Sorry if this has been answered before but a dejanews search turned up nothing relevant. I'm trying to select from a table which has a couple of array columns, and I want to constrain the select on those columns, i.e. something like (pseudo-code) select date,loc from results where value appears in temperature results table: date loc temperature (int4[]) 12/01/98 4th & Main {12, 14, 14, 15, 17, 19, 25, ...} 12/04/98 Station 4 {12, 13, 14, 666, 18, 20, 24, ...} I want to select only those rows where one of the recorded temps is equal to , say, 17 , and also to select a range (rows where temp > 20, or where temp < 10). I might also want to select rows where the temp could not be measured (indicated by 666) at a certain period. I can do it if I step through each of the temperature values and compare each one, but this seems needlessly inefficient. Is there a quick way to retrieve these rows?
