But, if the documents are coming in from somewhere, they will not be in character constants will they? I mean, your authors are not going to write:
insert into table values ( 'this is my document, it''s a very good one' );
They are going to write the document and then you will load it using a 3/4gl right?
Bind variables support much more then 2000 characters (4000 in o8). For example, using PL/SQL we can do 32k at a time as such:
drop table demo;
create table demo ( x long );
declare
myvar long default '
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx(lots of stuff here)......
insert into demo values ( myvar );
dbms_output.put_line( length( myvar ) );
end;
The pl/sql variable can be initialized to upto 32k of static text. It can then be inserted into the table (it is a bind variable, not a constant at that point).
For example, I just ran it and it showed me:
Table dropped.
Table created.
24726
PL/SQL procedure successfully completed.
So, that put a 24,726 character string into the table...
For larger then 32k, you need a 3/4gl such as C, Forms, VB, etc.
