嵌套选择不适用于配置单元

Question

FROM (
 SELECT upper(name), salary, deductions["service tax"] as service_tax,
 round(salary * (1 - deductions["service tax"])) as salary_minus_service_taxes
 FROM employees
 ) e
 SELECT e.name, e.salary_minus_service_taxes
 WHERE e.salary_minus_service_taxes > 70000;

运行上面的查询时，我得到以下错误

该列应使用别名：

SELECT upper(name) as name
