Iam unable to convert this in required out put.
My Table Consist of following data
TimeId -- EmpId -- weekStartingDate -- Totalhours
1 -- 100 -- 8/1/2010 -- 42:00
2 -- 100 -- 8/8/2010 -- 24:00
3 -- 100 -- 8/15/2010 -- 24:00
4 -- 100 -- 8/22/2010 -- 42:00
5 -- 101 -- 8/1/2010 -- 24:00
6 -- 101 -- 8/8/2010 -- 42:00
I need to generate output,
Reports like this
Scheduled Hours | 8/1/2010 | 8/8/2010 | 8/15/2010 | 8/22/2010
less than 24 hrs -- 50% | 50% | 50% | 0%
b/w 24 and 48 -- 50% | 50% | 0% | 50%
more than 48 hrs -- 0% | 0% | 0% | 0%
Additional Information
No of employees is per week(i.e calculate percentage of employees scheduled less than 24hrs....)
Date Column - SUnday date.(i.e sunday to saturday)
Month -user will select excel file data of every week uploads it to database.
I will select particular date from date control(select only date which falls on sunday).
If i select this sunday date i want reports for last 4 weeks,3 weeks,2 weeks and this week.
Everytime when user selects date we need to generate reports for last 4,3,2 from the selected sunday date.

Your question is not really clear...

What do you mean by "If this much is sufficient then its ok else..."??? What determines "sufficient"?

Also, please clarify what SQL Server version you're using. It'll make a huge difference regarding the possible solutions.

Finally, please provide teable def and sample data in a ready to use format including your expected result based on the sample data as described in the first link in my signature.

Sorry,its sql server 2000.

I hv corrected it.

CREATE TABLE [tblTest] (

[TimeId] [int] NOT NULL ,

[EmpId] [int] NOT NULL ,

[weekStartingDate] [datetime] NOT NULL ,

[Totalhours] [decimal](18, 2) NOT NULL

) ON [PRIMARY]

GO

Just someone convert given sample data to output.

How about taking a look at the CrossTab article referenced in my signature?

It might help you to get the data pivoted.

I'm not sure who you refer to with "Just someone convert given sample data to output."...

It seems like you didn't find the time to read and follow the advice given in the link I pointed you at.

So, all I can say is "Just someone to read that CrossTab article and modify it to your needs."

Hi,

Kindly ignore my language.I never meant that,I am not trying and someone just help me.

I am trying to follow the link u gave.

What I meant was even if someone convert the input table data in desired output then its more than enough.

I just want one example in pivot/cross tab thru this example.Then may be I understand this for the rest of my life.

This should get you started.

Things still left to to:

1. convert to %, and summarize.

2. probably want this to be dynamic.

Please read the Cross-Tabs and Pivot Tables, Part 1 and Part 2 links in my signature. The part 2 will help in making this dynamic.

-- See how you start off by actually creating a table and then

-- inserting the data into it? Your doing this makes it a lot easier

-- See http://www.sqlservercentral.com/articles/Best+Practices/61537/

-- for more details on how to do all of this.

FROM @test-2) t1

GROUP BY [Hours]

Thanks.

Data is repeating.If I run the query as it is then,

"b/w 24 and 48" is repeating,rather it should show its sum.

Please check my query,only thing is that I am unable to pivot it.

DECLARE @test-2 TABLE (TimeID int, EmpID int, weekStartingDate datetime, TotalHours decimal(5,2));

INSERT INTO @test-2

SELECT 1, 100, '8/1/2010', 42.13 UNION ALL

SELECT 2, 100, '8/8/2010', 24.00 UNION ALL

SELECT 3, 100, '8/15/2010',23.00 UNION ALL

SELECT 4, 100, '8/22/2010',49.00 UNION ALL

SELECT 5, 101, '8/1/2010', 24.00 UNION ALL

SELECT 6, 101, '8/8/2010', 42.00 union all

SELECT 7, 101, '8/8/2010', 13.00

SELECT weekstartingdate ,

Count(Case When Totalhours<=24 Then empid end) as LessThan24hrs,

Count(Case when Totalhours>24 and Totalhours<=48 Then empid end) as bw24and48,

Count(Case when Totalhours>48 Then empid end) as Morethan48hrs

FROM @test-2

GROUP BY weekstartingdate

I know what your next question will be but make sure that this is what you want at this stage first...

DECLARE @test-2 TABLE (TimeID int, EmpID int, weekStartingDate datetime, TotalHours decimal(5,2));

INSERT INTO @test-2

SELECT 6, 101, '8/8/2010', 42.00 UNION ALL

SELECT 7, 101, '8/8/2010', 13.00

;

SELECT CASE TimeSlot

WHEN 1 THEN 'LessThan24hrs'

END AS [Scheduled Hours],

SUM(CASE WHEN WeekStartingDate = '20100801' THEN TheCount ELSE 0 END) AS '20100801',

SUM(CASE WHEN WeekStartingDate = '20100815' THEN TheCount ELSE 0 END) AS '20100815',

SUM(CASE WHEN WeekStartingDate = '20100822' THEN TheCount ELSE 0 END) AS '20100822'

FROM ( --=== Preaggregate the data

SELECT WeekStartingDate, TimeSlot, COUNT(*) AS TheCount

FROM

( --=== Classify the hours for a given time slot to create groupable rows from

SELECT WeekStartingDate,

CASE

WHEN TotalHours <=24 THEN 1

WHEN TotalHours >24 AND TotalHours <=48 THEN 2

END AS TimeSlot

FROM @test-2

) classify

GROUP BY WeekStartingDate, TimeSlot

) preagg

GROUP BY TimeSlot

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
