Hi,

I have a table with a number field, some varchar fields, a blob field, and 2
date fields. All the tests of inserting of messages into this table went
fine until I made a test with 47000 different messages. There I had 15
messages with the error:

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

I can't see any difference in these failed messages compared to the others.
The exception is thrown from the db.create() function. I switched on the log
writer of castor, but there is no information what happens during the
create. 

Any ideas?

Thanks.
Juergen
