After the database import operation, is the original database overwritten? Or is it merged with the original data?

You can open your sql and take a look and you will understand.

The first sentence of each execution is DROP TABLE IF EXISTS `app`; and then create the table, so the original table is deleted first and then created. Create a new table, and then use insert to import data
