PerconaLive Amsterdam 2016 - Talks and shows

With Oracle Open World behind us, we are now getting ready for the next big event, i.e. the European edition of PerconaLive. I am going to be a presenter three times:

  • MySQL operations in Docker is a three-hour tutorial, and it will be an expansion of the talk by the same title presented at OOW. Attendees who want to play along can do it, by coming prepared with Docker 1.11 or later and the following images already pulled (images with [+] are mandatory, while [-] are optional):

Fast data import trick

A few weeks ago my friend Frank de Jonge told me he managed to improve an import into a MySQL server down from more than 10 hours to 16 minutes. According to him it had to do with several field types (too long fields to really small data), the amount of indexes, and constraints on the tables. We were talking about 1 million records here. He wondered if it was possible to make it even faster.

The basics

Turns out there are many ways of importing data into a database, it all depends where are you getting the data from and where you want to put it. Let me give you a bit more context: you may want to get data from a legacy application that exports into CSV to your database server or even data from different servers.

If you are pulling data from a MySQL table into another MySQL table (lets assume they are into different servers) you might as well use …

Creating a Test Lab Using VirtualBox / NAT networking

My job is almost completely reliant upon my ability to perform work in lab of virtual machines. Almost every action plan I write is tested locally. When I need to troubleshoot an issue for a client one of the most common first steps I’ll perform is attempting to recreate the issue in a virtual environment so I can work on it there without the risk of impacting client data.

I believe that having a place to test and grow your skills is an absolute necessity for anyone working in the IT field today regardless of your specialization, even if you’re an IT generalist. But every now and then I hear about individuals who have issues with their virtual machines or with the virtual environment provided by their employer, so I figured this was a good time to share my method of creating a virtual lab. More specifically, one that allows you to do virtual work on a commodity laptop, one that won’t break down if you lose connectivity, one that …

For the brave: compiling Workbench 6.3 using Visual Studio 2013 on Windows

Compiling MySQL Workbench yourself is quite a common task for Linux users, even though the application is available precompiled for certain platforms ready from our download page and available in our yum and apt repositories. In this blog post we show you how to compile it on Windows.


Doing a build on Windows is a totally different matter and most users never need to do that. It’s mostly intersting for those wanting own functionality or just being curious. But you should be an experienced Visual Studio user. It’s a complicated task and not a good start for a beginner. The key problem when building on Windows is that we cannot ship any 3rd party library we used. Instead you have to collect them all yourself. In order to ease that task we created the list below. Each library comes with a version number which usually specifies the minimum version to be used. Most of the time it’s not mandatory to use the exact …

How-To: Guide to Database Migration from MS Access using MySQL Workbench

Edit: added sample table output in MySQL

MySQL Workbench 6.2 introduces support for MS Access migration. This tutorial should help you get your Access tables, indexes, relationships and data in MySQL.


Because MS Access ODBC drivers are only available for Windows, migrating from it is also only possible from Windows. As for the destination MySQL server, you can have it in the same local machine or elsewhere in your network.

MS Access stores relationship/foreign key information in an internal table called MSysRelationships. That table is protected against read access even to the Admin user, so if you try to migrate without opening up access to it, you will get an error like this:

[42000] [Microsoft][ODBC Microsoft Access Driver] Record(s) cannot be read; no read permission on 'msysobjects'. (-1907) (SQLExecDirectW)

The steps to grant read access to …

New MySQL Workbench video

The MySQL Workbench team just uploaded a new video to the MySQL channel at Youtube. This video is meant for beginners and describes the process of creating and troubleshooting connections in MySQL Workbench.

MySQL Workbench: Vertical Query Output

MySQL Workbench have one nice feature which is probably a stranger for some of us. The name of this feature is vertical query output, it help in situations where the standard Workbench output will not be very useful. This functionality is very easy to use and in this post I’ll try to visualize some of it’s benefits.

First we need to know how to use it, so we’ve provided you two options to execute the query with vertical output. One of them is the menu bar where you can find item named Execute vertically, you’ll also find hint about the shortcut for that option it’s CTRL+ALT+RETURN.

After you know how to get the vertical query output, I’ll show you some screen shots to compare it with command line output.

Let’s take the command that suits best to this type of output, it’s SHOW ENGINE INNODB STATUS. Normally to understand the output, you probably copy it to some notepad app, and …

MySQL Workbench 6.0: Help is on the way…

Do you know this scenario: you are writing down  a stored procedure but you can’t for the life of you remember the exact syntax of that CASE statement? Has it to end with CASE or not? Can I use more than one WHEN part and how should that be written? Usually you end up opening a web page and read through the excellent MySQL online docs. However, this might cost too much time if you quickly need different statements and other detail info. Here’s where MySQL Workbench’s context help jumps in.

The server can help

It’s probably only known to the die-hard terminal operators who write most of their SQL queries in a MySQL console window: the MySQL server already has a stripped down set of help topics produced by the Docs team. That means you can always get at least the syntax but often far more information for a particular syntax element when you work with a server. When you …

Video Tutorial: Setup a Restricted SQL Server Account for Migrations with MySQL Workbench

Some users have asked us what is the minimum set of privileges that your Microsoft SQL Server user needs to successfully migrate databases from SQL Server using the MySQL Workbench Migration Wizard. Even though we don’t execute any query that alters anything in your source RDBMS servers, it’s never a bad idea to add an extra security barrier around it.

In short, you need the VIEW ANY DEFINITION permission for the server and the CONNECT and SELECT permissions for the database(s) you want to migrate. But to make this easier for you, we have created a video tutorial showing how to create a user with these permissions using the Microsoft SQL Server Management Studio.

How-To: Database Migration from Sybase Adaptive Server Enterprise using MySQL Workbench

In this tutorial I’m going to show you how to migrate your Sybase Adaptive Server Enterprise databases to MySQL.

As usual, we’ll start with a couple assumptions:

  • You have MySQL Workbench 6.0 installed.
  • You have a running Sybase Adaptive Server Enterprise database somewhere in your network. I’ll be using the pubs3 sample database that Sybase distributes with Adaptive Server Enterprise 15.
  • You have installed the Sybase Adaptive Server Enterprise ODBC drivers in the same PC where MySQL Workbench is running. The ODBC drivers are distributed with the Sybase Adaptive Server Enterprise SDK and included in the Adaptive Server Enterprise Developer Edition.
  • A running MySQL Server instance …
