SQL創建表缺少圓括號

Question

我正在運行這兩個命令來創建新表，但第二個創建表命令不斷給我錯誤。

CREATE TABLE TEAMSTADIUM(
stadium_name varchar2(40) not null, 
stadium_max_capcity number(10) not null, 
stadium_field_serface varchar2(40) not null, 
stadium_year_built number(4) not null, 
stadium_location varchar2(40) not null, 
Primary KEY(stadium_name) 
) 


CREATE TABLE TEAMINFO(
team_name varchar2(40) not null, 
team_owner varchar2(40) not null, 
team_coach varchar2(40) not null, 
team_created Date() not null, 
PRIMARY KEY(team_name) 
foreign key(stadium_name) references TEAMSTADIUM(stadium_name) 
) 

Answer 1

你TEAMINFO表引用TEAMSTADIUM.stadium_name後放;，但有自己的沒有這樣的列。添加它，確保它具有相同的數據類型作爲父表：

CREATE TABLE TEAMINFO(
    team_name varchar2(40) not null, 
    team_owner varchar2(40) not null, 
    team_coach varchar2(40) not null, 
    team_created Date not null, 
    -- Remove() ^^ 
    -- This column must exist in both tables 
    stadium_name varchar2(40) not null, 
    PRIMARY KEY(team_name), 
    -- missing comma  ^^ 
    foreign key(stadium_name) references TEAMSTADIUM(stadium_name) 
) 

運用上述三種修改後，它會正確執行：如果這不是你的問題http://sqlfiddle.com/#!4/883a4

嘗試使用Date not null;和茶几的每個)

CREATE TABLE TEAMINFO(
    stadium_name varchar2(40) not null, 
    team_name varchar2(40) not null, 
    team_owner varchar2(40) not null, 
    team_coach varchar2(40) not null, 
    team_created Date not null, 
    PRIMARY KEY(team_name), 
    foreign key(stadium_name) references TEAMSTADIUM(stadium_name) 
);
