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.

Rollbacks, Undos and Undonts

  • Article

Rollback scripts are designed to allow us to recover safely from a failed deployment that leaves the database in an indeterminate state. They must check exactly what needs to be reverted before doing so. If you work with an RDBMS that cannot support transaction DDL rollback they are vital. 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.

  • Article

A generic way of exporting, deleting and loading data, for database development work. It uses Flyway Teams, a PowerShell framework, JSON files for storage and a table manifest to define the correct order of dependency for each task. It should help a team maintain datasets between database versions, as well as to switch between the datasets required to support different types of testing.

Question of the Day

Restoring On Top II

I have a database, DNRTest, that has a number of tables and other objects in it. The other day, I was trying to mock up a test and ran this code on the same server:

-- run yesterday
CREATE DATABASE DNRTest2
GO
USE DNRTest2
GO
CREATE TABLE NewTable (id INT)
GO
Today, I realize that I need a copy of DNRTest for another mockup, and I run this:
-- run today
USE Master
BACKUP DATABASE DNRTest TO DISK = 'dnrtest.bak'
GO
RESTORE DATABASE DNRTest2 FROM DISK = 'dnrtest.bak' WITH REPLACE
What happens?
