RPG ONLINE GAME DATABASE SQL (Navicat if posible) DEVELOPER.

I need a SQL specialist that can help me to develop new functions, edit tables (example, modify a column with a PK from tinyint to smallint without losing data, ) for my game (online server). I have limited knowledge, but I will try to assist you in the task as much as I am able to.

Example of functions I need to create:

If you need any understanding on how the game works, I will send you the game files so you can check.

Budget is 20e per hour.
