James Kim created CALCITE-4092:
----------------------------------
Summary: NPE using WITH clause without a corresponding SELECT FROM
Key: CALCITE-4092
URL: https://issues.apache.org/jira/browse/CALCITE-4092
Project: Calcite
Issue Type: Bug
Reporter: James Kim
Running the below query:
{code:java}
final String sql = "with emp2 as (select max(empno) as empno from emp where
empno > 10)\n"
+ "select drill.* from emp drill where drill.empno < emp2.empno";
{code}
We hit NPE
{code:java}

{code}
This can be prevented by running the below query instead (difference from the
first query is in red):
{code:java}
final String sql = "with emp2 as (select max(empno) as empno from emp where
empno > 10)\n" + "select drill.* from emp drill, emp2 where drill.empno <
emp2.empno";
{code}
I'm not sure whether the first query is valid and should be performed to
properly produce results or is invalid and the error message should be made to
be something more informative than a NPE. In the case of the latter, the error
message could be a table not found error that is thrown at the query validation
step.
