MySQL表具有固定的行数? [英] MySQL table with fixed number of rows?

问题描述

我有桌子documents (id, name, time).是否有特殊的sql命令将表限制设置为10行?

I have table documents (id, name, time). Is there a special sql command to set table limit by 10 rows?

推荐答案

如果只想显示最新生成的10个文档"，则不需要单独的表.只需在现有表上使用查询即可:

If you just want to display the "latest 10 generated documents", no need for a separate table. Just use a query on your existing table:

SELECT id, name, `time`
FROM documents
ORDER BY `time` DESC
LIMIT 10
