-  This rule accepts just about anything. The reason is that we have

-  subselect_start. This forces bison to take a decision which rules to
-  reduce by long before it has seen any tokens. This approach ties us
-  to a very limited class of parseable languages, and unfortunately
-  SQL is not one of them. The chosen 'solution' was this rule, which
-  produces just about anything, even complete bogus statements, for
-  instance ( table UNION SELECT 1 ).
-  Fortunately, we know that the semantic value returned by
-  select_derived is NULL if it contained a derived table, and a pointer to
-  the base table's TABLE_LIST if it was a base table. So in the rule
-  regarding union's, we throw a parse error manually and pretend it
-  was bison that did it.
- 
-  Also worth noting is that this rule concerns query expressions in
-  the from clause only. Top level select statements and other types of
-  subqueries have their own union rules.
