Relying on pre-written scripts for important things like admin systems is a step in the wrong direction, especially if you want to understand or change it in the future. If you are interested in learning about SQL yourself, perhaps start with the native sa-mp system.

This shares a lot of syntax / functionality with the more advanced SQL plugins, and will be a good learning experience for you.
