How can I manually refresh a Materialized View

Hi,
There's a materialized view created in 2006 as under:
CREATE MATERIALIZED VIEW "schema"."mv_name"
USING INDEX
REFRESH FAST ON DEMAND
WITH PRIMARY KEY USING DEFAULT LOCAL ROLLBACK SEGMENT
DISABLE QUERY REWRITE AS SELECT * FROM "[email protected];
The problem is that the last refresh was done in Aug. I want to manually refresh this materialized view right now as there is a procedure based on this MV and its not showing the right data as the above materialized view has not been refreshed, so the data for this month is not showing.
Please let me know how I can refresh that MV right now.
Also do I need to change the refresh option. How can I change it so that the MV refreshes itself every second.
Thanks

Also do I need to change the refresh option. How can
I change it so that the MV refreshes itself every
second. Every second? Why do you want to do that?? Perhaps waht you really want is refresh the MV on commit.

  • How can I fast refresh the  materialized view !!

    I created a MV base on some tables in order to improve the querey speed.
    but the mv I have created falied to refresh fast.
    because there are two same table in the from clause:
    jcdm jc1,jcdm jc2
    create materialized view temp_mv
    nologging
    pctfree 0
    storage (initial 2048k next 2048k pctincrease 0)
    parallel
    build immediate
    refresh force
    on demand
    as
    select
    TAB_GSHX.rowid hx_rid,
    TAB_GSHD.rowid hd_rid ,
    JC1.rowid jc1_rid ,
    JC2.rowid jc2_rid ,
    YSHD_ID     HXID,          
    JC1.JCDM     QFD,     
    JC2.JCDM     JLD     
    FROM
    TAB_GSHX,
    TAB_GSHD,
    jCDM JC1,
    JCDM JC2
    WHERE
    YSHD_ID=YSHX_ID
    AND YSHD_QFD=JC1.JBJC_ID
    AND YSHD_JLD=JC2.JBJC_ID
    AND TO_CHAR(YSHX_time,'YYYYMMDD')='20030101'
    the column msgtxt of the table MV_CAPABILITIES_TABLE is :
    "the multiple instances of the same table or view" and " one or more joins present in mv".
    How can I succeed in fast refresh the above temp_mv!!!
    thanks.

    lianjun,
    When you are using Oracle9i there is a procedure which can help you setup the materialized view. If some option isn't working it gives you hint why it doesn't work.
    The procedure is dbms_mview.explain_mview.
    Take a look at the documentation how to use it. (In the Oracle9i DWH guide the package is explained.)
    Hope this helps
    With kind regards,

  • How can I create index in a view?

    Dear all,
    How can I create index in a view?
    Best Regards,
    Amy

    A view is a stored query. It gets executed at run time. A view does not occupy any physical space in the database (other than the insignificant amount of space required to store the query in the data dictionary).
    A materialized view actually materializes the results of a query in a separate table structure, so it consumes physical space in the database. It also has to be refreshed at some interval, either synchronously with DML or asynchronously on a set interval.

  • Refresh of materialized views

    Hi there,
    i've got a question to the refreshment of materialized views: when updating or inserting / deleting data of some specific tables, my materialized view should be updated.
    First of all, i though to make that happen by using triggers on the specific table and the DBMS_MVIEW.REFRESH() mechanism. But as i have read pretty often, it isn't recommended doing that with triggers.
    But how can I get what I want :-)
    Thank a lot for your answers,
    Martin

    Thanks for your answers,
    the case with FAST REFRESH doesn't work. Our materialized are very complex and are using e.g subselect-statments, analytic functions,UNION, Order, Group by.... According to the documentation, we can't use the FAST REFRESH.
    Using the REFRESH ON COMMIT could be possible. Having a look at the documentation, there is one interesting sentence: A REFRESH ON COMMIT materialized view is refreshed automatically when a transaction that does DML to one of the materialized view's detail tables commits
    What are the materialized view's detail tables? Are that all tables in the FROM-Part of the query?

  • How can I pass field value betwen view in ICWC?

    Hi experts,
    I am new to this BSP programming. I have some requirements to modify standard ICWC in CRM 5.0
    Hope can get some advices and helps here.
    I have added a new field called <status> to context note SEARCHCUSTOMER in BupaSearchB2B view and also the same field name to context note CUSTOMER in BupaCreate view.
    I have added the field into both the HTM views and able to execute thru WebClient. However, I have one problem in passing the <status> value from BupaSearchB2B view  to the BupaCreate view when I click on the 'create' button.
    I do search and saw this thread How can I pass field value beetwen view in IC Web Client? , but i cant figure out how it works.
    Do I need to create the field <status> to context note CUSTOMER in BupaSearchB2B? Currently the context note does not have any attributes.
    Really appreciate for any help.

  • How can I manually transfer album artwork from my library to my iPod

    I downloaded album artwork to the songs in my library, and now I want to get the artwork onto the songs on my iPod classic. Problem is, I manually manage the songs on my ipod, instead of auto-syncing.... so when I hit the "sync" button in the latest version of iTunes (11.1.1.11), nothing happens. There also isn't a "show album artwork on iPod" button anymore. I'm afraid to change my settings from manual to automatic syncing, because I have lots of playlists on my iPod that aren't in my library, and I don't know if these playlists will be removed during the auto-sync. So how can I manually get the album artwork onto my iPod?
    Thanks,
    Rob

    You can only backup iOS devices.
    Sadly the old trick of removing all artwork and then adding it all back again no longer works. You may get some joy if you removed the specific album, then add it back again, butgenerally once things go wrong with artwork on a classic the only option is to restore it. Not a problem if all the media is in your library and you sync with a small number of selected playlists. If you don't have all the media see Recover your iTunes library from your iPod or iOS device.

  • How can i stay in time line view when i press record in garageband 1.2 for ipad. I know it's possible because i did it by accident, but i can't figure out how to do it again. It's driving me crazy....please help!!!

    How can I stay in the timeline view and not switch to instrument view when i press the record button in garageband 1.2 on ipad 2 ? I know it's possible because i did it by accident,but now i cannot figure out how to do it again. It's driving me insane......please help!!!

    After having experienced similar problems and having it back to work, I have a few suggestions:
    - Try to find out if the syncing stops at a particular track or song. That might - out of the blue - have gotten corrupted in one way or another. Since that song will not be on the iPod, iTunes will try over and over to put it on and crash in one way or another;
    - reformat the iPod as described in the iTunes 9 crash-thread. It takes time (at first it seems to do nothing, but that is because the green bar is moving with very small steps);

  • How can I create a full-screen view of Keynote slide in Snow Leopard?

    How can I create a full-screen view of my Keynote slides in Snow Leopard?
    I'm going to be importing into ScreenFlow to create a video.
    Thank you!!

    Welcome to Apple Support Communities.
    Do you want static screen captures or motion video of slides as titles, bullet points, and the like are presented?
    Run the Keynote slide presentation in full-screen mode, then...
    Static full-screen captures - use Command+Shift+3.
    Static partial-screen captures - use Command+Shift+4 and use cursor to select the area of the screen to capture.
    If you want motion video as builds occur, why not use Keynote's built-in Share, Export function?
    (I'm on iLife '09.)
    Also understand that the default slide format for Keynote is 1024x768, not full-screen MacBook 1280x800 screen size, so you'll have wide black borders unless you change the default size or crop the finished screen captures.

  • How can I select a date to view in Calendar while I am in month view?

    I am looking at month view in Calendar on my iPad. I touch a date. Intuitively, I expect that date to open up in Day or Week view, but it doesn't! On my iphone, it works just fine. Am I missing something?
    How can I select a date to view while in Month view and have it go to Day or Week view?
    Thanks for any help.

    I would try this:
    In Lr import one photo into a different folder that you can see in the list.
    Then in your OS (mac Finder / Win Explorer) move the photo to the folder that you cannot see.
    In Lr the photo will now appear with a question mark on its frame. Click directly on the question mark and select <Locate photo>. Navigate to the folder, open it, and click on the photo.
    Maybe this will help Lr to recognize the folder.
    If this doesn't help try renaming the folder in your OS.

  • How can I manually change the height of the "Type ...

    Hi all
    Just got automatically installed the latest 6.22 version of skype few minutes ago and I got a few questions. 
    First and foremost, how can I MANUALLY change the height of the textbox, where I type the messages. I would like to make it larger, like in the previous versions of skype. I don't want to move my mouse cursor through the entire monitor to reach this tiny textbox.
    And second, why you guys are trying constanly to ruin something that is working perfectly ? Going to revert to the previous version until you fix all these nuisances.
    Regards

    There is no way to do this, it is designed to be strictly landscape with keyboard, portrait without - not the best thought-out phone on the market, mainly geared towards compulsive texters and e-mailers.
    There's no way to know whetherNokia will change this with any future updates, perhaps you should make the recommendation to them directly using the 'contact us' link.

    Auto sync is not working. How can I manually transfer music from my macbook pro iTunes to iphone 5? My iMatch is turned on and I can direct downlad my music to the iPhone from the Cloud; however, I want to direct import All of my music from iTunes to my iPhone 5 via the connecting USB cable and it is not working. Yes, I have tried restarting both devices, and no autosync is not working nor is is it providing the avaialbile option to select music in iTunes on my Mac to then sync. Please help. Thanks

    Please disregard. I figured it out. Answer for anyone else running into this problem: You have to turn off iTunes Match on both devices. Apparently, if you activate iTunes Match it deactivates your abiltiy to direct sync.
