FlywayCross-RDBMS
Database Branching and Merging without the Tears
Armed with a schema comparison engine and an object-level directory of the source for every recent version of the database, you'll be able to remove a lot of the uncertainty around merging database changes back into development. Read moreHow to Automate Cross-Platform Database Development
In order to focus on their primary task of developing databases, the development team need to automate as many as possible of the routine tasks that are essential for database delivery, such as testing, scripting, version control, documentation, code review, reporting and so on. This article gives some advice on how to do it, faced with the added challenge of needing to use several different relational databases. Read morePiping, 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. Read moreComplex 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. Read moreA Simple Example of Flyway Development using GitHub Branching
This article demonstrates one way to do branch-based database development with Flyway, using GitHub to manage the branches and Flyway configuration files to allow Flyway to switch smoothly between databases, when we move between branches in GitHub. Read moreTesting Databases: What’s Required?
An overview of the challenges of database testing and test data management, reviewing the different types of database test that need to run during development work, what sort of test data they require, and how to manage all the required data sets, during development, in a way that allows rapid cycles of parallel testing. Read moreExecuting Optional Code in Flyway Callbacks
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 moreTransferring Database Documentation into SQL DDL Scripts
We all love having documentation in source code, if not writing it. We just want to ensure that it gets propagated and retained so you and your team members can read it if they need to. This article demonstrates a cross-RDBMS PowerShell task that will extract the comments from a primary JSON source of database documentation and add it to a set of SQL DDL source files. Read moreCross-RDBMS Code Quality Reports in Flyway
Before you commit your Flyway migration files, you may want to run some automated checks for style or 'code smells'. This article demonstrates how to run basic cross-RDBMS code quality checks using SQL Fluff. We analyze the results in PowerShell to produce reports and analytics on the number or types of issues found. Read moreRedgate Hub
