Using While Loop i want to insert the values into single record like this
Empid empname D1 D2 D3...D30
1 asd 2
Loop Executes second time
Empid empname D1 D2 D3...D30
1 asd 2 2
Loop Executes third time
Empid empname D1 D2 D3...D30
1 asd 2 2 1
Like this loop should update single record for the single employee... Thanks in advance

Please explain why you are doing this.
Also, you first talk about inserts, then later updates as though they are the same thing. They are not.

Yes, it does seem a strange requirement. But why would you want to use a loop, anyway?
INSERT INTO MyTable (Empid,empname,D1,D2, D3,...,D30)
VALUES (1,'asd',2,2,1,...,<Val30>)

Consider my count is 30
using while loop i am decrement it..till it reaches zero
count =30
then output should be
Empid empname D1 D2 D3...D30
1 asd 2
count =29
Empid empname D1 D2 D3...D30
1 asd 2 2
Count=28
Empid empname D1 D2 D3...D30
1 asd 2 2 1
My code is like
WHILE @Cnt>0
BEGIN
INSERT INTO #Newtemp1(EmpID,Working_Days,MainTeamID,D1,D2...Help me in this insert statement
SET @Cnt=@Cnt-1;
END;
END

WHILE loops are slow. Most people here will refuse to give you a slow solution when much faster alternatives are available. But unless we can understand what you are trying to do, we cannot do that either.
Tell us what the source is and what the desired end result is. Use code to do this rather than trying to waffle round it in English.
Use the link in my signature to understand how best to present your question so that people can understand it and provide you with working code as a solution.

You say you're going to a single record, but are you actually putting everything into one column? If so, why. That's not what a relational database management system is designed to do. Cramming everything into a single column has tons of bad implications, limitations, performance issues, etc. I'm with everyone else. Why are you doing what you're doing?

Yeah, loop is a bad idea.
I think the data represents a month (even though he's limited it to 30 )...my guess is he's trying to pivot the data
E.g.
--assuming data is for a given month
IF OBJECT_ID('tempdb..#WorkDays') IS NOT NULL DROP TABLE #WorkDays
CREATE TABLE #WorkDays ( EmpId int, EmpName varchar(20), MainTeamId int, WorkDate date )
INSERT INTO #WorkDays ( EmpId, EmpName, MainTeamId, WorkDate )
VALUES
( 1, 'ASD', 2, '2016-05-01' ),
( 1, 'ASD', 2, '2016-05-01' ),
( 1, 'ASD', 2, '2016-05-02' )
SELECT *
FROM
(
SELECT T.EmpId, T.EmpName, T.MainTeamId, Calc.WorkDateDay
FROM #WorkDays T
CROSS APPLY ( SELECT DATEPART( day, T.WorkDate ) AS WorkDateDay ) AS Calc
) D
PIVOT ( COUNT( WorkDateDay ) FOR WorkDateDay IN ( [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31] ) ) PVT

Hi, Thanks for ur reply
My requirement is like i have two tables one is Shiftscheduler (captures only when Shift and shifttype is 2 and 4 respectively) and another table is employee (captures if shift and shift type is 1 and 2 respectively)...step 1 i have to check the shift type 1 or 2..based on that i have to choose the tables then update the temp table based on the shift
Sample
Input (Choose it from date to to date)
Date Empid Shift Shifttype
1/1/2014 2424 2 4
1/2/2014 2424 2 4
1/3/2014 2424 2 4
1/4/2014 2424 1 2
Output like
Empid d1shift d1shifttype d2shift d2shifttype d3shift d3shifttype d4shift d4shifttype
2424 2 4 2 4 2 4 1 2
Please help

2424 2 4 2 4 2 4 1 2
It should process on daily basis..please suggest me any loop will do or any better sugesstion

Find the employee is in which shift and shifttype
If he is shift 1 shifttype 1then the record comes from employee table
if he is shift 2 shifttype 4 then the record comes from shiftscheduler table
For example :
I want to know the details empid : 3321 From date 1/1/2015 to 1/10/2015
1/1/2015 -- shift 1 shifttype 1
1/2/2015 -- shift 1 shifttype 1
1/3/2015 -- shift 1 shifttype 1
1/4/2015 -- shift 1 shifttype 1
Still this time record comes from employee table
now shift changes
1/5/2015 --shift 2 shifttype 4
1/6/2015 --shift 2 shifttype 4
Above 2 records comes from shiftscheduler table
Again shift changes
1/7/2015 -- shift 1 shifttype 1
1/8/2015 -- shift 1 shifttype 1
Above 2 records comes from employee table
Again Shift changes
1/9/2015 --shift 2 shifttype 4
1/10/2015 --shift 2 shifttype 4
Above 2 records comes from shiftscheduler table
My expected output is
Empid d1shift d1shifttype d2shift d2shifttype d3shift d3shifttype d4shift d4shifttype d5shift d5shifttype d6shift d6shifttype d7shift d7shifttype d8shift d8shifttype d9shift d9shifttype
3321 1 1 1 1 1 1 1 1 2 4 2 4 1 1 1 1 2 4
d1shift d1shifttype comes from 1/1/2015
d2shift d2shifttype comes from 1/2/2015
d3shift d3shifttyp comes from 1/3/2015
d4shift d4shifttype comes from 1/4/2015
d5shift d5shifttype comes from 1/5/2015
