Subj:   Re: PERCENT_RANK
 
From:   JC Sheu

I am not aware of "PERCENT_RANK" function. But if you are trying to rank something by percentile (or quantile or any other number of segments), you can use the "QUANTILE" function. For example:

SELECT    customer_ID
         ,QUANTILE(100, customer_revenue)

FROM ...

will return customer ID and customer's revenue rank in percentile (0-99).

Remember to use "QUALIFY" instead of "HAVING" to filter out unwanted records.


Hope this will help!

JC
