Why are my JPA-generated table columns in alphabetical order?

Misordering in JPA-Generated Tables

When generating tables using JPA, you may encounter situations where the column ordering differs from your expectations. Specifically, Hibernate will typically generate columns in alphabetical order.

Cause of Misordering

According to a Hibernate developer, the alphabetical ordering is implemented to ensure deterministic ordering across clusters. This behavior change occurred between Hibernate versions 3.2.0 GA and 3.2.1 GA.

Workaround

Unfortunately, there is no official fix for this issue. However, you can implement a workaround by naming your columns in a way that forces the desired ordering. For example, if you want the following column order:

id
organizationNumber
name

You could name your columns as follows:

a_id
b_organizationNumber
c_name

This naming convention will ensure that Hibernate generates the columns in the correct order.
