MySQL obtains the first N records of all categories, and mysql obtains all categories.
For example, if you have an Article table Article (Id, Category, InsertDate), you need to use SQL to find a set of the First N data records of the latest time in each type. It has a good piece of code and is reserved.
SELECT A1.* FROM Article AS A1 INNER JOIN (SELECT A.Category,A.InsertDate FROM Article AS A

When writing object-oriented programs, it is often necessary to add some new behavior to an existing class, usually with the method of creating subclasses. However, sometimes the subclass is inconvenient, for example, to add a new behavior for the NSString class, but NSString is actually a surface form of a class cluster, so creating subclasses for such a class can be very difficult. Using the dynamic run-time mechanism of objective-c, you can use categories

This article is a Demo for the specific needs I encountered during the project process. There is no great versatility, and readers can bypass it as appropriate.
The title cannot fully express the intention. The exact scenario needs to be expanded. Assume that there are three levels of classification. The design of classification is as follows:

Classification algorithms are used in multiple independently developed systems. Each data may be divided into several categories. Detailed scores can be simply placed in a redundant table, however, the category of each data entry must be recorded in the original data table. There are several difficult problems. One is to search for categories, and the other is to add ca
