Step-5: Java & SQL Construct

class MyJavaUDF {

    private double x;

    // Constructor
    public MyJavaUDF()  {
        x = Math.random();
    }

    // Handler
    public double myHandler() {
        return x;
    }

    public static void main(String [] args){
        MyJavaUDF mc = new MyJavaUDF();
        System.out.println(mc.myHandler());
    }
}

use role sysadmin;
use database ttips;
use schema udfs;
use warehouse compute_wh;

-- lets list if my jar is available or not
list @~;

create or replace function my_java_udf()
    returns double
    language java
    imports = ('@~/java-udf/MyUDF.jar')
    handler = 'MyJavaUDF.myHandler';
    
desc function my_java_udf();

select my_java_udf(),my_java_udf(),my_java_udf();

select my_java_udf()
union all
select my_java_udf();

show functions like 'MY_JAVA%';
