This should come with your server pack, same as config.lua and the data folder.
It depens on which server you are using how it's called, it can also be forgotten.sql or schema.sql.
In TFS 0.3/0.4 servers it's in the folder schemas and called mysql.sql.
You can use one from an other server if this server is similar, however, there will probable still a few problems/errors if there are differences.
