How to export the structures of all tables in a MySQL database?

To export the structure of all tables in a MySQL database, you can use the following command:

mysqldump -u username -p --no-data database_name > output_file.sql

In the command, “username” is the database username, “database_name” is the name of the database to be exported, and “output_file.sql” is the name of the exported file. This command will export the structure information of all tables in the database to the specified file.
