Maintaining a project like MySQL::Sandbox is sometimes tiring, but it has its advantages. One of them is that everything related to the server setup comes to my attention rather earlier than if I were an average DBA or developer.

I try to keep MySQL Sandbox up to date with every release of MySQL and (to a lesser extent) MariaDB [1]. For this reason, I am used to trying a new release with MySQL Sandbox, and … seeing it fail.

Of the latest changes in MySQL, probably the most disruptive was what happened in MySQL 5.7.6, where the mysql.user table lost the password column.

Yep. No ‘password’ column anymore. And just to make the setup procedure harder, the syntax of SET PASSWORD …

1. Interacting
2. Commanding
3. Debugging
4. Profiling
5. Windows OS

PowerShell + SQL Server is just cool! You will see folks talk about the ability to perform a task against multiple servers at a time, automate implementing a configuration or database change, or just obtaining a bit of consistency when doing certain processes. I tend to use it just because I can, and it is fun to see what I can do. There are a …

Student questions are always interesting! They get me to think and to write. The question this time is: “How do I write a Bash Shell script to process multiple MySQL script files?” This post builds the following model (courtesy of MySQL Workbench) by using a bash shell script and MySQL script files, but there’s a disclaimer on this post. It shows both insecure and secure approaches and you should avoid the insecure ones.

It seems a quick refresher on how to use arrays in bash shell may be helpful. While it’s essential in a Linux environment, it’s seems not everyone masters the bash shell.

Especially, since I checked my …
