So, after installing Workbench 6.0.7 on my pc, and playing around with the MySQL Utilities that are included, I thought I’d do similar to what others have done (Thanks Tony D.) and share my experience on how I’ve used them. If you haven’t installed Workbench before, you might want to check your platform first: http://www.mysql.com/support/supportedplatforms/workbench.html.

So, even if you’re not using any of the recent versions and editions of Workbench (Utilities comes with all of them, Tools menu -> “Start Shell for MySQL Utilities“) you can just download the standalone scripts on a Linux machine. Flexibility being the name of the game again. …

Connector/Python v1.1.3 is available for testing since last week. It is a “beta” release, so it would be great if we even get more feedback. Check out the Change History if you want to keep up with what is being added and changed.

Notable changes for v1.1.3 include a fix for encoding using \x5c or backslashes in multi-byte characters. We also made the code more PEP-8 compliant, which we think is quiet important.

Problem

You have a query executed by MySQL Connector/Python and would like to show column information nicely on the console.

Solution

Every cursor object has a description property. This can be used to show information about the columns in a result set.

columns = []
maxnamesize = 0
for coldesc in cur.description:
    coldesc = list(coldesc)
    coldesc[2:6] = []
    columns.append(coldesc)
    namesize = len(coldesc[0])
    if namesize > maxnamesize:
        maxnamesize = namesize

fmt = "{{nr:3}} {{name:{0}}} {{type:12}} {{null}}".format(
    maxnamesize+1)
colnr = 1
for column in columns:
    (colname, fieldtype, nullok, colflags) = column
    print(fmt.format(
        nr=colnr,
        name=colname,
        null='NOT …

“The most valuable thing I’ve learned in this role is that judicious use of a little bit of knowledge can go a long way. I’ve seen colleagues and other companies get caught up in the “Big Data” craze by spend hundreds of thousands of pounds sterling on a Hadoop cluster that sees a few megabytes [...]

MySQL Fabric was officially introduced during Tomas his keynote at MySQL Connect 2013. MySQL Fabric will help you managing lots of MySQL server supporting both high-availability and sharding. Just like Connector/J, MySQL Connector/Python v1.1.1 Alpha has support for MySQL Fabric on MySQL Labs. Note that the MySQL Fabric as well as support for it in Connector/Python is Alpha.

When you download MySQL Connector/Python from MySQL Labs, you will also see a ZIP archive containing the MySQL Utilities documentation …

Applications should be written taking into account that errors will eventually happen and, in particular, database application developers usually consider this while writing their applications.

Although the concepts required to write such applications are commonly taught in database courses and to some extent are widely spread, building a reliable and fault-tolerant database application is still not an easy task and hides some pitfalls that we intend to highlight in this post with a set of suggestions or tips.

In what follows, we consider that the execution flow in a database application is characterized by two distinct phases: connection and business logic. In the connection phase, the application connects to a database, sets up the environment and passes the control to the business logic phases. In this phase, it gets inputs from a source, which may be an operator, another application or a component within the same …

In this post, we are going to show how to develop fault-tolerant applications using MySQL Fabric, or simply Fabric, which is an approach to building high availability sharding solutions for MySQL and that has recently become available for download as a labs release (http://labs.mysql.com/). We are going to focus on Fabric's high availability aspects but to find out more on sharding readers may check out the following blog post:

Servers managed by Fabric are registered in a MySQL Server instance, called backing store, and are …
