The goal of this article is to help Flyway developers search their migration files to pinpoint exactly where a specific database object, like a table, view, or procedure, was created or changed. It introduces a PowerShell script that scans files in version order and returns the relevant DDL statements with surrounding context. Read more
Learn how Flyway's state-based deployments help teams coordinate database changes and automate deployments, reducing risk, without disrupting existing development workflows. This article explains how they work, where they fit best, and when it makes sense to move to a migration-based approach. Read more
This article will cover the basics of the Flyway generate command and how it can auto-generate several types of Flyway migration scripts. This includes versioned migrations that, after testing, can be used to deploy changes, and baseline migration and undo scripts that are useful for a range of development tasks. Read more
This article explains how to compare databases and generate schema models using Flyway Enterprise CLI with PowerShell. It allows developers and DBAs to identify schema differences between environments and create schema models that capture the current state of a database, making it easier to track and review changes over time.

This article demonstrates using PowerShell-based tokenization to compare two SQL migration files. It ignores non-functional changes like comments or formatting and pinpoints the first meaningful change in SQL logic, providing detailed feedback on its location and nature. Read more
This article provides a scripted SQL tokenizer script that quickly verifies whether a Flyway validation error is a real cause for concern, due to retrospective metadata changes, or just the result of a developer valiantly adding formatting and documentation to improve the code. If the changes are purely cosmetic, we can safely run Flyway repair to resume normal migrations. Read more
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
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.

Database models have all sorts of useful applications during Flyway development to help us automate those repetitive development tasks that otherwise slow down delivery. This article shows how models can help us automate mundane tasks such as generating a build script for any version of a database or deleting the data from every table. Read more
A database model is a standard document that represents the logical design and structure of a database. If we save a model each time Flyway creates a new version of the database, then we can find out what's in each version, and get an overview of how that structure changed between any two versions. This has all sorts of uses in team-based database development work. Read more
