Hi all,

Does my sql need any tuning??

1.
select distinct c.customer_id, c.cust_first_name || ' ' ||c.cust_last_name customer_name
from customers c, orders o
where c.customer_id = o.customer_id;

2.
select od.order_id, oi.product_id, oi.unit_price
from orders od, order_items oi
where od.order_id = oi.order_id and upper(oi.last_update_user) = 'MINNY';

can anyone help??
