count - 计数和左连接不能正常工作

Question

尝试对这些行进行计数 COUNT(engineerName) ASengineerCount, Count(managerName) as managerCount, Count(isContractor) ascontractorCount 但它始终返回所有三个相同的数字。所以我试图为每个添加一个 Where，Example Count(isContractor where isContractor = 'yes') ascontractorCount 但遇到错误请帮忙，谢谢。

Answer 1

SELECT 
  market,
  areaName,
  COUNT(engineerName) AS engineerCount,
  Count(managerName) as managerCount,
  Count(isContractor) as contractorCount
FROM
  employee.employees
GROUP BY market

应该

Group By market,areaName猜测。

这就是它所能看到的一切，因为您几乎没有提供任何有用的信息。
