Issues with using Outer join in Data Template

Question

Hi all,
this is my data in two tables .
Table Ronny1
colA colB
1 u
2 v
3 x
Table Ronny2
colC colD
1 q
2 r
This is my data template
<dataTemplate name="MGF" dataSourceRef="Source1">
     <dataQuery>
          <sqlStatement name="Q1" dataSourceRef="Source1">
               <![CDATA[select C, D  from Ronny2]]>
          </sqlStatement>
          <sqlStatement name="Q2" dataSourceRef="Source2">
               <![CDATA[select A , B from lokesh1 where A = :C]]>
          </sqlStatement>
     </dataQuery>
     <dataStructure>
          <group name="G1" source="Q1">
               <group name="G2" source="Q2">
                    <element name="A" value="A"/>
                    <element name="B" value="B"/>
               </group>
          </group>
     </dataStructure>
</dataTemplate>
Now this would give me result as
A B
1 u
2 v
however my requirement is this
A B
1 u
2 v
3 x
that is, i want to display all the rows of table Ronny1 and matching rows from table Ronny2. I tried modifiying my second sql as
<![CDATA[select A , B from lokesh1 where A = :C (+)]]> ( using a outer join)
but this does give me correct data and comes back with the cartesion product.
Can anyone please answer this for me that how can we use the outer join in data templaes.
Thanks
Ronny

Answer 1

hey vetsrini,
sorry for the confusion here,
actually i want to display all the rows from table Ronny1 and i am also pulling in the matching rows from table Ronny2 and my data structure looks as ( pulling in column D from table Ronny2)
<dataStructure>
<group name="G1" source="Q1">
<group name="G2" source="Q2">
<element name="A" value="A"/>
<element name="B" value="B"/>
<element name="D" value="D"/>
</group>
</group>
</dataStructure>
and this is what i want the output to be
A B D
1 u q
2 v r
3 x
Hence the row where A <> C the data in the D column will be null, same as in the case of outer join.
any suggestions
Thx
Ronny
