I have 3 queries that I need combined into one. Here they are

SELECT COUNT(e.EmployeeID) AS TotalEmpCount
FROM Employees as e
WHERE HomePhone <> ''

SELECT COUNT(e.EmployeeID) AS USEmpCount
FROM Employees as e
INNER JOIN Orders as o ON e.EmployeeID=o.EmployeeID
WHERE e.HomePhone <> '' AND e.Country='US' AND o.OrderDate BETWEEN '11/01/2011' AND GETDATE()


SELECT COUNT(e.EmployeeID) AS UKEmpCount
FROM Employees as e
INNER JOIN Orders as o ON e.EmployeeID=o.EmployeeID
WHERE HomePhone <> '' AND Country ='UK' AND o.OrderDate BETWEEN '01/01/2011' AND '12/31/2012'

I need to have one query that returns 3 columns: TotalEmpCount, USEmpCount, UKEmpCount.

I need this query in T-SQL as well as Linq format

    figured it out myself:

    SELECT  (
        SELECT COUNT(*) 
FROM Employees as e
WHERE HomePhone <> ''
        ) AS TotalEmpCount,
        (
        SELECT COUNT(*)
FROM Employees as e
INNER JOIN Orders as o ON e.EmployeeID=o.EmployeeID
WHERE e.HomePhone <> '' AND e.Country='US' AND o.OrderDate BETWEEN '11/01/2011' AND GETDATE()
        )  AS USEmpCount,
        (
        SELECT COUNT(*)
FROM Employees as e
INNER JOIN Orders as o ON e.EmployeeID=o.EmployeeID
WHERE HomePhone <> '' AND Country ='UK' AND o.OrderDate BETWEEN '01/01/2011' AND '12/31/2012'
        )  AS UKEmpCount
