MySQL allows you to import text files to databases and export tables to text files.

1. Export a table to a text file Command: Select * From tablename into OUTFILE 'a.txt' // Note: a.txt can be replaced with your own path, for example, D:/mydatabase/a.txt. If no path is added, it is saved to the directory where the database table is located by default.

2. import data from text files to database tables

Command: load data local infile 'd:/test.txt 'into Table Name (Field 1, Field 2 ,...)

Of course, you need to create a table first, and the Data Type of each field is the same as that of each column of the text file.
