mysql实现用拼音搜索中文的数据库实现

1、创建表：

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、插入数据：

INSERT INTO t_base_pinyin (pin_yin_, code_)
VALUES
    ("a", 20319),
    ("ai", 20317),
    ("an", 20304),

3、创建函数：

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、创建视图：

CREATE VIEW v_pinyin AS SELECT
    u.id,
    to_pinyin (u.displayname) AS pinyin,
    u.displayName
FROM
    wsm_userinfo u
