Hey Vasile: Cause I have more clauses based on the stock table that I haven't included in the original query. For example:
SELECT date, count(items) FROM ( SELECT logs.date, logs.items FROM logs WHERE extract(year from logs.date) = 2010) GROUP BY date, items ) AS foo, stock WHERE stock.items = foo.items AND stock.type = 'Books' AND ... GROUP by date cheers, On Sat, Jan 29, 2011 at 1:27 PM, Vasile Ermicioi <elff...@gmail.com> wrote: > why do you need 'stock' table ? >>> WHERE >>> stock.items = foo.items
