MySQL problems

[SarahKerrigan]

Every time I connect to my server it creates a new row for my MySQL database.
Im using MySQLoo and changed PointShop's MySQL addon to work as with my gamemode(credits there)
Im obvious a noob with MySQL thats why I copied PointShops system.
Please don't write how to solve it as you need to check for dat in MySQL etc etc as I have zero knowledge of how a MySQL database really works.
tl;dr I prefer if you solve it for me but do it in steps so I can understand. Not just HERES THE CODE:

 as I need to learn :).

Thats what I mean by creating a new row every time I join (as the same player)

Code calling the safe and loading function:
[lua]function savePlayerData(ply, hp,xp,lvl,walk,run,stamina,money,points,armor)
	MySQLSetData(ply,hp,xp,lvl,walk,run,stamina,money,points,armor)
end
hook.Add("PlayerDisconnected", "savePlayerData", savePlayerData)

function getPlayerData(ply, callback)

	MySQLGetData(ply, function(hp,xp,lvl,walk,run,stamina,money,points,armor)
		callback(
		ply:SetNWInt("Health",tonumber(hp)),
		ply:SetNWInt("xp", tonumber(xp)),
		ply:SetNWInt("lvl", tonumber(lvl)),
		ply:SetNWInt("Walk speed", tonumber(walk)),
		ply:SetNWInt("Run speed", tonumber(run)),
		ply:SetNWInt("Stamina", tonumber(stamina)),
		ply:SetNWInt("expPoints", tonumber(points)),
		ply:SetNWInt("Armor", tonumber(armor))
		)
	end)

end
hook.Add("PlayerInitialSpawn", "givePlayerData", getPlayerData)[/lua]

Code for saving:
[lua]function MySQLSetData(ply, hp, xp, lvl, walk, run, stamina, money, points, armor)
	if not shouldmysql then return; end
    local qs = [[
    INSERT INTO `deathmatch_player` (uniqueid, hp,xp,lvl,walk,run,stamina,money,points, armor)
    VALUES ('%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s')
    ON DUPLICATE KEY UPDATE 
        hp = VALUES(hp),
		xp = VALUES(xp),
		lvl = VALUES(lvl),
		walk = VALUES(walk),
		run = VALUES(run),
		stamina = VALUES(stamina),
		money = VALUES(money),
		points = VALUES(points),
		armor = VALUES(armor)
    ]]
    qs = string.format(qs, ply:UniqueID(), hp or 0, xp or 0, lvl or 0, walk or 0, run or 0, stamina or 0, money or 0, points or 0, armor or 0)
    local q = db:query(qs)
     
    function q:onError(err, sql)
        if db:status() ~= mysqloo.DATABASE_CONNECTED then
            db:connect()
            db:wait()
        if db:status() ~= mysqloo.DATABASE_CONNECTED then
            ErrorNoHalt("Re-connection to database server failed.")
            return
            end
        end
        MsgN('[Operation Strike] MySQL Query Failed: ' .. err .. ' (' .. sql .. ')')
        q:start()
    end
     
    q:start()
end[/lua]
