Question

我刚开始学习PostgreSQL，我在将文本文件中的数据插入表格时遇到了很多麻烦。这是学校的任务，所以sql代码和文本文件都是我老师写的。这样我知道文件实际上没有任何问题。

sql代码：

drop view if exists Timeantall;
drop view if exists Varighet;
drop table if exists Timelistelinje;
drop table if exists Timeliste;

create table Timeliste (
 timelistenr int primary key,
 status text not null,
 levert date,
 utbetalt date,
 beskrivelse text not null,
 check (status = 'aktiv' or status = 'levert' or status = 'utbetalt')
 );

create table Timelistelinje (
 timelistenr int references Timeliste(timelistenr),
 linjenr int,
 startdato date not null,
 starttid time not null,
 sluttid time,
 pause int,
 beskrivelse text not null,
 primary key (timelistenr, linjenr)
 );

 create view Varighet AS
   select timelistenr,
     linjenr, 
     (sluttid - starttid - pause) as varighet
   from (select timelistenr,
           linjenr,
           cast(extract(hour from starttid) as integer)*60 +
                cast(extract(minute from starttid) as integer) as starttid,
           cast(extract(hour from sluttid) as integer)*60 +
                cast(extract(minute from sluttid) as integer) +
                     case when sluttid < starttid then 60*24
                          else 0
                     end as sluttid,
           case when pause is null then 0
                else pause
           end as pause
    from Timelistelinje
    where sluttid is not null) as c;

 create view Timeantall AS
   select timelistenr, ceil(cast(minuttantall as real)/60) as timeantall
  from (select timelistenr, sum(varighet) as minuttantall
    from Varighet
    group by timelistenr) as m;

  \copy Timeliste from 'timeliste.txt' with delimiter '|' null ''

  \copy Timelistelinje from 'timelistelinje.txt' with delimiter '|' null ''

\ copy命令出现问题，这是错误消息：

psql:timelistedb.sql:51: ERROR:  invalid byte sequence for encoding "UTF8": 
0xf8
CONTEXT:  COPY timeliste, line 2
psql:timelistedb.sql:53: ERROR:  invalid byte sequence for encoding "UTF8": 
0xf8
CONTEXT:  COPY timelistelinje, line 3

以下是我的文字文件：

我完全不知道如何解决这个问题，我已经尝试了很多谷歌搜索，但没有一个解决方案有所帮助。任务的截止日期也即将来临，我甚至还没有开始，因为我似乎无法超越这个。

非常感谢任何帮助！

验证文件的编码是UTF-8。确保将其保存为UTF-8，如果不是，请在运行复制命令时指定正确的编码。

例如，如果文件来自MS Office文件，则可能是WIN 1250的编码。以下是在调用副本时如何更改编码的示例：

copy Timeliste from 'timeliste.txt' with delimiter '|' null '' encoding 'WIN1250'

无法将文本文件中的数据复制到psql中的表中
