python 连接mssql数据库

1.目标数据sql2008 R2 ComPrject=>TestModel

 

2.安装python 连接mssql 模块

运行 pip install pymssql-2.2.0.dev0-cp36-cp36m-win_amd64.whl

运行完毕 查看是否成功 pip -m  list

3.编写python 代码

import time
import pymssql
#import decimal

class MSSQL:
    def __init__(self,host,user,pwd,db):
        self.host=host
        self.user=user
        self.pwd=pwd
        self.db=db
    def GetConnect(self):
        if not self.db:
            raise(NameError,'没有目标数据库')
        self.connect=pymssql.connect(host=self.host,user=self.user,password=self.pwd,database=self.db,charset='utf8')
        cur=self.connect.cursor()
        if not cur:
            raise(NameError,'数据库访问失败')
        else:
            return cur
    def ExecSql(self,sql):
         cur=self.GetConnect()
         cur.execute(sql)
         self.connect.commit()
         self.connect.close()
    def ExecQuery(self,sql):
        cur=self.GetConnect()
        cur.execute(sql)
        resList = cur.fetchall()
        self.connect.close()
        return resList   
def main():
    ms = MSSQL(host="192.168.0.108", user="sa", pwd="sa", db="ComPrject")
    resList = ms.ExecQuery("select *from TestModel")
    print(resList)

if __name__ == '__main__':
    main()
    input("执行完成:")

4.运行效果

备注：如果读取中文出现乱码，需要修改varchar=>nvarchar
