Introduction

Using Eclipse, we'll develop an example application that will document key structures, and demonstrate several API calls. This article will also cover configuring Ubuntu and Eclipse for MySQL client development. Let's get going...

Ubuntu

You'll need to install the build-essential, Eclipse and the Eclipse CDT packages:





MySQL

In order to develop an application with the API, you'll need libmysqlclient and all the header files installed.

Is your MySQL server doing an extra index scan on queries that need to check a key for matches or NULL? It's easy for this to happen accidentally, but it's also easy to fix, especially in MySQL 5.0 and up. Here's how.

With some effort just before my holiday, I have managed to complete the release of the next version of MyBS, the BLOB streaming engine for MySQL.

This version includes all the basic functionality required to stream BLOB data in and out of MySQL tables.

The main features are:

• Uploading of BLOB data directly into the database using HTTP PUT or GET methods.
  
• Downloaded of BLOB data directly from the database using HTTP GET.
  
• BLOB size may exceed 4GB - theoretical BLOB size limit of 256 Terabytes.
  
• BLOBs are stored in a repository which manages references from other storage engine tables.
  
• BLOBs are referenced by a URL.
  
• URLs referencing BLOBs in the repository have a unique access code, for security.
  
• The theoretical maximum repository size is 4 Zettabytes (2^72 bytes) per …

It is true you might be better of being unaware about problems, because in this case you might not run into them
Just couple of days ago Kaj Arno told me there are issues reported with SHOW PROFILE patch available in latest MySQL Community Edition and I've been troubleshooting customer affected by one of these very issues today.

Of course you’ve heard about the fabulous pybots project, where community members have a distributed network of computers continuously testing every change in the development version of python against the development version of many different python applications. This ensures that any compatibility problems are caught early, well before the next version of python is released.

I’ve just about finished getting storm, the newly open sourced python object-relational mapper that we are using with Launchpad and Landscape, added into the pybots test suite. Just need to finish reading through an 18MB test log to figure out what I did wrong in the test script for the psycopg2 installation, and we should be all set, with storm being tested against MySQL, Postgresql, and SQLite. Rumour has it that Firebird support is coming soon (perhaps even …
