Most programmers who have done client programs know that when End Users fill in data on the interface, if there is a drop-down tree (for example) for data with a large number of layers ), it adds a lot of colors to the application and increases the efficiency of end user operations.

MySQL and Python implement ranking window functions most databases provide window functions, such as RANK and ROW_NUMBER. MySQL is not directly provided in this respect, but it can be implemented in disguise. I have previously written the implementation of row_number. Today I have time to post the implementation of rank. Here, I use MySQL and Python to implement rank

The classes in Delphi and C # both provide the concept of "attribute", so that the Getter and Setter methods can be as simple as accessing members. The following Delphi code:TMyClass = classPrivateFValue: Integer;Funcation GetValue: Integer;Procedure SetValue (value: Integer );PublicProperty Value: Integer read GetValue write SetValue;End;The red part is the attribute declaration. You can directly read and write the Value in the future, as shown below:MyClass. Value := 100;V = MyClass. Value;Att
