Import: mysql -u root -p -h localhost secondb < secondbschema.sql. So, to verify the SQL copy has been done correctly, you can inspect the generated file in order to make sure it is a SQL copy. Duplicating the database was easy: Export: mysqldump -no-data -tables -u root -p secondb > secondbschema.sql. That command will not generate any visual output. dump_filename.sql is the file that will be generated with all the database information.database_name must be replaced by the name of the database you want to export.username refers to the database user name.To start exporting the database, execute the following command into the command line: mysqldump -u username -p database_name > dump_filename.sql Once the backup is created, the file generated can be easily moved.
