Using a cursor with a CTE

Question

I need a cursor for the below query so I can loop through to fetch/update/insert some other data. Can somebody help me with this?

DECLARE @FROMDATE DATETI

It is fine to use @ in a cursor name but the syntax you are using is wrong.

DECLARE @adate DATETIME
DECLARE @FROMDATE DATETIME
DECLARE @TODATE DATETIME

SELECT @FROMDATE = getdate()

SELECT @TODATE = getdate() + 7

DECLARE @weekdates CURSOR;

SET @weekdates = CURSOR FOR
WITH DATEINFO(DATES)
     AS (SELECT @FROMDATE
         UNION ALL
         SELECT DATES + 1
         FROM   DATEINFO
         WHERE  DATES < @TODATE)
SELECT *
FROM   DATEINFO
OPTION (MAXRECURSION 0) 

OPEN @weekdates

FETCH next FROM @weekdates INTO @adate

WHILE @@fetch_status = 0
  BEGIN
      PRINT 'success'

      FETCH next FROM @weekdates INTO @adate
  END

When declared as a local @ variable the cursor is automatically closed and deallocated when the variable goes out of scope.
