Roman created DRILL-4926: ---------------------------- Summary: Add support for Null Equality Joins Key: DRILL-4926 URL: https://issues.apache.org/jira/browse/DRILL-4926 Project: Apache Drill Issue Type: Improvement Components: Query Planning & Optimization Affects Versions: 1.8.0 Reporter: Roman Assignee: Roman
Join with an equality condition which allows null=null fails. 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 of this option. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
