Hibernate, one UserType with different number of columns

Question

I have class

class DateOptTimeType implements org.hibernate.usertype.UserType

that works with two columns

@org.hibernate.annotations.Type(type = "com.mmyPack.DateOptTimeType")
@org.hibernate.annotations.Columns(columns = {
                 @javax.persistence.Column(name = "DATE1"),
                 @javax.persistence.Column(name = "FLAG")
                                   }) protected DateOptTime dateOfDeath;

Can i do, that class will work with 1 column too (with 1 column and with two columns), like

                    @javax.persistence.Column(name = "DATE1"),
                    protected DateOptTime dateOfDeath;

Answer 1

You need 2 UserTypes because the UserType returns the number of needed columns in getSqlTypes()
