In the latter case, you don't need to specify the domain of values the pivot operation needs to search.
What is unpivot in pivot?
Unpivot may be the opposite action of pivot but don't assume that former can reverse what latter has done. For instance, in the above example, you created a new table, CUST_MATRIX, using a pivot noperation on the table CUSTOMERS. Later you used unpivot on the table CUST_MATRIX but that didn't get back the details of the original table CUSTOMERS. Instead the crosstab report was displayed in a different way for you to load into a relational table. So unpivot is not for undoing what pivot did, a fact you should carefully consider before creating a pivoted table and then dropping the original one.
