And it will not only check for the key constraints but also build the access 
paths for all the indexes and this can make the INSERT slow... untill unless 
they are *DLY ....

Antonio -
The DB2/400 file manager still has to check all of the the unique keys over
the file to determine if you are violating any key constraints before
actually inserting the record.

So I would say it is possible that the answer to your question is yes, you
are wrong...
