The pivot_index function can be used in table calculations to extract and manipulate the value of a pivoted column based on its index (in other words, its position).
Syntax
pivot_index(expression, pivot_index)
The pivot_index function evaluates expression in the context of the pivot column at the position pivot_index (1 for first pivot, 2 second pivot, etc.) The function returns null for unpivoted results.
Examples
The image below shows a query that includes the number of companies that were acquired or not acquired in each business category. We've also included a table calculation that displays the total number of companies in each category:
The formula used to achieve this is:
pivot_index(${companies.count}, 1) + pivot_index(${companies.count}, 2)
This simply adds the first pivot column to the second pivot column.
Things to know
pivot_index cannot be used in a custom filter.
