OmniOperator: Spark window does not support lieteral expression

[XiaoqiMa]

子查询中含有常量表达式作为投影列，然后在外层作为窗口函数的分组列，转化为列引用失败出错了

SELECT
statis_cycle_sign, name, dept, salary, ROW_NUMBER() OVER (PARTITION BY statis_cycle_sign, name, dept ORDER BY salary) AS rank
FROM
( SELECT 'pt_today' AS statis_cycle_sign, name, dept, salary, age from employees) ;
