ANY Function

Extracts a non-null and non-missing value from a specified column. If all values are missing or null, the function returns a null value.

This function is intended to be used as part an aggregation to return any single value. When run at scale, there is some randomness to the value that is returned from the aggregated groupings, although randomness in not guaranteed.

In a flat aggregation, in which no aggregate function is applied, it selects the first value that it can retrieve from a column, which is the first value. This function has limited value outside of an aggregation. See Pivot Transform.

Input column might be of Integer, Decimal, String, Object, or Array type.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.

Example - Aggregating on one customer per month

You want to do some sampling of customer orders on a monthly basis. For your sample, you want to select the sum of orders for one customer each month.

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

dateformat(Date, 'MMM')

Parameter: New column name

'month_Date'

You should now have a new column with three-letter month abbreviations. You can use the following aggregation to gather the sum of one customer's orders for each month:
