帮我看看下面的错误信息并帮我提出解决方式，这是Navicat中的错误，CREATE TABLE `selection` ( `id` int(0) NOT NULL AUTO_INCREMENT, `student_id` int(0) NOT NULL, `course_id` int(0) NULL DEFAULT NULL, `selection_time` datetime(0) NOT NULL, `status` int(0) NOT NULL DEFAULT 0, PRIMARY KEY (`id`) USING BTREE, INDEX `student_id`(`student_id`) USING BTREE, INDEX `course_id`(`course_id`) USING BTREE, CONSTRAINT `selection_ibfk_1` FOREIGN KEY (`student_id`) REFERENCES `student` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT, CONSTRAINT `selection_ibfk_2` FOREIGN KEY (`course_id`) REFERENCES `course` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT ) ENGINE = InnoDB AUTO_INCREMENT = 21 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic > 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(0) NOT NULL, `status` int(0) NOT NULL DEFAULT 0, PRIMARY KEY (`id`) USING' at line 5 > 时间: 0s

这个错误是因为在创建数据表时，`datetime` 数据类型的括号中不能指定长度。

要解决这个问题，您可以使用以下 SQL 语句：

CREATE TABLE `selection` (
  `id` int(0) NOT NULL AUTO_INCREMENT,
  `student_id` int(0) NOT NULL,
  `course_id` int(0) NULL DEFAULT NULL,
  `selection_time` datetime NOT NULL,
  `status` int(0) NOT NULL DEFAULT 0,
  PRIMARY KEY (`id`) USING BTREE,
  INDEX `student_id`(`student_id`) USING BTREE,
  INDEX `course_id`(`course_id`) USING BTREE,
  CONSTRAINT `selection_ibfk_1` FOREIGN KEY (`student_id`) REFERENCES `student` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT,
  CONSTRAINT `selection_ibfk_2` FOREIGN KEY (`course_id`) REFERENCES `course` (`id`) ON DELETE RESTRICT ON UPDATE RESTRICT
) ENGINE = InnoDB AUTO_INCREMENT = 21 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;

请注意，我只是删除了 `datetime` 数据类型括号中的 `(0)` 部分。
