mysql：为查询创建常规表而不是临时表是一种好习惯吗？

Question

I need to put all the result of a query to a temporary table then select from it, but due to the nature of the temporary table, I cannot refer to it more than once in the same query. So is it ok to create a uniquely named (regular) table for this and drop it after the query is completed? Or is there a better way to do this?

I tried using Derived tables but I cannot access it from different blocks.

Answer 1

It's not necessarily a matter of whether it's good practice or not. Whether it's a regular table, temporary table or derived table they all serve a purpose when trying to accomplish a task. Therefore, creating a regular table or a temporary table all depends on you and what you want your application to accomplish at the end of the day.

But based on your problem it seems that you might need to create a regular table in this situation since you require access to the table more than once, and you can drop the table after you're finished with it.
