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

 1 import time
 2 import pymssql
 3 #import decimal
 4 
 5 class MSSQL:
 6     def __init__(self,host,user,pwd,db):
 7         self.host=host
 8         self.user=user
 9         self.pwd=pwd
10         self.db=db
11     def GetConnect(self):
12         if not self.db:
13             raise(NameError,'没有目标数据库')
14         self.connect=pymssql.connect(host=self.host,user=self.user,password=self.pwd,database=self.db,charset='utf8')
15         cur=self.connect.cursor()
16         if not cur:
17             raise(NameError,'数据库访问失败')
18         else:
19             return cur
20     def ExecSql(self,sql):
21          cur=self.GetConnect()
22          cur.execute(sql)
23          self.connect.commit()
24          self.connect.close()
25     def ExecQuery(self,sql):
26         cur=self.GetConnect()
27         cur.execute(sql)
28         resList = cur.fetchall()
29         self.connect.close()
30         return resList   
31 def main():
32     ms = MSSQL(host="192.168.0.108", user="sa", pwd="sa", db="ComPrject")
33     resList = ms.ExecQuery("select *from TestModel")
34     print(resList)
35 
36 if __name__ == '__main__':
37     main()
38     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
