Class SqlTranslationServiceClient (0.39.0)

GitHub RepositoryProduct ReferenceREST Documentation

Service Description: Provides other SQL dialects to GoogleSQL translation operations.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (SqlTranslationServiceClient sqlTranslationServiceClient =
     SqlTranslationServiceClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   TranslateQueryRequest.SqlTranslationSourceDialect sourceDialect =
       TranslateQueryRequest.SqlTranslationSourceDialect.forNumber(0);
   String query = "query107944136";
   TranslateQueryResponse response =
       sqlTranslationServiceClient.translateQuery(parent, sourceDialect, query);
 }
 

Note: close() needs to be called on the SqlTranslationServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
MethodDescriptionMethod Variants

TranslateQuery

Translates input queries from source dialects to GoogleSQL.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • translateQuery(TranslateQueryRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • translateQuery(LocationName parent, TranslateQueryRequest.SqlTranslationSourceDialect sourceDialect, String query)

  • translateQuery(String parent, TranslateQueryRequest.SqlTranslationSourceDialect sourceDialect, String query)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • translateQueryCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of SqlTranslationServiceSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SqlTranslationServiceSettings sqlTranslationServiceSettings =
     SqlTranslationServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SqlTranslationServiceClient sqlTranslationServiceClient =
     SqlTranslationServiceClient.create(sqlTranslationServiceSettings);
 

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SqlTranslationServiceSettings sqlTranslationServiceSettings =
     SqlTranslationServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 SqlTranslationServiceClient sqlTranslationServiceClient =
     SqlTranslationServiceClient.create(sqlTranslationServiceSettings);
 

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SqlTranslationServiceSettings sqlTranslationServiceSettings =
     SqlTranslationServiceSettings.newHttpJsonBuilder().build();
 SqlTranslationServiceClient sqlTranslationServiceClient =
     SqlTranslationServiceClient.create(sqlTranslationServiceSettings);
