当每个用户的日期时间输入和日期时间退出之间的差值小于三分钟时，我需要用值1更新

tSet

在这种情况下，我需要此输出，因为对于用户

如何解决这个问题？拜托，你能帮我吗

我的创建表代码如下：

DROP TABLE IF EXISTS `ttableuser`;
CREATE TABLE `ttableuser` (
  `tID` int(11) NOT NULL,
  `tDate` datetime DEFAULT NULL,
  `tUser` int(11) DEFAULT NULL,
  `tDescription` varchar(255) DEFAULT NULL,
  `tSet` int(1) DEFAULT NULL,
  PRIMARY KEY (`tID`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

-- ----------------------------
-- Records of ttableuser
-- ----------------------------
INSERT INTO `ttableuser` VALUES ('707951537', '2020-02-11 11:17:13', '13117', 'STARTED ACCESS USER', null);
INSERT INTO `ttableuser` VALUES ('707757026', '2020-02-11 11:16:05', '43409', 'STARTED ACCESS USER', null);
INSERT INTO `ttableuser` VALUES ('707765459', '2020-02-11 09:28:42', '16920', 'ENDING  ACCESS USER', null);
INSERT INTO `ttableuser` VALUES ('707765775', '2020-02-11 09:27:13', '16920', 'STARTED ACCESS USER', null);
INSERT INTO `ttableuser` VALUES ('707767122', '2020-02-11 09:15:46', '30303', 'STARTED ACCESS USER', null);
INSERT INTO `ttableuser` VALUES ('707789986', '2020-02-11 09:13:18', '49798', 'STARTED ACCESS USER', null);

INSERT INTO `ttableuser` VALUES ('707965127', '2020-02-11 06:08:16', '41190', 'STARTED ACCESS USER', null);

考虑以下几点

DROP TABLE IF EXISTS my_table;

CREATE TABLE my_table(
  `tID` int(11) NOT NULL,
  `tDate` datetime DEFAULT NULL,
  `tUser` int(11) DEFAULT NULL,
  `tDescription` varchar(255) DEFAULT NULL,
  `tSet` int(1) DEFAULT NULL,
  PRIMARY KEY (`tID`)
);

INSERT INTO my_table VALUES

假设每个用户只访问系统（最多）两次

…并根据需要添加一个按天过滤的条件

SELECT x.*

选择x.*
从我的表x
加入我的桌子
在y.tuser=x.tuser和y.tid>x.tid上
y.tdate


根据您想要修改的行，上面的更新可能是
