Hi, if I have a stored procedure that when executed will return one row, with three columns, what is the best way to get the data from this. At the mo I have a sqldataadapter filling a dataset, but ho do I get the data from there, I want three vars say v1,v2 and v3 to be populated with the string vals in the row?

Thanks Kieran.

DataAdapter.Fill(yourDataSet, "tablename");

if(yourDataSet.Tables["tablename"].Rows.Count == 1) {
    DataRow dr = yourDataSet.Tables["tablename"].Rows[0];
    //here you can access variables like dr["name"] ...
}

given that you only return 3 values you might want to look at output parameters from your stored procedure.

Even a DataAdapter and DataSet may be a bit overkill. If you're just reading the data and not updating it, a DataReader should do the job.

string col1, col2, col3;
SqlCommand cmd = new SqlCommand("storedProcedure", connectionObject);
cmd.CommandType = CommandType.StoredProcedure;
connectionObject.Open();
SqlDataReader dr = cmd.ExecuteReader();
dr.Read();
col1 = dr.GetString(0);
col2 = dr.GetString(1);
col3 = dr.GetString(2);
dr.Close();
connectionObject.Close();
