rAthena SQL structure definitive guide

[exdee]

Good day all,

Unfortunately my Internet searches led me to nothing. I was looking for rathena sql database structure description. I mean some source where all tables and their columns are explained, with examples, (all)possible values, their ingame meaning, use cases, etc.

I don't mean obvious ones like "login.account_id" or "char.name" but something is less intuitively understandable like "inventory.option_parm0"

looking in corresponding .yml files at the top usually tell you what each thing means. in this case items_equip.yml
