一、創建拼音對照表
復制代碼 代碼如下:
-- 創建漢字拼音對照臨時表
CREATE TABLE IF NOT EXISTS `t_base_pinyin` (
`pin_yin_` varchar(255) CHARACTER SET gbk NOT NULL,
`code_` int(11) NOT NULL,
PRIMARY KEY (`code_`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
二、插入對照數據
復制代碼 代碼如下:
-- 插入數據
INSERT INTO t_base_pinyin (pin_yin_,code_) VALUES ("a", 20319),("ai", 20317),("an", 20304),("ang", 20295),("ao", 20292),("ba", 20283),("bai", 20265),("ban", 20257),("bang", 20242),("bao",

三、創建漢字轉換拼音函數
復制代碼 代碼如下:
-- 建立漢字轉換拼音函數
DROP FUNCTION IF EXISTS to_pinyin;
DELIMITER $
CREATE FUNCTION to_pinyin(NAME VARCHAR(255) CHARSET gbk)
RETURNS VARCHAR(255) CHARSET gbk
BEGIN
DECLARE mycode INT;
DECLARE tmp_lcode VARCHAR(2) CHARSET gbk;
DECLARE lcode INT;
DECLARE tmp_rcode VARCHAR(2) CHARSET gbk;
DECLARE rcode INT;
DECLARE mypy VARCHAR(255) CHARSET gbk DEFAULT '';
DECLARE lp INT;
SET mycode = 0;
SET lp = 1;
SET NAME = HEX(NAME);
WHILE lp < LENGTH(NAME) DO
SET tmp_lcode = SUBSTRING(NAME, lp, 2);
SET lcode = CAST(ASCII(UNHEX(tmp_lcode)) AS UNSIGNED);
SET tmp_rcode = SUBSTRING(NAME, lp + 2, 2);
SET rcode = CAST(ASCII(UNHEX(tmp_rcode)) AS UNSIGNED);
IF lcode > 128 THEN
SET mycode =65536 - lcode * 256 - rcode ;
SELECT CONCAT(mypy,pin_yin_) INTO mypy FROM t_base_pinyin WHERE CODE_ >= ABS(mycode) ORDER BY CODE_ ASC LIMIT 1;
SET lp = lp + 4;
ELSE
SET mypy = CONCAT(mypy,CHAR(CAST(ASCII(UNHEX(SUBSTRING(NAME, lp, 2))) AS UNSIGNED)));
SET lp = lp + 2;
END IF;
END WHILE;
RETURN LOWER(mypy);
END;
$
DELIMITER ;
四、使用方法
復制代碼 代碼如下:select to_pinyin('測試')
輸出結果：
