The query () function of the model is sometimes very useful, and it can execute SQL statements wherever the data is needed.But not where the query () method is invoked is appropriate. In particular, invoking the model's query () method directly in the controller$this->mymodel->query (' Here comes the SQL statement ');Calling the model's query method in the controller is not possible, but it introduces database-related code, which violates the principles of the MVC patternA cleaner solution is to

Recommendation 73: Avoid locking inappropriate synchronization objectsIn C #, another way to encode thread synchronization is to use the thread lock. The principle of the thread lock is that it locks a resource so that the application has only one thread to access it at the moment. In layman's words, it makes multithreading a single thread. In C #, a locked resource can be understood as a new normal CLR object.Since the resource that needs to be locke
