Finding the Version of a Flyway-managed Database Using SQL

  • Article

Maintaining a version of a database opens a lot of possibilities, especially if an automated process can easily grab the current version, at runtime, using just SQL. 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. No more desultory quests, when dealing with support issues, or when bug fixing, to find which database version was running when the bug happened.

This article proposes a strategy where you create and test a rollback file, at the same time as the forward migration, and reuse it as a Flyway undo script.
