Steven Talbot created CALCITE-4159: -------------------------------------- Summary: RexSimplify should simplify more always true OR expressions Key: CALCITE-4159 URL: https://issues.apache.org/jira/browse/CALCITE-4159 Project: Calcite Issue Type: Improvement Reporter: Steven Talbot
The following filters for a number are always true {noformat} x > 0 or x <= 0 or x is null x < 0 or x >= 0 or x is null x < 1 or x > 0 or x is null{noformat} where the 1/0 can be replaced by any number where the first is greater than the second The following filter for a varchar is always true: {noformat} x LIKE '%' OR x is null{noformat} It would be nice if RexSimplify.simplifyOrTerms handled these cases. -- This message was sent by Atlassian Jira (v8.3.4#803005)
