这里有个比较清楚的解答：

但是你的是一个文本的话，就要稍微改一下咯
如果改成cx_Oracle的话，就是这样的：
import
sys
import
cx_Oracle
import
os
class
handleDataBase:
def
__init__(self,user,passwd,server,sql):
self.user=user
self.passwd=passwd
self.server=server
self.sql=sql
self.conn
=
cx_Oracle.connect("%s/%s@%s"%(self.user,self.passwd,self.server))
def
selectDB(self):
cursor
=
self.conn.cursor()
cursor.execute("select
count(1)
from
search_item_08")
ret
=
cursor.fetchall()
cursor.close()
print
ret
return
ret
def
closeDB(self):
self.conn.close()
if
__name__
==
"__main__":
if
len(sys.argv)
<
4:
print
"Need
Arguments:
user
passwd
server"
sys.exit(1)
user=sys.argv[1]
passwd=sys.argv[2]
server=sys.argv[3]
#sql='select
count(1)
from
search_item_08;'
#注意这里要改
sql
=
open('a.sql','r').read()
#改成从文件读取
#接下来就访问数据库了
handleDB
=
handleDataBase(user,passwd,server,sql)
handleDB.selectDB()
handleDB.closeDB()
