Hi,
I remembered something when playing wiht BLOB. It looks that the select

work well with BLOB. It always add or modify the BLOB a little bit.
Later I found out that
the client programming interfaces, perl,C++ etc tend to do well on BLOB

Can I just ask a quick question about this one, mainly about the Group By
