If you do a data-only dump (no table or database DROP lines), then yes, it should append. (Always back up your database/tables before you attempt to do this!  Just to make sure.)

However, if you have a PRIMARY KEY or an AUTO_INCREMENT field, you'll run into problems, as you'll get collisions.

Is this the only method that is to empty the data and run the dump to get the lates data.
Are there other ways if you want to load the data periodically.
