GetColumnGUID Method
В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.
The GetColumnGUID method returns a void pointer to the memory that implements storage of a binary data type.

The Row and Column Parameters are 1-based in Microsoft Visual Basic applications, and are zero-based in C++ applications.
