Webservice question

[steve_rm]

Hello,

I am trying to create a webservice that will enable me to retrieve rows from a database in sql. I would like the service to return the datatable filled with the records. So that the consumer can display in a datagrid. But l am not sure if l am going about it correctly.

This is my code below.

[WebMethod (Description="This will get retrieve customers' orders")]
        public DataTable RetrieveOrders()
        {
            SqlConnection cnn = new SqlConnection("Server = Steves-pc; Database = northwind; Integrated Security = yes");
            cnn.Open();
            SqlDataAdapter da = new SqlDataAdapter();
            SqlCommand cmd = new SqlCommand();
            DataTable dt = new DataTable("Orders");
        
            string getOrders = "SELECT OrderID,CustomerID,ShipName,ShipCountry FROM Orders";
            cmd = cnn.CreateCommand();
            cmd.CommandType = CommandType.Text;
            cmd.CommandText = getOrders;
            da.SelectCommand = cmd;
 
            dt.Clear();
            da.Fill(dt);
 
            cnn.Close();
 
            return dt;              
        }

Many thanks in advance,

Steve

Are you having any particular troubles? I do this, but instead I use a DataSet, even for just one table. Now that I think about it, I'm not really sure why, probably because all the examples were like that.
