3.创建公历，农历详细比照表
公历农历详细比照表
1 CREATE TABLE [dbo].[SolarLunarData](
2 [RecID] [int] IDENTITY(1,1) NOT NULL,
3 [SolarDate] [datetime] NOT NULL,
4 [LunarDate] [varchar](10) NOT NULL,
5 CONSTRAINT [PK_SolarLunarData] PRIMARY KEY CLUSTERED
6 (
7 [SolarDate] ASC
8 )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
9 ) ON [PRIMARY]
10
11 GO
4.生成数据于公历农历详细比照表
导入数据至公历农历比照表
1 TRUNCATE TABLE SolarLunarData
2 GO
3 DECLARE @i INT
4 SET @i=0
5 WHILE @i<3000
6 BEGIN
7 INSERT INTO SolarLunarData(SolarDate,LunarDate)
8 SELECT CONVERT(CHAR(10),DATEADD(d,@i,'2010-01-01'),23),
9 dbo.fn_GetLunar(DATEADD(d,@i,'2010-01-01'))
10 SET @i=@i+1
11 END
5.创建农历获取公历函数
农历获取公历日期函数
1 IF object_id('fn_GetSolar') IS NOT NULL
2 DROP FUNCTION fn_GetSolar
3 GO
4 CREATE FUNCTION dbo.fn_GetSolar(@day VARCHAR(10))
5 RETURNS DATETIME
6 AS
7 BEGIN
8 RETURN(SELECT SolarDate FROM SolarLunarData WHERE LunarDate=@day)
9 END
10 GO
