Answer 1

Jeśli potrzebujesz tabela:

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

SELECT * FROM Sec 
OPTION(MAXRECURSION 0) 

Jeśli potrzebujesz jeden ciąg:

;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) 

Answer 2

poniższe zapytanie wybiera wartości od 0 do 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);
