MySQL實現用拼音搜索中文的數據庫實現
1、創建表：
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; 2、插入數據：
INSERT INTO t_base_pinyin (pin_yin_, code_)
VALUES
("a", 20319),
("ai", 20317),
("an", 20304),

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 ;
4、創建視圖：
CREATE VIEW v_pinyin AS SELECT
u.id,
to_pinyin (u.displayname) AS pinyin,
u.displayName
FROM
wsm_userinfo u
