Thanks for the response. Yes I'm doing embedded so this is fine for
me. One other question, I have noticed that once I cancel my
PreparedStatement, it does not seem to work again. I couldn't find a
way to clear it, so I guess I have to re-instantiate it?
Also, how promptly should this cancel take effect? It seemed to be
fairly delayed, but there's still a chance my implementation wasn't
correct.
Hi,
You are right, a PreparedStatement could not be reused after cancel was called.
I have fixed this and added a test case. Thanks for reporting this!
Delayed cancel: if you use the database in embedded mode, it depends on thread
scheduling when the statement is cancelled (you need two threads). I also got
this problem. What I did is use Thread.yield in my test, like this:
CREATE ALIAS YIELD FOR "java.lang.Thread.yield";
SELECT YIELD() FROM ...
So for each row, Thread.yield() is called, letting other threads do some work.
Another solution would be to use SET THROTTLE (see docs).
