How to perform a range of useful database tasks automatically during Flyway migrations, using a DOS callback script. We provide a demo script that will collect all the necessary information from Flyway, run the task and then save any file with the appropriate name. You can use it to automate tasks such creating backups or DACPACs or generating a build script, each time Flyway creates a new database version. Read more
This article describes how we implemented lightweight database provisioning, using clones, within an automated Flyway release process . It allows users to self-serve personal copies of a complex multi-database system, in a way that is transparent, supports flexible Git branching and merging strategies and agile releases, but does not compromise data security nor add significant admin overhead.

Flyway connects to database using JDBC, but when we're automating Flyway with PowerShell, we can't use JDBC directly to get access to the metadata we need to add useful reports and other functionality to Flyway's build and migration processes. This article demonstrates how to get what we need using ODBC from our PowerShell scripts, via a DSN. Read more
This article explains the different ways to reverse or accelerate your way out of the problems caused by a failed database deployment, where a technique such as feature flags fits into your strategy, and how Flyway is designed to help you ensure both that you're fully prepared to take swift remedial measures, and that you minimize the need to use them.

This article explains the various ways of using placeholders to pass information and settings to any Flyway script, to gain bit of extra flexibility in a migration run., providing examples of conditional execution, running SQL expressions using environment variables and even one of using placeholders in a callback to send a warning notification to your phone, after a migration completes.

If you can convert a SQL file to HTML, then you can inspect your Flyway migration files in a browser. This is especially useful if your SQL is color-coded with the same conventions as it was in your IDE. It is even better still if your browser can allow you to scan through many files, moving from file to file with a single click. This article demonstrates how to do this with a few PowerShell scripts.

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
A database assertion test aims to check that data within a relational database conforms to specific business rules. This article demonstrates how to run these assertion tests automatically in Flyway, checking that the queries under test always produce the expected results. Read more
Consider a customer who needs to deploy sequence objects to multiple SQL Server production databases, but where the values generated for the surrogate key, in each database, must be unique. This article demonstrates one way that this can be accomplished with Flyway. Read more
How to run structured Arrange-Asset-Act-Teardown (AAAT) tests, each time Flyway successfully migrates a database, where you can annotate each test script to specify exactly how the test run should proceed, and then save all results and any errors to a simple ASCII report. Read more
