Github user DaveBirdsall commented on a diff in the pull request: https://github.com/apache/incubator-trafodion/pull/577#discussion_r70505167 --- Diff: core/sql/parser/sqlparser.y --- @@ -7001,6 +7036,46 @@ rel_subquery_and_as_clause : rel_subquery as_clause $$ = $2; } +with_clause_list : with_clause + { $$ = $1 ; } + + | with_clause_list ',' correlation_name TOK_AS rel_subquery --- End diff -- One way would be: with_clause : WITH with_clause_elements with_clause_elements : with_clause element | with_clause_elements with_clause_element with_clause_element : correlation_name TOK_AS rel_subquery By the way, I notice the way this is coded, the "with_clause" non-terminal is a single correlation_name TOK_AS rel_subquery element. It seems more natural (to me anyway) to think of the with_clause as being everything from the WITH keyword through the entire list of subqueries.
