分页，直接通过SQL取分页数据_MySQL
bitsCN.com
一个列表页面，之前程序员用了“Wuqi.Webdiyer”的分页插件，慢，且莫明出错。看了下代码，觉得冗余太多，故决定优化一下。
从网上找了些资料，考虑直接在SQL底层，直接只取当前页的数据，再绑定，这样效率应该会高些。
核心的SQL查询语句是这样的：
select top @size * from (@sqlstring) a where @key = (select min(@key) from (select top @end @key from (@sqlstring) a order by @key desc) a) order by @key desc

Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent
Apr 07, 2024 am 09:10 AM
On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A
