I'm new in Java programming. I have an enum data type in my class:
public class Persons {
private String name;
private String family;
private Date birthDate;
public enum degree {Bsd, Msd, prof};
private degree degree;
...
}
In my MySQL database, I have a field for degree as: ENUM('Bsd','Mds','prof') and my hibernate mapping is like this:
<class name="Entity.Professor" table="tbl_professor">
<id column="ProfessorId" name="ProfessorId"/>
<property column="name" name="name"/>
<property column="family" name="family"/>
<property column="birthDate" name="birthDate"/>
<property column="degree" name="degree"/>
</class>
When I want to insert a new record in my table, I get this error:
Hibernate: insert into tbl_professor (name, family, birthDate, degree, ProfessorId) values (?, ?, ?, ?, ?)

Can anyone help me? I'm really confused with enum datatype.
