JDBI からMarketo Data のデータアクセスオブジェクトを作成

JDBI でMarketo 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 Marketo は、Java アプリケーションとリアルタイムMarketo 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、Marketo 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Marketo 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。

Marketo Leads 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 MyLeadsDAO { //insert new data into Marketo @SqlUpdate("INSERT INTO Leads (Country, AnnualRevenue) values (:country, :annualRevenue)") void insert(@Bind("country") String country, @Bind("annualRevenue") String annualRevenue); //request specific data from Marketo (String type is used for simplicity) @SqlQuery("SELECT AnnualRevenue FROM Leads WHERE Country = :country") String findAnnualRevenueByCountry(@Bind("country") String country); /* * close with no args is used to close the connection */ void close(); }

Marketo への接続を開く

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

Both the REST and SOAP APIs are supported and can be chosen by using the Schema property.

For the REST API: The OAuthClientId, OAuthClientSecret, and RESTEndpoint properties, under the OAuth and REST Connection sections, must be set to valid Marketo user credentials.

For the SOAP API: The UserId, EncryptionKey, and SOAPEndpoint properties, under the SOAP Connection section, must be set to valid Marketo user credentials.

See the "Getting Started" chapter of the help documentation for a guide to obtaining these values.


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

java -jar cdata.jdbc.marketo.jar

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

A connection string for Marketo 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:marketo:Schema=REST;RESTEndpoint=;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;"); MyLeadsDAO dao =; //do stuff with the DAO dao.close();

Marketo Data について

With the connection open to Marketo, simply call the previously defined method to retrieve data from the Leads entity in Marketo.

//disply the result of our 'find' method String annualRevenue = dao.findAnnualRevenueByCountry("U.S.A."); System.out.println(annualRevenue);

Marketo Data の書き方

It is also simple to write data to Marketo, using the previously defined method.

//add a new entry to the Leads entity dao.insert(newCountry, newAnnualRevenue);

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