# PERCENTILE

The PERCENTILE( ) function returns the specified percentile out of some set of values. This could be useful for establishing a threshold of acceptance, such as for candidates who score above the 90th percentile on a certification exam, or rewarding sales reps in the top percentile with regard to deals won in the past year.

Formats:

``PERCENTILE(numeric, k)``
• where numeric is a fact or metric
• where k is a value between 0 and 1 representing the percentile you want returned specified as a decimal. k accepts constants as inputs. Numeric values must be expressed in the following format: 0.xx
• For metric expressions, you should compute percentiles using syntax similar to the following:

``SELECT PERCENTILE((SELECT SUM([fact]) BY [attribute]),0.25)``
``PERCENTILE(numeric, k%)``
• where numeric is a fact or metric
• where k% is a number between 0 and 100 representing the percentile you want returned. k accepts constants as inputs, followed by percent signs as inputs.
• For metric expressions, you should compute percentiles using syntax similar to the following:

``SELECT PERCENTILE((SELECT SUM([fact]) BY [attribute]),25%)``

Syntax

``````SELECT PERCENTILE(…) [ASC|DESC] [BY(…)]
SELECT PERCENTILE(metric, decimal)
SELECT PERCENTILE(metric, percentage)
SELECT PERCENTILE(fact, decimal)
SELECT PERCENTILE(fact, percentage)
SELECT PERCENTILE((SELECT SUM([metric]) BY [attribute]), decimal)
SELECT PERCENTILE((SELECT SUM([metric]) BY [attribute]), percentage)``````

Examples

``````SELECT PERCENTILE(Amount, 0.75)
SELECT PERCENTILE(Amount, 75%)``````
