When I saw a program in the library management system yesterday, I found that the database files are MYI, frm, and myi files, which are not commonly used. SQL files, which have never been used before, have not been noticed before. I searched for it online. Oh, it was smoothly imported into MYSQL.

By default, only the database table structure files are generated when the database and table are created. frm. to use the database properly, you must have three format database table files.

Open your data directory in mysql, you may also encounter another file format. opt you can open it in a text editor, you can see that the saved encoding information .. Frm, myd, and myi are data files stored in MySQL, and phpMyAdmin cannot be imported. PhpMyAdmin supports SQL files. The following is an introduction to the operation methods.
