用cte创建while循环

Question

如何从while循环中创建sql server cte
这样的循环

  declare @ind as int
  declare @code as nvarchar
  set @ind  = 0
   while @ind < 884
  begin
    select @ind  = @ind  + 1
    --here execute Procedure 
        --and set return value to variable 
    set @code = cast (@ind   as nvarchar)
  end

Answer 1

如果需要表：

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

SELECT * FROM Sec
OPTION(MAXRECURSION 0)

如果您需要一个字符串：

;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)
