JavaScript使用ActiveXObject访问Access和SQL Server数据库

JS操作 Access 数据库

<SCRIPT LANGUAGE="JavaScript">  

<!--  

var filePath = location.href.substring(0, location.href.indexOf("实例197.连接Access数据库.html"));    //以当前页面文件为基础，找到文件所在的绝对路径  

var path = filePath + "197.mdb";  

path = path.substring(8);            

var objdbConn = new ActiveXObject("ADODB.Connection");         

var strdsn = "driver={Microsoft Access Driver (*.mdb)};dbq=" + path;     

objdbConn.Open(strdsn);                       

document.write("连接ACCESS数据库成功!<br>");  

objdbConn.Close();                          

//-->  

</SCRIPT> 

连接SQL Server数据库

<SCRIPT LANGUAGE="JavaScript">  

<!--  

var objdbConn = new ActiveXObject("ADODB.Connection");    

var strdsn = "Driver={SQL Server};SERVER=(local);UID=sa;PWD=111111;DATABASE=hljdatabase";    

objdbConn.Open(strdsn);       

document.write("数据库连接成功<br>");      

objdbConn.Close();                     

//-->  

</SCRIPT> 

查询数据库实例

<SCRIPT LANGUAGE="JavaScript">  

<!--  

var objdbConn = new ActiveXObject("ADODB.Connection");    

var strdsn = "Driver={SQL Server};SERVER=(local);UID=sa;PWD=111111;DATABASE=hljdatabase";      // 需要修改自己的服务器地址,用户名,密码  

objdbConn.Open(strdsn);       

var objrs = objdbConn.Execute("SELECT * FROM 表 where 关联=0");                  // 输入本地的表  

var fdCount = objrs.Fields.Count - 1;           

if (!objrs.EOF){                                 

  document.write("<table border=1><tr>");     

  for (var i=0; i <= fdCount; i++)                  

      document.write("<td><b>" + objrs.Fields(i).Name + "</b></td>");  

  document.write("</tr>");  

  

  while (!objrs.EOF){                     

    document.write("<tr>");               

    for (i=0; i <= fdCount; i++)  

       document.write("<td valign='top'>" + objrs.Fields(i).Value + "</td>");  

    document.write("</tr>");  

    objrs.moveNext();                   

  }  

  document.write("</table>");   

}  

else   

  document.write("数据库内没有记录!<br>");  

objrs.Close();                           

objdbConn.Close();

操作数据库实例

<SCRIPT LANGUAGE="JavaScript">  

<!--

var strdsn = "Driver={SQL Server};SERVER=(local);UID=sa;PWD=111111;DATABASE=hljdatabase";   // 需要修改自己的服务器地址,用户名,密码

document.write("更新数据成功!<br>");  

objdbConn.Close();
