How to check which function was used in a function based index.

Hi how can i check which function was used in a function based index created on a column.
Thanks

Hi,
What is your requirement... !!
Bascially performing a function on an indexed column in the where clause of a query guaranteed an index would not be used. From Oracle 8i onwards introduced Function Based Indexes to counter this problem.
Any how check this..you will get an idea..

  • I brought apple lightining cable from authorised shop , but my i phone is not getting charged with that how can i know its orginal or not there is no printing on that cable and the wire is little harder than which i was using before it came along pho

    I brought apple lightining cable from authorised shop , but my i phone is not getting charged with that how can i know its orginal or not there is no printing on that cable and the wire is little harder than which i was using before it came along with phone.., Please let me know is the cable is orginel or not ..

    the phone says it is not charging even though it actually is. Check and see if that's the case. A very underhanded trick by Apple so they can charge 10 times what the cable is worth. They do not win admirers by that proprietary trickery.

  • How to find which datasource is using table JCDS?

    How to find which datasource is using table JCDS?

    Hi,
    Please find the below link and identify whether will it meet your requirement or not ... If it meets your requirement then I can provide you more documents related to the same which we have in our project.   We were using the same for Plant Maintanance project...
    For this report the required information is gathering from the different data sources from the ECC system. This report requires object status functional location attributes, Equipment attributes and some specific information apart from normal transaction data for an order.
    u2022     Main feeding data sources for this report are 2LIS_17_ORDER and 2LIS_18_ORDER.
    u2022     Requires the object status data (system status, number object status and un-number system status) is feeding from different DSO where the status data is staging with different data flow.
    u2022     Requires the Order planned end date which is dependent on the operation  planned completion date. so we are feeding this field from Operationu2019s DSO where the planned date is staging with different data flow.
    u2022     Required characteristic data and attributes of the Functional location  is getting from the master data .The 0FUNCT_LOC is updating by master data data sources
    u2022     Required standard class  of the functional location is updating from other DSO where the  classification  data is staging with the help of different data flow.
    2LIS_17_ORDER and 2LIS_18_ORDER Data flow Details : No enhancement was done for these data sources .
    Status Data Flow Details:
    The status data is staged because ,this dat is required for the reports based on the Orders, Operations , Notifications, Functional Location and Equipment.
    To load suitable data to different DSOs from the Status DSO we maintain the Filters for status profile and status at DTP level.
    Required status change dates  are deriving based on changed on date ,system status while loading from status DSO to Order DSO.
    The system status ,Number object status and un- numberd object status are feeding from status DSO only.The status DSO is updating by u20180TE_OBJ_STATUS_HISTu2019.This Is based on the tables JCDS,JSTO and T000.
    JCDS     MANDT     =     JSTO     MANDT
    JCDS     OBJNR          =     JSTO     OBJNR
    T000     MANDT     =     JCDS     MANDT
    This DS has enhanced for the below  two fields
    1.     Order Number
    2.     Operation/Activity Number
    The Logic to populate the above two fileds is as below.

    Rosetta can have a 2GB RAM "tax" to manage PowerPC code as well as how that affects performance.
    I think real world performance shows both statements to be wrong; consider this:
    If that were the case, how come Apple does not include that information in its Snow Leopard installation requirements, since Rosetta is an optional install?
    Also, running a PowerPC app on an 2011 i7 Mac with Snow Leopard will run faster than running that PowerPC app on a PowerPC Mac.

    how to check which version of hyperic is installed , hyperic 32 bit or 64 bit version on solaris

    If you have only a single home, the quickest/easiest way is probably just to check the properties of %ORACLE_HOME%\odp.net\bin\2.x\oracle.dataacess.dll
    Or are you asking how to check it at runtime?
    If you want to see externally what is actually loaded by an app you can use process explorer

  • After reopening Firefox does not remember which desktop was used for each window. Can you help, please.

    I'm using two displays and several desktops on my Mac (OS X 10.9.4).
    When I need to restart Firefox, it remembers to open windows from last session in correct display, but does not remember which desktop was used for each window. So when the application starts, it opens all windows on a desktop which is currently active instead of reopening them on desktops used during the last session. How to fix the issue?

    Hi Nerva,
    Thank you for your question, there is a add on I have been recommended to custom set up of opening windows in new monitors. It's called [https://addons.mozilla.org/en-US/firefox/addon/monitor-master/ Monitor Master].
    However, in regards to the session remembering which monitor the window was open in, in the profile folder there is a file that stores window positions and dimensions. It is called localstore.rdf.
    Please stay tuned for more investigation, as there are definitely bugs on file for similar issues. Pinpointing it is the hard part.

  • Determining Which License Was Used To Install Snow Leopard

    A few months ago, my company purchased two Mac Minis with two Snow Leopard Server licenses.
    For various reasons, we want to do a clean reinstall on one of the Minis, but we can't remember which license we used on which Mini.
    Is there a way to tell from the machine which license was used to install the OS?
    Thanks much,

    Have you checked in Server Admin or System Profiler for the key number? Not sure if it's there, but worth a check. Beyond that, I'd suggest calling Apple Support.

  • How to identify which applicarion is using the DVD burner?

    How to identify which applicarion is using the DVD burner? Ot is not allow me to burn the DVDs genetrated in the Final Cut 7

    I think you'll find that the application is Final Cut Pro...  the message is bug.  I get a similar message when disconnecting external drives after using them with FCP (even when the project is no longer loaded.)
    As I mentioned above, the accepted workflow is to export the sequence to one of your hard drives using the Export>QuickTime Movie path with Settings:Current Settings and Make Movie Self-Contained checked like this:
    This gets you a high quality "master copy" which you open in Compressor for transcoding. You should use the DVD: Best Quality setting for the duration of your movie.
    this gets you the high quality MPEG-2 and AC-3 files for DVD Studio Pro authoring.
    If you've never used DVD Studio Pro before, you can use iDVD instead. For iDVD, you just drag and drop your "master" on iDVD and it takes it from there. Both make a very professional product.
    hope this helps.
