I found this comparing databases and genrating sql script using liquibase
and I was wondering if how I can do the same with Flyway. 1.- Generating sql script from the differences between tow databases.
Thanks!

Flyway is an open-source database migration tool. It strongly favors simplicity and convention over configuration. It is based around just 7 basic commands: Migrate, Clean, Info, Validate, Undo, Baseline and Repair.
While both tools are based on Martin Fowler's Evolutionary Database, there are many differences in what these tools offer. Here's where Liquibase and Flyway differ. The bottom line is that Liquibase is more powerful and flexible — covering more database change and deployment use cases than Flyway.
Liquibase offers a powerful open source database migration tool for Java apps. It brings structure and confidence to developers and DBAs that need to easily create and track database schema changes.
Flyway discovers SQL-based migrations from one or more directories referenced by the locations property. Unprefixed locations or locations with the classpath: prefix target the Java classpath.
How Flyway Works To keep track of which migrations we've already applied and when, it adds a special bookkeeping table to our schema. This metadata table also tracks migration checksums, and whether or not the migrations were successful. The framework performs the following steps to accommodate evolving database schemas:
Join the hundreds of thousands of delighted users. "Database migrations are something that Java developers struggle with, and Flyway provides a nice tool that anyone with basic knowledge of SQL can use. For that reason it has become the favourite migration tool in the Spring Boot team."
Flyway is based on concepts of linear database versioning. It means that the order of applied changes depends on migration scripts names. In fact, there is a whole naming convention for Flyway migration scripts, which you must follow if you want it to work as expected.
For those of you who use .NET and C#, there is a Flyway counterpart named Evolve so if you are interested you can check this one up. The link to its GitHub page will be at the end of the article. It started in 2006 and is an open-source tool for database migrations.
