如何根据最大值创建列表？

Question

我想创建一个列表

@list = [1], [2], ... ,[8]

基于在sql server中包含数值MAX = 8的变量。

我该怎么办？

Answer 1

一种方法

DECLARE @var INT = 8

DECLARE @list VARCHAR(MAX)

;WITH C AS
(
  SELECT ROW_NUMBER() OVER (ORDER BY [object_id]) AS n
  FROM sys.all_objects 
)
SELECT @list =
STUFF((SELECT ', [' + CAST(n AS VARCHAR(5)) + ']' AS [text()]
        FROM  
        (SELECT n FROM C WHERE n <= @var
         ) x
        For XML PATH ('')), 1, 1, '')

SELECT @list
