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.

  • 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(fact, decimal)
SELECT PERCENTILE(fact, percentage)
SELECT PERCENTILE((SELECT SUM([metric]) BY [attribute]), decimal)
