Programming Considerations - OLE DB Provider for Teradata

Programming Considerations

OLE DB Provider for Teradata supports the following DBCOLUMNFLAGS:

DBCOLUMNFLAGS_ISFIXEDLENGTH

DBCOLUMNFLAGS_ISNULLABLE

DBCOLUMNFLAGS_MAYBENULL

DBCOLUMNFLAGS_WRITEUNKNOWN

For those flags that OLE DB Provider for Teradata does not support, the bit assigned to the unsupported flags in the dwFlags element of the DBCOLUMNINFO structure is always set to 0.

For more information, refer to the Microsoft Developer’s Network (MSDN) documentation on IColumnsInfo::GetColumnInfo.
