That works, thanks! I'm creating the new column to append a [NEW] table to
the [OLD]. This is the only way I know how to do the following. But you may
know of a better way to do this.
I have two tables [OLD] & [NEW]. I would like to query any changes from the
old to the new. In the example below, SKU 12346 changed to 60, 12347 is not
in the [NEW] table, 12348 is added in the [NEW] table.
SKU OLD VALUE
12345 85
12346 70
12347 85
SKU NEW VALUE
12345 85
12346 60
12348 90
SKU OLD NEW CHANGED
12345 85 85
12346 70 60 Y
12347 85 Y
12348 90 Y
