Oracle 创建表并看到此错误-ORA-00907:缺少右括号

有人能帮我理解我错过了什么吗？我不明白错误是从哪里来的。

它不是

CREATE TABLE Office(
       Office_ID INT NOT NULL GENERATED BY DEFAULT AS IDENTITY,
       Phone_Number CHAR(11) NOT NULL,
            CONSTRAINT Office_PK PRIMARY KEY (Office_ID));
CREATE TABLE Faculty(
       Faculty_ID INT NOT NULL GENERATED BY DEFAULT AS IDENTITY,
       First_Name VARCHAR(25) NOT NULL,
       Last_Name VARCHAR (25) NOT NULL,
       Office_ID INT NOT NULL,
            CONSTRAINT Faculty_PK PRIMARY KEY (Faculty_ID) 
            CONSTRAINT Faculty_FK FOREIGN KEY (Office_ID) REFERENCES Office(Office_ID));
CREATE TABLE Student(
       Student_ID INT NOT NULL GENERATED BY DEFAULT AS IDENTITY,
       First_Name VARCHAR(25) NOT NULL,
       Last_Name VARCHAR(25) NOT NULL,
       Phone_Number CHAR(11) NOT NULL,
       Sposue_Name VARCHAR (30),
       Street_Address VARCHAR(30) NOT NULL,
       City VARCHAR(20) NOT NULL,
       State CHAR(2) NOT NULL,
       Zip VARCHAR(9) NOT NULL,
       Advisor_ID INT NOT NULL,
            CONSTRAINT Student_PK PRIMARY KEY (Student_ID) 
            CONSTRAINT Student_FK FOREIGN KEY (Advisor_ID) REFERENCES Faculty(Faculty_ID));

但是

（

notnull

最后一个）

---

另外，在最后两个表中，

CONSTRAINT

语句的末尾缺少逗号

一旦你解决了这个问题，它就可以正常工作了

Office_ID INT GENERATED BY DEFAULT AS IDENTITY NOT NULL,

约束是表的属性，需要用逗号分隔，就像列一样。

Office_ID INT GENERATED BY DEFAULT AS IDENTITY NOT NULL,

SQL> CREATE TABLE Office(
  2         Office_ID INT GENERATED BY DEFAULT AS IDENTITY NOT NULL ,
  3         Phone_Number CHAR(11) NOT NULL,
