How we force a query to use transparently a hint, even if the index is not given in the query as a query rewriting.

How we force a query to use transparently a hint, even if the index is not given in the query as a query rewriting.

For example:

If the user runs a query select deptno, avg (sal) from emp group by deptno;

We want the optimizer to use a hint of result_cache with this request, and it should be transparent to the user.

Query should be rewritten to seamlessly

Select / * + result_cache * / deptno, avg (sal)

WCP

Group of deptno;

How can this feature we make? Please advice.

I checked the possibility of SPM and contours, but it is not clear if this rewrite is possible here.

Thank you and best regards,

Vikas Krishna

Surely dbms_advanced_rewrite is designed for this situation?

  • How can I get Firefox to use more than 12.5% of the capacity of my modem wireless?

    Only if you use Firefox, pages take forever to load. Use of my wireless router in looking, I found that it runs in general (with just Firefox, no other program running on the internet) to 0% or 0.0%, with few spikes up to 5%. Even when you try to view a video.

    When I download something, it could rise to more than 12.5%, for a bit, but I never saw that he hit even 50%.

    When I'm doing something which seems that it takes more ability to my router, Firefox instead takes a bit of my CPU, I'm guessing that there is a lot to ask where are the packets of data or something.

    I have no proxy, or restart Firefox update worked, nor has completely rebooted my computer. I adjusted my network connections down, then back to the top, and all that did was make it so that I can't watch youtube videos, which she usually takes me a few tries to load in a resolution that will not hurt my eyes, and it is with an add-on that makes it so that they are forced to play in HD!

    OK, it's alright with the ISP part - I thought, as had shown activity wireless adapter testing with IE more like what was expected.

    I've also updated the two FF (not something I want to do, as it rarely is compatible with my Add-ons update. My set up is fine, it works, why should I change to something that will not be?), and an update of the computer (which, Yes, I should do it more often. A final which will automatically but has been massive, however and literally broke my copy of FireFox. It was boring!).

    I still feel like it runs too low, but at least the videos loading and read without problem now-well, for the most part.

    They load, kick up an error for a few moments and then screen reload and then play correctly. I guess I can live with that.

  • How do I change fields to be Transparent when you fill out the form?

    I have created a form to be completed by others.  Right now, in mode complete all fields are blue.  When I click on them to type, they turn white as I want to, but when I finished typing and go click on another field, it becomes blue but still has the text.  It really sucks because I already have lines in places where people with type.  How can I change all the fields to be transparent or white, so they don't show up?

    It is not an actual color of the field it's a highlight color for the application. You can disable it via editing - Preferences - forms.

    Info sought to assess the size of the required inverter.

    Found a few details about the ability of power.

    Formula:
    Watts = amps x Volts
    Amps = Watts / Volts

  • How to force Firefox to Android to use LTE instead of WiFi?

    Firefox for Android AUTOMATICALLY reconnects to the WiFi if I have NEVER connected to the WiFi in the past. Sometimes I want to use WiFi, and sometimes I want to use LTE with Firefox. How can I force Firefox to STOP using the WiFi connection and use the LTE connection? Note that simply kill WiFi on Android does not work; Firefox simply uses his past knowledge of the WiFi network and access code to launch WiFi alone. I HATE the apps that think they know better than the user...

    Sorry, the user misfires (once again for the millionth time, I guess).

    WiFi was set to "Auto-connect" at the launch of applications of high-usage data. Switch is in settings, connections, WiFi (tap to set up). I never watched here because I've always had the 'OFF' WiFi and thought (wrongly) that there was no switch configuration for a feature that was 'OFF '. Live and learn. Sorry again to waste your time; Maybe this will help another smartphone newbie...

    Thanks much for your quick, complete and CORRECT answer to my question, Roland.

  • How to force use of the VM a specific host in a cluster?

    I use vSphere vSphere Web Client 5.5 thru 5.0U2.

    When I create a virtual machine, I specify a host in a cluster as computing resources.  However, when I turn on the virtual machine, it uses another host.   How can I configure the virtual machine to use only a specific host in the cluster?

    Use the DRS-> Virtual Machine Options to disable the level of automation for the virtual machine. Who will be actually anchor her to this host. You could also put the VM on local storage or attach too to a resource (DVD-ROM) on this host, but the road of the DRS is the best way to go.

    Apple frowns on a decline in the ratings.

    While Apple allows, try downgrading to 9.3.2.

    For a limited time Apple will return you to the previous version.  Do not hurry.  This period takes up to a week.
