使用公用表表达式时出现 JOIN 错误

Question

我正在使用下面的表达式来找出哪些“资源”类型的客户拥有处于活动状态的“工作资源”。

WITH cte_ss AS (SELECT wr.user_id
FROM work w
JOIN work_resource wr ON wr.work_id = w.id
WHERE wr.work_resource_status_type_code = 'active'
  ),
SELECT u.uuid
FROM user u
JOIN company c ON c.id = u.company_id
LEFT JOIN cte_ss on cte_ss.user_id = u.id
    AND c.customer_type = 'resource'

White 试图运行它，我得到以下错误

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT u.uuid
FROM user u
JOIN company c ON c.id = u.company_id
LEFT JOIN cte_ss' at line 6

两个单独的查询（没有 LEFT JOIN）都在工作，所以不确定我在这里做错了什么

Answer 1

一个 cte 看起来像这样

但由于我对你的桌子一无所知，你必须自己弄清楚

WITH cte_ss AS (
SELECT 
user_id
FROM work w
JOIN work_resource wr ON wr.work_id = w.id
WHERE wr.work_resource_status_type_code = 'active'
)
SELECT u.uuid
FROM user u
JOIN company c ON c.id = u.company_id
LEFT JOIN cte_ss on cte_ss.user_id = u.id
    AND c.customer_type = 'resource'
