Hi Alan,
You cannot create a view for built over a file member neither a view over an
alias that points to a file member.
But it is possible to access members from within an UDTF and UDTFs can be
specified within the FROM clause of an SELECT statement and used like any
table or view:
Example:
Assumed an alias that points to a member already exist, you can create the
following UDTF.
CREATE FUNCTION YourSchema/YourUDTF()
RETURNS TABLE( Col1 Char(10), Col2 Dec(11, 2), .... ColN DataType(Length) )
LANGUAGE SQL
MODIFIES SQL DATA
Return Select Col1, Col2, ... ColN from YourAlias;
After the UDTF is generated it can be accessed as follows:
Select *
From TABLE(YourUDTF()) x;
If the alias does not exist, the creation can be included in the UDTF source
code.
For more information about UDTFs (you may refer to the following article:

Betreff: SQL views over multi member physical file
Hi everyone
Before I forget - we are on V5r4
We have a multi-member file (presently 16 members - but can increase) There
is a need is to create individual SQL views over each of these members I
understand/know about alias's, but from what I have
googled/yahoo'ed/searched, it looks like I cannot create a view over an
alias Question 1 - is this in fact true?
Question 2 - In creating the alias (or view for that matter), is there a way
to limit the alias (or view for that matter) to the LAST n records?
As always - any and all responses gratefully accepted
Alan Shore
