Question

how to create sql server cte from a while loop
my loop like this

  declare @code as nvarchar
  set @ind  = 0
   while @ind < 884
           


        

Answer 1

Below query selects values from 0 to 884:

;WITH T(Num)AS
(
    SELECT 0 
    UNION ALL
    SELECT Num+1 FROM T WHERE T.Num < 884
)SELECT Num FROM T 
OPTION (MAXRECURSION 0);

Answer 2

If you need table:

;WITH Sec(Number) AS 
(
    SELECT 0 AS Number
    UNION ALL
    SELECT Number + 1
    FROM Sec
    WHERE Number < 884
) 

SELECT * FROM Sec
OPTION(MAXRECURSION 0)

If you need one string:

;WITH Sec(Number) AS 
(
    SELECT 0 AS Number
    UNION ALL
    SELECT Number + 1
    FROM Sec
    WHERE Number < 884
) 

SELECT STUFF(a.[Str], 1, 1, '')
FROM
(
    SELECT (SELECT ',' + CAST(Number AS NVARCHAR(3)) 
    FROM Sec
    FOR XML PATH(''), TYPE
    ).value('.','varchar(max)') AS [Str] 
) AS a
OPTION(MAXRECURSION 0)
