SQL - CTE - Insert

["Michael Ryan" <michaelrtr@xxxxxxxxx>]

Well, looking at Charles example of a CTE, I thought I would try this:

with stuff as (Select xmmail, xmsmn1, min(xmcdte) From posmstp
Where xmmail <> ' ' Group by xmmail, xmsmn1) INSERT INTO
NEWSYS/EMLslsP (Esemp#, Esemail, esactive, escred) from (select * from
stuff)

But I get this error:
Keyword INSERT not expected. Valid tokens: ( SELECT.

This works fine:

with stuff as (Select xmmail, xmsmn1, min(xmcdte)
              From posmstp
              Where xmmail <> ' '
              Group by xmmail, xmsmn1)
select xmmail, xmsmn1 from stuff

Does an Insert not work with a CTE like this?

Also, prompting isn't supported when I use a CTE - is that just the way it
is?
