H2 SQLGrammarException: could not prepare statement

Question

I have a spring boot application with an h2 database that is addressed by a UserRepository. I am trying to use Spring security to authenticate using jdbc(Hibernate here)

@Entity
@Table(name="USER")

public class User {
    
    @Id
    @Column(name="USER_ID")
    private long id;
    
    @Column(name="USERNAME, nullable = false, unique = true")
    private String username;
    
    @Column(name="PASSWORD")
    private String password;
    
    /*setter/getter follows */
}

Repository:-

public interface UserRepository extends JpaRepository<User, Long>{
    User findByUsername(String username);
}

SQL:

CREATE TABLE USER(
    USER_ID BIGINT AUTO_INCREMENT PRIMARY KEY,
    USERNAME VARCHAR(128) NOT NULL UNIQUE,
    PASSWORD VARCHAR(256) NOT NULL
);

INSERT INTO USER (USERNAME,PASSWORD) VALUES('jdoe','foobar');

But when enter correct username and password, it is not accepting it.

Exception:

SQL Error: 42001, SQLState: 42001

Answer 1

Nice mistake:

@Column(name="USERNAME, nullable = false, unique = true")

->

@Column(name="USERNAME", nullable = false, unique = true)
