使用它：

declare @start int
declare @end int
set @start = 5;
set @end = 10;

;with ranges AS
(
    SELECT 
        @start as val
    UNION ALL
    SELECT 
        val + 1
    FROM   ranges
    WHERE  val+1 <= @end
)
Select distinct 
       substring((select ','+convert(varchar, ranges.val) as [text()]
                  from   ranges
                  order by 
                         ranges.val
                  for XML path ('')),2, 1000)
from   ranges
