>>FIRST_VALUE (inbound_seq_pk) OVER (PARTITION BY miss_object_id ORDER BY seq_nbr ASC)

This is NOT like table partitions and has nothing to do with them.  the 'partition by' clause of a data warehouse window function like FIRST_VALUE is the same as a 'group by' clause on a regular select.

It tells the function how to group the 'window'.

this means, group the records by miss_object_id, then order by seq_nbr ASC and get the first_value

also the query you posted is not complete, it requires "FROM someTable" clause...

sorry about that...
attached the corrected file... change-this-query.txt
The relevant part of the query is actually this:


UPDATE aqtit01.tqt_it_inbound_seq PARTITION(INBOUND)


Can you post the table definition (including the partitioning).

I think you will be able to replace the PARTIITON(INBOUND) by an additional WHERE clause that specifies the equivalent of the partition values for INBOUND.
