sql存储过程获取汉字拼音头字母函数存储过程获取汉字拼音头字母函数
sql存储过程获取汉字拼音头字母函数,需要的朋友可以参考下。
复制代码 代码如下:
--函数
CREATE function fn_GetPy(@str nvarchar(4000))
returns nvarchar(4000)
--WITH ENCRYPTION
as
begin
declare @intLenint
declare @strRetnvarchar(4000)
declare @temp nvarchar(100)
set @intLen = len(@str)
set @strRet = ''
while @intLen > 0
begin
set @temp = ''
select @temp = case
when substring(@str,@intLen,1) >= '帀' then 'Z'
when substring(@str,@intLen,1) >= '丫' then 'Y'
when substring(@str,@intLen,1) >= '夕' then 'X'
when substring(@str,@intLen,1) >= '屲' then 'W'
when substring(@str,@intLen,1) >= '他' then 'T'
when substring(@str,@intLen,1) >= '仨' then 'S'
when substring(@str,@intLen,1) >= '呥' then 'R'
when substring(@str,@intLen,1) >= '七' then 'Q'
when substring(@str,@intLen,1) >= '妑' then 'P'
when substring(@str,@intLen,1) >= '噢' then 'O'
when substring(@str,@intLen,1) >= '拏' then 'N'
when substring(@str,@intLen,1) >= '嘸' then 'M'
when substring(@str,@intLen,1) >= '垃' then 'L'
when substring(@str,@intLen,1) >= '咔' then 'K'
when substring(@str,@intLen,1) >= '丌' then 'J'
when substring(@str,@intLen,1) >= '铪' then 'H'
when substring(@str,@intLen,1) >= '旮' then 'G'
when substring(@str,@intLen,1) >= '发' then 'F'
when substring(@str,@intLen,1) >= '妸' then 'E'
when substring(@str,@intLen,1) >= '咑' then 'D'
when substring(@str,@intLen,1) >= '嚓' then 'C'
when substring(@str,@intLen,1) >= '八' then 'B'
when substring(@str,@intLen,1) >= '吖' then 'A'
else rtrim(ltrim(substring(@str,@intLen,1)))
end
--对于汉字特殊字符，不生成拼音码
if (ascii(@temp)>127) set @temp = ''
--对于英文中小括号，不生成拼音码
if @temp = '(' or @temp = ')' set @temp = ''
select @strRet = @temp + @strRet
set @intLen = @intLen - 1
end
return lower(@strRet)
end
go
--调用
select dbo.fn_getpy('张三')
--返回：zs
答！： 2:
取汉字拼音首字母的存储过程
Create function fun_getPY ( @str nvarchar(4000) )
returns nvarchar(4000)
as
begin
declare @word nchar(1),@PY nvarchar(4000)
set @PY=''
