The ORM generated a query with INNER JOIN instead of LEFT OUTER JOIN in a somewhat complicated case. The main issue was that there was a chain of nullable FK -> non-nullble FK, and the join promotion logic didn't see the need to promote the non-nullable FK even if the previous nullable FK was already promoted to LOUTER JOIN. This resulted in a query like a LOUTER b INNER c, which incorrectly prunes results. |
