Database not creating

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.

CodePudding user response:

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.
