mybatis的mapper文件中的一个标签是否可以写多条SQL语句？是否存在事物？

Create Table

CREATE TABLE `test` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(10) DEFAULT NULL,
  `age` int(3) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=20 DEFAULT CHARSET=utf8mb4

url: jdbc:mysql://XXX.XXX.XXX.XXX:XXX/XXXX

Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
