In PostgreSQL 7.4, the following select:
select texten, total
from (select protocolid, count(*) as total) from ips where catid=1
group by protocolid order by protocolid) as c
inner join protocols using (protocolid);
gives the error message:
ERROR: subquery in FROM must have an alias
HINT: For example, FROM (SELECT ...) [AS] foo.
Why isn't the "as c" considered as an alias?
