Thanks, Peter
I didn't immediately think of the fact that I'd avoid repeating the code as well with a view. In my case it is just a cursor that is set up once in the program. But in testing with a view, and then having to rewrite the code without it, certainly makes the code messy. As it's only once maybe it's not important.
The reason for not allowing permanent views yet is simply because the change management system needs to be able to take views into account.
But I thought nothing prevents me from creating a temporary view and tucking this creation away in the program initialization procedure. I do believe that the creation will cost me nothing.
Although, as you say, I've been wrong before, also.
So many, many times before. What was that song called?

Objet : RE: SQL View
David,
is it a management decision not to allow views, or is there a technical reason behind it?
AFAIK, a view is a way to only show selected fields from a file/table, or a simple way to access data that is in different files/tables, or a way to get calculated fields easily, without having to re-type the calculations in SQL or your program.
Of course, I've been wrong before ;-)

Subject: SQL View
Hi,
Unfortunately we are not ready to have views on our system. In a test,
I created a view on 3 PF, called it, for example, articles, and then
in my program was able to run "Select info from articles".
As I cannot keep the view, my final select statement will have to be a
lot more complex.
I'd like to know, does a view do anything more than simplify an
otherwise complex request? Would it be reasonable in my case to create
the view at the start of my program and then drop it at the end?
Thanks
