Purpose

UNPIVOT is the reverse of the PIVOT operation. It provides a mechanism for transforming columns into rows.

The UNPIVOT functionality was introduced previously via the TD_UNPIVOT table operator. This feature introduces grammar to support the UNPIVOT operator in the FROM clause of the SELECT statement.

UNPIVOT invokes the TD_UNPIVOT table operator internally. You can still use TD_UNPIVOT independent of UNPIVOT.
