Sergey,
I haven't used this approach for large files. Just did some quick testing and it seems that the limit is about 8MB. After that the function StrToHex() returns a "String too long" error.

For larger files, Vlad's workaround seems to work fine.

Unfortunately, I don't know of any other way to retrieve binary data from SQL Server other than the hack with the General/Memo field described in Vlad's article.
