Question

我需要一个具有列account name,account id,date created,balance & address的表。在这种情况下，帐户名有2个列，名为first name & last name & address有5列line1,line2,city,state,pincode。使用嵌套表是实现此目的的最佳方法吗？

我尝试使用python中的cx_Oracle模块为oracle-11g创建嵌套表，但它给了我错误，但我无法解决。代码如下：

`self.CUR.execute(""" CREATE TYPE ADDRESS_SUB_COLUMNS AS OBJECT(
                             line1   VARCHAR2(30),
                             line2   VARCHAR2(30),
                             city    VARCHAR2(20),
                             state   VARCHAR2CHAR(10),
                             zip     CHAR(6) 
                             );
                             /""")

        self.CUR.execute(""" CREATE TYPE ADDRESS_TABLE IS TABLE OF ADDRESS_SUB_COLUMNS;
                             /""")

        self.CUR.execute("""CREATE TABLE CUSTOMERS (
                             custid  VARCHAR2(14),
                             address ADDRESS_TABLE )NESTED TABLE address STORE AS customer_addresses""")`

我遇到的错误是：

`Traceback (most recent call last):
  File "python/home.py", line 386, in <module>
    menuObject = mainMenu()
  File "python/home.py", line 133, in __init__
    super().__init__(self.cur)  #Call to constructor in parent2 (TABLE_USERS) : passing cur from parent1
  File "python/home.py", line 72, in __init__
    self.createTable()
  File "python/home.py", line 93, in createTable
    /""")

ORA-06550: line 0, column 0:

）`

有人可以帮我吗？

“ /”字符是SQL * Plus命令终止符。您不能在cx_Oracle中使用它。试试

self.CUR.execute(""" CREATE TYPE ADDRESS_SUB_COLUMNS AS OBJECT(
                             line1   VARCHAR2(30),
                             line2   VARCHAR2(30),
                             city    VARCHAR2(20),
                             state   VARCHAR2CHAR(10),
                             zip     CHAR(6) 
                             );""")

我会让“最佳”问题成为练习。
