[FIXED] Database not creating

Issue

I just started to use vaadin. I'm currently using the H2 database, but when I want to create the database "Upload" I get an error:

org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table upload (id varchar(255) not null, file_name varchar(255) not null, import_date bigint not null, month varchar(255) not null, year varchar(255) not null, primary key (id))" via JDBC Statement

I created like in the tutorial the Repository and the Service Class dedicated to the Upload Table.

Solution

MONTH and YEAR are reserved keywords in H2 and the SQL standard.

You have to rename the attributes or only the column with @Column annotation.
