Programming Considerations
The following programming considerations apply:
Teradata Database does not return parameter information. Therefore, OLE DB Provider
for Teradata does not support GetParameterInfo unless the consumer describes the parameter
via SetParameterInfo.
Always set the information for a parameter via SetParameterInfo before calling GetParameterInfo.
If the consumer has not called SetParameterInfo, then GetParameterInfo returns the
DB_E_PARAMUNAVAILABLE error code.
