how do you determine which date value should go to Brk In,Brk Out etc?

Is there a column to determine order?

;with cte as
(select studentNo, Name, Date, Time, seq = row_number() over (partition by No, studentNo, Date order by Time from table1)
select No, StudentNo, Date, TimeIn = max(case when seq = 1 then time), BrkOut = max(case when seq = 2 then time), BrkIn = max(case when seq = 3 then time), TimeOut = max(case when seq = 4 then time)
group by No, StudentNo, Date

But as visakh16 suggests there will be a lot more to this.

Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

Hi visakh16 and nigelrivett,

Thanks guys for your suggestions. This are the DATA VALUEs and its equivalent time, which i need from TABLE1, then i find it difficult to insert this DATA VALUEs to TABLE2 as shown below which will be sorted by DATE.

---Data value ---
TimeIn = 06:00-11:59
BrkOut = 12:00-12:59
BrkIn = 12:00-12:59
TimeOut = 13:00-21:00

---Table1---

No----StudentNo----Name-----------Date/Time
1----- 101-------Paula-------2012/07/16 08:00:00
2----- 101-------Paula-------2012/07/16 12:15:00
3----- 101-------Paula-------2012/07/16 12:44:00
4----- 101-------Paula-------2012/07/16 18:00:00
5----- 133-------Latina------2012/08/16 08:30:00
6----- 133-------Latina------2012/08/16 12:25:00
7----- 133-------Latina------2012/08/16 12:49:00
8----- 133-------Latina------2012/08/16 18:30:00

I wish to come up with this result, hope you guys can help me. Thanks

---Table 2---

StudentNo-----Name---------Date----------TimeIn------BrkOut-------BrkIn------TimeOut
101--------Paula------2012/07/16------08:00:00----12:15:00----12:44:00----18:00:00
133-------Latina------2012/08/16------08:30:00----12:25:00----12:49:00----18:30:00

[code]
SELECT StudentNo,Name,DATEADD(dd,DATEDIFF(dd,0,[Date/Time]),0) AS [Date],
MAX(CASE WHEN Rn=1 THEN CONVERT(time,[Date\Time]) END) AS TimeIn,
MAX(CASE WHEN Rn=2 THEN CONVERT(time,[Date\Time]) END) AS BrkOut,
MAX(CASE WHEN Rn=3 THEN CONVERT(time,[Date\Time]) END) AS BrkIn,
MAX(CASE WHEN Rn=4 THEN CONVERT(time,[Date\Time]) END) AS TimeOut
FROM
(
SELECT ROW_NUMBER() OVER (PARTITION BY StudentNo,Name,DATEADD(dd,DATEDIFF(dd,0,[Date/Time]),0) ORDER BY [Date\time]) AS Seq,
*
FROM Table
)t
GROUP BY StudentNo,Name,DATEADD(dd,DATEDIFF(dd,0,[Date/Time]),0)
[/code]
