HI, Looking for suggestions on how to work with multiple inputs that cannot be joined directly. Here's the background.
The Report currently reads in two different Ecel files and uses 3 SQL commands to query an Oracle Database. I need to join the 5 data sources and am having issues with the 2 excel files. In one file I need to be able to derive a field based on another column in the file In order to create the join condition to the SQL commands. I'd equate this to a case statement in SQL, but how goes one do that using the 'add command' feature? What is the syntax?
Next I would need to join (left outer) the two excel files using two fields from file A (a1, a2) and 3 fields from file B (b1,b2,b3), where a1=b1 and b2 <= a2 <= b3 when rows from A exist in B. If row A does not exist in B then we still want it in the report and available to left outer join to the 3 oractab data sources.
runtime is also a concern.
Any Suggestions?
