Question

我有一个有效的MySQL查询，只能获得＃34; Managers Only＆＃34;来自我的tblUsers：

SELECT COUNT(e.username) AS employeeCount,
  m.username             AS reports_to,
  m.id
FROM tblusers e
INNER JOIN tblusers m
ON e.reportsToID = m.ID
GROUP BY m.username

但是我需要另一个只能获得＆＃34;仅限员工＆＃34;？

的查询

Answer 1

感谢所有人，特别是@crai

您的查询运行良好：

    SELECT username, id, reportstoID 
FROM tblusers 
WHERE id NOT IN (SELECT reportsToID FROM tblusers) AND reportstoID <> '0'
ORDER BY username

Answer 2

SELECT 
  username
  , id
  , reportsToID
FROM 
  tblusers e
WHERE
  e.reportsToID<>0
ORDER BY username

MySQL查询显示不是经理的员工？
