Below code should work perfectly fine.

PHP код:

CMD:setlevel(playerid, params[])
{
    //check if the player is a admin
    LevelCheck(playerid, 5);
    new target, level;
    if(sscanf(params, "ui", target, level)) return SendClientMessage(playerid, COLOR_THISTLE, "USAGE: /setlevel [player] [level]");
    if(! IsPlayerConnected(target)) return SendClientMessage(playerid, COLOR_FIREBRICK, "ERROR: The specified player is not conected.");
    if(GetPlayerGAdminLevel(playerid) < GetPlayerGAdminLevel(target)) return SendClientMessage(playerid, COLOR_FIREBRICK, "ERROR: You cannot use this command on higher level admin.");
    if(level < 0 || level > MAX_ADMIN_LEVELS) return SendClientMessage(playerid, COLOR_FIREBRICK, "ERROR: Invalid level, mus be b/w 0-"#MAX_ADMIN_LEVELS".");
    if(level == GetPlayerGAdminLevel(target)) return SendClientMessage(playerid, COLOR_FIREBRICK, "ERROR: Player is already of that level.");
    new string[144];
    if(GetPlayerGAdminLevel(playerid) < level)
    {
        GameTextForPlayer(target, "~g~~h~~h~~h~Promoted", 5000, 1);
        format(string, sizeof(string), "You have been promoted to admin level %i by %s[%i], Congratulation.", level, ReturnPlayerName(playerid), playerid);
        SendClientMessage(target, COLOR_DODGER_BLUE, string);
        format(string, sizeof(string), "You have promoted %s[%i] to admin level %i.", ReturnPlayerName(target), target, level);
        SendClientMessage(playerid, COLOR_DODGER_BLUE, string);
    }
    else if(GetPlayerGAdminLevel(playerid) > level)
    {
        GameTextForPlayer(target, "~r~~h~~h~~h~Demoted", 5000, 1);
        format(string, sizeof(string), "You have been demoted to admin level %i by %s[%i], Sorry.", level, ReturnPlayerName(playerid), playerid);

    }
    PlayerPlaySound(target, 1057, 0.0, 0.0, 0.0);
    PlayerPlaySound(playerid, 1057, 0.0, 0.0, 0.0);
    new key = DB::RetrieveKey(gGlobal[s_usertable], "username", ReturnPlayerName(target)); // It was "playerid" should be "target"
    DB::SetIntEntry(gGlobal[s_usertable], key, "admin", level);
        gUser[target][u_admin] = level;
    return 1;
