Hi ,
 i have a java class persisting a large string(>4k) into a DB table into a CLOB field.
if the string is less in siz(<4k) im not any facing problems, its working fine.

i read somewhere to use the type="text" in the hbm file so kept that which gave a exception for batching not support for streams. so made the batch size to 0. which is giving the exception:

Caused by: java.sql.SQLException: ORA-01460: unimplemented or unreasonable conversion requested

Could the split you string into two with substring, then store it in the database, then concat them back together again.

thanks for a quick reply guyz..
@franckpachot sql generated by hibernate:

Hibernate: select CCAD_ERROR_SEQ.nextval from dual
Hibernate: insert into CCAD_ERRORS (REQUEST_ID, ERROR_DATE, ERROR_CODE, ERROR_TEXT, REQUEST_XML, ERROR_ID) values (?, ?, ?, ?, ?, ?)
- SQL Error: 1460, SQLState: 72000

@Thomas4019
that can be done thomas it like a long way around im trying for a simple and quick fix...
my doubt id that oracle will allow to store large data(like upto GBs) into CLOBs but y is it not letting the
String (which is very small around 5-10k) to go into a CLOB?? any options to set..?? or do we need to change the string to clob object before persisting it into DB??

Hi,

I think that type="text" does not use the jdbc java.sql.Clob but java.lang.String.

Can you try with type="clob" (and you java attribute should be of type java.sql.Clob)

Regards,
Franck.
