1、下面这个方法是中文转为拼音首字母方法
create function dbo.fun_getPY(@str nvarchar(255))
returns nvarchar(50)as
begin
declare @word nchar(1),@PY nvarchar(50)
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'
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 'O',N'沤'
union all select 'P',N'曝'
union all select 'Q',N'囕'
union all select 'R',N'鶸'
union all select 'S',N'蜶'
union all select 'T',N'箨'
union all select 'W',N'鹜'
union all select 'X',N'鑂'
union all select 'Y',N'韵'
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
GO
2、调用方法
update Price set PY_CODE = dbo.fun_getPY(ITEM_NAME)
PY_CODE 为拼音首字母字段，ITEM_NAME为需要转为拼音首字母的字段
