Hi, For the query below, versions 3.8.11.0 and 3.8.11.1 return only 1 row. For some reason, the LEFT JOIN seems to behave like a JOIN.
Older versions (tested 3.8.7.4 and 3.8.10.2) correctly return 2 rows.
SELECT *
FROM (
SELECT 'apple' fruit
UNION ALL SELECT 'banana'
) a
JOIN (
SELECT 'apple' fruit
UNION ALL SELECT 'banana'
) b ON a.fruit=b.fruit
LEFT JOIN (
SELECT 1 isyellow
) c ON b.fruit='banana'
;
regards,
Mark
