Question

我的数据库出了问题。我创建了表：

CREATE TABLE TOURNAMENT
  (
    TOURNAMENT_ID   INTEGER NOT NULL,
    DATE            DATE NOT NULL,
    CITY            VARCHAR2 (100 CHAR) NOT NULL,
    PRIZEPOOL       NUMBER (18,2) NOT NULL,
    COUNTRY         VARCHAR2 (100 CHAR) NOT NULL,
    ARENA           VARCHAR2 (100 CHAR),
    SHOP_ID         INTEGER,
    PRODUCTION_ID   INTEGER NOT NULL
  );

ALTER TABLE TOURNAMENT ADD CONSTRAINT TOURNAMENT_PK PRIMARY KEY ( TOURNAMENT_ID ) ;

当我尝试插入一行：

prompt Tabulka TOURNAMENT

insert into TOURNAMENT (TOURNAMENT_ID, DATE, CITY, PRIZEPOOL, COUNTRY, ARENA, SHOP_ID, PRODUCTION_ID)
values (1, 08-OCT-2015, 'Moscow', 15000, 'Russia', NULL, 1, 3);

我收到错误消息：

ORA-00984：此处不允许列

有人知道这可能意味着什么吗？

Answer 1

这应该有效 -

CREATE TABLE TOURNAMENT
  (
    TOURNAMENT_ID   INTEGER NOT NULL ,
    TOURNAMENT_DATE       DATE NOT NULL ,
    CITY       VARCHAR2 (100 CHAR) NOT NULL ,
    PRIZEPOOL   NUMBER (18,2) NOT NULL ,
    COUNTRY        VARCHAR2 (100 CHAR) NOT NULL ,
    ARENA       VARCHAR2 (100 CHAR) ,
    SHOP_ID   INTEGER ,
    PRODUCTION_ID INTEGER NOT NULL
  ) ;
ALTER TABLE TOURNAMENT ADD CONSTRAINT TOURNAMENT_PK PRIMARY KEY ( TOURNAMENT_ID ) ;



insert into TOURNAMENT (TOURNAMENT_ID, TOURNAMENT_DATE, CITY, PRIZEPOOL, COUNTRY, ARENA, SHOP_ID, PRODUCTION_ID) values (1, TO_DATE('08-OCT-2015','DD-MON-YYYY'), 'Moscow', 15000, 'Russia', NULL, 1, 3);

你正在以错误的方式写日期值;一种方式可以是ANSI格式：

INSERT INTO TOURNAMENT(
                       TOURNAMENT_ID,
                       DATE_,
                       CITY,
                       PRIZEPOOL,
                       COUNTRY,
                       ARENA,
                       SHOP_ID,
                       PRODUCTION_ID
                      )
     VALUES (
             1,
             DATE '2015-10-08',
             'Moscow',
             15000,
             'Russia',
             NULL,
             1,
             3
            );

或者，如果您想保留所显示的格式，请使用to_date：

to_date('08-OCT-2015', 'DD-MON-YYYY')

此外，DATE是一个保留字，你最好避免使用它来命名表格列。
