Nil value fetched from mysql despite the data written there

[Miki12]

The value always comes out nil, despite the existence of data in MySQL.

 

     local Pierwsza = exports.DB2:pobierzTabeleWynikow("SELECT `characterName` FROM `postacie` WHERE `characterID`=?", 1)
    for i,v in ipairs(Pierwsza) do
        Dane1 = v.Pierwsza
    end

     local Druga = exports.DB2:pobierzTabeleWynikow("SELECT `characterName` FROM `postacie` WHERE `characterID`=?",2)
    for i,v in ipairs(Druga) do
        Dane2 = v.Druga
    end

     local Trzecia = exports.DB2:pobierzTabeleWynikow("SELECT `characterName` FROM `postacie` WHERE `characterID`=?",3)
    for i,v in ipairs(Trzecia) do
        Dane3 = v.Trzecia
    end

 

Dane1 ,Dane2 and Dane3 = nil

local Pierwsza = exports.DB2:pobierzTabeleWynikow("SELECT * FROM `postacie` WHERE `characterID`=?", 1);
if #Pierwsza > 0 then
    for i,v in ipairs(Pierwsza) do
        Dane1 = v["characterName"]
        outputChatBox(Dane1)
    end
  end
