Hello all, I have a sql table with basic employee details as below

table: tblEmployees
EmpID     Name       Contact     Sex
100       John       55555        M
200       Kate       44444        F
300       Sam        88888        M

I would like to get my query result as follows of a particular employee where EmpID=200

Col1         Col2
EmpID        200
Name         Kate
Sex          F

What I have tried:

i have tried playing with pivot and unpivot , but filed to achieve the same. Any help will be highly appreciated.

UNPIVOT is what you need.
SELECT Col2, Col1 FROM (SELECT * FROM tblEmployees WHERE Empid = 200) a
UNPIVOT(Col1 FOR Col2 IN (EmpID, Name, Sex)) AS unp

Do we need to cast if the columns are of multi-data types? Example: Employee Id is int and the rest of the columns are of varchar type.

Yes. Think about it: it is returning a table, which is a set of rows and columns. A column can only contain data of a single type so if you want to "mix and match" you need to cast to ensure they are the same.
Replace "*" in the SELECT list with the columns you want, and use CAST to convert them - you will need to name the "new" columns or it will rightly complain!

Good evening. I had a table with a Unique Identifier, Varchar, int, and DateTime. I have used the below command for the output. I have tested in SQL Server Mgt Studio.

SELECT [ColumnName], [ColumnValue]
FROM Health
('Id', cast(Id as varchar(50))),
('Name', [Name]),
('Health Parameter1', cast(HealthParameter1 as varchar(10))),
('Health Parameter2', cast(HealthParameter2 as varchar(10))),
('Received At', cast(ReceivedAt as varchar(50)))
) c ([ColumnName], [ColumnValue])
where Id = 'F84BBA87-6241-4E0A-4F42-08D7C291F501';

Yes, this answered my question.
declare @table table ( id int identity(1,1), EMPID varchar(5)  , [Name] varchar(20), contact Varchar(20) , gender char(10))

insert into @table ( empid,  [name], contact, gender) values ('100','John',       '55555',        'M')
insert into @table ( empid,   [name], contact, gender) values ('200','Kate',       '44444',        'F')
insert into @table ( empid,    [name], contact, gender) values ('300','Sam',       '44444',        'M')

declare @kvpTable table (keyVal varchar(20), val varchar(20) , objectKey int )

declare @min int = 0, @max int = 0

select @min = min(id)  , @max = max(id) from @table 
declare @name varchar(20) 
declare @contact varchar(20)
declare @mf char(1)
declare @emp varchar(8)

while @min <= @max
select @emp= empid,  @name = [name], @contact = contact , @mf = gender  from @table where id = @min 

insert into @kvpTable 
select 'EmpID', @emp , @min
select 'name', @name, @min
select 'contact', @contact, @min
select 'gender' ,@mf , @min

set @min = @min + 1

select * from @kvpTable

Rarely, very rarely, do you ever need to use a loop in set based languages such as SQL
