Hi All,
This is ambarasing, but I've just noticed the following (which looks
inconsistant to inexperienced eye). Having a table:
test=> CREATE TABLE xxx (id int, info text);
With some rows in it, I try:
test=> SELECT count(1) from xxx where id=1;
count
-------
0
(1 row)
This is correct (meaning, I expected that). But when I try to fetch the
actual selector used in the query as well, I get no rows instead.
test=> SELECT count(1),id from xxx where id=1 group by id;
count | id
-------+----
(0 rows)
Is this a feature, or a bug? And in fact, is there a construct to get
both the count() and its selectors *in*case*, when the count is ZERO?
All the above in postgres 8.1.
Thenx.
