QUANTILE_CONT
Aggregate function.
The QUANTILE_CONT() function computes the interpolated quantile number of a numeric data sequence.
caution
NULL values are not counted.
Syntax
QUANTILE_CONT(<levels>)(<expr>)
QUANTILE_CONT(level1, level2, ...)(<expr>)
Arguments
Arguments | Description |
---|---|
<level(s) | level(s) of quantile. Each level is constant floating-point number from 0 to 1. We recommend using a level value in the range of [0.01, 0.99] |
<expr> | Any numerical expression |
Return Type
Float64 or float64 array based on level number.
Example
Create a Table and Insert Sample Data
CREATE TABLE sales_data (
id INT,
sales_person_id INT,
sales_amount FLOAT
);
INSERT INTO sales_data (id, sales_person_id, sales_amount)
VALUES (1, 1, 5000),
(2, 2, 5500),
(3, 3, 6000),
(4, 4, 6500),
(5, 5, 7000);
Query Demo: Calculate 50th Percentile (Median) of Sales Amount using Interpolation
SELECT QUANTILE_CONT(0.5)(sales_amount) AS median_sales_amount
FROM sales_data;
Result
| median_sales_amount |
|-----------------------|
| 6000.0 |
