I have a dataset result from a query that I am querying to get counts for a webpage.  I am getting an error referencing the ds.  What is the proper way to reference a ds from a query?

here is my code:

SqlDataAdapter da = new SqlDataAdapter(strSQL,con);
da.Fill(ds,"FlagCnts"); // Flag counts of Surveys completed
                              
// count of total flags for records for Surveys completed  by form
strSQL = "SELECT Form, Sum(A_Flag) AS SumOfA_Flag, Sum(L_Flag) AS SumOfL_Flag, Sum(Q_Flag) AS SumOfQ_Flag, Sum(W_Flag) AS SumOfW_Flag, Sum(O_Flag) AS SumOfO_Flag, Sum(D_Flag) AS SumOfD_Flag FROM FlagCnts GROUP BY  Form;";

da = new SqlDataAdapter(strSQL, con);
da.Fill(ds, "TotalFlaggedRecs");

Another way is to just use DataView to filter data from your DataSet

Hi,

I'd say you could combine both queries in just one, so you wont need to access the results from the first query within a second one.
Can you post here the actual SQL you are running the first time?

I was already doing this to a pont.  I was trying to set up another dataset where I did not need to.  Thanks for the assistance.
