Вот сам код:

public OnPlayerRequestClass(playerid, classid)
{
    SetPlayerPos(playerid, 1958.3783, 1343.1572, 15.3746);
    SetPlayerCameraPos(playerid, 1958.3783, 1343.1572, 15.3746);
    SetPlayerCameraLookAt(playerid, 1958.3783, 1343.1572, 15.3746);
    GetPlayerName(playerid, pInfo[playerid][pName], MAX_PLAYER_NAME);
    new query_string[52+MAX_PLAYER_NAME];
    format(query_string, sizeof(query_string), "SELECT * FROM `accounts` WHERE `player_name` = '%s'", pInfo[playerid][pName]);
    mysql_function_query(mysql_connect_ID, query_string, true, "FindPlayerInTable","i", playerid);
    return 1;
}
