Help need in Avoiding Loop

Question

Hi,
My table and data:
Create table Sample(Empid int primary key identity(1,1),EmpName varchar(50),Empsalary money,EmpDesignation varchar(30));
insert into Sample values('Jhon',8000,'Manager'),
('Smith',6000,'Lead'),
('Samuel',4000,'AccountExecutive'),
('Simson',4000,'AccountSpecialist'),
('Eric',22000,'Director'),
('Jonathan',12000,'SeniorManager')
Expected Result
select 'EmpName','Jhon','Smith','Samuel','Simson','Eric','Jonathan' union all
select 'Salary','8000','6000','4000','4000','22000','12000' union all
select 'Designation','Manager','Lead','AccountExecutive','AccountSpecialist','Director','SeniorManager'
Is it possible to do without using loop? can anyone please give me some sample query to achieve. Also 
I have 2k * 1000 reocords in my table. Is it possible to bring the data based on by passing the page size.
Thanks in Advance
loving dotnet

I got the same error. Apparently 10K is the internal maximum and you can not go beyond that (I didn't try to find the exact limit). I slightly changed the query:
IF OBJECT_ID('TempDB..#Sample', N'U') IS NOT NULL
DROP TABLE #Sample
CREATE TABLE #Sample (
Empid INT PRIMARY KEY identity(1, 1)
,EmpName VARCHAR(50)
,Empsalary MONEY
,EmpDesignation VARCHAR(30)
INSERT INTO #Sample
VALUES (
'Jhon1'
,8000
,'Manager'
'Smith2'
,6000
,'Lead'
'Samuel3'
,4000
,'AccountExecutive'
'Simson4'
,4000
,'AccountSpecialist'
'Eric5'
,22000
,'Director'
'Jonathan6'
,12000
,'SeniorManager'
) -- 6 rows
INSERT INTO #Sample (
EmpName
,Empsalary
,EmpDesignation
SELECT EmpName = a.EmpName + CAST(ROW_NUMBER() OVER (
ORDER BY f.Empid
,e.Empid
