Hongze Zhang commented on CALCITE-2999:
---------------------------------------
Sorry maybe I missed something but I don't quiet get the problem from the
Project expression list that you highlighted. Do you mean the RexInputRef
{{"$4"}} does not offer a correct field ordinal?
It would be good if you can explain your issue in detail. For example, you can
paste the wrong logical plan Calcite produced and the correct plan you
expected, that helps you to explain the issue.
> Can't get the right column value in LogicalSort
