Create a Data Access Object for Google Ads Data using JDBI


A brief overview of creating a SQL Object API for Google Ads data in JDBI.

JDBI is a SQL convenience library for Java that exposes two different style APIs, a fluent style and a SQL object style. The CData JDBC Driver for Google Ads integrates connectivity to live Google Ads data in Java applications. By pairing these technologies, you gain simple, programmatic access to Google Ads data. This article walks through building a basic Data Access Object (DAO) and the accompanying code to read Google Ads data.

Create a DAO for the Google Ads CampaignPerformance Entity

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(); }

Open a Connection to Google Ads

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.

Built-in Connection String Designer

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:

jdbc:googleads:DeveloperToken=MyDeveloperToken;ClientCustomerId=MyClientCustomerId;InitiateOAuth=GETANDREFRESH

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 = dbi.open(MyCampaignPerformanceDAO.class); //do stuff with the DAO dao.close();

Read Google Ads Data

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.
