B-Tree Index As MySQL's default index type, a b-tree index is reasonably fast to insert new items into, and is fast at looking up individual items or even ranges. The index is stored as a branching tree, so looking up any one item is not an expensive operation. Each level of branching allows an order of magnitude more items. It's not always the best solution, but in some cases it may be the
If you plan to use the MySQL Workbench Migration Wizard to migrate databases from PostgreSQL to MySQL you first need to configure an ODBC driver to connect to your PostgreSQL server.
In this post I’ll cover how to set up and configure psqlODBC, the official ODBC driver for PostgreSQL.
Installing the psqlODBC Driver
The procedure is different for every platform so make sure to follow the instructions that correspond to the OS where you have MySQL Workbench installed. The driver needs to be installed in that machine, as explained in the MySQL Workbench documentation.
Windows
If you are running MySQL Workbench on Windows download the MSI package for psqlODBC. Go to its download page ( …

Money has proclaimed being a Database Administrataor as being the fifth best job in America. And they are telling the world exactly what we do, well as best they can in very few words.
What they do all day? It’s no understatement to say that corporate America is in the middle of an information explosion. Somebody has to keep track of it all. A database administrator (DBA) minds all the data in a company’s storehouse, keeps it safe and makes sure it’s easily accessible.
But what if you are not a DBA already?
How to get the job? A degree in computer science is recommended, followed by years of experience. Many employers require certification in the most widely used programs, including MySQL, Oracle and DB2. And since the technology is always changing, re-training is a constant.
So why would …

Last month Ubuntu 12.10 was released and we tried to install MySQL Workbench on it. So we went to http://www.mysql.com/downloads/workbench/ and downloaded the .deb file for the most recent Workbench version (5.2.44 as of this writing). We then opened the .deb file with the Ubuntu Software Center application and tried to install it. Unfortunately the following message appeared:
Dependency is not satisfiable: libctemplate0
The problem here is that the libctemplate package provided by Ubuntu 12.10 corresponds to a higher version (libctemplate2). Installing this version instead wouldn’t work since MySQL Workbench is linked against the older one. We’ll handle this dependency issue in future releases, but here’s a workaround:
