Since we will look at ORACLE recursive queries, we should be clear about what recursion means. Here I will not explain it more, but I will just give a brief introduction.
The so-called recursive query makes the data structure in the data table conform to the basic conditions of recursive query, that is, the table has the ID and PID (node number, parent node number) if the data is displayed in the UI, it should be one or more trees.
We need to explain the process of recursively querying the child
