MySQL 多个%等模糊查询功能实现

目录一、建表并插入数据1、创建一个people表2、向people表添加数据二、查询语句一、建表并插入数据1、创建一个people表DROP TABLE IF EXISTS `people`;CREATE TABLE `people` ( `id` int NOT NULL COMMENT '主键', `name` varchar(45) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL COMMENT '姓名', `sex` tinyint NOT NULL COMMENT '性别', `age` int NOT NULL COMMENT '年龄', `phone` varchar(45) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL COMMENT '联系方式', PRIMARY KEY (`id`) USING BTREE) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;2、向people表添加数据insert into people values(1,'测试人员',18,1,'13812345678');insert into people values(2,'测测人员',19,0,'13812345679');insert into people values(3,'人员测试',20,1,'13812345680');insert into people values(4,'测试人员1',21,0,'13812345681');insert into people values(5,'员人试测',22,1,'13812345682');二、查询语句-- 1、模糊查询（单个条件）select * from people where name like '%测%';

-- 2、模糊查询（多个条件）select * from people where name like '%测%' and name like '%人%';

select * from people where name like '%测%' or name like '%人%';

------有趣的查询（网页端前端传参%测试）------

-- 3、模糊查询（顺序执行）select * from people where name like '%测%人%';

select * from people where name like '%人%测%';

-- 4、_： 表示任意单个字符。匹配单个任意字符，它常用来限制表达式的字符长度语句select * from people where name like '测试人员_';

select * from people where name like '__人员';

注：mysql 通配符查询必须用 rlike

-- 5、[ ]：表示括号内所列字符中的一个（类似正则表达式）。指定一个字符、字符串或范围，要求所匹配对象为它们中的任一个。select * from people where name rlike '[试]人员';

-- 6、[^ ] ：表示不在括号所列之内的单个字符。其取值和 [] 相同，但它要求所匹配对象为指定字符以外的任一个字符 ^ 非。select * from people where name rlike '[^试]人员';

-- 7、^：以xx开头的记录select * from people where name rlike '^测';

-- 8、$：以xx结尾的记录select * from people where name rlike '员$';

-- 9、.：任意单个的select * from people where name rlike '.人员';
