NAGY Andras ([EMAIL PROTECTED]) reports a bug with a severity of 2
The lower the number the more severe it is.
Short Description
views containing aggregates
Long Description
Not sure, whether the `Views containing aggregates sometimes fail' and `Allow views of
aggregate columns' entries from the TODO cover this, therefore the bug report. An
aggregate select from a view containing aggregates behaves differently as expected.
Even if the support for this is on TODO, until fixing this, postgres should print a
warning or otherwise reject such use of views.
Sample Code
create table example (
name text
);
insert into example values('alpha');
insert into example values('alpha');
insert into example values('alpha');
insert into example values('alpha');
insert into example values('beta');
insert into example values('beta');
insert into example values('gamma');
-- the following should always return the number
-- of rows a simple `select * from relation' would return
select count(*) from example;
count
-------
7
(1 row)
create view example_view as select name from example group by name;
select * from example_view;
name
-------
alpha
beta
gamma
(3 rows)
-- however, it is not the case here
select count(*) from example_view;
count
-------
4
2
1
(3 rows)
