtos/howto-use-lobs.html
However, all I could find was this:
Strategy 1: Using streams for LOB I/O
########## to be written #########
Strategy 2: Embedding OJB content in Java objects
########## to be written #########
Querying CLOB content
########## to be written #########
Is there any documentation out there that explains these concepts? Any
help is greatly appreciated. Thanks.
