    > So the format of the file reference for Branch A would be, A500/2024 and for branch B, B200/2024, etc. <<

    That sorta violates 1NF, right?  Personally I'd suggest not doing...

    Some things are somewhat unclear.

    I don't see "district" at all in the ERD, although you reference it extensively in your discussion.

    "Entries" is a rather vague Entity.  And it looks as...

  • Reply To: Decimal Datatype with negative value

    It should be more efficient to do that using a trigger rather than doing a separate UPDATE after the load.  The trigger would also allow for indirect notification (you wouldn't...

    I would think one UPDATE -- with the IN condition added -- would be much better than 3 separate UPDATEs, since the main table will then only have to be...

  • Reply To: Help with date range subquery

    Typically EXISTS / NOT EXISTS is most efficient when it's a viable option.

    You'll want to have a (nonclus) index on B ( AppId, NotificationDate ).  If the table already has...

  • Reply To: Help with date range subquery

    Agree with Phil, that's a critical q.

    Also, efficiency will depend on the indexes on the tables.  You'll need to be able to review indexes.

    Try these and see if they help.  Be sure to review the query plan to verify:

    INDEX ON mq: ( TABLE_NAME, ROWID_MQ_DATA_CHANGE )

    UPDATE mq
    SET mq.sent_state_id = 6,

    It would be simpler and more efficient to just calc the 3rd Friday of the month and then see if there are any rows for that date, i.e., you don't...

  • Reply To: Rebuilding/Reorganizing in a very transactional table

    I don't see why you'd need more then 150GB of RAM for a 31GB table.  If that's "the big table" in the db, presumably the entire is only 50 or...

    Agreed.  You really want to have all the dbs having the same owner.

  • Reply To: Query wont use any index - Cannot understand why

    We would need DDL for the tables and some cardinality info (how many rows for each condition).

    But, overall, IF that is a consistent query pattern, you should cluster the table...

  • Reply To: incremental load

    I prefer the 2nd approach, but for the 1st approach:

    Need sample data that is directly usable, that is, CREATE TABLE and INSERT statement(s), not just a splat on the screen.

    D'OH, sorry, that should be:
