Question

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.

Script:

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) 
)

Error:

ORA-00907: missing right parenthesi

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) 
    )

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)
    )
