If you need to automate the process you could use DSPFD MBRLIST to an outfile
Have an SQL-RPGLE read each member and
1. Issue an SQL to Create the Alias
2. Add to a string for the Create View as ‘ the additonal …
‘ union
select * from ‘ + aliasName
Once all the members have been processed run the string as a dynamic SQL .. once the view is created you can use it like a file

not elegant, but you could create a UNION statement over multiple ALIASed members

create alias s1...
create alias s2...
...
create alias sn...

select * from s1
union
select * from s2
union
...
select * from sn

How can you use “create alias” to return all members of the primary file?

AFAIK, unless it’s a partitioned table, you can’t.

SQL doesn’t handle members. If you need SQL to process all rows in a table, the data shouldn’t be put into multiple members. But if you are already stuck with members. you can create a logical file that includes all members if it’s a keyed logical.

Since you probably have been stuck with multiple members, that might be your only choice for creating a permanent object. And since it can be done with a simple logical file, there doesn’t seem to be much reason to allow an ALIAS to do it.

If anybody knows an alternative, it’ll probably get posted here.
