During the process of inserting data into the database,If you need to insert numbers into multiple tables,And there are dependencies between multiple tables,Inserting data analysis at this time is too cumbersome
For example I have three tables:

• I want to insert data into these tables,But some relationships are strong associations
• Table structure attached: Idea database
  备注: This method is not optimal,The association between multi-table inserts can be temporarily satisfied,Further improvements will be made if necessary
