If you're using a Linux-based operating system, Bash is the obvious choice of scripting language for Flyway. This article demos the basics of dealing with credentials in team-based database development, when using 'traditional' flyway.conf files, and how to save and parse the JSON output of Flyway commands, for example to retrieve the current schema version. It provides a full automation example that will allow a team to maintain several copies of a database, one per development branch, from a Flyway project. Read more
This article demonstrates a PowerShell automation technique that will allow you to run any Flyway build or migration task on any number of projects and databases, hosted on a range of RDBMSs. It handles all connection and authentication details securely, makes it easier to automate database testing and can send detailed alerts when Flyway encounters an error. Read more
Once a scripted Flyway task is tested and bedded-in, it should rarely cause errors, so when one happens the team need to be notified immediately, especially if it is part of an automated deployment process. This article provides a PowerShell cmdlet that will execute any Flyway command, process and filter the Flyway output and send any errors to the chosen notification system. You can receive the Flyway error alerts on your mobile phone, if required! Read more
This article demonstrates two techniques for allowing Flyway to read extra configuration information from a secure location, possibly encrypted. The first technique pipes the contents of the config file to flyway via STDIN, and the second uses PowerShell splatting. This makes it much simpler to use Flyway to manage multiple development copies of a database using role-base security. Read more
This article explains why Flyway is fundamentally well-suited to the task of bringing control and automation to database development work and then the features of Flyway Teams edition that become necessary when a team of developers need to work concurrently on a database. Read more
Flyway's output is often overwhelmed with verbose messages, most of which we can ignore but some of which provide vital warnings about failed compilations, or useful details about what a migration or callback did. I'll show how to use some pipeline-aware PowerShell functions to filter out and save the bits we want and pass the results along in a form that is useful to the next process in the pipeline.

When you are building or migrating a database, it is nice to have a system that you can easily configure for various tasks, such as logging, loading or dumping data, or backing up of the database. This article demonstrates how we can use a Flyway placeholder as a simple on/off switch for each task, during Flyway migrations. Read more
A brief history of the DevOps movement and a discussion of the pivotal role of a tool like Flyway in the DevOps toolchain, when developing and delivering database changes. Read more
The FlywayTeamwork PowerShell framework is designed to help get you started quickly with scripting Flyway migrations for a range of database systems. It introduces a PowerShell task library to help with the scripting of repetitive chores and to generate some of the 'build artifacts' that are often required during team development work. This article explains the basics of the framework's design and provides a demo how to use Flyway to migrate a PostgreSQL database, while generating a high-level narrative of the changes made between versions.

Explaining some of the 'gotchas' that can trip up the unwary Flyway user, and how to avoid them. One or two of these you'll encounter quickly, such as the case-sensitivity of parameters and arguments. Others, such as potential problems with undo scripts or running scripted callbacks, only when you are tackling more complex development processes. Read more
Phil Factor offers a programmer's guide to Flyway's configuration settings, explaining the different categories of parameters, the role of each of parameter within each category, and how to exploit Flyway's multi-level configuration file system. Read more
Use Flyway to run your database migrations, each time automatically creating a SQL Change Automation release object to provide object-level scripts and a build script for the new version, along with change reports and code analysis reports. Read more
During the development cycle, the mechanics of reliable delivery must not be allowed to dominate the design work. With script callbacks in Flyway Teams, many of the development tasks required during a database migration can happen automatically, producing reports, build scripts, code reviews, or documentation. Read more
How to use Flyway configuration files to minimize typing during ad-hoc development from PowerShell or DOS; you just type in the Flyway commands you need and hit "go" and the config files take care of all the tiresome connection, authentication and project details. Read more
How Flyway Enterprise will help you ensure that databases and applications can grow and develop in step, and to implement a workflow for delivery of database changes that is resilient, repeatable, fast and visible. Read more
During development you need a fast, automated way to build multiple copies of a database on any development or test server, with each database at the right version. This article provides a PowerShell automation script for Flyway that will do the job. Read more
How to send Flyway logging and error output to JSON and consume it in PowerShell to produce ad-hoc database migrations reports, including any errors that occurred, the version of the database, runtimes for each migration script and more. Read more
