[GENERAL] PGError: ERROR: missing FROM-clause entry for table
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.

You need to either set a matching alias, or fix the table name qualifier in those order by columns. Robert Treat play: xzilla.net work: l42.org/lg

You need to either set a matching alias, or fix the table name qualifier in those order by columns. That was exactly the problem. Thank you very much. I am afraid that the mental gymnastics that Rails requires--table names are plural, corresponding model classes are singular--often trips me up. I would never have seen that error on my own. -- *** E-Mail is NOT a SECURE channel *** James B.
