Need help coming up with an sql query for my problem

What I want to do is count the number of employees a publisher employs and then report a list of the names of the publishers along with the total amount of employees. This list is to be ordered by publishers who have the most employees listed first.

Here is a sample of the database. This is actually two databases joined together. So the databases are called publishers, employee.

pub_id  pub_name     开发者_C百科   city   state/country/emp_id fname minit lname   job_id job_lvl  pub_id hire_date

Something like this should work:

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


SELECT pub_name, COUNT( emp_id ) AS emp_quan
FROM  `table_name` 
GROUP BY pub_name
ORDER BY emp_quan

Knew that was gonna happen, a second too late :)
