使用CTE生成辅助表(数字或时间)等

数字辅助表：

 

DECLARE @start_digital INT = 0,
        @end_digital INT = 9

;WITH Digital_Rangs(Digital) 
AS
(
    SELECT  @start_digital 
    UNION ALL
    SELECT [Digital] = [Digital] + 1
    FROM [Digital_Rangs]
    WHERE [Digital] < @end_digital
)

SELECT [Digital] FROM [Digital_Rangs] Option (MaxRecursion 0);
