這是我的DB：當我更新時，我得到一個成功的消息，但沒有任何變化。我做錯了什麼？
表：Terras_Sico
列---------------類型--------------空
id ---------------------- int（11）-----------沒有
nome ------ ----------- varchar（250）---否
preco_publico -------十進制（10,2） - 否
imagem --------- ------ varchar（250） - 否
nota_prova ----------- varchar（250） - 否
produtor_enologo --- varchar（250） - 否
ano --------------------- varchar（250） - 否
tipo ------------- --------- VARCHAR（250）
這是我的代碼：

有了這樣_問題： 「爲什麼沒有這個代碼工作_/_？」 爲什麼我得到這個錯誤「_很難爲在這種情況下，你應該包括所需的行爲，如果可能的話，包括一個[最小，完整和可驗證的例子]（http://stackoverflow.com/help/mcve） – lealceldeiro
對不起，我 所以我需要幫助，因爲我的更新說明了它，但它不會改變任何東西。我是否必須創建一個新帖子，或者它可以在這個嗎？ –
當然，你可以編輯自己的帖子。您無需發表其他問題。 – lealceldeiro
