Subject [jira] Commented: (DERBY-2652) Clob.setCharacterStream differs between embedded and client driver

Kristian Waagan commented on DERBY-2652:
----------------------------------------

Shall we do anything about this for 10.2, or is that too late anyway? (introducing "incompatible"
behavior between 10.2 releases)
If so, I will close this issue.

> Clob.setCharacterStream behaves differently depending on whether you use the embedded
or the client driver.
> Sample output from the repro:
> (embedded) Initial : 123456789
> (embedded) After   : 12__56789
> (client)   Initial : 123456789
> (client)   After   : 12__
> As can be seen, the client driver truncates the Clob value when it writes to it, whereas
the embedded driver does not and instead replaces existing characters with those written to
the character stream.
> (BTW: I know the title is not perfectly accurate, but it got so long when explaining
that it is when you actually write to the stream returned by Clob.setCharacterStream the result
differs.)
