Hi Jeff,

CTE syntax will let you create multiple objects, but not nested ones.

WITH a AS (vlist1...)
  SELECT ...
b AS (vlist2...)
  SELECT ...

Open in new window

And of course the defined objects can reference other defined objects in the CTE.

Yep, you only need "with" once, after that each cte is separated by a comma.
This is as specified in the SQL Standards by the way, not specific to DB2

no points please

Awesome thank you.  Having trouble getting it to work in DB2 so got around it by just using code and not creating calculated values.

If you'll post the code, I'm sure we can show you how to write it as a CTE.
