准备工作。需要安装pymssql 。。具体怎么安装请自行百度。教程很多。最简单的就是pip install myssql 但是可能会出现版本不兼容的问题。导致导入后不能improt。也可能导致打包的时候出错。
需要三个文件。
1.解析配置文件,连接数据库
# -*- coding: utf-8 -*- __author__ = ‘hero‘ import pymssql import xml.dom.minidom import os import sys curPath = os.path.abspath(os.path.dirname(__file__)) rootPath = os.path.split(curPath)[0] sys.path.append(rootPath) class ExchangeData(object): global CONFIGTYPE_RETEST global CONFIGTYPE_PING global CONFIGTYPE_AGETEST global CONFIGTYPE_IPX CONFIGTYPE_RETEST = ‘RETEST‘ CONFIGTYPE_PING = ‘PING‘ CONFIGTYPE_AGETEST = ‘AGETEST‘ CONFIGTYPE_IPX = ‘IPX‘ ###加载数据库连接数据 def loadDBConfig(self,dbType): xmlDoc = xml.dom.minidom.parse(os.getcwd() +‘\\conf\\/DBConfig.xml‘#此处路径为配置文件的路径 root = xmlDoc.documentElement sql_element = root.getElementsByTagName(dbType)[0] return sql_element def __exchangeDataByDBConnection(self): sqlInfo = self.loadDBConfig(‘MSSQL‘) db_host = sqlInfo.getElementsByTagName(‘HOST‘)[0].firstChild.data db_database = sqlInfo.getElementsByTagName(‘DATABASE‘)[0].firstChild.data db_user = sqlInfo.getElementsByTagName(‘USERNAME‘)[0].firstChild.data db_pwd = sqlInfo.getElementsByTagName(‘PASSWORD‘)[0].firstChild.data conn = pymssql.connect(user=db_user,password=db_pwd,database=db_database,host=db_host) conn.autocommit(True) return conn ###读取数据### def getDataBySql(self,sqlStr): try: conn = self.__exchangeDataByDBConnection() if not conn: raise(NameError,‘数据库连接失败‘) else: cur = conn.cursor() cur.execute(sqlStr) resList = cur.fetchall() conn.close() return resList except Exception,e: print(e) raise(NameError,‘数据库操作失败‘) ###更改数据库### def setDataBySql(self,sqlStr): try: conn = self.__exchangeDataByDBConnection() if not conn: raise(NameError,‘数据库连接失败‘) return False else: cur = conn.cursor() cur.execute(sqlStr) conn.commit() conn.close() return True except Exception,e: print(e) raise(NameError,‘数据库操作失败‘) return False if __name__ == ‘__main__‘: pn = ‘BYAUX-CTN0003‘ sqlStr = "select * from producttype where productNo = ‘"+pn+"‘" edata = ExchangeData() resList = edata.getDataBySql(sqlStr=sqlStr) for dataRow in resList: print(dataRow[0])
2.进行增删改查操作,文件
1 #coding=gbk 2 3 from exchangeData import * 4 import time 5 6 ###数据库相关操作 7 class DataBaseOP(object): 8 ###根据用户名密码,验证用户权限返回值不同,权限不同### 9 def loginApTester(self,username,password): 10 loginSql = ‘SELECT rid FROM bdcomemployee WHERE bdcomLoginName = \‘‘+username+‘\‘ AND bdcomPassword = \‘‘+password+‘\‘‘ 11 loginSql = self.dbTrim(loginSql) 12 eData = ExchangeData() 13 dataRows = eData.getDataBySql(loginSql) 14 if len(dataRows)==0 or dataRows[0] is None: 15 return 0 16 elif dataRows[0][0]==17: 17 return 2 18 else: 19 return 1 20 98 127 ###修改密码### 128 def resetDBPwd(self,userName,oldPwd,newPwd): 129 igStatus = self.loginApTester(userName,oldPwd) 130 if igStatus>0: 131 setSql = ‘UPDATE bdcomemployee SET bdcomPassword = \‘‘+newPwd+‘\‘ WHERE bdcomLoginName = \‘‘+userName+‘\‘ AND bdcomPassword = \‘‘+oldPwd+‘\‘‘ 132 self.dbTrim(setSql) 133 eData = ExchangeData() 134 return eData.setDataBySql(setSql) 135 else: 136 return False; 137 138 139 155 169 170 def dbTrim(self,trimStr): 171 return str(trimStr).replace(‘\t‘,‘‘).replace(‘\n‘,‘‘).replace(‘\r‘,‘‘) 172 173 if __name__ == ‘__main__‘: 174 dbop = DataBaseOP() 175 dbop.loginApTester(‘liuke_ap‘,‘liuke‘)
3.配置文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <JDBC> 3 <MSSQL> 4 <HOST>192.168.1.1</HOST> 5 <DATABASE>abcd</DATABASE> 6 <USERNAME>root</USERNAME> 7 <PASSWORD>root</PASSWORD> 8 </MSSQL> 9 </JDBC>
