Hello.
Concerning DERBY-1610, I'm surveying type definition part in current
DRDA relating code.
I found there exists two word "DRDA_TYPE" and "FDOCA_TYPE".
Former was found in org.apache.derby.iapi.reference.DRDAConstants and
latter was found in org.apache.derby.client.net.FdocaConstants.
The latter seems to be FTYPE defined in FD:OCA Specifications.
However I'm not sure what former is....
Does any one know what is DRDA_TYPE is ?
Best regards.

Tomohito Nakayama commented on DERBY-1610:
------------------------------------------
Reading the code, it seems that NetworkServer recognize the type of the
parameter, according to the SQL and not according to the method which passes
the parameter value.
SQL to be executed in the TestNullChar.java is as next and type of the
parameter is recognized as CHAR.
INSERT INTO NULL_CHAR_TEST(CHAR_VALUE) VALUES(?)
Ground of my reading is that type data is retrieved from Statement and not from
FDODSC of SQLDTA.
Engine take it as type compatibility error to update column typed as CHAR to
value passed via setBinaryStream(null), though Network Client and Network
Server does not take it as error.

There exists difference between Engine and Network Client/Engine around type
compatibility judgement in character typed column when null value was passed as
InputStream.
