[jira] [Created] (CALCITE-2649) Allow RelBuilder to create field references to aliased relations without knowing the size of the stack

Stamatis Zampetakis created CALCITE-2649:
--------------------------------------------

             Summary: Allow RelBuilder to create field references to aliased relations without knowing the size of the stack
                 Key: CALCITE-2649
                 URL: https://issues.apache.org/jira/browse/CALCITE-2649
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.17.0
            Reporter: Stamatis Zampetakis
            Assignee: Julian Hyde
             Fix For: 1.18.0


As of [CALCITE-1523|https://issues.apache.org/jira/browse/CALCITE-1523] it is possible to create field references to aliased relations anywhere in the stack. However the respective field method requires to pass as a parameter the inputCount (i.e., size of the stack). This is not very convenient since clients of RelBuilder are obliged to track the size of the stack (leading to the uneseccary creation of Wrapper classes).
