DRAG DROP
You are creating a sales data warehouse. When a product exists in the product dimension, you update the
product name. When a product does not exist, you insert a new record. In the current implementation, the
DimProduct table must be scanned twice, once for the insert and again for the update. As a result, inserts and
updates to the DimProduct table take longer than expected. You need to create a solution that uses a single
command to perform an update and an insert. How should you use a MERGE T-SQL statement to accomplish
this goal? (To answer, drag the appropriate answer choice from the list of options to the correct location or
locations in the answer area. You may need to drag the split bar between panes or scroll to view content.)
