I have a table containing a field of dates + a field named WeekDayID (sun=0, mon=1, tue=2, wed=3, thu=4, fri=5, sat=6) + some other field (not important to mention), and I need two reports:
1.based on month
2.based on week

I have done the report number 1

my question is HOW CAN I ACHIEVE report 2, I need something that gives me this:

let’s say we have dates from 2001/01/01 to 2001/01/31

I want to get all days grouped by week for example if 2001/01/01 is Sunday i want groups like:

1st week : 2001/01/01 – 2001/01/02 – … – 2001/01/07
2nd week : 2001/01/08 – … – 2001/01/14
3rd week : 2001/01/15 – … – 2001/01/21
4th week : 2001/01/22 – … – 2001/01/28
5th week : 2001/01/29 – 2001/01/30 – 2001/01/31

    For the week number you can use the Datepart function with the value ‘ww’ for the first parameter:

    SELECT Datepart(ww, myDate) FROM myTable

    For the date range, you can do some math tricks: Substract to your date the weekday to get the first day of the week:

    SELECT DateAdd(day, - DatePart(weekday, myDate), myDate) Week_Start
from myTable

    here you have a link to the DatePart function:
