Hi,
I am having data in a table in the form

L_Limit    U_Limit       Asset      Timestamp
10             20             1000      2013-06-14 16:52:57.910
20             30             1500      2013-06-14 16:52:57.910
30             40             2200      2013-06-14 16:52:57.910
10             20             2000      2013-06-15 18:52:57.910
20             30             1300      2013-06-15 18:52:57.910
30             40             2100      2013-06-15 18:52:57.910
10             20             3000      2013-06-16 18:20:27.910
20             30             2300      2013-06-16 18:20:27.910
30             40             1100      2013-06-16 18:20:27.910

i.e. a Job appends data(i.e. value of asset) for same ranges 10 to 20,20 to 30 and 30 to 40 everyday when I run a job schedule. This data will be stored on a daily basis for months.

Also, this limit range is also saved separately in 'Range' table as columns:

 Lower_Limit   Upper_Limit
10              20
20              30
30              40

My requirement is to show this data in this format in a view to show asset value on 3 days i.e. Today, before 7 days, before 30 days:

L_Limit  U_Limit  Asset_Today   Asset_Before7Days  Asset_Before30Days
10        20   
20        30
30        40

Please suggest how can I get data in this format?
Thanks in advance.

Assuming that you want to show asset value from 6/9/2013 under Asset_Before7Days column and asset value from 5/17/2013 under Asset_Before30Days column if today is 6/16/2013
Is this what you want?

[CODE]

DECLARE @QDate DATE = Getdate();

SELECT L_Limit, U_Limit, MAX(CASE WHEN (CAST([TimeStamp] as DATE) = @QDate) THEN Asset END) AS TodaysAsset,
MAX(CASE WHEN (CAST([TimeStamp] as DATE) = DATEADD(Day, -7, @QDate)) THEN Asset END) AS AssetWeekAgo,
MAX(CASE WHEN (CAST([TimeStamp] as DATE) = DATEADD(Day, -30, @QDate)) THEN Asset END) AS AssetMonthAgo
FROM @TABLE1 GROUP BY L_Limit, U_Limit;

-- OR

SELECT T.L_Limit, T.U_Limit, MAX(CASE WHEN (CAST([TimeStamp] as DATE) = @QDate) THEN Asset END) AS TodaysAsset,
MAX(CASE WHEN (CAST([TimeStamp] as DATE) = DATEADD(Day, -7, @QDate)) THEN Asset END) AS AssetWeekAgo,
MAX(CASE WHEN (CAST([TimeStamp] as DATE) = DATEADD(Day, -30, @QDate)) THEN Asset END) AS AssetMonthAgo
FROM @TABLE1 T INNER JOIN @RangeTable R ON (T.L_Limit = R.L_Limit and T.U_Limit = R.U_Limit) GROUP BY T.L_Limit, T.U_Limit

[/CODE]
