    • Type: Bug

    • Priority: Critical
    • Resolution: Fixed

      Description

      Query:

      select 
        cast(sum(dc)*100 as decimal(11,3)) as c1
        from somedecimaltable
        order by c1
        limit 100;
      

      Fails during execution initialization due to null ExprNodeDesc.

      Noticed while trying to simplify a Vectorization issue and realized it was a more general issue.
