我有一個模型，並具有相同的數據庫表。兩者都是同步的。我在另一臺服務器上有另一個數據庫，我正在使用相同的模型，但是不同的dbContext。列Npgsql錯誤
我的系統是什麼它檢查本地dbcontext並獲取一些行，然後它檢查具有唯一ID的同一行。但是，當它增加了在表中的行它給了我，我不知道什麼是錯的我的表有作爲模型
這裏宣佈同列
ERROR: 42703: column "etrue" does not exist
錯誤 是我的模型

string ecode = CardsData[i].ecode;
using (CacsCentralContext CacsCentral = new CacsCentralContext())
{
IList<Cards> CentralCards = (from cards in CacsCentral.Cards

select cards).ToList();
if (CentralCards.Count != 0)

我不知道爲什麼它被放在鄂中列的值
首先，我沒有在你的模型類中看到「etrue」屬性，所以目前還不清楚爲什麼你的代碼會生成查詢來使用它。其次，該錯誤來自數據庫 - 該列不在一個（或兩個）表中。如果代碼中的模型應該使用該列，則需要將其添加到數據庫中。 – yieldsfalsehood
thanx爲您的答覆。以及在這兩個表中沒有這樣的列我不明白什麼似乎是問題.. –
數據庫錯誤應該與產生錯誤的查詢。如果您的客戶沒有向您顯示該查詢，您可以打開數據庫日誌並在那裏查看。 – yieldsfalsehood
