This tutorial is about JDBC (Java Database Connectivity), an API provided by Oracle that allows programmers to handle different databases from Java applications: it allows developers to establish connections to databases, defines how a specific client can access a given database, provides mechanisms for reading, inserting, updating and deleting entries of data in a database and takes care of transactions composed of different SQL statements.
In this article we will explain the main JDBC components like Statements, Result Sets or Stored Procedures.
JDBC needs drivers for the different databases that programmers may want to work with; we will explain this in detail and we will provide some examples.
JDBC comes together with Java since the beginning of times; the first release came with the JDK 1.1 on February 1997 and since then, JDBC has been an important part of Java. The main packages where JDBC is contained are Package java.sql and Package javax.sql.
All the information about the last JDBC release (4.2) and its development and maintenance can be found in the JSR 221.
All examples shown in this article have been implemented using Java 8 update 0_25 and the Eclipse SDK version Luna 4.4. At the end of the article you can download all these examples and some more!
