Remarks
The DbEnumerator class is implemented by a .NET Framework data provider to provide data binding support.
By design, the DbEnumerator object is intended for use with only one resultset. For example, if you execute a batch statement containing two SQL SELECT statements that return different schemas, the second statement might not retun the entire schema. To avoid this situation, obtain a DbEnumerator for each resultset, and then call the NextResult
method of a .NET Framework data provider DataReader object.
