Knut Anders Hatlen commented on DERBY-2017:
-------------------------------------------
I agree that it would be good to get the same error on both drivers for the
situations above.
The situation I had in mind was slightly different. I was thinking of the case
where the user stream throws an exception when it's read. In the current code,
I believe that both the client driver and the embedded driver will expose the
original exception thrown by the user stream. If we disable the accumulation of
exceptions, will we then instead see the below exception on the client?
+ case DRDAConstants.STREAM_READ_ERROR:
+ case DRDAConstants.STREAM_READ_ERROR_ON_LEN_VAL:
+ throw new IOException("Read error on client side when " +
+ "reading user stream");
My preference would be that we continued to report the original exception in
such a situation.

> When a LOB stream throws an exception or does not match the specified length,
> the client driver does not raise an exception until it has finished executing
> the statement. Therefore, the statement will be executed (and possibly
> committed) on the server even though the client reports that the statement
> failed.
