Hi Namratashukla, I don't see a problem in updating a large number of records in database tables. You ask how - the answer is using UPDATE or INSERT statement.

I'm not sure if you're new to SQL (then google for "sql tutorial" or "sql reference") or if you didn't provide enough information. Why do you think that updating the db will be a problem? If you have many db tables then maybe your database design is bad and you should use less db tables (e.g. not one db table for each player).
