The Unpivot component rotates a table by transforming columns into rows.
UNPIVOT is a relational Snowflake operator that accepts two columns (from a table), along with a list of columns, and generates a row for each column specified in the list. In a query, it's specified in the FROM clause after the table name.
This operator can be used to transform a wide table (e.g. jan_sales, feb_sales, mar_sales) into a narrower table (e.g. month, sales).
The Unpivot component is not a direct reverse of the Pivot component, since UNPIVOT cannot undo aggregations made by PIVOT.
