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

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

PCA Sales MasterSms 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 MyMasterSmsDAO { //insert new data into PCA Sales @SqlUpdate("INSERT INTO MasterSms (SyohinMei, SyohinMei) values (:syohinMei, :syohinMei)") void insert(@Bind("syohinMei") String syohinMei, @Bind("syohinMei") String syohinMei); //request specific data from PCA Sales (String type is used for simplicity) @SqlQuery("SELECT SyohinMei FROM MasterSms WHERE SyohinMei = :syohinMei") String findSyohinMeiBySyohinMei(@Bind("syohinMei") String syohinMei); /* * close with no args is used to close the connection */ void close(); }

PCA Sales への接続を開く

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

PCA Sales uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with PCA Sales. See the Getting Started section of the help documentation for an authentication guide.


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

java -jar cdata.jdbc.pcasales.jar

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

A connection string for PCA Sales 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:pcasales:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;ProductCode=MyProductCode;ApiVersion=V1;DataCenter=DataCenterName;DefaultDataArea=MyDefaultDataArea;InitiateOAuth=GETANDREFRESH"); MyMasterSmsDAO dao =; //do stuff with the DAO dao.close();

PCA Sales Data について

With the connection open to PCA Sales, simply call the previously defined method to retrieve data from the MasterSms entity in PCA Sales.

//disply the result of our 'find' method String syohinMei = dao.findSyohinMeiBySyohinMei("Syohin"); System.out.println(syohinMei);

PCA Sales Data の書き方

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

//add a new entry to the MasterSms entity dao.insert(newSyohinMei, newSyohinMei);

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