Depends on how you want to define "largest" and "smallest", but if "area" is a good enough definition, seems like this would work: select file_md5 from image_instance where md5 = '546b94e94851a56ee721f3b755f58462' and image_width between 0 and 160 and image_length between 0 and 160 order by image_width * image_length limit 1; Probably an index on md5 would be sufficient to make this go fast --- I assume you're not going to be storing a vast number of sizes of the same image. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
