Howto Insert Into Table with Select and Order by using fetch first rows only with DB2 - insert

Question

I am using DB2 V7.2 Express-C for Windows and need to insert a certain number of rows into a table as a select from another table.
Im am not sure, if this is an issue of my old DB2 Version or if there is a general problem with my statement.
So I am looking for an alternative to it.
The task is to insert a set of ids into the table markierung, which is defined with 2 columns as
IDUSER INTEGER not null
IDBILD INTEGER not null
Straight forward would be to insert all corresponding items from other tables, e.g.
insert into markierung
select distinct
xuser.id as userid, xbild.id as bildid
from
user xuser, bild xbild, logbook xlogbook
where
xbild.id = xlogbook.oid and xuser.id = xlogbook.userid
This approach works fine, but I want to insert only a certain number of rows (the newest ones).
Therefore I would like to do something like this:
insert into markierung
select distinct
xuser.id as userid, xbild.id as bildid, xlogbook.date as date
from
user xuser, bild xbild, logbook xlogbook
where
xbild.id = xlogbook.oid and xuser.id = xlogbook.userid
order by date desc fetch first 5 rows only;
First problem: I need to add the date into the selection for using with the order by
because I want to insert the 5 newest rows. But the insert allows only 2 columns so
I changed the query
select userid, bildid from
(
select distinct
xuser.id as userid, xbild.id as bildid, xlogbook.date as date
from
user xuser, bild xbild, logbook xlogbook
where
xbild.id = xlogbook.oid and xuser.id = xlogbook.userid
) as xxx order by date desc fetch first 5 rows only;
The select statement works fine
But when I try to insert the selected results into the table markierung, I get an error:
I was using this statement:
insert into markierung
select userid, bildid from
(
select distinct
xuser.id as userid, xbild.id as bildid, xlogbook.date as date
from
user xuser, bild xbild, logbook xlogbook
where
xbild.id = xlogbook.oid and xuser.id = xlogbook.userid
) as xxx order by date desc fetch first 5 rows only;
This is the error:
SQL0104N At "BEGIN-OF-STATEMENT" unexpected Token "insert into
markierung select userid, ". Possible Tokens are: "".
SQLSTATE=42601
Do you have an idea, how I can insert only 5 rows into markierung?
Is there an alternative way or alternate query for inserting?
