Subject [jira] Updated: (DERBY-1610) 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.

Tomohito Nakayama updated DERBY-1610:
-------------------------------------

    Attachment: DERBY-1610.diff
                parameterMapping.diff

I tried to guess type of java.sql.Type when value was null ,
from drdaType as the patch.

As the result, the NetClientTest of  jdbcapi/parameterMapping.java was failed and got amount
of difference.

I think this difference is too large to accept.
Originally, DERBY-1610 was issue around setBinaryStream(null).

Remembering the original problem, 
it was more problematic point of this issue that setBinaryStream(null) to character colum
was failed though setBinaryStream(notNull) to character column was successed, than difference
between Engine and NetworkServer/NetworkEngine.
