I am getting this error: PGError: ERROR: missing FROM-clause entry for table "ca_customs_entry" LINE 1: ..._entries"."is_cadex_transmitted" = 'f') ORDER BY ca_customs... The code is generated by a Ruby-on-Rails-3.0.1 ActiveRecord model: SELECT "ca_customs_shipments".* FROM "ca_customs_shipments" INNER JOIN "ca_customs_entries" ON "ca_customs_entries"."ca_customs_shipment_id" = "ca_customs_shipments"."id" WHERE ("ca_customs_entries"."is_cadex_transmitted" = 'f') ORDER BY ca_customs_entry.is_across_transmitted, ca_customs_entry.is_across_rejected, ca_customs_entry.is_across_accepted, ca_customs_entry.is_cadex_released LIMIT 5 OFFSET 0 >From what I have been able to piece together for myself I suspect that the cause may be the absence of an 'AS "alias"' immediately following the 'FROM "ca_customs_shipments"' segment. PG evidently treats this as required element whereas standard SQL does not. If someone could confirm that my suspicions are well founded then I will raise an issue to handle the matter with the software maintainers. On the other hand, if there is another cause of this then I would like to have that information as well. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.
