Create a Data Access Object for Outreach.io Data using JDBI


A brief overview of creating a SQL Object API for Outreach.io 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 Outreach.io integrates connectivity to live Outreach.io data in Java applications. By pairing these technologies, you gain simple, programmatic access to Outreach.io data. This article walks through building a basic Data Access Object (DAO) and the accompanying code to read and write Outreach.io data.

Create a DAO for the Outreach.io Accounts 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 MyAccountsDAO { //insert new data into Outreach.io @SqlUpdate("INSERT INTO Accounts (Industry, NumberOfEmployees) values (:industry, :numberOfEmployees)") void insert(@Bind("industry") String industry, @Bind("numberOfEmployees") String numberOfEmployees); //request specific data from Outreach.io (String type is used for simplicity) @SqlQuery("SELECT NumberOfEmployees FROM Accounts WHERE Industry = :industry") String findNumberOfEmployeesByIndustry(@Bind("industry") String industry); /* * close with no args is used to close the connection */ void close(); }

Open a Connection to Outreach.io

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

You must use OAuth to authenticate with Outreach. Set the InitiateOAuth connection property to "GETANDREFRESH". For more information, refer to the OAuth section in the Help documentation.

Built-in Connection String Designer

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

java -jar cdata.jdbc.outreach.jar

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

A connection string for Outreach.io will typically look like the following:

jdbc:outreach: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:outreach:InitiateOAuth=GETANDREFRESH"); MyAccountsDAO dao = dbi.open(MyAccountsDAO.class); //do stuff with the DAO dao.close();

Read Outreach.io Data

With the connection open to Outreach.io, simply call the previously defined method to retrieve data from the Accounts entity in Outreach.io.

//disply the result of our 'find' method String numberOfEmployees = dao.findNumberOfEmployeesByIndustry("Textiles"); System.out.println(numberOfEmployees);

Write Outreach.io Data

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

//add a new entry to the Accounts entity dao.insert(newIndustry, newNumberOfEmployees);

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