ERP系统中：生日提醒-农历版

在实施ERP的时候，有不少企业都提出他们那边过生日基本是根据农历来，故做了一个出来，其他同行也可以借鉴下，可以将农历生日提醒内置到数据库中，以方便其他实施员直接使用。以下是制作过程：

 

第一步：创建农历日期函数

CODE:
USE [AIO7_COST_FC]
GO
/****** Object:  UserDefinedFunction [dbo].[fn_GetLunar]    Script Date: 07/06/2015 17:23:15 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE  FUNCTION  [dbo].[fn_GetLunar](@solarDay  DATETIME)          
RETURNS  datetime          
AS          
BEGIN          
  DECLARE  @solData  int          
  DECLARE  @offset  int          
  DECLARE  @iLunar  int          
  DECLARE  @i  INT            
  DECLARE  @j  INT            
  DECLARE  @yDays  int          
  DECLARE  @mDays  int          
  DECLARE  @mLeap  int          
  DECLARE  @mLeapNum  int          
  DECLARE  @bLeap  smallint          
  DECLARE  @temp  int                
  DECLARE  @YEAR  INT            
  DECLARE  @MONTH  INT          
  DECLARE  @DAY  INT                      
  DECLARE  @OUTPUTDATE  DATETIME            
  --保证传进来的日期是不带时间        
  SET  @solarDay=cast(@solarDay  AS  char(10))          
  SET  @offset=CAST(@solarDay-'1900-01-30'  AS  INT)                
  --确定农历年开始        
  SET  @i=1900          
  --SET  @offset=@solData          
  WHILE  @i<2050  AND  @offset>0          
  BEGIN          
      SET  @yDays=348          
      SET  @mLeapNum=0          
      SELECT  @iLunar=dataInt  FROM  SolarData  WHERE  yearId=@i            
      --传回农历年的总天数        
      SET  @j=32768          
      WHILE  @j>8          
      BEGIN          
          IF  @iLunar  &  @j  >0          
              SET  @yDays=@yDays+1          
          SET  @j=@j/2          
      END          
      --传回农历年闰哪个月 1-12  ,  没闰传回 0          
      SET  @mLeap  =  @iLunar  &  15          
      --传回农历年闰月的天数 ,加在年的总天数上        
      IF  @mLeap  >  0          
      BEGIN          
          IF  @iLunar  &  65536  >  0          
              SET  @mLeapNum=30          
          ELSE            
              SET  @mLeapNum=29          
          SET  @yDays=@yDays+@mLeapNum          
      END                
      SET  @offset=@offset-@yDays          
      SET  @i=@i+1          
  END                  
  IF  @offset  <=  0          
  BEGIN          
      SET  @offset=@offset+@yDays          
      SET  @i=@i-1          
  END          
  --确定农历年结束            
  SET  @YEAR=@i          
  --确定农历月开始        
  SET  @i  =  1          
  SELECT  @iLunar=dataInt  FROM  SolarData  WHERE  yearId=@YEAR      
  --判断那个月是润月        
  SET  @mLeap  =  @iLunar  &  15          
  SET  @bLeap  =  0          
  WHILE  @i  <  13  AND  @offset  >  0          
  BEGIN          
      --判断润月        
      SET  @mDays=0          
      IF  (@mLeap  >  0  AND  @i  =  (@mLeap+1)  AND  @bLeap=0)          
      BEGIN--是润月        
          SET  @i=@i-1          
          SET  @bLeap=1          
          --传回农历年闰月的天数        
          IF  @iLunar  &  65536  >  0          
              SET  @mDays  =  30          
          ELSE            
              SET  @mDays  =  29          
      END          
      ELSE          
      --不是润月        
      BEGIN          
          SET  @j=1          
          SET  @temp  =  65536            
          WHILE  @j<=@i          
          BEGIN          
              SET  @temp=@temp/2          
              SET  @j=@j+1          
          END          
          IF  @iLunar  &  @temp  >  0          
              SET  @mDays  =  30          
          ELSE          
              SET  @mDays  =  29          
      END                
      --解除闰月    
      IF  @bLeap=1  AND  @i=  (@mLeap+1)      
          SET  @bLeap=0      
      SET  @offset=@offset-@mDays          
      SET  @i=@i+1          
  END          
        
  IF  @offset  <=  0          
  BEGIN          
      SET  @offset=@offset+@mDays          
      SET  @i=@i-1          
  END            
  --确定农历月结束            
  SET  @MONTH=@i            
  --确定农历日结束            
  SET @DAY=@offset    
SET @OUTPUTDATE=CAST(@Year AS char(4))
        + RIGHT('0' + CAST(@Month AS varchar(2)), 2)
        + RIGHT('0' + CAST(@Day AS varchar(2)), 2)
        RETURN  @OUTPUTDATE  
END
GO

 

第二步：生成公历/农历对照表

CODE:
SELECT convert(char(10),dateadd(d,number,'2015-1-1'),23) AS GL,
       --公历

       dbo.fn_GetLunar(dateadd(d,number,'2015-1-1')) AS NL --农历
INTO LunarCalenderContrastTable --公历农历对照表
FROM master..spt_values
WHERE TYPE='p'

 

第三步：根据身份证提取员工公历生日，并转化为农历生日以及今年农历生日对应的公历，此查询的列是为滚动字幕准备。

CODE:
SELECT NULL,
       'O',
       EmpName+'，在你生日来临之际，祝你生日快乐，健康幸福！',
               Convert(varchar(10), Getdate(), 120),
               Convert(varchar(10),  cast(T1.GL AS DATETIME)+3, 120),
               '系统',
               Cast(SubString(IDCard,7,8) AS DateTime) AS '身份证生日' --,DateDiff(Year,Cast(SubString(IDCard,7,8) as DateTime),GetDate())AS '年龄'

                                                                ,
                                                                dbo.fn_GetLunar1(Cast(SubString(IDCard,7,8) AS DateTime)) AS '农历出生日期',
                                                                --DateAdd(Year,DateDiff(Year,Cast(SubString(IDCard,7,8) as DateTime),GetDate()),Cast(SubString(IDCard,7,8) as DateTime)) as '本年阳历生日',

                                                                Cast(Cast(SubString(dbo.fn_GetLunar1(Cast(SubString(IDCard,7,8) AS DateTime)),1,4)  AS INT) +Cast(DateDiff(YEAR,Cast(SubString(IDCard,7,8) AS DateTime),GetDate()) AS INT) AS NVARCHAR)+ Cast(SubString(dbo.fn_GetLunar1(Cast(SubString(IDCard,7,8) AS DateTime)),5,4) AS NVARCHAR) AS '今年农历生日' ,
                                                                T1.GL AS '对应的阳历'
FROM LunarCalenderContrastTable T1
LEFT JOIN HREmp T ON Cast(cast(SubString(dbo.fn_GetLunar1(Cast(SubString(IDCard,7,8) AS DateTime)),1,4)  AS INT) +Cast(DateDiff(YEAR,Cast(SubString(IDCard,7,8) AS DateTime),GetDate()) AS INT) AS NVARCHAR)+ Cast(SubString(dbo.fn_GetLunar1(Cast(SubString(IDCard,7,8) AS DateTime)),5,4) AS NVARCHAR)=T1.NL
WHERE Cast(T1.GL AS DATETIME)>GETDATE()
  AND Cast(T1.GL AS DATETIME)< GETDATE()+8
  AND T.EmpType = 'O'
  AND T.IsClose = 'N'
