So you have a database with loads of tables. You want the table definitions of all of them. You don’t really need the data. mysqldump to the rescue!
mysqldump -u USERNAME --password=PASSWORD --no-data --opt DB1 > DUMPFILE
That’s it! Easy as a pie 
The key here is the –no-data option. It dumps all the table definitions, but not the table data.
Want to do this for multiple databases? No problem.
mysqldump -u USERNAME --password=PASSWORD --no-data --opt --databases DB1 DB2 > DUMPFILE
The –databases option allows you to add multiple databases.
mysqldump -u USERNAME --password=PASSWORD --no-data --opt --all-databases > DUMPFILE
The –all-databases option allows you to dump all the databases.
mysqldump -u USERNAME --password=PASSWORD --no-data --opt DB1 --ignore-table DB1.TABLENAME1 --ignore-table DB1.TABLENAME2 > DUMPFILE
–ignore-table option allows you to skip dumping certain tables. Do not forget to specify the databasename when using this option.
