Hi team

I was just asking that If table ITEM3 has all the columns then why we need
to have a join ?? even we put a sorting very easily.

*** Any way  I have a very intersting question to all of you. I want to
fetch more that 70,000 BLOB from different customer servers. the issue is
there are some BOLB files with common names on all servers. So I want merge
these files into a single BLOB during  fetching data. I am able to fetch
the  BLOB data from all cust servers but unfortunatelly it overwrite
previous file.

So pls provide any simple query format for the same, assuming two table tab1
& tab 2.
