duan xiong created CALCITE-4805: ----------------------------------- Summary: When IN sub-query valueList contains Null literal, can't be converted to OR. Key: CALCITE-4805 URL: https://issues.apache.org/jira/browse/CALCITE-4805 Project: Calcite Issue Type: Bug Reporter: duan xiong Assignee: duan xiong
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} So I think when the sub-query value list size is under the threshold(IN_SUB_QUERY_THRESHOLD), they can be converted to OR(no matter have the NullLiteral or not). -- This message was sent by Atlassian Jira (v8.3.4#803005)
