Jess Balint closed CALCITE-5336. -------------------------------- Resolved in release 1.33.0 (2023-02-06) > Support inferring constants from predicates with IS NOT DISTINCT FROM operator > ------------------------------------------------------------------------------ > > Key: CALCITE-5336 > URL: https://issues.apache.org/jira/browse/CALCITE-5336 > Project: Calcite > Issue Type: Improvement > Components: core > Reporter: Jasmin Trada > Assignee: Jasmin Trada > Priority: Trivial > Labels: pull-request-available > Fix For: 1.33.0 > > Original Estimate: 168h > Time Spent: 20m > Remaining Estimate: 167h 40m > > Whenever we have {{IS NOT DISTINCT FROM}} operator in a predicate, the > {{predicateConstants}} method in {{RexUtil}} is not able to identify the > constants. > E.g., If we make a predicate as given below, > {code} > //dec20 = IS_NOT_DISTINCT_FROM($0, CAST(2020-12-11):DATE) > RexNode dec20 = rexB.makeCall(IS_NOT_DISTINCT_FROM, > rexB.makeInputRef(dateColumnType, 0), > rexB.makeLiteral(new DateString(2020, 12, 11), dateColumnType, > false)); > {code} > and if we call {{RexUtil.predicateConstants(RexNode.class, rexB, > Arrays.asList(dec20))}}, > it will return an empty map, but it should have returned something like this: > {code} > { "$0" -> "CAST(2020-12-11):DATE"} > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
