  How can i bind variables to database in sql server?

  May 30, 2013 05:44 AM|akshitbansal|LINK

   I have designed a page using inline programming that is using strbuild.append.

  I have declared strings which i want to be fetched from the database.

  Eg. String address ="";

  strbuild.append("address is"+address);

  i want address from the database.

  Please tell me about it including establishing the connection as well

  hi,

  you can try such as the following code

  SqlConnection conn = new SqlConnection(GetConnectionString());
                  conn.Open();
                  string qury = "select Emp_id,Password from loginuser where (name=@Emp_id) and (Password=@Password)";
                  SqlCommand cmd = new SqlCommand(qury, conn);
                  cmd.Parameters.AddWithValue("@Emp_id", name);
                  cmd.Parameters.AddWithValue("@Password", password);
                  DataTable dt = new DataTable();
                  SqlDataAdapter da = new SqlDataAdapter(cmd);
                  da.Fill(dt);
                  if (dt.Rows.Count >= 0)
                  {
                      string address = dt.Rows[0]["address"].ToString();
                  }

  you may attention following points.

  1).GetConnectionString() that return your database connection;

  2).qury  is your sqlcommand and you can user yours.

  Hope it will help you
