PyMySQL 是在 Python3.x 版本中用于连接 MySQL 云服务器的一个库,Python2中则使用mysqldb
话不多说,直接上代码来说明用途
#!/user/bin/env python
#coding=utf-8
from pymysql import connect,cursors
from pymysql.err import OperationalError
import os
import configparser as cparser
from builtins import int
from framework.logger import Logger
import time
'''
========读取config.ini文件中mysql配置========
'''
base_dir = str(os.path.dirname(os.path.dirname(file)))
file_path = base_dir + "\config\config.ini"
cf = configUtil(file_path)
host = cf.get("sitmysqlconf", "host")
port = cf.get("sitmysqlconf", 'port')
db = cf.get("sitmysqlconf", 'db_name')
user = cf.get("sitmysqlconf", 'user')
password = cf.get("sitmysqlconf", 'password')
logger = Logger(logger="mysqlUtils").getlog()
'''
===========封装MySQL基本操作=============
'''
class mysqlUtils:
def __init__(self):
'''

'''
try:
self.conn = connect(host=host,
port=int(port),
user=user,
password=password,
db=db,
charset='utf8mb4',
cursorclass=cursors.DictCursor
)
except OperationalError as e:
print (e)
def cursor(self):
'''

self.conn.cursor()
def getDict(self,tableName,systemID,ColumnNameKey,ColumnNameValue):
'''

'''
with self.conn.cursor() as cursor:
cursor.execute("select * from %s WHERE system_id = %s and %s = %s",(tableName,systemID,ColumnNameKey,ColumnNameValue))
Dict = cursor.fetchone()
self.conn.commit()
return Dict
def AttentionLibraryDelete(self,system_id,merchant_id):
'''非正常删除数据,即直接操作数据库删除'''

self.conn.commit()
def addMerchantTOIT(self,merchant_id):
'''把商家关联到XXX行业中'''
#realSQL = "INSERT INTO tableName (system_id, merchant_id, business_id, status, creator_id, create_date, updater_id, update_date) VALUES ('7b6a99f3bce14915863cde5104bdf2c3', %s, '11', 'A', '8', unix_timestamp(now())*1000, '8', unix_timestamp(now())*1000);" % repr(merchant_id)

self.conn.commit()
logger.info('把商家【%s】关联到xxx成功'%merchant_id)
def close(self):

'''
self.conn.close()
