要用python链接到数据库,又不想写太多代码。想到了django,就偷懒了下。用django.db直连。
django版本:1.6.5 (1.5以后可以用以下代码)
#coding=utf-8
__author__ = 'tommy.yu' from django.db import connection
from django.conf import settings
"""
settings.configure(
ENGINE ='django.db.backends.postgresql_psycopg2',
NAME='django',
USER='django',
PASSWORD='1',
HOST='localhost',
PORT='5432',
)
""" settings.configure(
DATABASES = { 'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'YOUR_DB_NAME',
'USER': 'YOUR_USER',
'PASSWORD': 'YOUR_PASS',
'HOST': 'YOUR_SERVER_IP',
'PORT': 'YOUR_SERVER_PART',
}, },
TIME_ZONE = 'Hongkong'
) class cursor(object):
def __init__(self):
self.cr = connection.cursor() def query(self,sql):
self.cr.execute(sql)
res = self.cr.fetchall()
self.cr.close()
return res def un_query(self,sql):
return self.cr.execute(sql)
"""
#测试代码
cr =cursor()
res = cr.query('select tablename from pg_tables')
print(res)
"""
1.5 以前如此配置
settings.configure(
ENGINE ='django.db.backends.postgresql_psycopg2',
NAME='django',
USER='django',
PASSWORD='***',
HOST='localhost',
PORT='5432',
)
