Answer 1

TRUNCに余分なブラケットを取り外して、以下のクエリを実行してください：

SELECT c.customer# "C#", o.order# "ORDER#", 
o.orderdate "ORDER DATE", 
NVL2(o.shipdate, 'Not shipped', 'shipped'), 
o.shipdate "Ship date", 
o.shipdate-o.orderdate "lead time in days", 
TRUNC((o.shipdate-o.orderdate)/30,2) "lead time in months" 
FROM customers c, orders o 
ORDER BY "lead time in days" DESC, c.customer# ASC, o.order# ASC;
