What's wrong with database fields?

Question

MySQL

I'm trying to run the CRUD application taken from here , but with absolutely no success. The database has been created and is functioning, the problem here is different.

When I run the project - I get a server error 500 and this log

Hibernate: 
    select
        this_.id as id1_0_0_,
        this_.CODE as CODE2_0_0_,
        this_.ENTERING_DATE as ENTERING3_0_0_,
        this_.NAME as NAME4_0_0_,
        this_.nationality as national5_0_0_ 
    from
        student this_

It also tells me that

Request processing failed; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet

.

I don't understand what's wrong. I downloaded the code, and created the database myself, is there something wrong with it?
Moreover, I changed the URL, the password, because Spring finds this database and even tries to do something with it....

Answer 1

The error explicitly states that there is an unknown field:
Unknown column 'this_.nationality' in 'field list'
Check that the student table has a nationality field.
