I've got a join where a certain column name appears twice: select username,last_name from eg_member join eg_membership using (member_id) join eg_account using (account_id) join eg_person using (person_id); ERROR: common column name "person_id" appears more than once in left table
My first inclination was to fully quality the table name. Why would this not be acceptable syntax? select username,last_name from eg_member join eg_membership using (member_id) join eg_account using (account_id) join eg_person using (eg_member.person_id); ERROR: syntax error at or near "." at character 145 Of course I eventually wrote it: select username,last_name from eg_member join eg_membership using (member_id) join eg_account using (account_id) join eg_person on eg_member.person_id=eg_person.person_id'; PostgreSQL 8.1.9 on i686-redhat-linux-gnu, compiled by GCC gcc (GCC) 4.1.1 20070105 (Red Hat 4.1.1-51) -- ---- Visit http://www.obviously.com/ ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
