We have two flat files and need to join these two flat files to generate the data.
Listed below the tables and their corresponding columns.
SITES - Siteid, Sitename
TRANSPORT - Sourceid, Destinationid, Quantity , Weight

So the requirement is if we join sites.siteid with transport.sourceid, then we get the Source Name
Then if we join sites.siteid with transport.destinationid , then we get the Destination Name.

Please help me in creating the same in Omniscope file by using the 'Merge/Join' Operation.

If we had considering these flat files as tables and written the join condition, the query looks as mentioned below.
SELECT so.siteid sourceid
, so.sitename sourcename
, de.siteid descid
, de.sitename descname, t.qty, t.weight
FROM temp_sites so
, temp_transport t
, temp_sites de
WHERE de.siteid = t.descid
AND so.siteid = t.sourceid

So now we need to create an iok file based on this query.

Please let me know how to create this step.]]>
