duan xiong commented on CALCITE-4805: ------------------------------------- [~julianhyde] Thanks. I have modified it. > Calcite should convert a small IN-list as if the user had written OR, even if > the IN-list contains NULL > ------------------------------------------------------------------------------------------------------- > > Key: CALCITE-4805 > URL: https://issues.apache.org/jira/browse/CALCITE-4805 > Project: Calcite > Issue Type: Bug > Components: core > Reporter: duan xiong > Assignee: duan xiong > Priority: Major > Fix For: 1.28.0 > > > Since CALCITE-373 Calcite has converted "x IN (1, 2)" to "x = 1 OR x = 2" but > it still converts "x IN (1, NULL)" to "x IN (VALUES 1, NULL)" and that, since > some bugs have been fixed, there's no good reason for the difference. > For example: > {code:java} > select * from emp where deptno in (null,2){code} > Now the RelNode is: > {code:java} > LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3], HIREDATE=[$4], > SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8]) > LogicalJoin(condition=[=($7, $9)], joinType=[inner]) > LogicalTableScan(table=[[CATALOG, SALES, EMP]]) > LogicalAggregate(group=[{0}]) > LogicalValues(tuples=[[{ null }, { 2 }]]){code} > The RelNode should be: > {code:java} > LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3], HIREDATE=[$4], > SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8]) > LogicalFilter(condition=[OR(=($7, null), =($7, 2))]) > LogicalTableScan(table=[[CATALOG, SALES, EMP]]){code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
