How can combine the secon query below into the first one using subquery? Thanks.
SELECT  SUM(ORDERITEMS.qty*INVENTORY.PRICE) / COUNT(DISTINCT ORDERS.ORDERID) AS 'Orders_Average'
    AS 'OrderItems_Average'
  FROM  ORDERITEMS LEFT OUTER JOIN
               INVENTORY ON ORDERITEMS.PARTID = INVENTORY.PARTID RIGHT OUTER JOIN
               ORDERS ON ORDERITEMS.ORDERID = ORDERS.ORDERID
 
           UNION ALL 
   
               SELECT  SUM(ORDERITEMS.qty*INVENTORY.PRICE) / COUNT(DISTINCT ORDERITEMS.ORDERID) AS 'OrderItems_Average'
   AS 'OrderItems_Average'
  FROM  ORDERITEMS LEFT OUTER JOIN
               INVENTORY ON ORDERITEMS.PARTID = INVENTORY.PARTID RIGHT OUTER JOIN
               ORDERS ON ORDERITEMS.ORDERID = ORDERS.ORDERID

adding this query: SELECT SUM(ORDERITEMS.qty*INVENTORY.PRICE) / COUNT(DISTINCT ORDERITEMS.ORDERID) AS 'OrderItems_Average'
AS 'OrderItems_Average'
FROM ORDERITEMS LEFT OUTER JOIN
INVENTORY ON ORDERITEMS.PARTID = INVENTORY.PARTID RIGHT OUTER JOIN
ORDERS ON ORDERITEMS.ORDERID = ORDERS.ORDERID


to this one as a subquery

SELECT SUM(ORDERITEMS.qty*INVENTORY.PRICE) / COUNT(DISTINCT ORDERS.ORDERID) AS 'Orders_Average'
AS 'OrderItems_Average'
FROM ORDERITEMS LEFT OUTER JOIN
INVENTORY ON ORDERITEMS.PARTID = INVENTORY.PARTID RIGHT OUTER JOIN
ORDERS ON ORDERITEMS.ORDERID = ORDERS.ORDERID
