If you want to identify a particular member within a file, use the following SQL command:
CREATE ALIAS your-alias FOR your-library/your-file (your-member)
When you issue a command such as the following select statement...
SELECT * FROM your-alias.
...the data is read from the specific member associated with the alias. Multiple members are not allowed for tables created through SQL, but if you are accessing data in non-SQL tables, this works fine.
The alias is actually implemented as a Distributed Data Management (DDM) file that points at the *LOCAL database.
