How-To: Guide to Database Migration from Microsoft SQL Server using MySQL Workbench

MySQL Workbench 5.2.41 introduces a new Migration Wizard module. This module allows you to easily and quickly migrate databases from various RDBMS products to MySQL. In this initial version, migrations from Microsoft SQL Server are supported, but it should also be possible to migrate from most ODBC capable RDBMS as well, using its generic RDBMS support. Additionally, you can use it to perform MySQL to MySQL database copies, which can be used for tasks such as copying a database across servers or migrating data across different versions of MySQL.

So let’s get our hands dirty and run through the Migration Wizard in order to migrate a Microsoft SQL Server database to MySQL. In the rest of this post I assume that you have:

  • A running SQL Server instance in which you have proper access to the database you want to migrate. (I’ll call this database from now on the source database). I have a remote SQL Server 2000 instance …

MySQL Connector/Net 6.6.0 Alpha has been released

MySQL Connector/Net 6.6.0, a new version of the all-managed .NET driver for MySQL has been released.  This is the first of two alpha releases intended to introduce users to the new features in the release.  This release is not feature complete and there are significant limitations but it should be stable enough for users to understand the new features and how we expect them to work.  As is the case with all non-GA releases, it should not be used in any production environment.  It is appropriate for use with MySQL server versions 5.0-5.6

It is now available in source and binary form from and mirror sites (note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download …

Living With Linux

I learned how to use a computer on DOS and Windows. My first programming projects were written in QBASIC and my first Web applications were written in VB using ASP on Windows 2000. The first job where I made decent money was developing a SQL Server-based application. I bought my first car, an engagement ring, and a honeymoon with money from making software on Windows. Needless to say, I found a lot of intellectual and financial fulfillment from Windows over the years.

That first real job also allowed me flexibility in what technology I could employ, and I helped implement a features using Redis on top of Ubuntu. This was a fun time, because my company basically paid me to study a new technology and to gain experience using it. On my own, I began to use Linux and to embrace open-source ideas, one of which is that the consumer is also the producer. I changed my mindset about what it means to use software: for open-source projects, it often …

Using Windows profiler with mysqld

My colleague who is a Windows guru taught me how to do very basic things with the Windows profiler. While this stuff is primitive, the sad truth is that many people don’t know even this little about Windows, me including. I’ll keep the hints here, and hopefully will learn more with time.

  • Use RelWithDebInfo builds, Debug build will screw the picture, it will tell you _db_enter is the most expensive function;
  • Start mysqld;
  • Use x64 VS command prompt:

Start => All Programs => MS Visual Studio 2010 => Visual Studio Tools => Visual Studio x64 Win64 command prompt

  • Set _NT_SYMBOL_PATH to the package bin directory, so mysqld.pdb can be found, and start the IDE:

set _NT_SYMBOL_PATH=... && devenv.exe

  • In the VS command prompt, run

vsperfcmd /start:sample …

ZFS: could have been the future of UNIX Filesystems

There was a point a few years ago where Sun could have had the next generation UNIX filesystem. It was in Solaris (and people were excited), there was a port to MacOS X (that was quite exciting for people) and there was a couple of ways to run it on linux (and people were excited). So… instead of the fractured landscape of ext3, HFS+ and (the various variations of) UFS we could have had one file system that was common between all of the commonly used UNIX-like variants. Think of being able to use a file system on a removable drive that isn’t FAT and being able to take it from machine to machine (well… Windows would be a problem, but it always is).

There was some really great work done in OpenSolaris with integration between the file manager and ZFS snapshots (a slider bar to browse the history of a directory, an idea I’ve championed for over a decade now, although the Sun implementation was likely completely independently developed). …

Mixed signals in IT’s great war over IP

Recent news that Microsoft and Barnes & Noble agreed to partner on the Nook e-reader line rather than keep fighting over intellectual property suggests the prospect of more settlement and fewer IP suits in the industry. However, the deal further obscures the blurry IP and patent landscape currently impacting both enterprise IT and consumer technology.

It is good to see settlement — something I’ve been calling for, while also warning against patent and IP aggression. However, this settlment comes from the one conflict in this ongoing war that was actually shedding some light on the matter, rather than further complicating it.
