Hello: I've been working with databases for several years now (primarily MS SQL Server) and have recently started working with Postgresql on a trial basis. I can't seem to get subqueries to work in postgresql. For example, below is a simple dump of my table weather: meltest=> select * from weather; city | temp_lo | temp_hi | date ---------------+---------+---------+------------ San Francisco | 46 | 50 | 1994-11-27 Los Angelos | 49 | 55 | 1994-11-28 (2 rows) If I try to do a subselect as follows, I get a parsing error: meltest=>select * from (select * from weather) as w; ERROR: parser: parse error at or near "select" I don't see anything wrong with the SQL syntax, even after comparing it against the on-line documentation. Can someone please point out what's wrong with this syntax? I know it works on MS SQL Server - do you have to do it differently in Postgresql? Any help would be appreciated.
