Hi.
I have some models to be persisted in Teneo and there is some properties, which data length exceeds the default length of the database field (type varchar I guess because that properties are Strigs). Therefore, I can't persist properly my models...
I would like to know how to get that field larger in my MySQL DB (instead the default length, a varchar of 8192) after the initialization...
I have seen annotations like the following:
<eClassifiers xsi:type="ecore:EClass" name="xxxx" abstract="true">
<eAnnotations source="teneo.jpa">
<details key="value" value="@Column(length=8192)"/>
</eAnnotations>
but I don't know exactly how to apply them (maybe using some kind of generator, but the menu option of the Eclipse IDE, which is called 'Teneo' liekely to generate de hbm files, doesn't work fine (probably due to a missing artifacts).
So... please, what's the simplest way to solve this issue? Is there any way of giving parameters about the metamodel to the Teneo initialization?
Any other suggestion?
Thank you very much in advance.
Best regards.
Carlos.

Hi Carlos,
You can add annotations in 2 ways:
- in the xsd or the ecore file
- in a separate xml file
http://wiki.eclipse.org/Teneo/Hibernate/ModelRelational/Annotations_Format
see for other wiki articles here:
