python執行sql文件

㈠ python如何操作sql語句

這里有個比較清楚的解答：

但是你的是一個文本的話，就要稍微改一下咯

如果改成cx_Oracle的話，就是這樣的：

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;' #注意這里要改
sql = open('a.sql','r').read() #改成從文件讀取

#接下來就訪問資料庫了
handleDB = handleDataBase(user,passwd,server,sql)
handleDB.selectDB()
handleDB.closeDB()
