Thanks Michael,
Yes you are 100% right. And I think Mark was probably making the same
point. The attribute list must stay!

As a personal style or standard, you might choose not to override column
names in the attribute list – but if you are extracting DDL for an existing
view then you are at the mercy of whoever wrote that view.
i.e. if the original author wrote
CREATE OR REPLACE VIEW V (DOG) as SELECT DUMMY AS CAT FROM DUAL;
Then you definitely need the column specification to correctly re-create
the view.

Hi Mark
I am of the opinion that views should always have an attribute listsince I have encountered views where the view column name does not match up
to the select list column names.
I have a different opinion on this. If I want the column names to differ I
use an alias in the select statement. The problem I see with the attribute
list is that it can get out of sync with the attributes in the select list.
I just dont see any good reason to use the attribute list.
Nor should a new column added to a table automatically appear in anyviews defined on the table. The sensitivity of the column data has to be
considered in relation to the purpose and audience of each view that
references the table.
Agreed. I didn't say anything about automatically adding columns to views.
When the view is updated you can easily generate the view code from theRDBMS Dictionary or using DBMS_METADATA.
Yes thanks but I was just trying to figure out if SQL Developer Database
export could do this for me.
