Description
When the following capabilities are set on ExecutionFactory
setSupportsOuterJoins(true);
setSupportedJoinCriteria(SupportedJoinCriteria.KEY);
A three table JOIN like
select G1.e1, G2.e1, G3.e1 from G1, G2, G3 where G1.e1=G2.e2 and G2.e2 = G3.e3
gets pushed to translator as two separate queries like
SELECT G3.e3 AS c_0, G3.e1 AS c_1 FROM G3 ORDER BY c_0 SELECT G2.e2 AS c_0, G1.e1 AS c_1, G2.e1 AS c_2 FROM G1 LEFT OUTER JOIN G2 ON G1.e1 = G2.e2 WHERE G2.e2 IS NOT NULL ORDER BY c_0
instead of of one query which should be like
SELECT G1.e1, G2.e1, G3.e1 FROM G1 INNER JOIN G2 ON G1.e1 = G2.e2 INNER JOIN G3 ON G2.e2 = G3.e3
When the key restriction is removed, it works fine, which should be un-related.
