Flyway’s Repair Command Explained Simply

The Repair command allows Flyway migrations to recommence on a database, following one or more validation errors. It modifies various details recorded in the schema history table, for applied migrations, to make them consistent with the data and metadata of the current set of Flyway migration files. This article explains what problems Repair can fix and how to run it safely, and a few alternative strategies. Read more

Data Container Revisions, Resets and Graduations

Redgate Test Data Manager allows developers to save each new version of a database as a data container revision. After making local development changes to the container, or running tests, they can instantly reset it to its starting revision. They can also load any previous revision and can even 'graduate' a revision to an image, providing a new baseline for ongoing team development. These techniques are especially effective when used in conjunction with Flyway, which automatically tracks the version of every copy of the database. Read more

Find the Version of a Flyway-managed Database

Maintaining a version of a database opens a lot of possibilities, especially if an automated process can easily grab the current version, at runtime. You might, for example, have a routine that is only appropriate after a particular version. It is also very handy to be able to associate entries in an event log or bug report with the database version. The article describes various ways to get the current Flyway schema version from Flyway, and how to get it using SQL, in SQL Server, MySQL, PostgreSQL and SQLite. Read more

Connecting Easily to Data Containers from Database Tools and IDEs

Data containers can be created, destroyed and reset remarkably quickly, making them very effective for test-driven database development. Each time we reset a data container, it will have the same host, but both the port and password will be different. This article demonstrates how we can use simple PowerShell automation to smooth the process of dealing with ephemeral connection details in our IDEs and command line tasks. Read more

Using TOML Configuration Files with Flyway

This article discusses Flyway's transition from CONF to TOML configuration files. It highlights the advantages of TOML, such as improved readability, flexibility in managing complex database configurations, and support for specifying multiple database environments. It also discusses a few of the differences to be aware of when switching existing Flyway projects to the new config system. Read more

Using Bash with Flyway

If you're using a Linux-based operating system, Bash is the obvious choice of scripting language for Flyway. This article demos the basics of dealing with credentials in team-based database development, when using 'traditional' flyway.conf files, and how to save and parse the JSON output of Flyway commands, for example to retrieve the current schema version. It provides a full automation example that will allow a team to maintain several copies of a database, one per development branch, from a Flyway project. Read more

Running Database Tasks and Tests on Clones in Redgate Test Data Manager

This article demonstrates how to adapt your current database development and testing regimes to use clones (data containers) in Redgate Test Data Manager. It demonstrates how to handle dynamic connection details and how to get from the containers the connection and database information that your development tasks and tests need to function correctly.

Simpler Enterprise Test Data Management using Database Instance Provisioning

Business applications are rarely self-contained, often depending on multiple interconnected databases, each playing a vital role in the functioning of the system. How can we create, refresh, and maintain test data for these complex database systems, and still support dedicated databases and test-driven development processes? This article explains how database instance provisioning helps meet this challenge. Read more
