- 之前在网上搜索按时间统计，发现不是很全 ，接着别人的思路进行延伸下，
- mysql统计天、周、月、季度、半年、年
- 前期工作创建辅助表
CREATE TABLE num (i INT);
INSERT INTO num (i) VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9); - 创建要查询的表
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(32) NOT NULL COMMENT '用户名称',
`sex` char(1) DEFAULT NULL COMMENT '性别',
`address` varchar(256) DEFAULT NULL COMMENT '地址',
`create_time` varchar(100) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8; -- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('', '小南', '男', '湖南湘潭', '2019-07-01');
INSERT INTO `user` VALUES ('', '小谭', '男', '湖南湘潭', '2019-07-02');
INSERT INTO `user` VALUES ('', '小梅', '女', '广东梅县', '2019-07-01');
INSERT INTO `user` VALUES ('', '小仪', '女', '四川仪陇', '2019-05-10');
INSERT INTO `user` VALUES ('', '小蓝', '女', '上海嘉定', '2019-11-11');
INSERT INTO `user` VALUES ('', '小苍', '男', '湖南湘潭', '2018-06-01');
INSERT INTO `user` VALUES ('', '小萨', '男', '湖南湘潭', '2018-01-02');
INSERT INTO `user` VALUES ('', '小静', '女', '广东梅县', '2018-06-01');
INSERT INTO `user` VALUES ('', '大幂幂', '女', '四川仪陇', '2019-03-10');
INSERT INTO `user` VALUES ('', '宋小宝', '女', '上海嘉定', '2019-05-11');
按天统计

按年统计（近五年）
SELECT
