- Which dataset should you choose?
- DataReader is not DataSetThere is NO DataSet instance created in your first listing. Instead, SqlCommand.ExecuteReader returns an equivalent of forward-only, read-only server-side cursor which allows the client to quickly and efficiently process query results ONE ROW AT A TIME. This is fundamentally different from the purpose and characteristics of disconnected...

- Hydrus DataSet Toolkit (exe)
- Automates Select/Insert/Update/Delete operations in .Net by generating SQL statements on-the-fly based on your strongly-typed DataSet object. Eliminates the need for DataAdapter code, or maintaining SQL statements of any kind. You limit query results via WhereConstraint objects which create the SQL statement predicates. The primary advantage of the Hydrus Software CommandBuilder...
