Chunwei Lei created CALCITE-3803: ------------------------------------ Summary: Enhance RexSimplify to simplify 'a>1 or (a<3 and b)' to 'a>1 or b' if column a is not nullable Key: CALCITE-3803 URL: https://issues.apache.org/jira/browse/CALCITE-3803 Project: Calcite Issue Type: Improvement Components: core Reporter: Chunwei Lei Assignee: Chunwei Lei
For {{a>1 or (a<3 and b)}}, with short-circuit, we know {{a<=1}} if {{a>1}} is false when column a is not nullable. Then {{(a<3 and b) }}can be simplified to {{b}}. Thus, {{a>1 or (a<3 and b) }}is simplified to {{a>1 or b.}} -- This message was sent by Atlassian Jira (v8.3.4#803005)
