1、create table hanzi2pinyin (id int,hanzi varchar(20),pinyin varchar(20) )
insert into 所有汉字和PINYIN
2、根据自己的需求创建一个函数,根据hanzi列返回pinyin列。
转:
1/ 此函数是将一个中文字符串的第一个汉字转成拼音字母 (例如:"中国人"->Z)
CREATE FUNCTION `fristPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8BEGIN
DECLARE V_RETURN VARCHAR(255)
SET V_RETURN = ELT(INTERVAL(CONV(HEX(left(CONVERT(P_NAME USING gbk),1)),16,10),
0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,0xBBF7,
0xBFA6,0xC0AC,0xC2E8,0xC4C3,0xC5B6,0xC5BE,0xC6DA,0xC8BB,
0xC8F6,0xCBFA,0xCDDA,0xCEF4,0xD1B9,0xD4D1),
'A','B','C','D','E','F','G','H','J','K','L','M','N','O','P','Q','R','S','T','W','X','Y','Z')
RETURN V_RETURN
END
2/此函数是将一个中文字符串对应拼音母的每个相连 (例如:"中国人"->ZGR)
CREATE FUNCTION `pinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8BEGIN
DECLARE V_COMPARE VARCHAR(255)
DECLARE V_RETURN VARCHAR(255)
DECLARE I INT
SET I = 1
SET V_RETURN = ''
while I < LENGTH(P_NAME) do
SET V_COMPARE = SUBSTR(P_NAME, I, 1)
IF (V_COMPARE != '') THEN
#SET V_RETURN = CONCAT(V_RETURN, ',', V_COMPARE)
SET V_RETURN = CONCAT(V_RETURN, fristPinyin(V_COMPARE))
#SET V_RETURN = fristPinyin(V_COMPARE)
END IF
SET I = I + 1
end while
IF (ISNULL(V_RETURN) or V_RETURN = '') THEN
SET V_RETURN = P_NAME
END IF
RETURN V_RETURN
END
3/ select pinyin(partname)
from 表
CREATE FUNCTION `fristPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8BEGIN
DECLARE V_RETURN VARCHAR(255)
SET V_RETURN = ELT(INTERVAL(CONV(HEX(left(CONVERT(P_NAME USING gbk),1)),16,10),
0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,0xBBF7,
0xBFA6,0xC0AC,0xC2E8,0xC4C3,0xC5B6,0xC5BE,0xC6DA,0xC8BB,
0xC8F6,0xCBFA,0xCDDA,0xCEF4,0xD1B9,0xD4D1),
'A','B','C','D','E','F','G','H','J','K','L','M','N','O','P','Q','R','S','T','W','X','Y','Z')
RETURN V_RETURN
END
pinyin :此函数是将一个中文字符串对应拼音母的每个相连 (例如:"中国人"->ZGR)
复制代码 代码如下:
CREATE FUNCTION `pinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
DECLARE V_COMPARE VARCHAR(255)
DECLARE V_RETURN VARCHAR(255)
DECLARE I INT
SET I = 1
SET V_RETURN = ''
while I <LENGTH(P_NAME) do
SET V_COMPARE = SUBSTR(P_NAME, I, 1)
IF (V_COMPARE != '') THEN
#SET V_RETURN = CONCAT(V_RETURN, ',', V_COMPARE)
SET V_RETURN = CONCAT(V_RETURN, fristPinyin(V_COMPARE))
#SET V_RETURN = fristPinyin(V_COMPARE)
END IF
SET I = I + 1
end while
IF (ISNULL(V_RETURN) or V_RETURN = '') THEN
SET V_RETURN = P_NAME
END IF
RETURN V_RETURN
END

复制代码 代码如下:
mysql>select p.province, fristPinyin(p.province), pinyin(p.province) from province p
+------------------+-------------------------+--------------------+
