Subject [jira] Commented: (OPENJPA-1826) Can we have a new type for ignoring values?
Date Wed, 13 Oct 2010 20:27:34 GMT


Pinaki Poddar commented on OPENJPA-1826:

Added new action syntax 
	<promote-attr from="type" to="lob" if="text"/>

Will convert 
          <property name="value" column="COL_VALUE" type="text"/>
      <basic name="value">
        <column name="COL_VALUE"/>

> When I see the type="text" attribute in a Hibernate property element I would like to
be able to convert that to a <lob/> child element in OpenJPA.
> For example, I would like the following line in a Hibernate hbm.xml file:
> <property name="value" column="VALUE" type="text"/>
> to become the following orm.xml entry:
>       <basic name="value">
>         <column name="VALUE"/>
>         <lob/>
>       </basic>
> I can get <lob/> by using this in the actions for "property" in migration-actions.xml:
>     <promote-attr from="type" to="lob">
>       <map-value from="text"  to=""/>
>     </promote-attr>
> but that will only work if type's value is "text".  It would be great if we could introduce
a new type in migration-actions.xsd: "ignore-value".  We can already ignore elements and attributes,
but not values yet (unless they have particular values like the example above).  Then I could
do something like this:
>     <promote-attr from="type" to="lob">
>       <ignore-value/>
>     </promote-attr>
