这个错误提示是因为在插入语句中,datetime 数据类型的列没有指定数据类型,导致 SQL 语法错误。
正确的语法应该是:
```
INSERT INTO exam_record (uid, exam_id, start_time, submit_time, score) VALUES ('1001', '9001', '2021-09-01 22:11:12', '2021-09-01 23:01:12', 90), ('1002', '9002', '2021-09-01 22:11:12', null, null);
```
在这个语句中,datetime 类型的数据需要使用 ISO 8601 格式的日期时间字符串表示,即 'YYYY-MM-DD HH:MM:SS',例如 '2021-09-01 22:11:12'。同时,null 值也需要直接写为 null,而不是用字符串表示。

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 'book_desc bigint created Datetime Updated Datetime
It seems like you have encountered an error in your SQL syntax. The error message suggests that there is a problem near the line that starts with 'book_desc bigint created Datetime Updated Datetime'.
To fix this error, you need to provide the correct syntax for creating a table in MySQL. Here's an example of how you could create a table with the columns mentioned:
```
CREATE TABLE books (
book_id INT PRIMARY KEY AUTO_INCREMENT,
book_desc TEXT,
created DATETIME,
updated DATETIME
);
```
Please note that this is just an example, and you may need to modify it based on your specific requirements. Additionally, make sure to consult the MySQL documentation for the correct syntax that corresponds to your MySQL server version.
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 ' `create_time` datetime NOT NULL DEFAULT '2008-04-27 09:27:43',
这个错误提示意味着你在执行 SQL 语句时使用了错误的语法。具体来说,错误可能是在 `create_time` 字段定义的语法上。
在 MySQL 中,`datetime` 类型的字段需要指定长度。例如,应该这样定义:`datetime(6)`。此外,您还需要使用逗号分隔字段定义。因此,正确的语法应该是这样的:
```
`create_time` datetime(6) NOT NULL DEFAULT '2008-04-27 09:27:43',
```
请注意,这里我假设您想将 `create_time` 字段定义为 `datetime` 类型,长度为 6,不能为空,并且默认值为 '2008-04-27 09:27:43'。
如果您需要进一步帮助,请提供完整的 SQL 语句和您使用的 MySQL 版本。
