Explore Databend's UDF Script
Databend currently adds UDF Script support, and JavaScript can be used as a UDF script.
For example, you can define a function with the following statement gcd:
CREATE FUNCTION gcd (INT, INT) RETURNS BIGINT LANGUAGE javascript HANDLER = 'gcd_js' AS $$
export function gcd_js(a, b) {
while (b != 0) {
let t = b;
b = a % b;
a = t;
}
return a;
}
$$
UDF Script support for the Python language is being advanced in an orderly manner.
