SQLiteOpenHelper的OnCreate上的SQLiteException

Question

我有一个例外：

android.database.sqlite.SQLiteException: near "Login": syntax error (code 1): , while compiling: Login

当我尝试创建新数据库时。

那是我的MainActivity代码，我在其中调用createDataBase：

    public class CreateSQLite extends AsyncTask<Integer, String, Integer> {

    ProgressDialog progress;
    Context context;

    public CreateSQLite(Context context) {
        this.context = context;
    }

    protected void onPreExecute() {


    }

    protected Integer doInBackground(Integer... paramss) {

        SqliteHelper dbHelper = new SqliteHelper(MainActivity.this);
        mDb = openOrCreateDatabase("FManagement.db", Context.MODE_PRIVATE, null);
        dbHelper.onUpgrade(mDb, 4, 5);

        return 0;

    }

    protected void onPostExecute(Integer result) {

        if(progress.isShowing())
            progress.dismiss();
    }
}

这是我的登录表：

public class LoginTable {

public static final String TABLE_LOGIN = "Login";
public static final String COL_USER_ID = "user";
public static final String COL_PASSWORD = "password";
public static final String COL_REMEMBER_PASSWORD = "remember_password";
public static final String COL_LAST_ACCESS = "last_access";

public static final String DB_LOGIN = "CREATE TABLE " + TABLE_LOGIN + "("
        + COL_USER_ID + " TEXT PRIMARY KEY, "
        + COL_PASSWORD + " TEXT, "
        + COL_REMEMBER_PASSWORD + " TEXT, "
        + COL_LAST_ACCESS + " TEXT " + ")";

}

那是我的助手数据库：

     @Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(LoginTable.TABLE_LOGIN);
    db.execSQL(UserTable.TABLE_USER);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS " + LoginTable.TABLE_LOGIN);
    db.execSQL("DROP TABLE IF EXISTS " + UserTable.TABLE_USER);
    onCreate(db);
}

我不太理解该异常，我做错了什么吗？

有人可以帮助我吗？

谢谢！ o /
