Assuming juergen d's joins of the table are correct, I will modify the query to
select top 2 company_name, e.employee_name
from compyny c
join company_has_employee ce on ce.company_id = c.id
join employee e on e.id = cs.employee_id
group by company_name
having count(e.id) > 1
This will always return the top 2 employees
juergen d's original query will always return the first and last employees based on their ID.
If you want two employees chosen randomly, then you can try this:
select top 2 company_name, e.employee_name
from compyny c
join company_has_employee ce on ce.company_id = c.id
join employee e on e.id = cs.employee_id
group by company_name
having count(e.id) > 1
order by RAND((e.ID)*DATEPART(millisecond, GETDATE()))
The last order by clause will change the order of records randomly and you will always get the top 2 of a random order...which means 2 random employees will be selected each time the query is run.
