CREATE TABLE Persons ( P_Id int NOT NULL, LastName varchar(255) NOT NULL, FirstName varchar(255), PRIMARY KEY (P_Id) ) CREATE TABLE Orders ( O_Id int NOT NULL PRIMARY KEY, OrderNo int NOT NULL, P_Id int FOREIGN KEY REFERENCES Persons(P_Id) )
创建表格订单时出现错误:
ORA-00907:右括号缺失
如果要使用列定义内联定义外键,则不应指定FOREIGN KEY。从定义中删除它。
试试这个:
CREATE TABLE Orders ( O_Id int NOT NULL PRIMARY KEY, OrderNo int NOT NULL, P_Id int REFERENCES Persons(P_Id) )
