java - hibernate ConstraintViolationException after changing number of parameters

Question

I realized I needed 2 more columns for my table (date and hour, both of which are String type) and I added them in the database, model with constructors, getters and setters, hibernate file and everywhere in the repository, synchronized multiple times, but I get this error telling me 'hour' can't be null and I have no idea what it is talking about.

Anyone have any idea what it could be?

ERROR: Column 'hour' cannot be null

Answer 2

When modifying your schema your new columns will have value of Null for all records, seems like you have constraint of not null, in your java model you can specify that these columns can be null

    @Column(nullable=true)
