             Summary: Allow PhysicalNamingStrategy implementations to detect when a name is implicit or explicit
                 Key: HIBERNATE-160
                 URL: https://issues.jboss.org/browse/HIBERNATE-160
             Project: Hibernate Integration
          Issue Type: Feature Request
            Reporter: Phillip Webb
            Assignee: Steve Ebersole
            Priority: Optional


It's possible for column names to be explicitly defined, for example:

{code:java}
@Column(name = "firstName")
private String firstName;
{code}

Or deduced implicitly from the name of the field:

{code:java}
@Column
private String firstName;
{code}

Both of these forms result in a call to {{PhysicalNamingStrategy}} with an {{Identifier}} but it's not possible to tell if the identified is explicitly named or deduced (the relevant code is [here|https://github.com/hibernate/hibernate-orm/blob/47382f69cc282a3df1bc373300eeeeee5237b81f/hibernate-core/src/main/java/org/hibernate/cfg/Ejb3Column.java#L304] and [here|https://github.com/hibernate/hibernate-orm/blob/47382f69cc282a3df1bc373300eeeeee5237b81f/hibernate-core/src/main/java/org/hibernate/cfg/Ejb3Column.java#L311]).

It would be nice if the {{Identifier}} could include an additional field that tells us where it came from. This would allow generic naming strategies to be developed that back-off when a {{name}} attribute is defined by the user.

For more background on users that are asking for this see [this Spring Boot issue|https://github.com/spring-projects/spring-boot/issues/2129].
