Yes, that is how it works. It is essentially replacing the existing record. So you will need to know all existing info when using this.

Suppose current XP is 10 and you want to add 1 XP to the DB, when you use replace into, you would provide XP + 1.

REPLACE INTO tblStuff (SteamID, XP) VALUES ('%s', %d);" , szSteamID , CurrentXP + 1 );

If you are doing this only because you are losing data with nVault, you can simplify this by just fixing your nVault issue.
