Java PostgreSQL Tutorial

This is a Java tutorial for the PostgreSQL database. It covers the basics of PostgreSQL programming with Java.

What is PostgreSQL?

PostgreSQL is a general-purpose and object-relational database management system, the most advanced open-source database system. PostgreSQL was developed based on POSTGRES 4.2 at Berkeley Computer Science Department, University of California.
PostgreSQL was designed to run on UNIX-like platforms. However, PostgreSQL was then also designed to be portable so that it could run on various platforms such as Mac OS X, Solaris, and Windows.

PostgreSQL features highlights

PostgreSQL has many advanced features that other enterprise database management systems offer, such as:
The recent versions of PostgreSQL support the following features:
  • Native Microsoft Windows Server version
  • Tablespaces
  • Point-in-time recovery

Technologies used

We use below technologies in this tutorial:
  • JDK - 1.8 or later
  • PostgreSQL- 42.2.9
  • IDE - Eclipse Neon
  • JDBC - 4.2

Download PostgreSQL JDBC Driver

To connect to the PostgreSQL database server from a Java program, you need to have a PostgreSQL JDBC driver. You can download the latest version of the driver on the postgresql.org website via the download page.
Add the PostgreSQL JDBC driver jar file to the project classpath.
For maven users:
<!-- https://mvnrepository.com/artifact/org.postgresql/postgresql -->
<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>42.2.9</version>
</dependency>
For Gradle users:
// https://mvnrepository.com/artifact/org.postgresql/postgresql
compile group: 'org.postgresql', name: 'postgresql', version: '42.2.9'

Java PostgreSQL Tutorials and Examples

  • Java - JDBC PostgreSQL Batch Insert Example In this tutorial, we will discuss the JDBC Batch insert example in the PostgreSQL database. Sometimes we need to run bulk queries of a similar kind for a database, for example, loading data from CSV files to relational database tables.
