Remarks

The SelectedData class represents the result of batch select queries made to a data store. For instance, it is retrieved by the IDataStore.SelectData method, SQL queries, or stored procedures.

The result of select operations is specified by the SelectedData.ResultSet array. The number of elements in the array matches the number of select statements. To learn more, refer to How to: Access Data in SQL Query Results.
