Question

我正在尝试将csv文件中的值插入到我的postgresql数据库中。这是我的桌子：

CREATE TABLE AllocatedEICDetail (
  Id                                    SERIAL NOT NULL, 
  EntityCreatedAt                       timestamp(34) with time zone NOT NULL, 
  EntityModifiedAt                      timestamp(34) with time zone NOT NULL, 
  MRID                                  varchar(250), 
  DocStatusValue                        varchar(250), 
  AttributeInstanceComponent            varchar(250), 
  LongNames                             varchar(250), 
  DisplayNames                          varchar(250), 
  LastRequestDateAndOrTime              timestamp(7), 
  DeactivateRequestDateAndOrTime        timestamp(7), 
  MarketParticipantStreetAddressCountry varchar(250), 
  MarketParticipantACERCode             varchar(250), 
  MarketParticipantVATcode              varchar(250), 
  Description                           varchar(255), 
  EICParentMarketDocumentMRID           varchar(250), 
  ELCResponsibleMarketParticipantMRID   varchar(250), 
  IsDeleted                             bool NOT NULL, 
  CONSTRAINT PK_AllocatedEICDetail 
    PRIMARY KEY (Id));

以及我要插入的数据：

Id;EntityCreatedAt;EntityModifiedAt;MRID;DocStatusValue;AttributeInstanceComponent;LongNames;DisplayNames;LastRequestDateAndOrTime;DeactivateRequestDateAndOrTime;MarketParticipantStreetAddressCountry;MarketParticipantACERCode;MarketParticipantVATcode;Description;EICParentMarketDocumentMRID;ELCResponsibleMarketParticipantMRID;IsDeleted

但是当我尝试将csv文件插入pgAdmin 4时，出现此错误：

错误：类型为timestamp的无效输入语法：“ NULL” 上下文：COPY已分配eicdetail，第2行，列deactivaterequestdateandortime：“ NULL”

有什么想法吗？

Answer 1

该错误消息表示您的输入数据中有一个文字“ NULL”（字符串）。您可能应该尝试将其替换为空值，如下所示：

47677;2019-04-01 09:26:51.2053104 +00:00;2019-04-01 09:26:51.2053104 +00:00;10T-1001-10010AS;A05;International;Tie Line Koman-KosovoB;L_KOM-KOSB;2018-10-31 00:00:00.0000000;;;;;Tieline;;10XAL-KESH-----J;0
