Hi all,
I don't understand why this query:
select count(base.*) from mytable base;
does return multiple rows.
select count(1) from mytable base;
returns the proper count.
There is a column with the name 'count'.
Can anyone please explain this behaviour?
Steps to reproduce:
create table s91("count" int);
insert into s91 values (1),(2),(3);
select count(base.*) from s91 base;
count
-------
1
2
3
(3 rows)
I think this is either a bug or an undocumented feature?
ps. I posted this question on StackOverflow as well:
