             Summary: Improve LogicalWindow print plan to add the constant value
                 Key: CALCITE-5929
                 URL: https://issues.apache.org/jira/browse/CALCITE-5929
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.35.0
            Reporter: xiong duan


In general, we can extract the original SQL from the plan. But when the SQL 
includes the LogicalWindow with a constant value, the Plan didn't print it.

The SQL:
{code:java}
select COUNT(*) over (
ORDER BY empno
ROWS BETWEEN 5 + 5 PRECEDING AND 1 PRECEDING) AS w_count from emp{code}
The Plan:
{code:java}
LogicalProject($0=[$1])
  LogicalWindow(window#0=[window(order by [0] rows between $1 PRECEDING and $2 
PRECEDING aggs [COUNT()])])    
      LogicalProject(EMPNO=[$0])
      LogicalTableScan(table=[[CATALOG, SALES, EMP]]) {code}
In this plan, we don't know the $1 and $2 values.
