然后是汉字转拼音首字母的，第一次还真用了这个函数，不过后来才发现不是自己需要的，但以后还要用到，所以一并记录下来：

create function fun_getPY(@str nvarchar(4000)) 
returns nvarchar(4000)

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

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 (

end

对了，汉字转拼音的那个function的alert最好改成create，反正我是用create来完成的，后面的内容当然是不需要的，那两个go go的内容。希望下次看到还能用到并理解吧，上次的SQL全角转半角的函数就忘了不会用了，唉。
