sql函數漢字轉拼音_SQL語句提取出中文的拼音首字母

『壹』 sql語句如何實現將資料庫表中某個欄位的漢字批量轉為拼音

sql可以實現但是你要准備建立一個龐大的字典庫所有漢字拼音全存入然後寫函數一個個比對返回
我都是用程序寫的 sql實現比較蛋痛

『貳』 SQL語句提取出中文的拼音首字母

正好最近收藏了一個你可以看下思路
--將中文字元串轉化成文字首拼音的組合
create function 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)
--如果非漢字字元，返回原字元
set @PY=@PY+(case when unicode(@word) between 19968 and 19968+20901
then (select top 1 PY from (
select 'A' as PY,N'驁' as word
union all select 'B',N'簿'
union all select 'C',N'錯'
union all select 'D',N'鵽'
union all select 'E',N'樲'
union all select 'F',N'鰒'
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'

) 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
--函數調用實例：
select dbo.fun_getPY('中華人民共和國AAA01')

『叄』 sql 漢字轉拼音，若有重復的在拼音加1

題主意思，表a已經有欄位hz，現在要更新py這列？這樣的話，只要update就行了，為什麼說最好是函數實現呢？還是說題主想要selecthz,func(hz)froma這樣的呢？

函數。

首先需要一個解析漢字到拼音的方法，這里有一個包，你可以復制過去直接執行。

腳本地址：

http://www.cnblogs.com/mellowsmile/p/4601288.html

附代碼：

--不是我不貼，代碼太多貼不上，題主還是去上面那個地址復制吧，注意復制全部。

在SQL窗口執行。

我這里建了一個測試表test，數據顯示如下：

select a.* from test a;

題主，如此，可否？

『肆』如何在sql 中將表中一整列的漢字全部變成拼音首字母

CREATE FUNCTION Fun_GetPY
(
@Str NVARCHAR(4000)
)

RETURNS NVARCHAR(4000)

AS

BEGIN
DECLARE @Word NCHAR(1)
DECLARE @PY NVARCHAR(4000)

SET @PY = ''

WHILE LEN(@Str) > 0
BEGIN
SET @Word = LEFT(@Str, 1)

--如果非漢字字元，返回原字元
SET @PY = @PY + (CASE WHEN UNICODE(@Word) BETWEEN 19968 AND 19968 + 20901
THEN (SELECT TOP 1 PY FROM(
SELECT 'A' AS PY, N'驁' AS WORD
UNION ALL SELECT 'B',N'簿'
UNION ALL SELECT 'C',N'錯'
UNION ALL SELECT 'D',N'鵽'
UNION ALL SELECT 'E',N'樲'
UNION ALL SELECT 'F',N'鰒'
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'漚'
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'籜'
UNION ALL SELECT 'W',N'鶩'
UNION ALL SELECT 'X',N'鑂'
UNION ALL SELECT 'Y',N'韻'
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

調用這個函數就可以

『陸』資料庫oracle（plsql）怎麼把漢字轉化成拼音首字母,如果非漢字字元（英文or數字），返回原字元不變

oracle漢字轉拼音(獲得全拼/拼音首字母/拼音截取等)效果如下: Oracle 字元集 GBK 沒有問題 , UTF -8 需要修改一下Sql代碼

『柒』怎麼在SQL SERVER中把漢字轉化為拼音碼

『捌』漢字轉拼音的sql函數為什麼用到這些字 :驁簿錯鵽樲鰒腂夻攈穒鱳旀桛漚曝囕鶸蜶籜鶩鑂韻咗，求原理

沒人回答，自己找到了答案，整個sql排序規則是按照拼音排序，以此句sql為例：'A' AS PY,N'驁' AS word 」驁「字代表的是以A開頭的拼音，並且音調是也要排最後的一個字，讀做「ào」，所以得出在這個區間的漢字首字母都為A，以此類推可查出其他字母開頭的漢字首字母
