sqlserver年月日转汉字大写

Posted 2020-10-13 jiafeng

也是今天sql群里有人问，看起来这个问题挺简单，但是我不知道具体该怎么实现。百度了一把，找到一个高手贡献的答案，记一下。

参考链接 sql中转换中文日期

------ 配合相关函数 ------
create  function convertNumToChinese
(@instr varchar(2))
returns varchar(2)
as
begin
declare  @temStr varchar(2)
if @instr = \'1\' set @temStr =  \'一\'
if @instr =\'2\'  set @temStr =  \'二\'
if @instr =\'3\'  set @temStr =  \'三\'
if @instr =\'4\'  set @temStr =  \'四\'
if @instr =\'5\'  set @temStr =  \'五\'
if @instr =\'6\'  set @temStr =  \'六\'
if @instr =\'7\'  set @temStr =  \'七\'
if @instr =\'8\'  set @temStr =  \'八\'
if @instr =\'9\'  set @temStr =  \'九\'
if @instr =\'0\'  set @temStr =  \'零\'
return @temstr
end 

--------------实现关键--存储过程--------------------
create procedure convertDateToChinese
@vdate datetime,@ChineseDateStr varchar(50) out
as
declare @vYear varchar(20)
declare @vMonth varchar(20)
declare @vDay varchar(20)
declare @temstr varchar(100)
 
set @temstr = \'\'
set @vYear = datename(yyyy,@vdate)
--print @vyear
set @vMonth = datename(mm,@vdate)
--print @vMonth
set @vDay  = datename(dd,@vdate)
--print \'v\'+@vDay
-- 开始计算年份
set @temstr = dbo.convertNumToChinese(substring(@vYear,1,1))
set @temstr = @temstr + dbo.convertNumToChinese(substring(@vYear,2,1))
set @temstr = @temstr + dbo.convertNumToChinese(substring(@vYear,3,1))
set @temstr = @temstr + dbo.convertNumToChinese(substring(@vYear,4,1))
set @temstr = @temstr + \'年\'
 
-- 开始计算月份
if substring(@vMonth,1,1) = \'0\'
set @temstr = @temstr + dbo.convertNumToChinese(substring(@vMonth,2,1))
else
begin
 if substring(@vMonth,2,1) = \'0\'
   set @temstr = @temstr + \'十\'
 else
   set @temstr = @temstr +\'十\'+ dbo.convertNumToChinese(substring(@vMonth,2,1))
end
 
set @temstr = @temstr + \'月\'
 
-- 开始计算日期
 
if convert(int,@vDay) < 10 
  set @temstr = @temstr +  dbo.convertNumToChinese(substring(@vDay,1,1))
else
begin
  if substring(@vDay,2,1) = \'0\'
    begin 
     if  substring(@vDay,1,1)<> \'1\'
       set  @temstr = @temstr +  dbo.convertNumToChinese(substring(@vDay,1,1)) + \'十\'
      else
        set @temstr = @temstr +  \'十\'
     end
  else
    begin
     if substring(@vDay,1,1) <> \'1\'
       set @temstr = @temstr  +  dbo.convertNumToChinese(substring(@vDay,1,1)) + \'十\' + dbo.convertNumToChinese(substring(@vDay,2,1))
     else
        set @temstr = @temstr + \'十\' + dbo.convertNumToChinese(substring(@vDay,2,1))
    end
end
set @temstr = @temstr +  \'日\'  
print @temstr
set @ChineseDateStr = @temstr

调用方法：

declare @str_format varchar(30);
exec convertDateToChinese \'2017-11-08 13:30\',@str_format output
select @str_format

结果：
