Question

我可以使用sqlplus使用：

登录我的oracle实例

$ env | grep -E '(TWO|SID)'
TWO_TASK=TEST
$ sqlplus me/my_password@TEST

然后我可以毫无问题地运行以下查询：

select 
  persons.person.key AS id,
  persons.person.lname as lastname,
  persons.person.fname as firstname,
  sid.organizations.org_code as org,
  sid.organizations.division_code as division,
  sid.organizations.directorate_code as directorate,
  persons.person.status as status
from
   persons.person,
   sid.organizations
where
   persons.person.dept_id=sid.organizations.org_id;

但是，在我的python代码中，使用cx_Oracle，使用以下代码（即相同的查询）：

def get_oracle( user, password, tns='TEST' ):
    db = cx_Oracle.connect( user, password, tns )
    cursor = db.cursor()
    return cursor

db = get_oracle( 'me', 'my_pass' )
db.execute("""
select
  persons.person.key AS id,
  persons.person.lname as lastname,
  persons.person.fname as firstname,
  sid.organizations.org_code as org,
  sid.organizations.division_code as division,
  sid.organizations.directorate_code as directorate,
  persons.person.status as status
from
   persons.person,
   sid.organizations
where
   persons.person.dept_id=sid.organizations.org_id;
""")
for r in db:
    pass

结果出现以下错误：

cx_Oracle.DatabaseError: ORA-00911: invalid character

我很确定我的连接没问题，因为其他查询工作正常。

回答我自己的问题，这是一个在查询结尾处带有分号的愚蠢错字！
