Example: Using an IN List with Multiple Column Lists and Unspecified Aliases - Advanced SQL Engine - Teradata Database

In this example, the aliases that the IN list uses were not specified. Instead, the values of the yr_qtr column were built by adding the column names with an underscore symbol.

SELECT *
FROM star1p UNPIVOT ((sales, cogs)  FOR  yr_qtr IN
((Q101Sales, Q101Cogs),(Q201Sales, Q201Cogs), (Q301Sales, Q301Cogs)) Tmp;

country    state        yr_qtr                        sales         cogs
