Code:
create table if not exists inventory (SteamID int);
insert into inventory(SteamID) values(-2127214489);
Yes it's a string in the query but it is then stored as an integer inside the database which requires less space.
I did try to confirm my code in the beginning by using the nVault editor but it wouldn't start on my system. More info on that in the nVault editor thread.
