如何在MongoDB中执行存储过程/函数

我是mongo的新手，我可以从aggregate创建它，但我想使用这两个表创建一个函数或某种存储过程，它应该包含Customer Customer\u NO、FNAME、LNAME、sum（SHIPPING\u CHARGE）、sum（TAX\u AMT）、sum（TOTAL\u AMT）、count（*）

为了了解这一点，我想将下面的存储过程应用到MongoDB中，并在其中添加一些列

SET SERVEROUTPUT ON
CREATE OR REPLACE PROCEDURE GET_NUM_ORDERS(CUST_NO IN OES2.CUSTOMER.CUSTOMER_NO%TYPE, TOTAL_ORDERS OUT NUMBER) IS
  CURSOR CURS IS SELECT COUNT(*) FROM OES2.ORDERS WHERE CUSTOMER_NO = CUST_NO;
BEGIN
  OPEN CURS;
  FETCH CURS INTO TOTAL_ORDERS;
  CLOSE CURS;
END GET_NUM_ORDERS;
/
DECLARE
TOTAL_ORDERS NUMBER;
BEGIN
  FOR A IN (SELECT CUSTOMER.CUSTOMER_NO, FNAME, LNAME FROM OES2.CUSTOMER)
  LOOP
    GET_NUM_ORDERS(A.CUSTOMER_NO, TOTAL_ORDERS);
    DBMS_OUTPUT.PUT_LINE(A.CUSTOMER_NO || '  ' || A.FNAME || ' ' || A.LNAME || '   ' || TOTAL_ORDERS);
  END LOOP;
END

这是我想要适应MOngoDB的SQL查询

SELECT Customer.CUSTOMER_NO,Customer.LNAME,Customer.FNAME, Customer.FNAME, sum([Order].SHIPPING_CHARGE),
sum([Order].TAX_AMT),sum([Order].TOTAL_AMT), count(*)
    FROM Customer inner join [Order]
    on Customer.CUSTOMER_NO = [Order].CUSTOMER_NO
    GROUP BY Customer.CUSTOMER_NO,Customer.LNAME,Customer.FNAME, Customer.FNAME
    ORDER BY Customer.CUSTOMER_NO;

db.Customer.insertMany([

这在MongoDB中可能吗
