Create a Data Access Object for SAP Concur Data using JDBI

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

Create a DAO for the SAP Concur Departments 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 MyDepartmentsDAO { //insert new data into SAP Concur @SqlUpdate("INSERT INTO Departments (Id, OfficeId) values (:id, :officeId)") void insert(@Bind("id") String id, @Bind("officeId") String officeId); //request specific data from SAP Concur (String type is used for simplicity) @SqlQuery("SELECT OfficeId FROM Departments WHERE Id = :id") String findOfficeIdById(@Bind("id") String id); /* * close with no args is used to close the connection */ void close(); }

Open a Connection to SAP Concur

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

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

Built-in Connection String Designer

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

java -jar cdata.jdbc.sapconcur.jar

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

A connection string for SAP Concur 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:sapconcur:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;InitiateOAuth=GETANDREFRESH"); MyDepartmentsDAO dao =; //do stuff with the DAO dao.close();

Read SAP Concur Data

With the connection open to SAP Concur, simply call the previously defined method to retrieve data from the Departments entity in SAP Concur.

//disply the result of our 'find' method String officeId = dao.findOfficeIdById("1668776136772254"); System.out.println(officeId);

Write SAP Concur Data

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

//add a new entry to the Departments entity dao.insert(newId, newOfficeId);

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