oracle 表单错误绑定变量

Question

我正在使用后查询来显示我的email_address。

表格

投资组合

Portfolio_Number    PK  Number (7,0)    Not Null
Investor_Number     FK  Number (7,0)    Not Null
Portfolio_Description   Varchar2 (50)   Null

投资者

Investor_Number PK  Number (7,0)    Not Null
First_Name          Varchar2 (25)   Not Null
Last_Name           Varchar2 (30)   Not Null
Email_Address       Varchar2 (50)   Not Null

数据块：投资组合

display item: EMAIL_ADDRESS

post_query：

select Email_address
into :PORTFOLIO.EMAIL_ADDRESS
FROM Inverstor
where Inverstor_number =:PORTFOLIO.Inverstor_number;

第 4 行错误错误绑定变量 PORTFOLIO.Inverstor_number

Answer 1

比较：

      Investor_Number     FK  Number (7,0)    Not Null
      --------

对比

where Inverstor_number =:PORTFOLIO.Inverstor_number;
      ----R----                    ----R----

修正拼写；是investor，不是inveRstor。
