Python操作Oracle--连接问题

1. [atyu30@ns138 mediawiki]$ python
   
2. Python 2.4.3 (#1, Jun 11 2009, 14:09:37)
   
3. [GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
   
4. Type "help", "copyright", "credits" or "license" for more information.
   
5. >>> import cx_Oracle
   
6. >>> db = cx_Oracle.connect('atyu30','atyu30','10.0.20.47:1521/YUYIZHI')
   
7. Traceback (most recent call last):
   
8.   File "", line 1, in ?
   
9. TypeError: argument 1 must be unicode, not str
   
10. >>> db1 = cx_Oracle.connect('atyu30/atyu30@10.0.20.47:1521/YUYIZHI')
    
11. Traceback (most recent call last):
    
12.   File "", line 1, in ?
    
13. TypeError: argument 1 must be unicode, not str

同样的方式在windows下操作就没问题

1. Python 3.1.2 (r312:79149, Mar 21 2010, 00:41:52) [MSC v.1500 32 bit (Intel)] on win32
   
2. Type "copyright", "credits" or "license()" for more information.
   
3. >>> import cx_Oracle
   
4. >>> conn = cx_Oracle.connect('atyu30','atyu30','10.0.20.47:1521/YUYIZHI')
   
5. >>>
   
6. 
   
7. >>> cursor = conn.cursor()
   
8. >>> cursor.execute("""create table python_oracle(id number,name varchar2(50),password varchar(50),primary key(id))""")
   
9. >>> cursor.execute("""insert into python_oracle values(1,'admin','password')""")

正确方法：

1. [oracle@storage ~]$ python
   
2. Python 2.4.3 (#1, Jun 11 2009, 14:09:37)
   
3. [GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
   
4. Type "help", "copyright", "credits" or "license" for more information.
   
5. >>> import cx_Oracle
   
6. >>> db = cx_Oracle.connect("atyu30/atyu30@//10.0.20.47/YUYIZHI")
   
7. >>>
