创建表时遇到问题

Question

我试图让两个 table 执行，但我不断收到错误。事务 table 说它不能在没有创建另一个的情况下执行，然后我尝试创建代理 table 并且它说缺少右括号

SQL Error: ORA-00907: missing right parenthesis

但我检查了我的代码，它看起来不错。你们中有人知道问题出在哪里吗？感谢所有评论的人！

    Create table Broker
(
    Broker_Number Number(7,0)
      Constraint PK_Broker_Broker_Number Primary Key
      Constraint NN_Broker_Broker_Number Not Null,
   First_Name Varchar2(25)
      Constraint NN_Broker_First_Name Not Null,
   Last_Name Varchar2(3O)
      Constraint NN_Broker_Last_Name Not Null,
   Area_Code Number(3,0)
      Default '780'
      Constraint NL_Broker_Area_Code Null,
   Phone_Number Number(7,0)
      Constraint NL_Broker_Phone_Number Null,
   Email_Address Varchar2(50)
      Constraint CK_Broker_Email_Address Check (REGEXP_like(Email_Address,'%@%.%'))
      Constraint NN_Broker_Email_Address Not Null
);


Create table Transaction
(
  Portfolio_Number Number(7,0) Not Null,
      Constraint FK_Trans_Portfolio_Number
      Foreign Key (Portfolio_Number)
      References Portfolio(Portfolio_Number),
  Stock_Code Varchar2(10) Not Null,
      Constraint FK_Transaction_Stock_Code
      Foreign Key (Stock_Code)
      References Stock(Stock_Code),
  Transaction_Date Date
      Constraint PK_Trans_Transaction_Date Not Null,
  Exchange_Code Varchar2(4) Not Null,    
      Constraint FK_Transaction_Exchange_Code
      Foreign Key (Exchange_Code)
      References Exchange(Exchange_Code),
  Broker_Number Number(7,0) Not Null,
      Constraint FK_Transaction_Broker_Number
      Foreign Key (Broker_Number)
      References Broker(Broker_Number),
  Buy_Sell Char(1)
      Constraint CK_Transaction_Buy_Sell Check (Buy_Sell in ('B','S') )
      Constraint NN_Transaction_Buy_Sell Not Null,
  Quantity Number(7,0)
      Constraint NN_Transaction_Quantity Not Null,
  Price_Per_Share Number(6,2)
      Constraint NN_Transaction_Price_Per_Share Not Null
)

Answer 1

就是这条线

Last_Name Varchar2(3O)

那不是30，是3O，就是数字三后面的字母O。

调试此类错误语句的一种方法是一次删除一列，运行语句，然后重复该过程，直到不再遇到错误。在这种情况下，我删除了这一特定行并且它工作正常。那时我注意到编辑器中的 O 而不是 0。
