Question

conn = new SqlConnection(@"Data Source=ASHISH-PC\SQLEXPRESS; initial catalog=bank; integrated security=true");
ada = new SqlDataAdapter("select total_amount from debit_account where account_no=12", conn);
ds = new DataSet();

ada.Fill(ds);

Now, I want to print value of the dataset… how? Please help me.

Answer 1

I think, in this case, you’d be better off (performance-wise) to use a SqlCommand instead of the adapter and dataset, and invoke the ExecuteScalar method.

See http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.executescalar.aspx

If you must use the data set, however, ds.Tables[0].Rows[0]["total_amount"] should retrieve your value. You will probably need to type cast the value, though.
