To load the class, we are passing className so that the driver can be loaded in to memory.Now let’s talk about the parameters that we pass to the above two steps.This line actually gets the connection to the database if all the parameters are correctly configured and stores it in the connection object which can be used later to execute queries. The next important thing is the line connection = DriverManager.getConnection(URL, user, password).The important things to notice here would be the lineClass.forName(className) which is responsible for loading the driver in to the memory.To connect to a database using JDBC, first we need to load the JDBC driver in to memory and use theĭriverManager to get a connection to database.Go to libraries under Project settings and click on add to locate and add the JDBC jar files to the project. To do this in Intellij, right click on Project folder -> Open module settings, this should open a new window.Locate the JDBC driver jar file and press Open. To do this in eclipse, Right click on Project in package explorer -> Build Path -> Add External Archives.

The next important thing will be to add the JDBC drivers to the build path of the project.

Open your favorite IDE and create a new Java project.

With everything setup for you to connect to database, let’s start the fun by writing code to connect to your data source. Pg_restore -U -d dvdrentals /path/to/dvdrental.tar

Now run the following command to import the database from the downloaded database backup.

To import the sample database, create a database in Postgres by running the following command either in psql or pgAdmin.

If you need data for your Postgres, you can download the DVD rental sample database and import it.

If you're interested in connecting to just one data source, then you only need to set up one of these.

Download and Install Progress DataDirect JDBC drivers for Postgres and Salesforce.

In case you don’t have one, register yourself for one

Have Postgres installed on your machine/server.

We expect you have the following setup before proceeding further with this tutorial. The goal is to demonstrate the simplicity of our Progress DataDirect JDBC drivers for Postgres and Salesforce for connecting and retrieving the data, irrespective of type of the data source.

Running simple SQL queries to fetch dataįor the purpose of this tutorial, we will be using a relational database (Postgres) and SaaS data source (Salesforce) as our data sources.Connecting to your data source using JDBC.The main objectives of this tutorial are to demonstrate: In the first tutorial of the series, we will show you how you can use Progress DataDirect JDBC drivers in your Java application to connect to your database.

To demonstrate this, we have a planned a “JDBC-Revisited” tutorial series of three parts, which covers various concepts from creating a connection, executing simple queries, extracting metadata and DB interoperability features of DataDirect drivers. These drivers, once primarily available for relational databases, are now available for almost any type of data source such as Big Data, No SQL and SaaS.Įven with all these different types of data sources, it’s still easy to connect to and work with them using Progress DataDirect JDBC drivers. JDBC drivers are the most conventional way that many developers use to connect to databases from their Java applications.
