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
