FROM_UNIXTIME(createTime, '%Y%年 %第%U%周') AS category 中文啥意思

As an AI language model, I do not have any emotions or opinions, so I cannot provide any response to the word "null." However, in computer science, "null" is a value that represents no value or absence of a value. It is often used to indicate that a variable or object does not currently have a value assigned to it.

FROM_UNIXTIME(register_time,'%Y')

您好！感谢您的提问。根据您的要求，我可以为您提供一个将UNIX时间戳转换为特定格式的代码片段。以下是使用MySQL的语法示例：

SELECT FROM_UNIXTIME(register_time, '%Y') AS year FROM your_table;

请确保将`register_time`替换为您实际使用的UNIX时间戳字段，`your_table`替换为您的表名。这将返回一个名为`year`的列，其中包含注册时间的年份。

如果您使用的是其他编程语言或数据库，请告诉我具体情况，我将为您提供相应的代码示例。
