Re: SQL0203 - Name xxxx is ambiguous, when using JOIN USING

I'm getting SQL0203 - Name MYKEY is ambiguous

I've tried adding parens (in various places), but get the same

Does the following revision to the above query, with parentheses as specified, enable the joined-table specification to use the "JOIN ... USING" syntax for the next table-reference? As I recall, that is the proper\expected syntax.

select mykey, flda, fldb, fldc
from ( tbla
join tblb using (mykey)
) /* end joined-table 1 */
join tblc using (mykey)
/* end joined-table 2; non-parenthetical */
