Ran Tao created CALCITE-6041:
--------------------------------
Summary: Map query failed with NullPointerException in runtime
phase
Key: CALCITE-6041
URL: https://issues.apache.org/jira/browse/CALCITE-6041
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.35.0
Reporter: Ran Tao
calcite support array/map/multiset query constructor, but if we run map query
such as:
{code:java}
select map(select 1, 2)
select map(select empno, deptno from emps); {code}
If will cause exception:
{noformat}
java.sql.SQLException: Error while executing SQL "select map(select 1, 2)":
