Built-in Functions → index

index() is an analytic function that returns the index of each row based on the order of the grouped values. For identical values, the index order is not guaranteed.

The following table illustrates the behavior of the index() analytic function:

Category Product Min List Price index()
Fruit Apple 0.25 1
Fruit Orange 0.35 2
Fruit Banana 0.40 3
Fruit Lemon 0.40 4
Fruit Kiwi 0.75 5
Fruit Plum 0.75 6
Fruit Apricot 0.75 7
Fruit Yellow Melon 3.50 8
Fruit Cantaloupe 3.50 9
Fruit Pineapple 5.00 10


index(groupBy, orderBy)

index(groupBy(Dimension,...), orderBy(aggregation_function(measure), true/false,...))

The following table illustrates the index() function parameters:

Parameter Description
groupBy(Dimension,…) Grouping function that specifies which group of data to operate over based on a dimension column, such as Product Category or Subcategory
orderBy() Sorting function that specifies the order of rows based on an aggregation and a boolean value
aggregation_function(measure) Aggregation function, such as min or max, that performs a calculation on a set of values for a measure, such as List Price or Cost, and returns a single value for each set
True Enables an ascending order
False Enables a descending order


int representing the index of each value in the column.


Find the index of a product within a product category based on the minimum list price.
