Data from different databases in the same report.

Question

Hi Everyone,
I am trying to build a reconciliation report in which I need to show the data from the source and target, side by side.
Source and target are both different databases, although being oracle only
Whenever a new data model is created, it gets attached to a data source and in the report we need to choose a specific data model.
Can we have data from different databases in the same report ?

Answer 1

Yes, it is possible.
One way Is to use dataTemplates. There you can make queries from any number of different databases (The max I have done is 5).
It looks something like that:
<dataTemplate name="NameOfTemplate">
<dataQuery>
     <sqlStatement name="Q1" dataSourceRef="Connection1">
          <![CDATA[     select * from table1]]>
     </sqlStatement>
     <sqlStatement name="Q2" dataSourceRef="Connection2">
          <![CDATA[     select * from table2]]>
     </sqlStatement>
  </dataQuery>
  <dataStructure>
     <group name="RESULT1" source="Q1">
          <element name="P_FIRST_NAME" value="P_FIRST_NAME"/>
     </group>
     <group name="RESULT2" source="Q2">
          <element name="P_DATE" value="P_DATE"/>     
     </group>
  </dataStructure>
</dataTemplate>dataStructure is very important when you get data from different places, if you don't define those elements, then only the result from Q1 is shown.
The second possible way is to make as two different data models, each containing their own query and then set Main Data Set as concatenated SQL Data Source.
Best of luck,
