          	SetPVarFloat(playerid, "posx", data[1]);
          	SetPVarFloat(playerid, "posy", data[2]);
          	SetPVarFloat(playerid, "posz", data[3]);
          	SetPVarFloat(playerid, "poszy", data[4]);

Shouldn't they be SetPVarFloat?
and look at mysql log file

and make sure that

data[1]
data[2]
data[3]
data[4]

are floats
