CREATE TABLE #WeekTable(

YearCol INT

,WeekCol VARCHAR(9)

);

INSERT INTO #WeekTable (YearCol, WeekCol)

SELECT 2009, 'wk1' UNION ALL

SELECT 2009, 'wk31' UNION ALL

SELECT 2009, 'wk52' UNION ALL

SELECT 2010, 'wk1' UNION ALL

SELECT 2010, 'wk31' UNION ALL

SELECT 2010, 'wk52' UNION ALL

SELECT 2011, 'wk1' UNION ALL

SELECT 2011, 'wk31' UNION ALL

SELECT 2011, 'wk52'

SELECT

[Week] = CASE WHEN REPLACE(WeekCol, 'wk', '') = DATEPART(wk, CURRENT_TIMESTAMP)

THEN '0'

ELSE WeekCol

END

,*

FROM #WeekTable;

DROP TABLE #WeekTable;

Hi,

Thanks for the details but I don't have access to run these commands in our db. I can access from report end....

Means I need to use whatever tables already there in my package as I told you earlier.....I need to use Merchandise week table from my package which is having values like wk1,wk2.....wk53 for each year..

Only thing I can do is use the fucntions which is there in report level like date functions or case,if,for anything to get our output.

Thanks

You posted your question in SQL Server Development forum and you asked for sql function...

What report are you talking about? If this is SSRS report the VB.Net also has DatePart function you can use.

http://msdn.microsoft.com/en-us/library/20ee97hz(v=vs.71).aspx

=DatePart(DateInterval.WeekOfYear, Today)

Hi,

I can't execue these cmsds in our database since I don't have rights to do that. I was talking about the Cognos Reports where I have to implement this logic to run my report.

Thanks
