Well that is really a question about ADO.NET's *Command family of

ExecuteScalar - executes your query and returns just value for the
first-column from the first row returned. It is good for things like
"SELECT Max(Amount) FROM FinancialData WHERE ...".

ExecuteReader - Returns a DataReader that you can use to iterate over
the returned row, getting values for any columns returned.

Hope it helps,
