SQL根据两个日期生成年、月、日

 1 DECLARE @beginTime DATETIME, @endTime DATETIME
 2 SET @beginTime ='2019-03-01'
 3 SET @endTime ='2019-12-31 23:59:59'
 4 
 5 --1.生成年份
 6 SELECT CONVERT(VARCHAR(4),DATEADD(YEAR,number,@beginTime),120) AS 年
 7 FROM master..spt_values 
 8 WHERE type='p' AND DATEADD(YEAR,number,@beginTime)<=@endTime
 9 
10 --2.生成月份
11 SELECT CONVERT(VARCHAR(7),DATEADD(MONTH,number,@beginTime),120) AS 月份
12 FROM master..spt_values 
13 WHERE type='p' AND DATEADD(MONTH,number,@beginTime)<=@endTime
14 
15 --3.生成日期
16 SELECT CONVERT(VARCHAR(10),DATEADD(DAY,number,@beginTime),120) AS 日期
17 FROM master..spt_values 
18 WHERE type='p' AND DATEADD(DAY,number,@beginTime)<=@endTime
