Returns the maximum value from a list of 2 or more fields or expressions.
NARY_MAX is similar to MAX, except that it allows you to compare multiple values.
Sample usage
NARY_MAX(Event_1, Event_2, Event_3)
Syntax
NARY_MAX(X, Y, [,Z]*)
Parameters
X, Y, Z- fields or expressions to be evaluated.
Example 1
This example shows how you can mix fields, calculations, and literals in an NARY_MAX function:
NARY_MAX(REVENUE, (COST * 2), 10, SESSIONS))
Example 2
Suppose you want to determine the maximum sales for your 3 sales regions by date and that your data looks like this:
| Date | Region 1 Sales | Region 2 Sales | Region 3 Sales |
| Date 1 | 100 | 200 | 150 |
| Date 2 | 75 | 130 | 150 |
| Date 3 | 225 | 185 | 230 |
You could use the NARY_MAX function to determine the maximum sales for a given date:
| Example formula | Date | |
|---|---|---|
NARY_MAX(Region 1 Sales, Region 2 Sales, Region 3 Sales,) |
Date 1 | 200 |
| Date 2 | 150 | |
| Date 3 | 230 |
Notes
NARY_MAX requires at least 2 arguments. At least one argument must be a field or an expression containing a field.
NARY_MAX works on numeric fields or expressions only. If you apply this function to other data types, you'll get an error.
