将整个表复制到另一个除了在Oracle中的一列之外

Question

在下面的代码中，我尝试将表中的内容复制到除一列之外的另一列。对于那个特定的列，我想从第三个表中插入一个值，其中来自不同表的两列匹配。

insert into PlaneKeyLookup (launchtime, landingtime, flightduration, 
       planeid, pilot1init, pilot2init, launchtype, kmsflown) values 
((select launchtime from NewFlightsTransformed), 
(select landingtime from NewFlightsTransformed), 
(select flightduration from NewFlightsTransformed), 
(select dp.id from D_Plane dp where exists 
    (select nf.planeregistration from NewFlightsTransformed 
    where dp.registration = nf.planeregistration)), 
(select pilot1init from NewFlightsTransformed), 
(select pilot2init from NewFlightsTransformed), 
(select launchtype from NewFlightsTransformed), 
(select kmsflown from NewFlightsTransformed)); 

有什么建议吗？

你想会更喜欢的SQL：

insert into PlaneKeyLookup (launchtime, landingtime, flightduration, 
       planeid, pilot1init, pilot2init, launchtype, kmsflown) 
select launchtime, 
     landingtime, 
     flightduration, 
     (select dp.id from D_Plane dp where...), 
     pilot1init, 
     pilot2init, 
     launchtype, 
     kmsflown 
    from NewFlightsTransformed; 

我不知道到底是为planeid查询应该是什么，但它必须返回1行，让你wnat的ID为NewFlightsTransformed行它随之而来。它可以是相关与外部查询如果需要的话（可能）：

(select dp.id from D_Plane dp 
    where dp.xxx = NewFlightsTransformed.xxx 
    and ...) 

也许：

(select dp.id from D_Plane dp where dp.registration = nf.planeregistration) 

即

insert into PlaneKeyLookup (launchtime, landingtime, flightduration, 
       planeid, pilot1init, pilot2init, launchtype, kmsflown) 
select launchtime, 
     landingtime, 
     flightduration, 
     (select dp.id from D_Plane dp where dp.registration = nf.planeregistration), 
     pilot1init, 
     pilot2init, 
     launchtype, 
     kmsflown 
    from NewFlightsTransformed nf;
