For example, if > we use some of this queries: > {code:sql} > select ... FROM t1, t2 WHERE t1.c1 = t2.c2 OR (t1.c1 IS NULL AND t2.c2 IS > NULL); > select ... FROM t1 INNER JOIN t2 ON t1.c1 = t2.c2 OR (t1.c1 IS NULL AND > t2.c2 IS NULL); > {code} > we got "UNSUPPORTED_OPERATION ERROR". We should add support for this option. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
