python - 如何在 GridDB 数据库容器中检索已删除的行？

Question

我有一个允许您编写 SQL 查询的应用程序，它在我制作的 GridDB 容器上运行它。我测试了部署的应用程序，并以某种方式尝试使用 DELETE 语句从存储数据库的 GridDB 容器中删除前两行，从那时起，这些行就消失了，它们不再出现在应用程序的数据库中. 有没有办法可以从容器或数据库后端再次访问已删除的行？这是后端控制数据库的代码。

        container = gridstore.put_container(conInfo) 
        container.create_index("id", griddb.IndexType.DEFAULT)  
        data = pd.read_csv("dataset.csv")


        # Adding the database
        for i in range(len(data)):
            ret = container.put(data.iloc[i, :])

    except Exception as e:
        print(e)

    # Where the code reads the query from the user
    sql_statement = (f'{query}')
    sql_query = pd.read_sql_query(sql_statement, container)
    # Can I possibly reverse statements?
