Sometimes when writing a program, the background requires a large amount of data to be imported into the database. For example, computer test score inquiries, phone book data, etc. are generally stored in excel. At this time, we can export the data into a csv file and then use The following program can batch import data into the database in the background.
The following is just the main program part:
The code is as follows
