java - 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，一切正常，直到我添加插入的数据。我在“12-31 22:54:51.133: I/Database(273): sqlite returned: error code = 1, msg = no such table: peopleTable”的日志猫中收到错误。这显然导致我无法使用我的插入方法添加到数据库。

我已经尝试重命名数据库，我看不到我的表创建语句或我的 onCreate/Upgrade 方法有任何问题。

代码如下:

代码:

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);");

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