Ok so I am in a situation where I need to dump the results of a sql query into a file and this is for backup purpose I tried running th following from my terminal : 

```
mysql -e "select * from products where brand_id=5" -u root -p database_name > dumpfile.sql

```

this dumps the data but with the "insert into statements", so if later on I want to dump this data back into my database I will be re-composing it. And that is not the correct approach. So please suggest me how do I dump query results for back up purpose ?
