Working with MySQL Workbench, I was always curious why you couldn’t run a script with a sourcing command, like source or \. command. It raises a 1064 error code, like the one shown in the illustration.

It turned out that there’s a pending feature request to add the ability to run a sourcing command like the following:

SOURCE c:\DATA\some_script.SQL

or,

\. c:\DATA\some_script.SQL

I added my business reason to the bug. Let’s hope the product managers add it quickly.

It’s always interesting when somebody asks why they got an error message, and especially sweet when you’re working on something related that lets you answer the question. They were using MySQL Workbench and wanted to know why they couldn’t open a SQL script file by clicking on the Scripting menu option.

As I explained to the individual who asked, you should always click the Edit SQL Script link in the SQL Development section of the MySQL Workbench home page to work on SQL scripts. The Scripting menu option supports Python and Lua plug-ins development and scripts.

They did the following initially, which led down the rabbit warren and left them stumped because they don’t know anything about Python or Lua. This is provided to those who choose to experiment with this advanced feature of MySQL Workbench.

As we know, MySQL workbench is excellent GUI tool for managing MySQL DB servers, creating ERDs (Data Modelling) and for sql development. But with this GUI tool, we are getting some command-line utilities too like mysqldiskusage, mysqlindexcheck, mysqlfailover, mysqldiff, mysqldbcompare etc., Here, I’m describing mysqldiskusage utility, which is not only displays mysql db usage but … Continue Reading …

MySQL Workbench provides several necessary tools in order to manage a MySQL environment. MySQL Workbench 5.2 is available for Windows, Mac and Linux platforms, it encapsulates three main functionalities:

1.    SQL Development: Allows connecting to existing databases and run SQL Queries, SQL scripts, edit data and manage database objects. This functionality replaces the ones previously provided by the Query Browser stand-alone application.

2.    Data Modeling: Helps to create and manage models, allows forward & reverse engineering and provides capability to compare and synchronize schemas

3.    Server Administration: Helps to configure a database server, to setup user accounts and browse status variables and server logs

Let’s have a look deeper in each of those features:

As an update to my prior post, I’ve added a form to the workbench plugin.  Now, the user can select a slow query log file and generate statistics from it.  The plugin provides information to answer the following questions:

Figure 1. Sample plugin form

• What type of queries run most often?
• What type of queries are the slowest?
• Which queries access the most rows?
• Which queries send the most data?

The plugin scans the slow query log, aggregates similar queries, and provides summary statistics for each group.  It’s very similar to the mysqldumpslow perl utility, which is included in the mysql bin folder. …

This is my first attempt at creating a plugin for MySQL Workbench.  As a first step, I’ve created a plugin that summarizes the slow query log if it’s output to the slow_log table, which is an option available in MySQL version 5.1 or newer.  It’s similar to the mysqldumpslow perl script, except that it doesn’t require perl, which should be more convenient on Windows.  In my next update, the plugin will provide the same summary statistics for the slow query log file on disk.

While the slow query log reports query time, lock time, rows sent and rows examined for each query; it’s often useful to group and aggregate similar queries for analysis.  For example, here’s a sample of the plugin output, which is sorted by count, after just a few clicks on a drupal6 site:

The plugin …

aka “How to use multiple MySQL Servers and Workbench in Snow Leopard without using Terminal… and live happily ever after”

The MySQL Community is a world of command-line aficionados. Many people, including myself, show their love to the simple-but-powerful interface of the mysql command-line client, but not everybody is keen to use a bash shell and give up its GUI, no matter how powerful the software is.

Until recently, GUI tools for MySQL were half baked solutions: in the end, there was always something that you had to do via the command line. Today, you can install, set up and use MySQL on your Mac with Snow Leopard without using Terminal, at all.

My Special Needs

Before digging into the details of the installation, let me describe what I need on my Mac. I use various versions of MySQL and I often need to run 2 or more instances at the same time. I constantly build, install and uninstall versions of …

Configure MySQL Server nodes for MySQL Cluster

The new version of MySQL Workbench (5.2.25) has just gone GA – see the Workbench BLOG for details.

So what’s the relevance to MySQL Cluster? If you have a Cluster that uses MySQL Servers to provide SQL access then you can now use MySQL Workbench to manage those nodes:

• Start & stop the mysqld processes
• Configure the per-mysqld configuration data held in my.cnf or my.ini

The reason that I describe the support as ‘partial’ is that these MySQL Servers are treated as independent entities (no concept of them being part of a Cluster) and there is currently no way to use it to configure or manage the other Cluster processes (data and management nodes). Having said that, what …

This week has been rough on my computers and I had to reinstall Vista on my main Windows system. But being a 'glass half full' guy, I took it as an opportunity to load the new alphas for both InfiniDB and MySQl Workbench.

I downloaded the InfiniDB software from http://infinidb.org/downloads/cat_view/40-binary-release/137-112-alpha-binary-releases and Workbench from http://dev.mysql.com/downloads/workbench/ respectively. In stalled them in that order and started the database and then Workbench.

I was expecting to have to fiddle with configuring one or the other to get them to work together. But I received a delightful surprise. Both worked out of the chute with no customization. Congratulations to the folks writing the install scripts at both companies!
