此存储过程用于获取SQL Server中汉字的拼音首字母，通过遍历输入字符串并判断每个字符是否为汉字来实现。若为汉字，则查找对应的拼音首字母。

Sqlserver得到汉字拼音首字母存储过程:

create function [dbo].[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'骜' as word
               union all select 'B',N'簿'
               union all select 'C',N'错'
               union all select 'D',N'鵽'
               union all select 'E',N'樲'
               union all select 'F',N'鳆'
               union all select 'G',N'腂'

               ) 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
