Database Migrations for Beginners | Flyway Tutorial

Hello! Let's take a look at how database migrations work and why they are needed. This concept is the exact same across any language/framework, however I will be doing a demo using Javas Flyway. I hope you enjoy it!

It’s insane how you speak so fast but maintain a clear explanation, you are really good at explaining

Thank you for being straight on point and showing a problem straight forward. I didn't get why my student project asks me to create project with sql migrations from the start on, now I get it!

Great tutorial! I liked the hands-on approach of actually showing the workflow in the IDE.

Thanks for this introduction. I'm used to working with DACPACs and MSSQL. They each have their own method and process of migrating and updating but have the same goals. I just need to learn how Flyway carries them out.

My last project had database migration written in-house from scratch, nice to know I don't have to give up on it

[chuckinator]

Nice tutorial. I just want to note the worst naming in all of computer science: “database schema”. This video is about data schemas, ie the format of your data, ie what fields there are in the table and their types.

Then there’s “database schema” which is completely unrelated. This is a namespace your database uses for tables. For example, you might have two tables postgres.prod.users and postgres.dev.users. The tables have the same name, but are in different schemas (ie namespaces) dev and prod.

This was very confusing to me at one point, so hopefully it helps someone out.

I rather using Django for migrations, obviusly while having python knowledge in the matter. Excellente vid btw

[ТимурЯлымов-фо]

Great tutorial! I have one question: Is it possible to automatically run migration script on the application startup? I want to do it automatically on every new-version deployment of my application
