To follow up on the answer you have already, try Googling for 'bulk load database'.

Database designers understand that it may be necessary to load a database using thousands, millions or billions of records during setup. The INSERT command is expected to be used for singleton INSERTs, but there are certainly other options for a database load. I used bcp (bulk copy) with Ingres, going on about 12 years ago, and MySQL has a function called LOAD DATA INFILE.

Just do a little research and you'll find a solution that works for you.
