[Bug](V9.2.0) LEFT OUTER JOIN on metadata gives wrong result

[hiroyuki0415]

LEFT OUTER JOIN behaves like INNER JOIN:

SELECT a.entitylogicalname,
       a.attributetypename,
       a.logicalname,
       a.targets,
       p.logicalname
FROM   metadata.attribute AS a
       LEFT OUTER JOIN
       metadata.entity AS p
       ON a.targets = p.logicalname
WHERE  a.entitylogicalname IN ('team');
