SQL - 缺少右括号

SQL - Missing right parenthesis(SQL - 缺少右括号)

问题描述

我正在尝试在 Oracle 11g 中执行此脚本并收到以下错误，我不知道我在哪里缺少括号或错误是什么，请帮助我解决这个问题.

I am trying to execute this script in Oracle 11g and getting the following error, I dont know where I am missing the paranthesis or what is the mistake kindly help me figure this out.

脚本:

CREATE TABLE User_Role ( 
  user_role_id INT  NOT NULL  , 
  Users_user_id INT  FOREIGN KEY REFERENCES Users(user_id), 
  User_Types_user_type VARCHAR(20) FOREIGN KEY REFERENCES User_Types(user_type),  
  PRIMARY KEY(user_role_id) 
)

错误:

ORA-00907:缺少右括号

ORA-00907: missing right parenthesi

推荐答案

删除 FOREIGN KEY 子句.如下重写您的 CREATE TABLE 语句:

Delete FOREIGN KEY clause. Rewrite your CREATE TABLE statement as follows:

CREATE TABLE User_Role ( 
      user_role_id         INT  NOT NULL  , 
      Users_user_id        INT  REFERENCES Users(user_id), 
      User_Types_user_type VARCHAR(20) REFERENCES User_Types(user_type),  
      PRIMARY KEY(user_role_id) 
    )

在这种情况下，约束名称将由 Oracle 生成.如果你想给他们更有意义的名字，你可以写你的 create table 语句如下:

In this case constraint names will be generated by Oracle. If you want to give them more meaningful names you could write your create table statement as follows:

  CREATE TABLE User_Role1 ( 
      user_role_id         INT  NOT NULL  , 
      Users_user_id        INT  , 
      User_Types_user_type VARCHAR(20) ,  
      constraint PK_YourTable PRIMARY KEY(user_role_id), 
      constraint FK_Table_1 foreign key(Users_user_id) REFERENCES Users(user_id),
      constraint FK_Table_2 foreign key(User_Types_user_type) REFERENCES User_Types(user_type)
    )
