If today is 10 JULY 2015 then what I need is a record set in SQL Server which has the following records
6 JULY 2015
29 JUNE 2015
22 JUNE 2015
15 JUNE 2015
8 JUNE 2015
1 JUNE 2015
25 MAY 2015
Try this
;WITH dates AS
(
SELECT CONVERT(datetime,cast(month(getdate())-2 as varchar(2))+'/'+cast(day(getdate()) as varchar(2))+'/'+ cast(year(getdate()) as varchar(4))) as Date,' ' as eid
UNION ALL
SELECT DATEADD(d,1,[Date]),' ' as eid
FROM dates
WHERE DATE < GETDATE()
)
select datename(DD,dates.date)+' '+datename(MM,dates.date)+' '+ datename(YYYY,dates.date) from dates
where datename(dw,dates.date) = 'Monday'
With the following expression you get the last Monday:
CAST(GETDATE()-(@@DATEFIRST-1+DATEPART(weekday,GETDATE())) % 7+1 AS DATE)
Here we use @@DATEFIRST and DATEPART(weekday,...) to find the last MONDAY.
Then you should generate 8 (two months) rows sequence of days each of them -7 days prior the next. Here I've used CTE but you can use UNION or TOP 8 rows from existing (system or user) in your DB table to generate 8 rows.
;WITH CT(n) AS
(
SELECT 0
UNION ALL
SELECT n+1 FROM CT WHERE n < 7
)
SELECT DATEADD(DAY,-n*7,
CAST(GETDATE()-
(@@DATEFIRST-1+DATEPART(weekday,GETDATE())) % 7+1 AS DATE)) as DT
FROM CT ORDER BY n
