PIVOT syntax has been enhanced to support the aggregation of PIVOT results. The new syntax option to use for this aggregation is WITH.
- Improves the flexibility of the PIVOT function. You can use the enhanced syntax to aggregate resultant PIVOT columns, thereby avoiding writing complex SQL JOIN statements for aggregation.
- Performance is improved because you do not need to write JOIN statements to perform aggregation.
This feature is a Teradata extension to the ANSI SQL standard.
