建立乙個查詢，執行下面的語句生成函式fn_getpy
複製** **如下:
--生成拼音首碼
create function fn_getpy(@str nvarchar(4000))
returns nvarchar(4000)
--with encryption
as begin
declare @intlen int
declare @strret nvarchar(4000)
declare @temp nvarchar(100)
set @intlen = len(@str)
set @strret = ''
while @intlen > 0
begin
set @te = ''
select @temp = case
when substring(@str,@intlen,1) >= '帀' then 'z'
when sub程式設計客棧string(@str,@intlen,1) >= '丫' then 'y'
when substring(@str,@intlen,1) >= '夕' then 'x'
when substring(@str,@intlen,1) >= '屲' then 'w'

end
--對於漢字特殊字元，不生成拼音碼
if (ascii(@temp)>127) set @temp = ''
--對於英文中小括號，不生成拼音碼
if @temp = '(' or @temp = ')' set @temp = ''
select @strret = @temp + @strret
set @intlen = @intlen - 1
end
return lower(@strret)
end
