how to get data in sql 2005 using javascript in asp.net

YOu can use raw-ajax function to get value from server
which uses XML Object
i.e.
 

 

 function getValueByAjax(url,getxml)
    {
        
        
        var req;
        try {
         req = new XMLHttpRequest();  //e.g. Firefox
         } catch(err1) {
           try {
           req = new ActiveXObject('Msxml2.XMLHTTP'); // some versions IE 
           } catch (err2) {
             try {
             req = new ActiveXObject("Microsoft.XMLHTTP"); // some versions IE 
             } catch (err3) {
              req = false;
             }
           }
         }
   
        req.open("GET", url  ,false);
      
        req.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
        
        req.send();
        var item ;
        if(req.readyState == 4) 
        {   
           if(req.status == 200) 
           {
              item = req.responseText;
              if(getxml==1)
              {
                 item = req.responseXML;
              }
           }
        }
      
         return item;
    }
    
 

and do process from server side
 
and manupulate returned string as you want...

get data in sql 2005 using javascript
Database will be on server side. So you need to use techniques that will allow you to talk to server from JavaScript.
 
There are few ways to interact with server side through client side(Javascript):
1. XMLHttpRequest[^]
2. Callback[^]
3. WebService call[^]
4. PageMethod[^]
 
Try the one that suits you.
