How to connect to SQL Server database from JavaScript in the browser?

Question

Can anybody give me some sample source code showing how to connect to a SQL Server 2005 database from JavaScript locally? I am learning web programming on my desktop.

Answer 1

Web services

SQL 2005+ supports native WebServices that you could almost use although I wouldn't suggest it, because of security risks you may face. Why did I say almost. Well Javascript is not SOAP native, so it would be a bit more complicated to actually make it. You'd have to send and receive SOAP via XmlHttpRequest. Check google for Javascript SOAP clients.

A perfect working code..

    <script>
    var objConnection = new ActiveXObject("adodb.connection");
    var strConn = "driver={sql server};server=QITBLRQIPL030;database=adventureworks;uid=sa;password=12345";
    objConnection.Open(strConn);
    var rs = new ActiveXObject("ADODB.Recordset");
    var strQuery = "SELECT * FROM  Person.Address";
    rs.Open(strQuery, objConnection);
    rs.MoveFirst();
    while (!rs.EOF) {
        document.write(rs.fields(0) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
        document.write(rs.fields(1) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
        document.write(rs.fields(2) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;    ");
        document.write(rs.fields(3) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;    ");
        document.write(rs.fields(4) + "<br/>");
        rs.movenext();
    }
</script>
