Subject [jira] Commented: (DERBY-102) can not insert more than 32270 charakters in long varchar, clob
Date Mon, 13 Dec 2004 17:47:56 GMT
     [ http://nagoya.apache.org/jira/browse/DERBY-102?page=comments#action_56591 ]
     
Sunitha Kambhampati commented on DERBY-102:
-------------------------------------------

--I believe these are the limits currently enforced :-
VARCHAR maximum length 32 672 
LONG VARCHAR maximum length 32 700 
CLOB maximum length 2 147 483 647 
BLOB maximum length 2 147 483 647 
and hence the insert of 32800 chars into long varchar fails. 

So it seems these didnt make it into the documentation. The following page will need to reflect
the correct limit: http://incubator.apache.org/derby/manuals/reference/sqlj137.html#IDX1005

Also lot of the limits live in org.apache.derby.iapi.reference.DB2Limit

--I would think you should be able to insert into a clob. If you could post the test reproduction
or SQLExceptions that you are getting for inserting a clob, along with traces in derby.log,
that would be great.
