Вот код:

CMD:setleader(playerid, params[])
{
        static fracname[100], string[150];
        if(sscanf(params, "ud", params[0], params[1])) return SendClientMessage(playerid, COLOR_WHITE, "Комманда была использована не верно. Пишите: /setleader [id] [№ раздела]");
        if(Player[playerid][pSex] == 1)
        {
        if(params[1] == 1) fracname = "Los Santos Police Deportament", Player[params[0]][pModel] = 288;
   	    }
        else
        {
        if(params[1] == 1) fracname = "Los Santos Police Deportament", Player[params[0]][pModel] = 219;
        }
    }
    format(string, sizeof(string), "{FFFF00}Вы назначили %s руководить организацией \"%s\"", PlayerName(playerid), fracname);
    SendClientMessage(playerid, COLOR_ORANGE, string);
    format(string, sizeof(string), "{FFFF00}Администратор %s назначил вас руководить организацией \"%s\"", Player[playerid][pSendername], fracname);
    SendClientMessage(params[0], COLOR_ORANGE, string);
    Player[params[0]][pSetLeader] = params[1];
    Player[params[0]][pMember] = params[1];
    Player[params[0]][pRang] = 10;
    SetPlayerToTeamColor(params[0]);
    SetPlayerSkin(params[0], Player[params[0]][pModel]);
    mysql_format(CHDL,query, 512,"UPDATE `"TABLE_ACCOUNT"` SET `setleader`='%d',`model`='%d',`member`='%d',`rang`='%d' WHERE `Name` = '%s'", Player[params[0]][pSetLeader], Player[params[0]][pModel], Player[params[0]][pMember], Player[params[0]][pRang], PlayerName(params[0]));
    mysql_function_query(CHDL, query, false, "","d", params[0]);
   	return true;
}}
