mysql统计天、周、月、季度、半年、年

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 ('1', '小南', '男', '湖南湘潭', '2019-07-01');
INSERT INTO `user` VALUES ('2', '小谭', '男', '湖南湘潭', '2019-07-02');
INSERT INTO `user` VALUES ('3', '小梅', '女', '广东梅县', '2019-07-01');
INSERT INTO `user` VALUES ('4', '小仪', '女', '四川仪陇', '2019-05-10');
INSERT INTO `user` VALUES ('5', '小蓝', '女', '上海嘉定', '2019-11-11');
INSERT INTO `user` VALUES ('6', '小苍', '男', '湖南湘潭', '2018-06-01');
INSERT INTO `user` VALUES ('7', '小萨', '男', '湖南湘潭', '2018-01-02');
INSERT INTO `user` VALUES ('8', '小静', '女', '广东梅县', '2018-06-01');
INSERT INTO `user` VALUES ('9', '大幂幂', '女', '四川仪陇', '2019-03-10');
INSERT INTO `user` VALUES ('10', '宋小宝', '女', '上海嘉定', '2019-05-11');

按天统计

SELECT

按周统计
