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

Hi,

For Total No Of Employees

Select Count(ID) as [Total No Of Employees] from Employee

For Total No Of Employees for Each Department

Select Count(e.ID) as [Total No Of Employees for Each Department], d.ID, d.deptName from Employee e
Inner Join Department d on d.ID = e.Dept
Group By d.ID, d.deptName
