Steven Hawkins commented on TEIID-2779:
---------------------------------------
I'm thinking of something like:
with a as (select * from (select ... fetch first 10 rows only) as x) ....
such that you could keep the CTE. The DB2 8 instances (not Z/OS) I have access to is happy with a CTE with a limit, so I'm not directly able to see what doesn't work.
