【问题描述】：

目的是使用 where 子句连接同一个表并检索两个不同的列

SELECT a.analyst_assigned
     , count(a.case_id) AS Pending
     , count(b.case_id) AS Completed
     , sum(b.total_errors) AS Errors
  FROM cases_main as a
 WHERE a.team_qc1_qa2 = "qa" 
   and a.q_status in ("Not Started","Under Review","Follow-up") 
   and a.p_date_worked between #03/08/2021# and #03/14/2021#

    INNER JOIN cases_main as b

    ON a.analyst_assigned = b.analyst_assigned

 WHERE b.team_qc1_qa2 = "qa" 
   and b.q_status in ("Completed: No Error","Completed: Feedback") 
   and b.p_date_worked between #03/08/2021# and #03/14/2021#

 GROUP 
    BY b.analyst_assigned;

【问题讨论】：

为什么是 MySQL 标签？是什么让你认为你错了（Akina 我很想知道 OP 的答案，而不是你的）
我错了 首先是 FROM 和所有 JOIN，然后是 WHERE。不是从哪里加入哪里。 PS。使用 master 来构建正确的查询。

【解决方案1】：

试试这个更简单的方法：

SELECT a.analyst_assigned
    , abs(sum(q_status Like "Completed*")) AS Pending
    , abs(sum(q_status Not Like "Completed*")) AS Completed
    , sum(b.total_errors) AS Errors
FROM cases_main as a
WHERE a.team_qc1_qa2 = "qa" 
    and a.p_date_worked between #03/08/2021# and #03/14/2021#
GROUP BY a.analyst_assigned
