How to Create Week

alvinford — Wed, 04 Feb 2015 14:51:50 GMT

Hi ,

Request your help to achieve this...

I have the following Data.

Year	City	StartDate	EndDate
2013	AZ	2/8/2014	15/8/2014
2013	CA	12/10/2013	1/11/2013
2013	AX	9/8/2013	22/8/2013

Would like to derive the Weeks between StartDate and End Date. The First 7 Days between StartDate and EndDate will be considered as Week1 and Next 7 Days will be Week 2 and So on for each City. The Final Output will be as below.

I have highlighted the City and Week for better understanding indicating every City has Week1 and so on..

Thank You in Advance...

12/10/2013	20/12/2013	12/10/2013	2013	CA	Week1

You can use the method described in Creating Reference Dates for Intervals.

Load Year, City, StartDate, EndDate

Div( IterNo() + 6, 7 ) as ReferenceWeek,

Date( StartDate + IterNo() – 1 ) as ReferenceDate

From SourceTable

While IterNo() <= EndDate - StartDate + 1 ;

Try this.

Dates:

LOAD * INLINE [

Year, City, StartDate, EndDate

2013, AZ, 2/8/2014, 15/8/2014

2013, CA, 12/10/2013, 1/11/2013

2014, AX, 9/8/2014, 22/8/2014

];

NOCONCATENATE

Temp1:

LOAD

date(StartDate + IterNo()-1,'DD/MM/YYYY') as Tdate,

'Week '&ceil(interval(date(StartDate + IterNo())-StartDate,'D')/7) as Week

RESIDENT Dates

WHILE date(StartDate + IterNo()) <= date(EndDate+1)

;
