Hmmm... That is strange. but according to the PostgreSQL documentation on select you can add the
option [AS] keyword between the table_name and alias.
http://www.postgresql.org/docs/8.1/interactive/sql-select.html [ ONLY ] table_name [ * ] [ [ AS ] alias [ (
column_alias[, ...] ) ] ]
( select ) [ AS ] alias [ ( column_alias [, ...] ) ]
select a.inspect_id, a.inspect_result_id, a.inspect_result_pass, a.inspect_result_timestamp
from t_inspect_result AS a
join
(
select max(t_inspect_result.inspect_result_timestamp) as mstamp, t_inspect_result.inspect_id
from t_inspect_result
group by t_inspect_result.inspect_id
) AS b
on a.inspect_result_timestamp = b.mstamp
;
