Native driver for DB2 does not understand WITH statement, but ODBC socket does.
For example query:
with query (id) as (values (nullid.nextid('sessions.id'))) select id from query
is considered as erroneous in by DB2 native driver
and considered as valid by ODBC socket driver.

What should be tuned to allow DB2 native driver to understand WITH-statement
(table hint SQL statement)?
