Example: Using UNPIVOT with the EXCLUDE NULLS Clause - Analytics Database - Teradata Vantage

In this example, there are no rows with nulls in either the sales or cogs columns, and the rows are excluded in the output when using EXCLUDE NULLS clause. This is the default option.

SELECT *
FROM star1p UNPIVOT EXCLUDE NULLS (sales, cogs)  FOR  yr_qtr IN
((Q101Sales, Q101Cogs) AS 'Q101', (Q201Sales, Q201Cogs) AS 'Q201', (Q301Sales, Q301Cogs) AS 'Q301') Tmp;

Result:

country  state     yr_qtr        sales         cogs
-------  ------   --------   ------------    -------
Canada      ON     Q201           10            0
Canada      ON     Q301           10            0
USA         NY     Q101           45           25
