hi there,
i'm using TDK 2.1 and the added Torque version.
I am in need of Torque to let me generate classes from the project-schema.xml,
which only hold the the attributes i stated in the xml and absolutely do NOT
generate any save-Methods and Peers as well as no table.
This is because i have a SuperClass which holds all relevant items, and the
subclasses i want to generate are only holders for attributes which don't go
in the relational DB (they go in a XML-DB actually).
I tried to achieve my goal in different ways.
a) i tried to define an alias for a table since i thought this doesn't generate
the table. I was right for the table, but look at the field test i wanted to
be generated as a property of the class Product as well as their getter/setter-Methods.
It didn't generate it at all.
<table name="Product" javaName="Product" alias="KnowledgeObject"
baseClass="iknow.share.om.KnowledgeObject">
<!-- Unique identifier -->
<column name="id" primaryKey="true" required="true" type="integer"/>
<!-- Fields for XML -->
<column name="test" size="255" type="VARCHAR"/>
</table>
b) second try, i looked into the database.dtd. There i found skipSql. Now i really
don't know what this does(i didn't find a doku of it), but it sounded really like
something i maybe wanted. So i tried the following, which caused the table not
to be created (good!) but at the generation of the OM-Classes ant stopped
with a generator.parse exception (it is thrown only when i use skipSql=true):
<table name="Product" javaName="Product" skipSql="true"
baseClass="iknow.share.om.KnowledgeObject">
<!-- Unique identifier -->
<column name="id" primaryKey="true" required="true" type="integer"/>
<!-- Fields for XML -->
<column name="test" size="255" type="VARCHAR"/>
</table>
Now, i was wondering if someone could tell me if skipSql is the key to the solution
or there is something far more easy to accomplish what i want.
If skipSql is the right choice, maybe someone knows why the following exception is
thrown?
Please help me! ^^
