I wonder how to do by sql?
Why LONG RAW?
What is the business case?
In which version of Oracle?

The real field name is YFBZYJ in table T1 and T2.
I use Oracle 9i.

Some one design the database, the field YFBZYJ is
used for client to fill opinion which maybe
100 characters, or maybe 5,000 characters long.
So the designer change the origin field type
from varchar2(4000) to Long Raw.

Yes, Blob or Clob will be better.But web developers use
a interface to operate database. This interface can only
deal with long raw.

I am responsible to dealing with data. Now I should
move data to new table with the long raw field.

Either the web developers are crazy or you have misunderstood
what they are saying. LONG RAW is binary ... not text. There is
no way an end user is going to use it to store comments.

Check out the Data Types page in Morgan's Library at www.psoug.org
to view the various data types and what their definitions.

In my experience there is no interface that does not allow CLOB
and you should not accept anything except CLOB without a far better
understanding of why anyone is claiming it can not be done. That
said ... what product are they using (include version number).

It just occured to me that some Oracle products, Forms for example,
still use LONG to indicate LONG or CLOB. Hopefully this misuse of the
name will be fixed in Forms 11g.

thank you very much.

Can you give me some suggestions about this scenario:

user will input many characters, maybe 1,000,
maybe 10,000. How to store these characters into database
except using attachment ?
