SQL query against tables on MS SQL Server and Oracle using Oracle BI
392587Jun 24 2008 — edited Jun 25 2008Hi All
I have two databases Oracle and MS SQL Server. I want to write a query statement which will retrieve data from both databases and publish this data into one report. That is I want to join/merge data from tables in both database into one report with one SQL Statement something like:
Select o.F1,o.F2, m.F1,m.F2
from
table@oracleServer o,
table@microsoftSQLServer m
where o.F1=m.F1;
Can Oracle BI Publisher do this?
Basically I want to query simultaneously two heterogeneous data sources in one SQL statement. Is there such a tool? I don't want to build a warehouse by moving data from SQL Server into Oracle or vice-versa. I don't want to duplicate data. I want to be able to query data at its source via 1 SQL statement.
How would one go about doing such a thing?
Many Thanks
Kubilay.
