I've been trying to use the JOIN syntax in the FROM clause instead of burying all the joins in the WHERE. (Does postgresactually support outer joins now? the user manual seems to imply it does, which version do I need as a minimum?) The resulting query is much simpler than my old UNION SELECT cascade, but I must have done something wrong because I get a parse error. Here's the query and the error.(formatted for monotype) SELECT ldr.peopleid, ldr.firstname, ldr.lastname, ldr.name, flw.peopleid, flw.firstname, flw.lastname, flw.name FROM (people LEFT JOIN organizatios ON organization=orgid) AS ldr, (poeple LEFT JOIN organizatios ON organization=orgid) AS flw, couples WHERE ldr.peopleid=leader and flw.peopleid=follower ORDER BY ldr.lastname, ldr.firstname, flw.lastname, flw.firstname; Warning: PostgreSQL query failed: ERROR: parser: parse error at or near "," 1) What is the problem with my query? 2) Is there any good way to move the last two joins into the FROM?
