Hi All,
In EJB 2.0 (CMP 2.0) if i set
<create-table>true</create-table>.
How the container creates table? Based on which
criteria it idenfies the columns of the table?
It is clear that all the CMP fields are treated
as columns? Are CMR fields are also treated as columns?
I have the following deployment
descriptor.
Unidirectional relation ship from Order to
OrderLine.
<relationships>
<ejb-relation>
<ejb-relation-name>Orderr-OrderLine</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>Orderr-has-OrderLine</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<role-source>
<ejb-name>Orderr</ejb-name>
</role-source>
<relationship-role-source>
<ejb-name>Orderr</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>orderLines</cmr-field-name>
<cmr-field-type>java.util.Collection</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>OrderLine-belongs-Orderr</ejb-relationship-role-name>
<multiplicity>Many</multiplicity>
<relationship-role-source>
<ejb-name>OrderLine</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
</ejb-relation>
</relationships>
The tables that are automatically created by the
container has following fields
For Order
Name
Null?
Type
----------------------------------------------------- --------
----------------
ORDERID
NOT NULL
VARCHAR2(255)
NAME
VARCHAR2(255)
ADDRESS
VARCHAR2(255)
This looks ok .
And For Order Line
Name
Null?
Type
----------------------------------------------------- --------
------------------
ORDERLINEID
NOT NULL
VARCHAR2(255)
ORDERID
NOT NULL
VARCHAR2(255)
PRODUCT
VARCHAR2(255)
ORDERR_ORDERLINES_ORDERID
VARCHAR2(255)
where i have not specified any CMR field for
OrderLine why is the 4th column created?
Can any body clear me what is that i am doing
wrong here?
Thanks in Advance
