Java Database Connectivity (JDBC)

As posted in metalink (was: "Problems inserting BLOB/InputStream with ojdbc14.jar for 10g - Data size bigger than max size for this type"):

Using setBinaryStream for large Blobs works as long as I don't register outParameters.

Query that works: "INSERT INTO blobtest (attachment_id,name,data) VALUES(blobtest_SEQ.nextval,?,?)";

Query that fails = "BEGIN INSERT INTO blobtest (attachment_id,name,data) VALUES( blobtest_SEQ.nextval,?,?) RETURN attachment_id INTO ? ; END;"

------------------
The necessary tables were created by hand:

CREATE TABLE blobtest ( NAME CHAR(255), data BLOB, attachment_id NUMBER(38))

And

CREATE SEQUENCE TBL_ATTACHMENT_SEQ


The output was: <<user: SEE
pw: QD
instantiating oracle driver
query: INSERT INTO blobtest (attachment_id,name,data) VALUES(TBL_ATTACHMENT_SEQ.nextval,?,?)
uploaded no Return Parameter blob of size: 256809
query: BEGIN INSERT INTO blobtest (attachment_id,name,data) VALUES(TBL_ATTACHMENT_SEQ.nextval,?,?) RETURN attachment_id INTO ? ; END;
