没有这样的表问题

Question

另一个涉及SQLite方面的Java问题。

我已经运行了我的应用程序，一切都很好，直到我来添加插入的数据为止。 我在Log cat '12 -31 22：54：51.133：I / Database（273）：sqlite return：error code = 1，msg = no such table：peopleTable'的日志猫中遇到错误。 显然，这导致了我无法使用我的insert方法添加到数据库的事实。

我尝试重命名数据库，我的表create语句或onCreate / Upgrade方法看不到任何错误。

这是代码：

码：

public void onCreate(SQLiteDatabase db) {


        db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" +
                KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                KEY_NAME + " TEXT NOT NULL, " +
                KEY_HOTNESS + "TEXT NOT NULL);");


    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

        db.execSQL("DROP TABLE IF EXCISTS" + DATABASE_TABLE);
        onCreate(db);
    }

和logcat：

12-31 22:54:51.158: E/Database(273): Error inserting persons_hotness=5 persons_name=F

Answer 1

KEY_HOTNESS + "TEXT NOT NULL);");

看起来可能会引起问题。 像表声明中的其他列一样，两个字符串值之间是否有空格（ " " ）？

Answer 2

将EXCISTS更改为EXISTS ，它将起作用（或者至少可以解决您的问题之一）
;）

Answer 3

泰（Ty）为您提供帮助。 调整为您看到的错误的组合，以及我在upGrade上使用相同数据库版本的事实。
