{code:java}
SELECT DISTINCT
(SELECT COUNT(ORDERS.CUSTOMER_ID) FROM ORDERS),
(SELECT COUNT(DISTINCT ORDERS.CUSTOMER_ID) FROM ORDERS),
(SELECT COUNT(ORDERS.ORDER_ID) FROM ORDERS),
(SELECT COUNT(DISTINCT ORDERS.ORDER_ID) FROM ORDERS)
FROM ORDERS
;
{code}
It's working for me.

Try this:

{noformat}
connect 'jdbc:derby:memory:db;create=true';

CREATE TABLE t(userName VARCHAR(50), product VARCHAR(50));

SELECT
  (SELECT DISTINCT userName FROM t) userCount,
  (SELECT DISTINCT product FROM t) productCount
FROM sysibm.sysdummy1;
{noformat}
