November 6, 2023

In this PostgreSQL JDBC section, you will learn how to interact with the PostgreSQL databases using Java JDBC driver.

JDBC is the core API of Java that provides a standard interface to SQL-compliant databases, especially PostgreSQL.

PostgreSQL JDBC Tutorial

First, we start the tutorials by showing you how to download the PostgreSQL JDBC driver and set up an environment for developing Java applications that connect to a PostgreSQL database server.

Then, we show you how to connect the PostgreSQL database server and perform various operations such as querying, inserting, updating, and deleting data. We also cover the database transaction in PostgreSQL via JDBC API.

To follow the tutorials, you need to have basic knowledge of Java programming language and know how to interact with PostgreSQL database server such as connecting to the PostgreSQL database server and querying data using the SELECT statement. You are not required to have the JDBC knowledge to understand the code because we will explain each line of code in detail.

You can follow the tutorials in sequence or you can jump directly to the interested tutorial based on the solution that you are looking for.

For the demonstration purpose, we will use the dvdrental sample database. It is faster and easier to follow the tutorials if you download and load this sample database into your PostgreSQL database server.
