As Mark stated, use 'SET LONG'.
However, generating DDL for views is kind of problematic.
DBMS_METADATA is buggy, and the SQL generated for views is generally
unusable.
The DBA_VIEWS.TEXT column contains the SELECT portion of the view, but in
many
cases the column names will be incorrect.
The options I know of:
1) write some code to correctly generate the views.
this is rather time consuming
2) create schema only exports, and grep the view statements from the file.
Search on 'CREATE OR REPLACE VIEW' and 'CREATE OR REPLACE FORCE VIEW'
If there's an easier way to do this, I would also like to know.
