RE: SQL - CTE - Insert

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

Michael,

Insert will work with, but the syntax is a little strange:

Insert into NEWSYS/EMLslsP (Esemp#, Esemail, esactive, escred)
with stuff as (Select xmmail, xmsmn1, min(xmcdte) From posmstp
Select * from stuff

When you look at the syntax diagrams it makes sense

INSERT INTO table-name (columns)
->Select-statement<-

Select-statements (using CTE's look like)
WITH ctename ->fullselect<-

And the fullselect is of course
SELECT coumns
FROM sometable
WHERE
<snip>


Note that v5r3 supported CTE in an insert statement.

HTH,


Charles Wilt
