Thomas Dudziak commented on OJB-16:
-----------------------------------

OJB uses the procedure whose name is given in the name attribute of the procedure element in the repository.xml.
See here for the syntax of the already supported procedures:

>          Key: OJB-16
>          URL: http://issues.apache.org/jira/browse/OJB-16
>      Project: OJB
>         Type: New Feature
>   Components: PB-API
>     Versions: 1.0.x CVS
>     Reporter: Vadim Gritsenko
>     Assignee: Thomas Dudziak
>  Attachments: SelectByPKProcedureDescriptor.java, db-ojb-selectbypk.diff, xdoclet.diff
>
> This patch adds support for retrieving objects by primary keys through call to stored procedure instead of using select statement.
> To activate the feature, add xdoclet tag to the class:
> /**
>  * @ojb.class table="MYBEAN"
>  * @ojb.selectbypk-procedure name="FIND_MYBEAN_BYID"
>  */
> public class MyBean {
>     /**
>      * @ojb.field primarykey="true"
>      */
>     Integer id;
> }
> And then, create stored procedure:
> CREATE OR REPLACE PACKAGE TYPES AS
>   TYPE CURSORTYPE IS REF CURSOR;
> END TYPES;
> /
> CREATE OR REPLACE FUNCTION FIND_MYBEAN_BYID (ANID IN MYBEAN.ID%TYPE)
> RETURN TYPES.CURSORTYPE AS
> RESULT TYPES.CURSORTYPE;
> BEGIN
>   OPEN RESULT FOR SELECT * FROM MYBEAN WHERE ID = ANID;
>   RETURN RESULT;
> END;
> /
> Patch is made against OJB_1_0_RELEASE branch.
