Taming Database Documentation with Flyway and MySQL

Database object documentation is essential for explaining to busy developers, and the wider business, the purpose of each object and how to use it. The solution presented in this article consists of a SQL script to allow developers to add comments to MySQL database objects, without affecting the database version, and a simple way to generate a documentation report, in JSON. The SQL script will execute automatically as a callback, during any Flyway Teams migration run, and the report will allow the team to spot any gaps quickly. Read more

Cross-RDBMS Version Checks in Flyway

How does one check that a database is definitively at the version that Flyway says it is? Or that a test teardown procedure leaves no trace in the database? Or verify that an undo script returns a database's metadata to that state it should be in for the version to which you're rolling back? This article shows how to do high-level version checks, by comparing JSON models. Read more

It updates a database by running a series of versioned migration scripts, in order, and keeps track of all the changes in a special "schema history" table. It sounds simple, but it is easy to derail this team discipline if you don't find the right answers to the following questions… Read more
