Hi Craig, Kathey,
First, it seems someone took my subtle attempt at humor the wrong way.
My apologies as I was not trying to insult or offend anyone (but it was
9:40pm EDT and I had been working since 6am to meet some deadlines).
My point was, that I cannot guarantee that a vendor is not throwing a
SQLException in the case where the length is 0, someone might have
chosen to do this, i do not know. The spec does not articulate a
specific behavior one way or the other so from a spec perspective, they
are within their rights to do so as the API does not define the
behavior. This was what i was referring to in my attempt at late night
humor. I have been surprised many times over as to how some items have
been implemented by vendors given the lack of clarity.
I think i will sign off derby-dev for a while...

Hi Lance,
Unless I'm missing something, a zero length java.lang.String is legal
and necessary for completeness. Since there's nothing in the quoted
text, I'd assume that a zero-length String should be returned as long
as the start position is legal. Not an exception, not null, not
"nothing", but a valid zero-length String.

Hi Kathy,
I would probably expect a SQLException to be thrown in this case or
I guess you could return nothing.
We did not discuss this stupid human trick in the EG :-) but i guess
we should have.

Derby is correct. The clarified JDBC 4 javadocs indicates the
following:
|pos| - the first character of the substring to be extracted.
The first character is at position 1.
|length| - the number of consecutive characters to be copied
Thanks Lance for looking at this. The question is about the
length. The length in this case is 0.
From the DDLUtils code it looked like this where clob.length() was 0.
value = clob.getSubString(1, (int)clob.length());
Is this ok to send length 0 or to specify position 1 if there is no
character there?
