编译CREATE VIEW时不存在SQLite错误列（存在）

我试图创建一个视图，但由于某种原因，它给了我一个列不存在的错误。这不是我所做的第一个视图，所有其他人都在工作，表格在那里，列和所有（我用DBBrowser检查，除了这一个VIEW不工作）。编译CREATE VIEW时不存在SQLite错误列（存在）

我检查了我的空白区，这一切都是为了顺序，但有些事情出错了，我一直在拉我的头发，试图找出什么。有人可以对此有所了解吗？

logcat的

表

COMPANY

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

应该'” FROM “+付款+'是'” FROM “+付款+” ，“+ COMPANY +'？ – njzk2

我现在在哭，那个时候我不再编码，因为我再也不用编写怪物来睡觉了。谢谢你，我有一种感觉，我错过了一些东西。将它发布为答案，以便我们可以在SO中完成我的第一个愚蠢问题。 – Cytus

在创建视图，您引用公司和支付。您需要表明，在您的查询的FROM部分：

更换

" FROM " + PAYMENTS +

与

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