percentile — aggregate function to return value closest to the specified percentile rank


percentile (T column, double pct)


This function returns the value of the specified column with percentile rank equal to the specified pct value. If there is no value at exactly pct percentile, then the value with the greatest percentile less than pct is returned. The data type of the specified column (and of the corresponding returned value) must be one of the comparable types in the expression language, as listed on the Data Types page.

As of 10.4.4, this function is deprecated but still supported for backward compatibility.


This LiveView aggregate function is based on the percentile aggregate function in the StreamBase expression language.
