日期范围为的PostgreSQL更新

我有一句话很有效，但它是不受约束的，因为它总结了整个专栏，我想介绍日期范围，但我得到了一个错误

这就是有效的方法

UPDATE payroll_employee e
    SET hours = l.total
FROM (SELECT employee, SUM(end_date - start_date) AS total
    FROM payroll_timelog
    GROUP BY employee) l
WHERE e.id = l.employee

我想介绍一个日期过滤器。 然后我尝试了这个CTE

WITH cte AS (
  SELECT employee_id, end_date SUM(end_date - start_date) AS total
    FROM payroll_timelog
    WHERE employee_id = 1, AND end_date > 2020-09-01
)
UPDATE payroll_employee e
   SET hours = total
FROM cte
WHERE e.id = 1;

已尝试将日期设置为2020-09-01：：日期、2020-09-01：：时间戳等，但仍然无效。任何帮助都将不胜感激。

我想您只是有语法错误：

WITH cte AS (
      SELECT employee_id, SUM(end_date - start_date) AS total
      FROM payroll_timelog
      WHERE employee_id = 1 AND end_date > '2020-09-01'
      GROUP BY employee_id
)
UPDATE payroll_employee e
   SET hours = cte.total
FROM cte
WHERE e.id = 1;

“行不通”是什么意思？添加输入参数和预期结果。

和

前面有一个逗号，因此查询不会解析。get:语法错误位于或接近“（“第2行：选择员工id，结束日期和（结束日期-开始日期。。。
