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
For SQL Server 2019 onwards, Redgate Monitor can now show the actual execution plan, complete with runtime statistics, for expensive queries that were running over any period of investigation. This means you'll not only know how SQL Server executed your poorly performing query but also see accurate runtime data. Any big discrepancies between estimated and actual row counts will be revealed, and Redgate Monitor will highlight any warnings and offer recommendations. 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
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
