I just experienced some bad SQL causing quite unexpected results.
I used a statement like this:
SELECT t1.a, t1.b, t2.d FROM test1 t1, test2 t2 WHERE t1.a = test2.a;
Where I should have used this instead:
SELECT t1.a, t1.b, t2.d FROM test1 t1, test2 t2 WHERE t1.a = t2.a;
When I looked into it and tried it from psql, I got this notice:
NOTICE: adding missing FROM-clause entry for table "test2"
Now, I understand that postgresql is adding "test2" to the list of
tables, I am selecting from as it is missing. However the result
is quite different from what I expected.
Is there a way to change this behaviour to generate an error instead
of just a notice?
