What is the sql connection string I need to use to access localhost\SQLEXPRESS with Windows Authentication or SQL Authentication?

Question

\'ve installed SQL Express on my PC hoping to do some practice creating tables and then modifying them. I coded a webpage in Visual Studio to, basically, SELECT * from a tab

Answer 1

If you are placing your data connection string in a web.config file you specify your connection like below:

<connectionStrings>
<add name="NorthwindConnString" 
     connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True" 
     providerName="System.Data.SqlClient"/>
</connectionStrings>

but if you are hard coding within a c# based website you have to escape the '\' back slashes:

"Data Source=.\\\\SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True"

Even Scott Hanselman can forget this...

Answer 2

Try using Windows authentication:

Data Source=localhost\SQLEXPRESS;Initial Catalog=test;Integrated Security=SSPI;

Answer 3

Try like this:

string connectionString = "Data Source=.\\SQLEXPRESS;Initial Catalog=test;User Id=x309;Password=abcd;";

Also make sure you have enabled SQL authentication.

public partial class _Default : System.Web.UI.Page
{
    SqlConnection con = new SqlConnection("Data Source=SHANU-PC\SQLEXPRESS;Initial Catalog=Anusha;Integrated Security=True");
    protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
        {

        con.Open();
        SqlCommand cmd=new SqlCommand("select * from tbl_state",con);

        SqlDataAdapter da=new SqlDataAdapter(cmd);

        DataTable dt=new DataTable();
        da.Fill(dt);
            DropDownList1.DataSource = dt;
            DropDownList1.DataTextField = "sname";
            DropDownList1.DataValueField = "sid";
            DropDownList1.DataBind();

        con.Close();
        }
