A Quick Look at MySQL 5.4

By Robin Schumacher | April 21, 2009

Although MySQL 5.1 was released in December of 2008, Sun Microsystems isn't wasting any time moving forward with a number of new and exciting enhancements for its next release, MySQL 5.4. The first item of note is that the MySQL Server will be returning to a release early/often paradigm. So, instead of waiting on a full set of previously agreed upon features to be ready, the goal will now be to adhere to time-controlled releases that include all features that are ready by an agreed-upon beta date, with any features not fully 'baked' simply rolling to the next release. This being the case, MySQL 5.4 won't include some large new features like the Falcon transactional storage engine and the new backup utility, but it will include a number of very desirable enhancements that help your database-driven systems scale better and run faster in many cases. Let's take a look at what's included...

Developing Database Applications Using MySQL Connector/C++

By Giri Mandalika | April 15, 2009

The MySQL Connector/C++ provides an object-oriented application programming interface (API) and a database driver for connecting C++ applications to the MySQL Server. Connector/C++ implemented a significant percentage of the industry standard JDBC 4.0 specification in C++ world. This technical article shows the essential steps to build and install MySQL Connector/C++ driver, with simple examples to connect, insert, and retrieve data from a MySQL database. Application developers who are new to MySQL Connector/C++ but not to C++ programming and MySQL database, are the target audience.

Getting started with DTracing MySQL

By Amit Saha | March 5, 2009

DTrace is a dynamic tracing facility built into the Solaris and Open Solaris operating systems and can be used by system administrators and developers alike to observe the runtime behavior of user level programs and of the operating system itself. On one hand, DTrace can be used to identify potential bottlenecks in the running processes on a production system and on the other DTrace can help you understand the runtime behavior of an external program such as MySQL better.

Exception Error Handling Implementation in MySQL/VB.NET Windows Database Applications

By Ernest Bonat, Ph.D. | February 10, 2009

Error handling implementation in Windows database applications is a must for any Application Developer today. The main idea of error handling is to avoid application crashes by finding out the occurred errors and fixing them. Different programming languages have different ways of implementing error handling. Microsoft Visual Basic .NET (VB.NET) is the most common programming language for developing windows database applications today. VB.NET codes are provided in many websites, books and materials without error handling implementation. In this article I would like to introduce you to the basics of error handling implementation in MySQL/VB.NET windows database applications. I’ll be covering structured exception error handling, which was introduced for the first time in VB.NET 2002. I will also go over the latest technologies of disposing unmanaged recourses in .NET Framework with the Using statement. To write exception errors to a log text file, a generic procedure will be developed while MySQL data is loading, inserting, updating and deleting.

By Robin Schumacher | January 26, 2009

Prior to MySQL 5.1, it wasn’t all that easy to find the worst running SQL on a MySQL instance. And truth be told, MySQL still has a ways to go before it’s an effortless process. But, the good news is there are some new aids in MySQL 5.1 and MySQL Enterprise that do make it more efficient to find and troubleshoot bad SQL code that’s hiding inside a MySQL instance. Let’s take a quick tour through these new features and see what help they provide.
