Example: Using an IN List that Contains Multiple Columns with a Compatible Data Type - Analytics Database - Teradata Vantage

In this example, the Q101Sales column contains an INTEGER data type, and Q201Sales is a BYTEINT data type. Both the INTEGER and BYTEINT data types are compatible with each other.

SELECT * FROM star1p UNPIVOT (measure_value  FOR  yr_qtr_measure IN
(Q101Sales, Q201Sales)) Tmp;

Result:

country     state  yr_qtr_measure  measure_value
