True, but I think that's just a historical artifact. If you look at the
SQL spec, INSERT ... VALUES and INSERT ... SELECT are not distinct
constructs: they fall out of the fact that VALUES and SELECT are allowed
<insert statement> ::=
INSERT INTO <table name>
<insert columns and source>
<insert columns and source> ::=
[ <left paren> <insert column list> <right paren> ]
| DEFAULT VALUES
<insert column list> ::= <column name list>
and when you trace down <query expression> you find the SELECT
and VALUES options entering at exactly the same place ...
I'd like to see us refactor the docs as necessary to reflect that idea.
Peter is right that this needs some discussion in syntax.sgml as well as
in the reference pages --- but I'm still not very clear on how the
presentation should go.
