When I was working on a project, I encountered a scenario where there were two tables with a data volume of around million. Now I want to merge these two tables into one table in the production environment, I originally wanted to use the SQL statement insert into select for implementation. Later I found that this operation was slow because of the computing logic. The approximate table structure is as follows: Table1 Id tel credits1 Table 2 Id tel credits2 points The merged table is Tab

and then send a cookie to the server---> return page information. Get the data to the score page and use regular expressions to take the scores and credits out separately and calculate the weighted average. OK, it looks like a very simple kind of paper. Let's try it down there. But before the experiment, there was one more problem, that is, where is the post data sent to? Then look at the original page: is obviously implemented with an HTML framewor

In these 16 credits, I have basically never been to 13 credits o
