In response to Monty Taylor's blog post ...I am the culprit for the content of plugin.h which has the comment "the following declarations are for internal use only" which was introduced into the MySQL server codebase a couple of years ago.Unfortunately, I had to work with the limitations of the C programming language and its preprocessor so to achieve a solution which behaved as if it had the

What or who is Amira?Well... Many would know Amira is to David as My is to Monty.Amira also has all the same letters as Maria, except that it is in PDP "middle-endian" byte order.It is also the codename of a little known project while I was at MySQL: Soon after Oracle acquired Innobase OY, the powers that be at MySQL did not want to solely rely on InnoDB (or BerkeleyDB) as a transactional data

A whole bunch of people have successfully written plugins for MySQL using the plug-in framework which first appears in MySQL 5.1. On the whole, the simple examples work great, as long as all your code is in one directory. Here is a helpful tip...Inside the plug.in file, you can use MYSQL_PLUGIN_DIRECTORY_<FOO> as an alias to the directory in which your plug.in is located within, where FOO is the

I have merged the code from the mysql-5.1 launchpad repository which should put this repository up to the recent 5.1.28-rc version. You can examine the source repository here.On a related note, had a brief email exchange with Eric Herman and so I hope that there will be time for him to do some work to complete the support for Java stored routines.

In case you are processing and working with geospatial data on MySQL, you may be interested in the following UDF (plugin) for MySQL 5.1: Koji Okumura from Oki Labs Japan has ported two functions from PostGIS into a MySQL UDF:

• distance_sphere(point, point): Returns linear distance in meters between two lat/lon points. Uses a spherical earth and radius of 6370986 meters. Faster than distance_spheroid(), but less accurate. Only implemented for points
• distance_spheroid(point, …

Some weeks ago there was a request about adding a feature that keeps (or gets) datatypes of colums, which are connected via foreign keys, in sync. While we have added this to our ToDo list, I thought of doing some simple LUA exercises to give the user at least a funtion to check if the FKs in the model all have columns with matching datatypes.
As it turned out such tasks can be done quite easily using our GRT-shell. And by writing some functions you can add features to Workbenchs interface.

To get in touch with the shell/GRT environment inside Workbench click the tiny black prompt-window-icon in the top right area of workbench (or choose ‘View->Advanced->GRT Shell’ from the main menu).  Some items in the UI are swapped/added: the sidebar on the right side gets a new tab named ‘GRT Shell’ featuring some more tool-panes (GRT Tree, Modules, Inspector) and on the bottom part of the main window - where the editors …

I have updated the Forge page for the External Language Stored Procedures, adding a PDF for the slides used in the presentation and a link to a video of the presentation for those people who missed it. It was quite unfortunate that at the Conference, there were two presentations occurring at the same time which discussed the topic of UDF/Stored Procedures so I am sure that there are people who

The Lua plugin support has been finally fixed and will be working in the next release. Together with a few other improvements, it’s now possible to write your own commands to do all kinds of tasks. Documentation for the plugin system is not yet written (and the previous one is outdated), but it should be straightforward to copy the supplied Lua plugin and change it to do something else. All you need is to know a little Lua (which is a simple scripting language) and explore Workbench internals using the GRT Shell (View -> Advanced -> GRT Shell).The sample Lua plugin is located in the modules folder. You can copy it to the custom plugins folder which is shown in the GRT Shell at startup and change things like the module name and add your own functions. I’ll write more about how to write such functions in a future post, like after the next WB is actually released.There are a few ways that plugins …
