SELECT wl.ts,wa.name,wl.user_id,u.name,wl.doc_id,d.doc_id,wl.docrev_id,dr.docrev,wl.file_id,f.fname,wl.issue FROM worklogs AS wl, workactions AS wa, users AS u LEFT JOIN documents AS d ON wl.doc_id=d.id LEFT JOIN docrevs AS dr ON wl.docrev_id=dr.id LEFT JOIN files AS f ON wl.file_id=f.id WHERE wl.action_id=wa.id AND wl.user_id=u.id ORDER BY wl.ts DESC;
When I run this I get the error:
-------------------- ERROR: invalid reference to FROM-clause entry for table "wl" LINE 3: LEFT JOIN documents AS d ON wl.doc_id=d.id ^ HINT: There is an entry for table "wl", but it cannot be referenced from this part of the query. --------------------
You should write out all of your joins explicitly.
FROM worklogs
JOIN workactions ON
JOIN users ON
LEFT JOIN documents ON
LEFT JOIN docrevs ON
LEFT JOIN files ON
--there were no non-join conditions in your where clause so it is omitted here
ORDER BY
Mixing "FROM tbl1, tbl2 WHERE" and "FROM tbl1 JOIN tbl2 ON" syntax just causes grief.
