> # Mapping Data Types

> See "Data Types and Isolation Levels" for information on the way the underlying data provider's data types map to the standard OLE DB data types. IColumns::GetColumnInfo and ICommandWithParameters::GetParameterInfo are used to report OLE DB data types.

> NOTE: Always use four-digit years for conversions from variant types to date/time types. Using two-digit years is not supported and will result in undefined behavior.
