Versioning system for database

阅读更多关于 Versioning system for database

问题 We have a java application which uses spring boot and hibernate. There are many changes on entities and fields. That's why, I want to follow changes and rollback mechanism. So that, I need a version control system over database. I checked flyway and liquibase, but I think those don't solve my problem. Because my table creations and updates are handled by hibernate.

How can I merge multiple files into a single flyway migration?

阅读更多关于 How can I merge multiple files into a single flyway migration?

问题 I have two sql file /migrations v1.0.0__geo-areas-tables.sql v1.0.0__geo-areas-data.sql These files are the same version of the migration. How can I apply them within the limits of migration 1.0.0? P.s. I do not want to use additional scripts combine these files into one. 回答1: The rule is simple: one version = one script. In your case you probably want to name them v1.0.0.0__geo-areas-tables.sql and v1.0.0.1__geo-areas-data.sql as that is the order you want to guarantee anyway. 来源： https:/
