Prueba esto:
DECLARE @startDate DATETIME
DECLARE @currentDate DATETIME
DECLARE @numberOfWeeks INT
DECLARE @dates TABLE(
StartDate DateTime,
EndDate DateTime
)
SET @startDate = GETDATE()--'2012-01-01' -- Put whatever you want here
SET @numberOfWeeks = 8 -- Choose number of weeks here
SET @currentDate = @startDate
while @currentDate < dateadd(week, @numberOfWeeks, @startDate)
begin
INSERT INTO @Dates(StartDate, EndDate) VALUES (@currentDate, dateadd(day, 6, @currentDate))
set @currentDate = dateadd(day, 7, @currentDate);
end
SELECT * FROM @dates
Esto le dará algo como esto:
StartDate EndDate
21/03/2013 11:22:46 27/03/2013 11:22:46
28/03/2013 11:22:46 03/04/2013 11:22:46
04/04/2013 11:22:46 10/04/2013 11:22:46
11/04/2013 11:22:46 17/04/2013 11:22:46
18/04/2013 11:22:46 24/04/2013 11:22:46
25/04/2013 11:22:46 01/05/2013 11:22:46
02/05/2013 11:22:46 08/05/2013 11:22:46
09/05/2013 11:22:46 15/05/2013 11:22:46
O puede modificar la selección final si no desea el componente de tiempo, así:
SELECT CONVERT(VARCHAR, StartDate, 103), CONVERT(VARCHAR, EndDate, 103) FROM @dates
