Hi, all.
I'm using V6.4.2 on RedHat Mandrake 6.0, and when I run the following
query, the backend says:
pqReadData() -- backend closed the channel unexpectedly
Here is the culprit:
SELECT Sno
FROM Take
WHERE Cno = 'CS112'
AND Cno NOT IN
(SELECT Sno FROM Take
WHERE Cno != 'CS112');
It's out of the book 'The Essence of SQL' by David Rozenshtein, which I am
reading and working through. Other queries from the book run fine.
I can't find any reference to the reason for this in pm.log - is there
somewhere else I should be looking?
