Ⅰ 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
--oracle漢字轉拼音 PACKAGE
--1.獲得全拼
SELECT GETHZPY.GETHZFULLPY('漢字') FROM DUAL;結果 : HanZi
--2.拼音首字母
SELECT GETHZPY.GETHZPYCAP('漢字') FROM DUAL;結果 : HZ
--3.拼音截取等
SELECT GETHZPY.GETHZPYCAPSUBSTR('漢字', 0, 1) FROM DUAL;結果 : H
代碼部分太長掛在附件上 以下代碼如果在 PL/SQL Developer 執行的話,選擇 Command Window 粘貼.

Ⅲ 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？
Ⅳ 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
Ⅳ SQL 到底應該怎麼念
sql讀作/ˈes kjuː ˈel/ "S-Q-L").
SQL(Structured Query Language)簡稱SQL(結構化查詢語言，是一種特殊目的的編程語言，是一種資料庫查詢和程序設計語言，用於存取數據以及查詢、更新和管理關系資料庫系統；同時也是資料庫腳本文件的擴展名。
結構化查詢語言是高級的非過程化編程語言，允許用戶在高層數據結構上工作。它不要求用戶指定對數據的存放方法，也不需要用戶了解具體的數據存放方式，所以具有完全不同底層結構的不同資料庫系統, 可以使用相同的結構化查詢語言作為數據輸入與管理的介面。結構化查詢語言語句可以嵌套，這使它具有極大的靈活性和強大的功能。
1986年10月，美國國家標准協會對SQL進行規范後，以此作為關系式資料庫管理系統的標准語言（ANSI X3. 135-1986），1987年得到國際標准組織的支持下成為國際標准。不過各種通行的資料庫系統在其實踐過程中都對SQL規范作了某些編改和擴充。所以，實際上不同資料庫系統之間的SQL不能完全相互通用。
Ⅵ SQL 獲取名字拼音
做兩個函數。一個取漢字拼音首字母，一個取完整拼音
下面代碼是晚上搜到的：
--取漢字首字母函數
create function f_GetPy(@str nvarchar(4000))
returns nvarchar(4000)
as
begin
declare @strlen int,@re nvarchar(4000)
declare @t table(chr nchar(1) collate Chinese_PRC_CI_AS,letter nchar(1))
insert into @t(chr,letter)
select '吖','A' union all select '八','B' union all
select '嚓','C' union all select '咑','D' union all
select '妸','E' union all select '發','F' union all
select '旮','G' union all select '鉿','H' union all
select '丌','J' union all select '咔','K' union all
select '垃','L' union all select '嘸','M' union all
select '拏','N' union all select '噢','O' union all
select '妑','P' union all select '七','Q' union all
select '呥','R' union all select '仨','S' union all
select '他','T' union all select '屲','W' union all
select '夕','X' union all select '丫','Y' union all
select '帀','Z'
select @strlen=len(@str),@re=''
while @strlen>0
begin
select top 1 @re=letter+@re,@strlen=@strlen-1
from @t a where chr<=substring(@str,@strlen,1)
order by chr desc
if @@rowcount=0
select @re=substring(@str,@strlen,1)+@re,@strlen=@strlen-1
end
return(@re)
end
go
--使用
select id,name,dbo.f_GetPy(name) from mytable
取完整拼音的跟上述f_GetPy函數類似，只是臨時表要多寫很多行，拼音有多少種組合就寫多少行，大概六七百行吧。你自己找找相關的其他語言轉拼音全碼的代碼，實現方式是相通的。
Ⅶ 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
Ⅷ sql中怎麼根據漢字的拼音首字母查詢
--SQLServer:
---測試數據---
ifobject_id('[pactinfo]')isnotnulldroptable[pactinfo]
go
createtable[pactinfo]([ID]int,[pactname]varchar(4))
insert[pactinfo]
select1,'正常'unionall
select2,'中國'unionall
select3,'做飯'unionall
select4,'加發'
---引用前輩們的一個函數---
createfunctionf_GetPy(@strnvarchar(4000))
returnsnvarchar(4000)
as
begin
declare@strlenint,@renvarchar(4000)
declare@ttable(chrnchar(1)collateChinese_PRC_CI_AS,letternchar(1))

from@tawherechr<=substring(@str,@strlen,1)
orderbychrdesc
if@@rowcount=0
select@re=substring(@str,@strlen,1)+@re,@strlen=@strlen-1
end
return(@re)
end
---查詢---
select

---結果---
