Example: Using UNPIVOT for a Unique Year Value - Analytics Database - Teradata Vantage

This example shows only one unique value of year, so the unpivot is straightforward.

SELECT *
FROM star1p UNPIVOT (Q1sales, Q2sales, Q3sales, Q1cogs, Q2cogs, Q3cogs) FOR
yr IN ((Q101Sales, Q201Sales, Q301Sales, Q101Cogs, Q201Cogs, Q301Cogs) AS
‘2001’) Tmp;

Result:

country  state  yr     Q1sales  Q2sales  Q3sales  Q1cogs  Q2cogs  Q3cogs
