Celestial Bodies Database - Primary Keys Issues

Backend Development
1

I am almost done with my project. The only thing preventing the test from passing is this requirement “Each primary key column should follow the naming convention table_name_id. For example, the moon table should have a primary key column named `moon_id”. I used the name convention throughout the project and don’t know how I went wrong. I have provided the SQL dump.

could this column name be the issue? it should be blackhole_id

I managed to resolve it but it was column naming issue from my part
