Question

我根据下图创建了两个表：

我现在正在尝试使用测试数据填充这些表，并且我无法在PositionLogEntry表中插入日期类型列而收到错误：PL / SQL：ORA-00984：此处不允许列。

declare

noOfFlights   constant int:= 10;
noOfLog       constant int:=100;

begin

for m in 1..noOfFlights loop

insert into Flight (aircraftRegistration, DateAndTimeDeparture,pilotInCommand)
values              (
                    'Aircraft Registration' || to_char(sqFlight.nextval),
                    to_date('2000-01-01 00:00:00', 'YYYY-MM-DD hh24:mi:ss')
                    + to_ymInterval(to_char(floor(dbms_random.value(1,30))) || '-' || to_char(floor(dbms_random.value(1,12)))),
                    'Pilot in Command' || to_char(sqFlight.currval));
                    end loop;

for c in 1..noOfLog loop
    for m in (select AIRCRAFTREGISTRATION, DATEANDTIMEDEPARTURE from Flight) loop

insert into POSITIONLOGENTRY (AIRCRAFTREGISTRATION, DATEANDTIMEDEPARTURE, logTime, positionLatitude, positionLongtitude, courseDegrees, headingDegree, horizontalSpeedKnots,
  verticalSpeedKnots, altitudeFeet, altitudeFlightLevels) values
  (
    AIRCRAFTREGISTRATION,
    DATEANDTIMEDEPARTURE,
    to_date('2000-01-01 00:00:00', 'YYYY-MM-DD hh24:mi:ss')
    + to_ymInterval(to_char(floor(dbms_random.value(1,30))) || '-' || to_char(floor(dbms_random.value(1,12)))),
    round(dbms_random.value(7,0)),
    round(dbms_random.value(7,0)),
    round(dbms_random.value(3,0)),
    round(dbms_random.value(3,0)),
    round(dbms_random.value(3,0)),
    round(dbms_random.value(3,0)),
    round(dbms_random.value(4,0)),
    round(dbms_random.value(4,0)));
    end loop;

end loop;

/commit;/

end;

P.S。 Flight表格正确填充。你能否提出任何可能的解决方案？谢谢！

Answer 1

您不能在AIRCRAFTREGISTRATION, DATEANDTIMEDEPARTURE子句中使用列名VALUES等。

使用

m.AIRCRAFTREGISTRATION,
m.DATEANDTIMEDEPARTURE

代替。

将日期类型值插入Oracle中的表：ORA-00984
