Question

@Id
@Column(name = \"ID_ITEM_TO_REGISTER\")
@GeneratedValue         


        

Answer 1

As @jasonleakey suggested we can consider using naming-strategy as below.

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

this tells Hibernate to generate SQL's as exactly as specified in the @Table (name=" ") or @Column(name=" "). All well.

But keep in mind - while using PhysicalNamingStrategy without @Table, @Column annotations in the entity class, hibernate generates SQL using class name and variable names. Consider the below java class

Class Employee {
   private String firstName;
   private String lastName; 
}

then the generated sql would be,

select employee0_.firstName,employee0_lastName from Employee employee0_;

Unfortunately this is not a great choice as typically we would have defined the columns in DB as FIRST_NAME and LAST_NAME and table name as EMPLOYEE. Had you not used PhysicalNamingStrategy the SQL would have been

select employee0_.first_name,employee0_last_name from employee employee0_;

so it's really a choice between the below two options.

• Use PhysicalStrategy and explicitly define all tables names/column names in java code with @Table and @Column annotations.
  or
• Define lowercase table name in db and let hibernate automatically generate table names/column names for us.
