Not really sure about how exactly MySQL works but would using..

pawn Код:

mysql_tquery(mysql, query, "OnAccountCheck", "i", playerid);

be the same as..

pawn Код:

OnAccountCheck(playerid);

?

I've no idea what mysql_tquery actually is so..

You could always replace it with OnAccountCheck(playerid); and see if it works.
