JDBI からGoogle Ads Data のデータアクセスオブジェクトを作成

JDBI でGoogle Ads data 用のSQL オブジェクトAPIを作成する方法を概説します。

JDBI は、Fluent スタイルとSQL オブジェクトスタイルという2つの異なるスタイルAPI を公開する、Java 用のSQL コンビニエンスライブラリです。CData JDBC Driver for Google Ads は、Java アプリケーションとリアルタイムGoogle Ads data のデータ連携を実現します。これらの技術を組み合わせることによって、Google Ads data へのシンプルなコードアクセスが可能になります。ここでは、基本的なDAO(Data Access Object )とそれに付随するGoogle Ads data の読み書きのためのコードの作成について説明します。

Google Ads CampaignPerformance Entity のDAO を作成

The interface below declares the desired behavior for the SQL object to create a single method for each SQL statement to be implemented.

public interface MyCampaignPerformanceDAO { //request specific data from Google Ads (String type is used for simplicity) @SqlQuery("SELECT Clicks FROM CampaignPerformance WHERE Device = :device") String findClicksByDevice(@Bind("device") String device); /* * close with no args is used to close the connection */ void close(); }

Google Ads への接続を開く

Collect the necessary connection properties and construct the appropriate JDBC URL for connecting to Google Ads.

Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

In addition to the OAuth values, specify the DeveloperToken and ClientCustomerId.

See the "Getting Started" chapter of the help documentation for a guide to using OAuth.


For assistance in constructing the JDBC URL, use the connection string designer built into the Google Ads JDBC Driver.Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.googleads.jar

Fill in the connection properties and copy the connection string to the clipboard.

A connection string for Google Ads will typically look like the following:


Use the configured JDBC URL to obtain an instance of the DAO interface.The particular method shown below will open a handle bound to the instance, so the instance needs to be closed explicitly to release the handle and the bound JDBC connection.

DBI dbi = new DBI("jdbc:googleads:DeveloperToken=MyDeveloperToken;ClientCustomerId=MyClientCustomerId;InitiateOAuth=GETANDREFRESH"); MyCampaignPerformanceDAO dao =; //do stuff with the DAO dao.close();

Google Ads Data について

With the connection open to Google Ads, simply call the previously defined method to retrieve data from the CampaignPerformance entity in Google Ads.

//disply the result of our 'find' method String clicks = dao.findClicksByDevice("'Mobile devices with full browsers'"); System.out.println(clicks);

Since the JDBI library is able to work with JDBC connections, you can easily produce a SQL Object API for Google Ads by integrating with the CData JDBC Driver for Google Ads.Download a free trial and work with live Google Ads data in custom Java applications today.
