SQL中有多種的函數，下面為您介紹sql中漢字轉換為拼音的函數，供您參考。數據庫中先自定義一個函數，再把下面代碼寫進去，功能是得到漢字拼音首字母：
如下：
01 |
create function fun_getPY(@str nvarchar(4000)) |
02 |
returns nvarchar(4000) |
03 |
as |
04 |
begin |
05 |
declare @word nchar(1),@PY nvarchar(4000) |
06 |
set @PY='' |
07 |
while len(@str)>0 |
08 |
begin |
09 |
set @word=left(@str,1) |
10 |
--如果非漢字字符，返回原字符 |
11 |
set @PY=@PY+(case when unicode(@word) between 19968 and 19968+20901 |
12 |
then (select top 1 PY from ( |
13 |
select 'A' as PY,N'驁' as word |
14 |
union all select 'B',N'簿' |
15 |
union all select 'C',N'錯' |
16 |
union all select 'D',N'鵽' |
17 |
union all select 'E',N'樲' |
18 |
union all select 'F',N'鰒' |
19 |
union all select 'G',N'腂' |
20 |
union all select 'H',N'夻' |
21 |
union all select 'J',N'攈' |
22 |
union all select 'K',N'穒' |
23 |
union all select 'L',N'鱳' |
24 |
union all select 'M',N'旀' |
25 |
union all select 'N',N'桛' |
26 |
union all select 'O',N'漚' |
27 |
union all select 'P',N'曝' |
28 |
union all select 'Q',N'囕' |
29 |
union all select 'R',N'鶸' |
30 |
union all select 'S',N'蜶' |
31 |
union all select 'T',N'籜' |
32 |
union all select 'W',N'鶩' |
33 |
union all select 'X',N'鑂' |
34 |
union all select 'Y',N'韻' |
35 |
union all select 'Z',N'咗' |
36 |
) T |
37 |
where word>=@word collate Chinese_PRC_CS_AS_KS_WS |
38 |
order by PY ASC) else @word end) |
39 |
set @str=right(@str,len(@str)-1) |
40 |
end |
41 |
return @PY |
42 |
end |
--函數調用實例：
select dbo.fun_getPY('中華人民共和國')
結果都為：ZHRMGHG
