Subject [jira] Commented: (DERBY-1610) Updating column typed as CHAR to value passed via setBinaryStream(notNull) is failed because of imcompatiblity of types though it was not taken as error when setBinaryStream(null)

Knut Anders Hatlen commented on DERBY-1610:
-------------------------------------------

Hi Tomohito,

The BatchUpdateException indicates that the error happens when executeBatch() is invoked,
not when setXXX() or addBatch() is called. I think this is OK, but it would of course be better
if the exception were raised in setXXX().

If you want to ignore these errors in parameterMapping.java, you could wrap each call to executeBatch()
like this:

try {
    psi.executeBatch();
} catch (BatchUpdateException bue) {
    SQLException reason = bue.getNextException();
    throw (reason == null) ? bue : reason;
}

Also, do you think a release note is needed for this issue? If I understand correctly, the
client driver (and possibly JCC) will throw an exception in situations where they didn't throw
an exception before.

and updating the column to value passed via setBinaryStream(null).
> This difference is problematic because it does not exist in Embedded mode.
