The library list only works when using the system naming convention.
SQL_NAMING
Specifies that tables are qualified by the collection name in the form:
collection.table
where collection is the name of the collection and table is the table name. The default qualifier is the user ID running the process that executes the SQL statement and is used when the table name is not explicitly qualified and the default collection name is not specified.SYSTEM_NAMING
Specifies that files are qualified by library name in the form:
library / file
where library is the name of the library and file is the table name. The default search path is the library list (*LIBL) for the unqualified table name, if the table name (file) is not explicitly qualified and a default collection name (library) is not specified.
