sql函数：汉字转换为拼音

sql数据库
自定义一个函数
把下面代码写进去

功能是得到汉字拼音首字母

 如下：

create function fun_getPY(@str nvarchar(4000))

returns nvarchar(4000)

as

begin

declare @word nchar(1),@PY nvarchar(4000)

set @PY=''

while len(@str)>0

begin

set @word=left(@str,1)

--如果非汉字字符，返回原字符

set @PY=@PY+(case when unicode(@word) between 19968 and 19968+20901

then (select top 1 PY from (

select 'A' as PY,N'驁' as word

union all select 'B',N'簿'

union all select 'C',N'錯'

union all select 'D',N'鵽'

union all select 'E',N'樲'

union all select 'F',N'鰒'

union all select 'G',N'腂'

union all select 'H',N'夻'

union all select 'J',N'攈'

union all select 'K',N'穒'

union all select 'L',N'鱳'

union all select 'M',N'旀'

union all select 'N',N'桛'

union all select 'R',N'鶸'

union all select 'S',N'蜶'

union all select 'T',N'籜'

union all select 'W',N'鶩'

union all select 'X',N'鑂'

union all select 'Y',N'韻'

union all select 'Z',N'咗'

) T 

where word>=@word collate Chinese_PRC_CS_AS_KS_WS 

order by PY ASC) else @word end)

set @str=right(@str,len(@str)-1)

end

return @PY

end

--函数调用实例：
select dbo.fun_getPY('中华人民共和国')
结果都为：ZHRMGHG
