編譯CREATE VIEW時不存在SQLite錯誤列（存在）

我試圖創建一個視圖，但由於某種原因，它給了我一個列不存在的錯誤。這不是我所做的第一個視圖，所有其他人都在工作，表格在那裏，列和所有（我用DBBrowser檢查，除了這一個VIEW不工作）。編譯CREATE VIEW時不存在SQLite錯誤列（存在）

我檢查了我的空白區，這一切都是爲了順序，但有些事情出錯了，我一直在拉我的頭髮，試圖找出什麼。有人可以對此有所瞭解嗎？

logcat的

Caused by: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.jc.pseudocc/com.example.jc.pseudocc.AccountManager}: android.database.sqlite.SQLiteException: no such column: Companies.CompanyID (code 1): , while compiling: CREATE VIEW ViewCompanies AS SELECT Companies.CompanyID AS _id, Payments.GroupID, Payments.PaymentDue, Payments.DateDue FROM Payments JOIN Accounts ON Payments.GroupID = Accounts.AccountID

表

COMPANY

db.execSQL("CREATE TABLE " + COMPANY + " (" + colCompID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
      colCompClass + " TEXT)");

PAYMENTS

db.execSQL("CREATE TABLE " + PAYMENTS + " (" + colPayID + " INTEGER PRIMARY KEY , " + 
      colGroupID + " INTEGER NOT NULL, " + 
      colPayBal + " TEXT, " + 
      colInterest + " TEXT, " + 
      colPayDue + " TEXT, " + 
      colDateDue + " TEXT, " + 
      colPayDate + " TEXT, " + 
      "FOREIGN KEY (" + colGroupID + ") REFERENCES " + ACCOUNTS + " (" + colID + ") ON DELETE CASCADE);");

VIEW

db.execSQL("CREATE VIEW " + viewComps + 
      " AS SELECT " + COMPANY + "." + colCompID + " AS _id," + 
      " " + COMPANY + "." + colCompClass + "," +

      " " + PAYMENTS + "." + colDateDue + "" + 
      " FROM " + PAYMENTS + 
      " JOIN " + ACCOUNTS + " ON " + PAYMENTS + "." + colGroupID + " = " + ACCOUNTS + "." + colID);

應該'」 FROM 「+付款+'是'」 FROM 「+付款+」，「+ COMPANY +'？ – njzk2

我現在在哭，那個時候我不再編碼，因爲我再也不用編寫怪物來睡覺了。謝謝你，我有一種感覺，我錯過了一些東西。將它發佈爲答案，以便我們可以在SO中完成我的第一個愚蠢問題。 – Cytus

在創建視圖，您引用公司和支付。您需要表明，在您的查詢的FROM部分：

更換

" FROM " + PAYMENTS +

與

" FROM " + PAYMENTS + ", " + COMPANY +
