Обсуждение: Omission of 'FROM' ? diff between pgsql 7.4.1 and pgsql 8.1.4
hi I am upgrading from pgsql 7.4.1 to pgsql 8.1.4. However, some of the application queries won't run on the newer version of pgsql. An example of the type of query is: SELECT protein_external_links.protein_id, external_links.external_id, proteins.public_name WHERE protein_external_links.external_link_id = external_links.id and protein_external_links.protein_id = proteins.id and external_links.external_database_id != 8 and external_links.external_id_type_id = 2; on pgsql7.4.1 what tables need to be queried seems to be implicitly deduced from the rest of the SQL without the need for a FROM clause. However, on pgsql 8.1.4 the following error is given: ERROR: missing FROM-clause entry for table "protein_external_links" Is there some query optimization config setting I can set in pgsql 8.1.4 to fix this problem rather than having to change the queries in the code? I've read over the changes between pgsql 7 and pgsql 8 but nothing seems to stand out to me as referencing this problem. Anyone with more knowledge that can point me in the right direction? Thanks Kate

Look here for "add_missing_from" - http://www.postgresql.org/docs/8.1/static/runtime-config-compatible.html#RUNTIME-CONFIG-COMPATIBLE-VERSION -- Milen A. Radev

'add_missing_from = true' in the postgresql.conf http://www.varlena.com/GeneralBits/Tidbits/annotated_conf_e.html But, you should rewrite your SQL...
