Your question is :
how can i count total number of employees in each department and department name

You can use the group by clause in your query.

for example the following query will give you the total number of employees and depart name

Select COUNT(Employee.id) as TotalEmployees ,Department.ID,Department.DepartmentName from Employee inner join Department on Employee.Dept=Department.ID GROUP BY Department.ID,Department.DepartmentName
