I did get the table function to work but I had to have the x like
this:

SELECT * FROM Table(Qsys2/Users()) x

Guess I should search out table functions to see what that's for.

The same requirement exists for a Nested Table Expression (NTE); i.e. not specific to the use of TABLE().

The syntax requires a correlation-clause for the table-function; as shown in the diagrams, and noted [emphasis mine] within the text:
[http://www.ibm.com/support/knowledgecenter/api/content/ssw_ibm_i_71/db2/rbafztabref.htm]
"_table-reference_

A table-reference specifies an intermediate result table.

...

table-function

|--TABLE--(--function-invocation--)--correlation-clause-----|

...

correlation-clause

.-AS-.
|--+----+--correlation-name--+-----------------------+------|
| .-,-----------. |
| V | |
'-(----column-name-+--)-'

...

Each correlation-name is defined as a designator of the intermediate result table specified by the immediately preceding table-reference. A correlation-name *must be specified* for nested table expressions and *table functions*.
