Re: SQL views over multi member physical file

Given that, one alternative might be to write a User Defined Table
function with an RPG program behind it.

Select t.*
from mytable('MEMBER_1',500) as t

would return the last 500 rows of MEMBER_1.

For efficiency, the RPG could start at the end of the member and
read backwards.

You would have to train your internet group in this syntax, but hey,
aren't they SQL geeks?

I doubt if you could put the above in a view, given that you are in
essence passing two parameters <<SNIP>>

Irrespective of the sensibility in so doing... Such a UDTF could easily be encapsulated in a VIEW:

create MyTable_Mbr01_Last500 as
select t.*
from TABLE ( mytable('MEMBER_1', 500) ) as T
