A JDBC Tutorial


A JDBC tutorial is an excellent way to learn the basics of this powerful programming language. This article covers the Java JDBC API, Type IV driver, PreparedStatement, and Spring Transaction Management. The source code is available on GitHub. In addition, the tutorial includes examples and code that you can use to test out the various features of the library.


The Java JDBC API is an API that allows you to communicate with a database using Java. You can use the API to retrieve and modify data stored in the database, which can be very useful if you need to retrieve information from a database on a regular basis. In this tutorial, you’ll learn the basics of the JDBC API and the basics of selecting data from the database.

The JDBC API works with any relational database and provides a standard interface. It can be used in a two-tier or three-tier application, and has the added advantage of being platform-independent.

Type IV driver

If you are using a JDBC Type IV driver, you will need to know some key properties. One of these properties is maxPoolSize, which sets the maximum number of physical connections that can be used simultaneously. This includes both free connections and ones that are in use. If this property is exceeded, the Type 4 driver will throw an SQLException and send a message saying “Maximum pool size reached.”

The second parameter, character-set, corresponds to the character-set of the column. For example, the following method invocation sets column one of stmt to the String “abcd”.


A PreparedStatement is a subinterface of Statement and contains a pre-compiled SQL query. It is a more convenient way to make a query than a traditional SQL statement. The pre-compilation of a PreparedStatement also prevents SQL injection. A PreparedStatement can be supplied with several different parameters that make it easier to customize the query.

In a parameterized query, you can use a PreparedStatement instead of using the standard Statement interface. It improves performance because the query is compiled once, instead of many times. The PreparedStatement interface includes methods for inserting, updating, and deleting data.

The PreparedStatement object can be cached by the JDBC driver. This allows for reuse of a prepared SQL statement across several Java applications. This makes query execution faster and more secure.

Spring Transaction Management

Spring Transaction Management is the name given to the method that Spring uses to manage database connections. It is similar to the CMT used by EJB. This method is used when you need to make changes to a data source and you want the changes to persist for a certain amount of time. It is often used to deal with SQL errors and business logic errors.

In this Spring tutorial, I’ll discuss Spring transaction management and other Spring libraries. You will find that the basics of JDBC are the same, so you’ll be able to apply them across all these libraries. Understanding how these libraries work will be important when creating complex enterprise applications. I’d like to acknowledge Andreas Eisele and Ben Horsfield for their comments on an early version of this guide.

ODBC bridge

The ODBC bridge is one of the key components of a JDBC program. It allows you to connect to any ODBC data source from Java applications. It can also be used to develop custom Java solutions and BI & analytics tools. The CData JDBC-ODBC bridge is fully compatible with both Java development environments and ODBC databases.

The JDBC-ODBC bridge supports many features from the JDBC 2.0 standard, including batch updates and scrollable cursors. It also includes most of the features needed for a J2EE compatible JDBC driver, such as sample implementations of DataSource and ConnectionPoolDataSource classes. It also offers additional robustness and reliability checks.
