Android 在数据库中插入数据时出错

我试图在本地数据库中保存一些值。该数据库除de ID列外还有3列，分别为：名称、组、顺序

public class TravelOrderDatabaseHelper extends SQLiteOpenHelper {
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("CREATE TABLE " + TABLE_NAME + " (" +
                TravelOrder._ID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
                TravelOrder.NAME + " TEXT NOT NULL, " +
                TravelOrder.GROUP + " TEXT NOT NULL, " +
                TravelOrder.ORDER + " TEXT NOT NULL " +
                ");");
    }

-

在主活动中，要将值保存在数据库中，我使用以下方法：

private void insertTraveler(String name, String group, String order){
    ContentValues newValues = new ContentValues();
    newValues.put(TravelOrder.NAME, name);
    newValues.put(TravelOrder.GROUP, group);
    newValues.put(TravelOrder.ORDER, order);

    getContentResolver().insert(TravelOrderProvider.CONTENT_URI, newValues);
}

但这就是我在日志上看到的：

不能将组用作表名，因为它内置于sqlite的关键字中。。使用不同的关键字组和顺序都是Sqlite中的关键字。此处不能将它们用作列名。更改

public static final String GROUP = "group"; // "group_column"
public static final String ORDER = "order"; // "order_colomn"

---

请参阅列表。

您正在使用sqlite关键字作为列名，即组和顺序

请参阅sqlite中的详细信息组是保留字将其更改为其他TravelOrder.GroupAlOrder是保留关键字order是保留关键字

public static final String GROUP = "group"; // "group_column"
public static final String ORDER = "order"; // "order_colomn"
