Piping, Filtering and Using Flyway Output in PowerShell

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.

Recording What’s Changed when Running Oracle Migrations with Flyway

This article uses Flyway and a PowerShell framework to generate a simple JSON model for each new version of an Oracle database, and then compares models to get a high-level 'narrative' of which tables, views or procedures were changed by each Flyway migration. Read more

Complex Production Database Deployments and Flyway

This article explains how, by use of schemas and stub interfaces, we can use Flyway to manage the main development work smoothly alongside any changes or additions required to maintain production-only code. It also demonstrates how this mechanism enables Flyway to manage a 'mock' or 'dummy' variant of a production schema, in development, so that the team can still develop and test code that, when deployed, will access production-only features.

Undoing Actions on Groups of Database Tables

During development you'll occasionally need an undo script that drops a group of tables, or you might need to truncate a group of tables and then insert fresh data in order to run some tests. Unless you perform the required actions in the correct dependency order, you'll be tripped up by foreign key constraint violations. This article provides a SQL function that returns the list of tables in the correct dependency order. Read more

Getting Started with Flyway Migrations on Oracle

A quick demonstration of using Flyway with Oracle, for those of a nervous disposition. We'll use Flyway to run some migrations on an Oracle Autonomous Database, building the initial version of the database then filling it with development data. Read more
