Which method can be used to retrieve query results in ABAP Database Connectivity?

The method used to retrieve query results in ABAP Database Connectivity (ADBC) is NEXT_PACKAGE. This method is specifically designed to handle the retrieval of data in a paged fashion when working with result sets. It allows the application to fetch data in sequential chunks, which is particularly useful when dealing with large datasets that could exceed memory limitations if loaded all at once.

In ADBC, NEXT_PACKAGE is called after an initial query execution to continue retrieving rows from the result set until there are no more rows available. This method effectively optimizes the reading of data by controlling memory usage and allowing for efficient processing of the results.

The other options, while related to data handling in ABAP or ADBC, do not specifically focus on the retrieval of query results. For example, SET_PARAM_TABLE is used to set parameters for a query, GET_RESULTS is not a standard ADBC method, and EXECUTE_QUERY is used for executing the query itself rather than fetching the results.
