【问题描述】：

这是我的数据：

CREATE TABLE FavoriteBasketballTeams
    TeamName VARCHAR(255) Primary Key,
    DateCreated Date,
    Championships INT NOT NULL,
    FinalsAppearances INT NOT NULL ;
    
INSERT INTO FavoriteBasketballTeams(TeamName,DateCreated,Championships,FinalsAppearances) Values('Nets','1976','0','2');
INSERT INTO FavoriteBasketballTeams(TeamName,DateCreated,Championships,FinalsAppearances) Values('Thunder','1967','1','4');
INSERT INTO FavoriteBasketballTeams(TeamName,DateCreated,Championships,FinalsAppearances) Values('Lakers','1948','17','32');
INSERT INTO FavoriteBasketballTeams(TeamName,DateCreated,Championships,FinalsAppearances) Values('Trailblazers','1970','1','3');

这些是我得到的错误：

【问题讨论】：

在创建表中的字段定义周围插入括号，开始。创建表 FavBasketTeams (teamName ....)。您可以访问 w3schools.com 了解基本 sql。

【解决方案1】：

CREATE TABLE 语句中的表名后半列前需要括号：

CREATE TABLE FavoriteBasketballTeams(
    TeamName VARCHAR(255) Primary Key,
    DateCreated Date,
    Championships INT NOT NULL,
    FinalsAppearances INT NOT NULL
);

那么'1976' 是字符串文字，而不是日期。 Oracle 尝试将其解析为日期，但格式不正确；您可以使用 TO_DATE('1976','YYYY') 但这会将日期的月份设置为当年的当前月份，因此使用日期文字 DATE '1976-01-01' 并将月份和日期组件设置为年初可能会更好（或进行一些研究并将其设置为他们成立的实际日期）。另外，当你有一个数字列时，你不应该将值作为字符串传递，只需使用一个数字：

INSERT INTO FavoriteBasketballTeams(
  TeamName,DateCreated,Championships,FinalsAppearances
) Values(
  'Nets',DATE '1976-01-01',0,2
);

INSERT INTO FavoriteBasketballTeams(
  TeamName,DateCreated,Championships,FinalsAppearances
) Values(
  'Thunder', DATE '1967-01-01',1,4
);

INSERT INTO FavoriteBasketballTeams(
  TeamName,DateCreated,Championships,FinalsAppearances
) Values(
  'Lakers', DATE '1948-01-01',17,32
);

INSERT INTO FavoriteBasketballTeams(
  TeamName,DateCreated,Championships,FinalsAppearances
) Values(
  'Trailblazers',DATE '1970-01-01',1,3
);
