python 和 c# 连接数据库 (Access)

模块pypyodbc 1.3.3下载：   https://pypi.python.org/pypi/pypyodbc/

安装：解压文件找到pypyodbc.py复制到python安装目录Lib文件夹下即可

import pypyodbc 
             
pypyodbc.win_create_mdb('D:\database.mdb')

connection_string = 'Driver={Microsoft Access Driver (*.mdb)};DBQ=D:\database.mdb'

connection = pypyodbc.connect(connection_string)

SQL = 'CREATE TABLE saleout (id COUNTER PRIMARY KEY,product_name VARCHAR(25));'

connection.cursor().execute(SQL).commit()

 c# 连接数据库 (Access) 

1、数据库准备

2、新建一个控制台应用程序

3、直接运行可以使用

4、可以使用一个帮助类来调用

使用注释的部分即可。

5、所有的代码

//Program.cs

using System.Collections.Generic;

            string sqlString = "select * from  ChinaNANO2007 where id=207";
            OleDbConnection conn = new OleDbConnection(connstring);
            OleDbCommand cmd = new OleDbCommand(sqlString, conn);
            conn.Open();
