I have never seen this done before, but it seems like it is supposed to work from reading the manual.
I want to be able to get a table name from another table and use it in the from clause of a select. Something like SELECT * FROM (SELECT name FROM bar WHERE conditions) AS b WHERE b.condition = xxx; which translates to something like SELECT * FROM Dealer AS b WHERE b.zipcode = 12345; The translated version works but the SELECT in FROM version reports that b.condition does not exist. ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
