Use GetStatementResult
with an Amazon SDK
The following code examples show how to use GetStatementResult
.
Action examples are code excerpts from larger programs and must be run in context. You can see this action in
context in the following code example:
- Java
-
- SDK for Java 2.x
-
Check the statement result.
/**
* Asynchronously retrieves the results of a statement execution.
*
* @param statementId the ID of the statement for which to retrieve the results
* @return a {@link CompletableFuture} that completes when the statement result has been processed
*/
public CompletableFuture<Void> getResultsAsync(String statementId) {
GetStatementResultRequest resultRequest = GetStatementResultRequest.builder()
.id(statementId)
.build();
return getAsyncDataClient().getStatementResult(resultRequest)
.handle((response, exception) -> {
if (exception != null) {
logger.info("Error getting statement result {} ", exception.getMessage());
throw new RuntimeException("Error getting statement result: " + exception.getMessage(), exception);
}
// Extract and print the field values using streams if the response is valid.
response.records().stream()
.flatMap(List::stream)
.map(Field::stringValue)
.filter(value -> value != null)
.forEach(value -> System.out.println("The Movie title field is " + value));
return response;
}).thenAccept(response -> {
// Optionally add more logic here if needed after handling the response
});
