在MySQL中编写CTE时发生错误

Question

我在MySQL中有以下查询，但是在执行该查询时会收到语法错误消息：

  

您的SQL语法有错误；检查与您的MySQL服务器版本相对应的手册以获取正确的语法，以在“ WITH CTE1 AS”附近使用（在第1行选择u.FirstName，dayname（t.date）作为Day，Date_Format（t.Date，“”

WITH CTE1 AS
(
select u.FirstName,dayname(t.date) as Day, Date_Format(t.Date,"%Y-%m-%d") As Date,  t.subtask,
IF(subtask='PTO','PTO', hours) as Emphours,

 g1.name
 from user U, task t, groupuser g, `group` g1
where  U.idUser= t.userid and g.userid= U.idUser
and g1.name='Lam-techM' and date >= '2018-11-01' and date <= '2018-11-08'
order by  date asc
)
select * from CTE1;

有人可以帮我吗？
