Question

I wanted to get the week from the given date, for this I tried with the DATENAME function to get the WEEK like,

 Select DateName(WEEK,'2012-03-09')

am getting the output as 10. I want to get the starting date and ending date of this week like, 2012-03-04 to 2012-03-10 Is it possible?

Answer 1

Do something like this:

DECLARE @MyDate Date = '2012-03-09';

-- This gets you the SUNDAY of the week your date falls in...
SELECT DATEADD(DAY, -(DATEPART(WEEKDAY, @MyDate) - 1), @MyDate);

-- This gets you the SATURDAY of the week your date falls in...
SELECT DATEADD(DAY, (7 - DATEPART(WEEKDAY, @MyDate)), @MyDate);

-- This will show the range as a single column
SELECT
  CONVERT(NVarChar, DATEADD(DAY, -(DATEPART(WEEKDAY, @MyDate) - 1), @MyDate))
  + ' through ' +
  CONVERT(NVarChar, DATEADD(DAY, (7 - DATEPART(WEEKDAY, @MyDate)), @MyDate));
