Difference between spaces reserved & formulas

Hello

I used formulas. Placeholders also seems same as formulas, then what is the difference between them and what situation the spaces reserved are useful

If you have time please let me know the difference...


Thank you

Here's the difference...
Placeholder
Place support column is the column where we can define the global variable and that variable is used in the columns of formula for different calculations. column support palce is a global variable of the report.

A placeholder is a column for which you set the data type and the PL/SQL value that you set.

You can set the value of a column in the space reserved for the following locations:

01.the before report trigger, if the placeholder is a level of report column

02.A report level formula column, if the placeholder is a level of report column

03.A formula in the space booked group or group below (the value is defined once for each record in the Group)

If we want to return multiple values according to our logic we will use place holedr column in the formula column.

Formula column
The formula column is used for the calculation of the logic required for the report. formula column will calculate the value based on our logic, it will return a value.
A column of formulas makes a calculation defined by the user on an another data column (s), including the columns of the placeholder. Colums formula should not be used to set the values for the parameters.

Hoping to understand...

If someone answer is useful or appropriate, please mark accordingly.

    difference between freespace and unused

    Hello jilosaul,

    Because I didn't exactly know how to state the differenc, look at the link of WikiAnswers:http://wiki.answers.com/Q/What_is_the_difference_between_unallocated_and_free_space_in_Windows_Vista
    Unallocated space is a space not partitioned on a disc. According to the number of partitions on the disk, you can create a primary or extended partition with unallocated space.

    Free space is available in an extended partition space. This can be used to create a local drive in the extended partition.

  • Difference between available and used space

    Dear team,

    can someone please explain to me the difference between the provision and the disk space used in simple words.

    concerning

    Mr. VMware

    The summary above capacity data store is interpreted as follows: -.

    The capacity is the total size.

    Put into service space is the total size allocated to virtual machines.

    Free space is the space not exhausted by VMs again.

    Therefore, with a provisioning, you can provision the amount of space to virtual machines based on the free space at the time there. A virtual machine can be allocated to 100 GB but only use 50 GB. The unused 50 GB remaining is counted as part of the free space. This can be seen also by clicking on the tab "Virtual Machines" of the data store to see the "put into service space' and 'space used '.

    I hope this helps.

  • the difference between the intermediate process and materials first in BCP formulation?

    I do not understand the difference between the intermediate process and materials first in BCP formulation. could you give me an example to show the difference?

    The intermediate process - questions all the specifications that are used in the

    current specification.

    Raw - questioned the level of material first in the hierarchy.

    Hello Terry,

    It is used in the screen output Formulation based PCA. You can configure different PCA rule which is available in formulating exit point BOM, then when you start a screen of PCA in the base of the exit, you will see this rule.

    And the difference between the intermediate process and raw in PCA, let me explain with an example, I have a configuration hierarchy as below:

    OutputA

    A formulation

    Material X

    Output B

    Formula B

    Material M

    Material N

    If I select the output B in formulating A framework, and when I run a screen of PCA in the base of the output, I have three options:

    High level - it allows to extract A output attributes as PCA review the settings;

    Intermediate processes - it to retrieve attributes material X and B output like BCP review the settings;

    Raw - it will extract attributes of material X, output B, M and N of material material as PCA review the settings.

    I hope this helps.

  • Formula of FormCalc to make the difference between two time fields if they are populated - help please


    Hello

    I have a laptop (TotalTime1) which refers to two other cells in the updated hour-shaped (Start1 and 1 to finish).

    The formula below is intended to make the difference between the time of departure and of arrival if they are populated.

    I had to work unconditionally HasValue, but the formula was calculated when there is no value in the Start1 and Finish1 (due to the time format).

    This is the code I have, it is said that there is an error of almost the last line; I'm sorry if I'm posting this in the wrong way, I haven't posted on this forum before but this is:

    If (HasValue (Finish1) and HasValue (Start1)) then if (Time2Num (Start1.formattedValue, "HH: mm") < Time2Num (Finish1.formattedValue, "Hh: mm")) then Abs (Time2Num (Start1.formattedValue, "HH: mm")-Time2Num (Finish1.formattedValue, "HH: mm")) / (60 * 60 * 1000) another 24 - ABS (Time2Num (Finish1.formattedValue, "HH: mm")-Time2Num (Start1.formattedValue, "HH: mm")) / (60 * 60 * 1000) endif

  • difference between BYTE and CHAR

    Hi all

    Oracle, as in syntax below, what is the difference between BYTE and CHAR used as size data type for the column NAME:

    CREATE THE CUSTOMER TABLE
    (
    NAME VARCHAR2 (11 BYTE),
    CUSTOMER_ID NUMBER
    )

    and

    CREATE THE CUSTOMER TABLE
    (
    NAME VARCHAR2 (11 CHAR),- or even VARCHAR2 (11)
    CUSTOMER_ID NUMBER
    )



    Rgds,
    PC

    First - do not use reserved words for column (NAME).

    If the database character set is UTF-8, which I believe is the default value in the recent version of Oracle. In this case, some characters take more than 1 byte to store in the database.

    If you set the field as VARCHAR2 (11 BYTE), Oracle will allocate 11 bytes for storage, but you can not actually be able to store 11 characters in the field, because some of them take more than one byte to store, for example, non-English characters.

    By setting the field as VARCHAR2 (11 CHAR) you tell Oracle to allocate enough space to store 11 characters, regardless of the number of bytes it takes to save each of them. I think that in Oracle 10g, 3 bytes per character were used.

    Kind regards

  • Difference between iCloud &amp; iCloud Drive?

    (1) what is the difference between iCloud and iCloud-Drive?
    (2) how to transfer photos on the iPhone 6 iCloud Drive?
    (3) when the images are in the drive, can I remove them from the 'camera' - ' 'Gallery '? and they will remain on the drive?

    Thank you to those who can help
    Karni

    iCloud made only in iCloud, is usually not the part where you would hold pictures, it would be iCloud library that synchronizes your photos on your selected devices.

    With iCloud library enabled, you cannot delete a photo on a device (or iCloud.com) without deleting each device which uses iCloud photo library (iCloud.com). In order to save space on your mobile devices (and indeed your Mac if you want to) turn on the optimization of the pictures on these devices (settings > photos & camera > optimize storage on your mobile device and Photo preferences > optimize storage on your Mac)

    Dynamic optimization, it reduces the resolution of your photos, if necessary, so that you don't notice it occurring initially. However, when necessary, it is very effective, and users have reported libraries being optimized for much less than 10% of their original size in some cases. My own library is about 9% of its original on my phone size.

    In most cases, optimize your photos should be enough to alleviate space issues on your device. However, if you have an exceptionally large library you may need to disable iCloud photo library on your mobile device and use instead the photo stream. You can then use a computer to manage the photo stream photos and have them automatically imported into you iCloud photo library.

  • Y at - there a big difference between the base of the m3 and m5 models?

    I had my m3 2016 Macbook for a week so just thought I would ask so that I have time to exchange it if need be. I wondered outside storage space, y at - it a big difference in processors Core of m3 and m5? Apple uses a "customized" version of the processors? I ask because Apple lists the m3 1.1 Ghz but not apple models are call at 900 mhz.

    The processor is clocked at 1.1 Ghz. There are different models made by Intel, including that which is supposed to be clocked at 900 Mhz. Apple does not use a customized version of the CPU. The differences between the M3 and M5 model is displayed on the Intel Web site. Among the differences are the M5 is clocked at a higher speed and the M5 is generally about 15-20% faster than the M3 at the same clock speed.

  • What is the difference between Apple Watch sport and Apple Watch?

    What is the difference between Apple Watch Sport42mm space aluminum case gray with Strip black sports and Apple Watch 42 mm space with black Sport band black steel box?

    Hi Mathias

    There is no difference in the features of the software or the specifications of internal material between the Apple Watch models (with the exception of a few faces of exclusive watch on Apple Watch Hermès).

    The only differences are the materials used - including watch boxes, tapes, and views.

    For example: Apple Watch Sport models are designed to be as light as possible, using aluminum and glass aluminosilicate for the screen. Apple Watch models use heavy stainless steel case and sapphire glass for the screen.

    Your best option may be to make an appointment to try on Apple Watch in an Apple Store, see and feel the difference.

  • Difference between the cDAQ-9174 and cDAQ-9178

    I have several cRIO-9081.  Each cRIO-9081 running NOR-DAQmx 15.5.  On four of the cRIO-9018 we show you cDAQ - 9178 with 8 modules.  Everything just worked.  On the fifth cRIO-9018, we tried to connect a cDAQ-9174.  The aircraft appeared in the Windows Device Manager and MAX, but MAX has indicated that the aircraft was missing (error-88705) and that Windows can't find a driver for the instrument.

    We then plugged a cDAQ-9178 in the fifth cRIO and everything just worked.

    What is the difference between a cDAQ-9174 and cDAQ-9178 other than the number of the module support?

    Paul

    Hi Paul,.

    It seems it could be a driver problem! What DAQmx version you have installed on two computers? Reinstall the latest version may be worth it because it looks like there may be corruption. You can find the latest version here: http://www.ni.com/download/ni-daqmx-15.5/5901/en/

    You can manually associate the device driver, here: http://digital.ni.com/public.nsf/allkb/5B80CAAA64413B4C86256C5E0000C1A7

    There are modules connected to the cDAQ chassis?

    Also, sometimes, this can happen if you do not restart your computer after the installation of the NOR-DAQmx driver. Restart your computer after the driver installation will allow you to reserve the device successfully. Here are a few others not to try:

    • Check the charger to device OR to see if it is running

    • Reset the service OR charger

    • Reset the MAX Configuration database

    • The system power cycle

  • What is the difference between AXIEM and EMSIght? What are the benefits of AXIEM by EMSight if any?

    I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.

    AWR estimated AXIEM most powerful plan EM Simulator around.   AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws.  Here is a summary of the differences:

    Mesh

    • EMSight must mesh the nearest grid drivers using rectangles.  This causes the mesh to have more elements mesh when there are small and large geometries.  The grid should be small enough to capture the small geometry but then causes large geometries to mesh more.   In addition, angled or curved structures causes inefficiencies mesh.

    • AXIEM STS forms, rather than a grid.  In addition, the mesh can be rectangle or triangle.   This allows a much more efficient mesh.   AXIEM generally have a much more efficient

    • AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh.  EMSight does not have this feature.

    • AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)

    Ports

    • The ports are for the most part similar, but parasites due on AXIEM ports are less.  In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.

    • Ports can be added to most any place in geometry with AXIEM.  For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.

    Problem solvers

    • EMSight does not have a low frequency Solver.  Stop low-frequency and then extrapolate to DC.  This usually works well, but you must take into account if the extrapolation is accurate.  AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.

    • Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment.   It has a special algorithm to break the question of memory, but the question of time is the killer.  AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn).   In other words, AXIEM can solve a lot of bigger problems than EMSight.

    • Several AXIEM processes are multithreaded as EMSight.

    Speaker

    • EMSight is inside a perfect driver side wall.   This works well if you the circuit is in the same cavity.  If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes.   AXIEM is not here.   AXIEM does not currently have to simulate a perfect driver side wall.

    I don't know that I missed a few aspects of the tools.   From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

  • U3014, the difference between CAL1 and CAL2 modes?

    In the preset mode color space for U3014 30 "monitor, what is the difference between CAL1 and CAL2? I tried both, but couldn't say a diff.  I know they are both precalibre mode that comes with the monitor.  Any info will be appreciated.

    course at 100%.

    Look, in these internal calibration of monitors's done it with a 3DLUT. The native range is greater than AdobeRGB (in red).
    Standard and modes Custom comes with native and native range WhitePoint (GBLED whitepoint, colder than D65 native), custom mode allows yo to set your desired white point.
    At the factory, 2 calibrations are stored in LUT3D and they are NOT editable by the users (but can be corrected by GPU):
    AdobeRGB: R, G & B coordinated (especially red coordinated), white point, and gamma of 2.2. 2nd is not very accurate.
    sRGB: R, G & B coordinated, white point gamma and sRGB. 2nd is not very accurate.

    AND as typical, monitor allows yo to store values of x LUT3D 2: CAL1 and CAL2 but it only works with the Dell Solution of Calibration color (DA), and DA only works them with i1DisplayPro.
    CAL1 and CAL2 are just "USER SLOTS" for the storage of LUT3D calibrations, nothing more.
    To the factory settings, they should behave in Standard mode.

  • DataGuard protection mode - difference between max and max performance available

    Hi all

    for maximum performance - transaction can commit both redo entries are written in redolog on the main site. Redo data is written to an asynchronous backup site.


    (T1) the main site to the backup site connection fail, recovery of desynchronization logs will sync on once the connection is established?

    to see availability max - transaction can commit both redo entries are written in redolog on the main site + 1 of the standbysite.  If the main site to the backup site connection fail, it will behave as performance Max once the connection is restored, he will return to the max availability again.

    (Q2) if the main site to the backup site connection fail, recovery of desynchronization logs will sync on once the connection is established?

    Q3) in this case, what is the real difference between mode 2 above?

    Kind regards

    Noob

    Q3 - performance Maximum does not wait do it write in standby when the standby is available; is maximum availability. If the reserves are not available, they are the same.

    Q1/q2 are the same question and the answer is 'yes '.
