Re: Modify primary key for partitioning
>Update query would use Primary key, so why would you create index on RECEIVED_DATE or ('REVCEIVED_DATE','ID_MSG')?
Because I was wondering of creating the PK in the opposite way ('REVCEIVED_DATE','ID_MSG') so that a query with only the column ID_MSG in the where clause wouldn't use the PK.
