需要帮助提出我的问题的SQL查询

Question

我想要做的是计算出版商雇用的员工数量,然后报告出版商名称列表以及员工总数.此列表由首先列出最多员工的发布商订购.

这是数据库的示例.这实际上是两个数据库连接在一起.因此,数据库称为发布者,员工.

pub_id  pub_name        city   state/country/emp_id fname minit lname   job_id job_lvl  pub_id hire_date

Answer 1

这样的事情应该有效:

SELECT pub_name, COUNT(emp_id) 
FROM your_table_or_view_or_subquery
GROUP BY pub_name
ORDER BY COUNT(emp_id) DESC, pub_name
