Remarks
Item returns a System.Object that is the root of all types. It is used to retrieve any Teradata data type. The .NET Data Provider for Teradata maps the Teradata data types to .NET Framework types and returns an Object reference.

Item is the most flexible field retrieval method, but is also the slowest field retrieval method. It is strongly recommended to use the other strongly typed field retrieval methods (for example, GetInt32).

This method does not throw an exception for null database fields. It returns an instance of DBNull.
