In this example, there are some rows with nulls in the sales and cogs columns. The rows are included in the output when using the INCLUDE NULLS clause.

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

Result:
