Im a little new to using lookup transforms. Been reading a bit, but using two columns is throwing me off.
Have a dataflow with the source having a column I want to use to lookup in a table in another DB. The match could be in one of two columns in that table.
If a match is found, I need a different value from the lookup table added to the source flow that is going into the destination.
How can I match on one of two columns in the lookup table, and use a totally different column added to the final input going into the destination ?
In the Lookup configuration, I can set the lookup operation to replacing the value in the source, but I want EITHER value match from the two columns from the lookup table to go into the value that will go into the destination.
With TSQL - I would use a case statement and compare the source column to BOTH of the lookup table columns.
