| <div class="block">Represents a result of query execution. It potentially contain a mix of update counts |
| and lists of selected values. Provides API somewhat similar to java.util.Iterator or |
| java.sql.ResultSet for scanning through the individual results. |
| <p> |
| An example of iterating through a response: |
| </p> |
| |
| <pre> |
| QueryResponse response = context.performGenericQuery(query); |
| for (response.reset(); response.next();) { |
| if (response.isList()) { |
| List list = response.currentList(); |
| // ... |
| } |
| else { |
| int[] updateCounts = response.currentUpdateCount(); |
| // ... |
| } |
| } |
| </pre> |
| |
| <p> |
| In case the structure of the result is known, and only a single list or an update count |
| is expected, there is a simpler API to access them: |
| </p> |
| |
| <pre> |
| QueryResponse response = context.performGenericQuery(query); |
| List list = response.firstList(); |
| int[] count = response.firstUpdateCount(); |
