DB-Adapter 10g: Filtering Detail-Rows in Master-Detail-Relationship

Question

Hi,
I'm having a Master-Detail-Table e.g. Departments and Employees. Those are mapped with 1:N FK-Relationship. Using the Oracle SOA-Suite 10.1.3.5 DB-Adapter I'd like to setup a filter returning all Departments and all (e.g.) female Employees.
For the example see: http://docs.oracle.com/cd/E11036_01/integrate.1013/b28994.pdf (chapter 4.3.9). Unfortunately, this doesn't work. If definining a where-clause empCollection.gender='female' I get the following behavior:
- If a dept has no female emp, this department is not shown at all (however I want it to be empty)
- If there is at least one female emp, the department and all employees are shown.
Any idea on how to solve this problem would be highly appreciated!
Regards,
Johannes

Answer 1

I gave it a try, 2 problems:
1) the outer-join seems to be wrong. it provides me only departments that have at least one female employee. If I change that outer-join to:
select DEP.id,DEP.name, EMP.id,EMP.GENDER
from EMP, DEP
where EMP.DEP_ID(+)=DEP.id
and emp.gender(+)='female'
it gives me what I want from sqldeveloper:
select * from emp;
ID NAME
1 empty
2 mixed
3 male
4 female
select * from dep;
ID DEP_ID GENDER
1 2 male
2 2 female
3 2 male
4 3 male
5 3 male
6 4 female
7 4 female
8 4 female
select DEP.id,DEP.name, EMP.id,EMP.GENDER
from EMP, DEP
where EMP.DEP_ID(+)=DEP.id
and EMP.GENDER(+)='female'
ID NAME ID GENDER
1 empty
2 mixed 2 female
3 male
4 female 6 female
4 female 7 female
4 female 8 female
2) However that doesn't solve my problem with the BPEL-Adapter. There I still get the folowing result:
<DepCollection xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/top/test4" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Dep>
<id>2</id>
<name>mixed</name>
<empCollection>
<Emp>
<id>1</id>
<gender>male</gender>
</Emp>
<Emp>
<id>2</id>
<gender>female</gender>
</Emp>
<Emp>
<id>3</id>
<gender>male</gender>
</Emp>
</empCollection>
</Dep>
<Dep>
<id>4</id>
<name>female</name>
<empCollection>
<Emp>
<id>6</id>
<gender>female</gender>
</Emp>
<Emp>
<id>7</id>
<gender>female</gender>
</Emp>
<Emp>
<id>8</id>
<gender>female</gender>
</Emp>
</empCollection>
</Dep>
<Dep>
<id>3</id>
<name>male</name>
<empCollection>
<Emp>
<id>4</id>
<gender>male</gender>
</Emp>
<Emp>
<id>5</id>
<gender>male</gender>
</Emp>
</empCollection>
</Dep>
<Dep>
<id>1</id>
<name>empty</name>
<empCollection />
</Dep>
</DepCollection>
This is how I used the wizard:

Any futher ideas?
