What are the benefits of the VAL?


What are the benefits of the VAL?
And
Why is it good for the database?
and
What is a safety precaution?


for ex

CoID = #Val (CoID) #.

VAL ensures that the entry is a numeric value and returns a number regard so she can ensure that the entries do not conflict with a definition of type of DB and throws errors.

Personally, I prefer to validate using IsNumeric, as VAL may return a value of 0 if the first didgits of the presentation are in fact digital, but not the rest.

  • What are the benefits should the software Intel offers compared to Win zero configuration

    (Satellite M60, Intel 2200BG)
    A few months ago Intel released new software WLAN (a major problem for the security, etc.). Initially, there was a memory leak problem, but he was soon fixed. However, they always seem to be a resource hog: there is the CPU usage in the Task Manager on the cob of 10 to 20% every 5 seconds all the time, also WIFI turned off & off, overall performance is affected - this can be seen for example in the tests of hard drive.

    I noticed that in order to use windows to configure WLAN & then kill two switching processes (iFramework, S32EvMon (?)) eliminates this activity.
    Recently, new Intel drivers are offered by Toshiba also, so I'm about to reinstall them with the option "drivers only".

    Anyone know what are the benefits should the full Intel software offer compared to Windows zero configuration?
    As far as I know, monitor event S32 is supposed to improve coordination Intel WLAN and LAN, working together.

    The new package is about 50MB in size, while the former was 2MB.

    Hi Sammo

    You have already preinstalled new driver? The package is really about 50 MB and Intel PROSet utility.

    I can tell you that offers software Intel the same configuration options of Windows. Maybe Utility Intel PROSet is friendly and kind but designed WLAN Windows settings by using, you can exactly the same.

    If you have more info on the download package and installation please let us know.

  • What are the benefits and drawbacks of shredding MFT space?

    Original title: MFT Shreading

    Can someone tell me the advantages and disadvantages of shredding space free MFT, I heard a lot of different accounts of the benefits to do so.

    Hello

    Grate way to remove a file or folder completely so that it cannot be recovered.

    The reason why we need to destroy unused disk space, is that when you delete a file from your hard drive, it does not get deleted from your drive hard data from the index to the file system entry is deleted. And the space that is occupied by these data is marked as free and made available for the storage of new data on it. But it is that deleted data still there exist on your hard drive physically.

    If you have deleted your data sensitive hard drive, which is secret, then it is advisable to opt for the destruction of unused disk space where the deleted data are hidden. By doing so, you can achieve the security and confidentiality of your data. What are the advantages, disadvantages could be that if you grate a folder and go back, you only may not be able to that it will be gone forever. He must be careful that crush us.

  • BlackBerry smartphones, what are the benefits of using the spindle to spindle and BBM?

    I have not used BBM again but was compose and send messages pins (peer-to-peer). Is this the same thing as the BBM and what are the benefits of each? Are they better than just SMS?  Would like to have an explanation, because I'm confused!  Thank you!!

    BBM and PIN messages are messages sent from one BlackBerry to another.  The message is composed by the sender and goes through the secure server of the RIM before being delivered to the recipient.  They are only available for BlackBerry users.

    The thing I like about them, it is how you can see if they have been received by the recipient.  Once the message reaches the recipient's phone, you will notice a small would be "at the beginning of your message.  In other words, that it is delivered.  When the recipient opens the message, who had "will change to a 'R' for 'reading'.  So now you know that it is actually received by the recipient.

    One more great thing about these messages, it's that there is no length limit.  As you probably know, most carriers limit SMS 160 characters; not the case with these messages, they can be much longer.

    BBM and PIN messages are of the same type of message, but with PIN messages, you are limited to just contact reception.  With BBM, you can have a lot of contacts on a cat, or you can broadcast a message to multiple contacts at the same time.

    I hope this explains things for you.

  • What are the benefits (if any) of transcoding to an intermediate editing for post production format?

    I have searched for an answer final to this day and impossible to get something useful.

    My recordings to the AVCHD format that is 24mbps H.264 video and audio camera (I record audio separately so audio is not a cause for concern). I use the following Adobe CC on Windows. I do a lot of green screen work.

    I read on many intermediate codecs designed for video editing. Include DNxHD of Avid, Apple ProRes, Cineform of GoPro, MXF OP1a, among others. As I understand it, these formats offer excellent features help video publishers to do their work.

    I was able to edit files directly AVCHD with Premiere Pro and after affects.

    My question is, what are the benefits, if any, I'd get if I converted my content from AVCHD to one of the intermediate formats before as I have start to change? It would speed up Adobe software? It would provide the best quality in the end? It would make various effects function better?

    Ultimately, all the videos I do will be encoded in the format h.264 for web distribution.

    Please note: I am not asking the workflow easier or more obvious (which is just to work with AVCHD files directly). I want to know if I can gain advantages in transcoding in another format before I in post-production and that these benefits are specifically for each of the different intermediate codecs.

    Thank you.

    Well, every format has its own advantages and disadvantages. Higher end codecs tend to be very large and take much more space, but behave better when apply effects or greenscreen work.

    However, you cannot really improve the quality that comes from your camera, it is an indispensable part of the workflow. You CAN transcode to, say, ProRes HQ and get better results with your fx work, but it will be as good as something turned on a higher end camera.

    Maybe do some tests on a small piece of video. Transcode into several codecs and do exactly the same treatment to all clips, including your original. Then compare them and see if the improvement is worth your time and additional hard drive space.

  • 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.

  • What are the (VARIANT OPAQUE) opaque types?

    A number of types of oracle as XMLType, Anydata and lcr$ _row_record are defined in SYS 'AS OPAQUE VARYING (*).
    USING THE LIBRARY.

    I wonder what is it? The only thing in the documentation I've found is "Oracle OPAQUE Types" of the SQLJ Developer's Guide. (http://docs.oracle.com/cd/E11882_01/java.112/e10590/objcoll.htm#i1008113)

    But I could not understand how it relates to PL/SQL. How can I make my own opaque type?

    What are the benefits of the opaque types compared to the normal PL/SQL object types?

    >
    In "The PL/SQL language Reference" book it nothing on this "AS OPAQUE VARIABLE", so how do I use just TYPE CREATE or REPLACE to make an opaque type?
    >
    There is no syntax like "AS VARIANT OPAQUE."

    When I said

    what I mean is that the types of Oracle you create is "opaque", in the sense that at the level of the instance object is just a series of bytes. You can access different components by using the dot notation.

    The data cartridge doc I cited goes into detail of how to create them; It is not just call them OPAQUE types. But functionally, they are since the internal components are concealed to Oracle. You must implement the cartridge interface functions that manipulate objects of your cartridge and Oracle Oracle does not or record what the internal structure is.

    The doc you city also explains how to create in Java that implements the appropriate interface.

    As a user, you need to focus on how to implement the functionality, you need and do not worry about the question of whether a class or an object, you create gets listed as OPAQUE in the dictionary.

  • What are the advantages and disadvantages for the largest block size and

    What are the advantages and disadvantages for the largest and the smallest block size block size?

    Smaller size of block

    Benefits
    Relatively large GoodHas air space due to metadata
    (i.e. block the header).
    Not recommended for the outline. He could only
    be stored for each block, or worse, a few lines line
    If one line does not fit into a block, for small lines with a lot of chance of chaining
    access.
    Reduced block contention.
    Disadvantages
    A relatively large air space due to metadata
    (i.e. block the header).
    Not recommended for the outline. He could only
    be stored for each block, or worse, a few lines line
    If one line does not fit into a block of chaining.

    Larger size of block

    Benefits
    Lower overhead, so there is more
    room to store the data.
    Allowed to read a number of lines in
    the buffer with a single I/o cache
    (according to the size of line and block size).
    Good for very large or sequential access
    lines (for example, LOB data).
    Disadvantages
    Waste of space in the buffer cache, if you
    random access to small lines and have a large block
    size. For example, with a size of 8 KB block and 50
    size byte of the line, you will lose 7 950 bytes in the buffer
    When you make a random access cache.
    Not good for the index used in an OLTP blocks
    environment, as they increase the claim to block
    on the leaves of index blocks.
