Question

I have realized I am missing something obvious. Not sure what it is, Hoping somene an help me see what I am not seeing.

My company starts with mapping files and generates schema and java files.

I am trying to figure out how to map. I have a table with a column that can have only 1 on a limited number of strings:
‘DOES_NOT_EXIST’, ‘NEW,INITIATILIZE’, ‘RUNNING’, ‘TEARDOWN’

TABLE STATE_MACHINE
    ....
    STATE VARCHAR2(32)
.....


public enum StatEnum {
    DOES_NOT_EXIST, NEW,INITIATILIZE, RUNNING, TEARDOWN
}

what we want to do is something along the lines of

StateMachine machine = new StateMechine();
machine.state=StatEnum.NEW;
....
Persistance.save(machine)

Problems is I am receiving “Can’t commit transaction: Could not execute JDBC batch update: ORA-00932: inconsistent datatypes: expected BINARY got NUMBER”

I think the HBM mapping file should be something along the lines of

com.foo.StateEnum
12

Can some point me at some documentation that does what I am trying to do.

Thanks for helping me to learn…

Answer 1

I ended up creating a class that implements EnhancedUserType and ParameterizedType.

In the package that Implements the above classes I placed my enum class.

my Hibernate xml has

    <property name="state" column="state">
        <meta attribute="use-in-tostring">true</meta>
        <meta attribute="field-description">state types</meta>
        <type name="com.....h.core.domain.usertype.MyStrEnumUserType">
            <param name="enumClassname">com.......core.domain.usertype.StateTypeEnum</param>
        </type>
    </property>
