Can I use wildcards in BFILENAME

Hi Forum,

I have a situation on my DB server, there will be files that I download in a table; but I don't know their first and last name.
I'm only starting and ending (extension) name like, 00667788xxxxxxxxxx. PDF
where xxxx... part of the name of the file that I don't know.

Can I use wildcards in BFILENAME?
for example, BFILE_LOC: = BFILENAME ('TEST', ' 00667788 *.) PDF');

Or is there an alternative way?

Please suggest, thanks and greetings.

And if there are 20 files matching the wildcard, which file should be opened?

Or is there an alternative way?

The list of files in the directory (Java stored procedures can be used) and determine the file name and use it-as required by the core of the operating system for the repair of the fopen() function call (file open).

Oracle does not open the file - as with other applications, he calls and uses the interface to call operating system I/O to open/read/write/close files. Therefore, the interface of the kernel that required the file to be identified uniquely in order to open it. I don't remember seeing a kernel call interface that support wildcard characters with the fopen() function call. Is simply not logical.

  • Can I use a wildcard character in a function?

    I want to search only for values that are not empty. Can I use wildcards for this?

    Here is an example. The data table above changes over time and fill empty values. I wish the bottom table is always current, with just the value more far to the bottom of the data table is displayed in the value column.

    HI Ted,

    SEARCH will search through the bottom of a column, but look for the first occurrence of the value, it is set to search. In this case, you are looking for A, B, or C, so SEARCH will return a zero for each.

    Given the empty cells in the last four lines of the column A, LOOKUP (A, table 1::A, 1::C) will return to the values

    Formula in table 2:

    A2: LOOKUP (A, table 1::A, 1::B)

    Fill to line 4.

    Kind regards

  • Open the file by using wildcard characters

    Anyone know how to open a file by using wildcard characters in the name.

    For example, a certain folder will contain a number of files, with the name built as follows:

    CALDB_ then a serial number with 6 digits and then 14 characters, which could be ANYTHING.  so it might look like this

    CALDB_123456_33KA1234567890.txt

    or

    CALDB_123457_33KA1234567890.txt

    The key part of the file name is the serial number of 6 digits that is unique and the CALDB_ which is always the same.

    I would like to use a command file with the name of the file as something like CALDB_123456_*.txt, but it doesn't seem to work.

    Can anyone help?

    Thank you

    Hi Dylan,.

    Along our forum, I searched and found a similar question for the use of wildcards in file selection. An active user (unclebump) has responded to this request with a VI, with which you can select a folder on your computer that is scanned for some files. I adjusted this VI to select CALDB_ files *. You will find this file (zipped), including my attached test folder.

    Maybe it will be useful for your application.

  • How to use wildcard characters in the filter REMAINS for subscription items

    I've followed this documentation:

    String columns filters

    Support the % operator (started by).

    Support * operator (contains).

    Can't stand (trimmed) operator.

    Examples:

    Name = service *.

    Name = * g *.

    Name = * g - unauthorized

    URL OF THE REST:

    http:// /RequestCenter/nsapi/serviceitems/serviceitemsubscription /=

    I can get the filters to work without wildcards, but have had no success in using ' *' or '%' characters  Please provide an example encoded URL appropriate for

    ServiceItemTypeName starting with "virtual".  I was not able to get all the data returned when using wildcard characters in a filter.

    Here is what I tried:

    ServiceItemTypeName = instant virtual server

    http://10.8.0.46:8080/RequestCenter/NSAPI/serviceitems/serviceitemsubscription/ServiceItemTypeName=virtual%20Server%20Snapshot

    answer: 200

    literal works as expected

    Hi Dan,.

    I don't think you can use wildcards here.

    Please see the integration Guide to 9.4. Section: "REST API-> Quick Reference.

    You will find a table of what features are supported for resources exposed by the API. There you will find a line for "All Service elements", and you will see that: get all the, sorting, paging and all filters are supported; Search for names of wildcards are not...

    When I came across this situation, I guess I'm trying to do a generic name search here... and it is not supported. This, however, works for the other columns (Designer if created), which is what, in my view, that documentation is trying to describe. (Although, personally, I feel that it is a bug).

  • Search Windows 0X80004005 error when I use wildcards and text empty

    Hi all.

    I hope you can help me. I am using Windows search, but my code throws an exception if I use wildcards (&, *, _,...) or empty text.

    My code is:

    string sentence = "Select System.ItemName, System.ItemPathDisplay, System.ItemUrl of creates where"+ ".
    "CONTAINS (" "+ this.). SearchString.Text + ' ') AND SCOPE = "file:myscope" ";

    Then I run the code, but I get the following exception if SearchString.Text is empty or a wilcard.

    IErrorInfo.GetDescription failed with E_FAIL (0x80004005).

    The directory where I'm looking is indexed and I select 'files and content '. If SearchString.Text contains a Word, it works correctly, but it does not work in other cases.

    Could someone help me, please?

    Thank you very much!

  • Using wildcard characters in the URL variables (very simple question, I know)

    Hi all!

    Pulling my hair out over this... How to use wildcard characters in the URL variables? I have this code in compositionReady (that works):

    var myurl = " " http://www.mydomain.com/Sub1/Sub2/pagename ";

    var currenturl = window.location

    if(MyURL == currenturl) {}

    sym.getSymbol("symbolname").play ();

    }

    It is simply the symbol "NomSymbole" play when the current URL corresponds to the variable 'myurl '. However, I want the symbol to play on all subpages of http://www.mydomain.com/sub1/sub2/ , and therefore, it seems logical to put in a wildcard as:

    http://www.mydomain.com/Sub1/Sub2/ * or something similar, but I can't seem to make it work?

    Any help will be greatly appreciated!

    :-)

    Best,

    Thomas

    What of it?

    var mysubdomain = "http://www.mydomain.com/sub1/sub2/";

    var currenturl = window.location.toString ();

    If (currenturl. IndexOf (MySubDomain) = 0) {}

    sym.getSymbol("symbolname").play ();

  • Using wildcard characters in the Script Map

    Hi everyone, im new in FDM and I have some doubts on mapping scripts.

    I have to recreate this translation in FDM Hyperion rule:

    ACC_SAP tm_sap Reverse sign UD4
    N21099Z300 {NULL} FAKE CD1
    D31199Z000 {NULL} FAKE CD1
    ???? 99 * FAKE CD

    ACC_SAP is the account of the source
    TM_SAP will be loaded UD5 (as looking up)

    How can I manage with a similar mapping?

    I guess the use of the script, but im not sure how to use wildcards wildcard in scripts, is - it possible?

    Another related issue, in an explicit mapping, how can I manage with NULL values if I want to assign [none] value, what I have to insert the value NULL into the field source th?

    BR and thanks

    As long as you're using wildcards in the source and them pointing to a single account, you can do all that you have demonstrated. All this is done directly in the similar table. No script is needed.

    ??? 99 * goes to the HFM_99 or whatever your target.

  • Can I use the Time Capsule wireless for multiple computers without using it as a router?

    I am looking for an external backup for 2 computers drive.  I have a desktop iMac and MacBook Air.  I like the idea of being able to back up my MacBook Air wireless, but I need to make sure that it will work the way I need to.

    I already have a wireless router that works well for me, I don't need the time Capsule to act as a router. I'm just needing a wireless backup drive.  So, the question is, can I use the only time Capsule as a storage device for backup of wifi or do I also have to use it as a wifi router?  My fear is that the router service is not as good as the router, I currently have.  I live in a big House of 2 floors, making it very difficult to receive a strong signal throughout the House.

    can I use time Capsule only as a backup wireless storage device or do I also have to use it as a wifi router?

    Time Capsule need to connect to your router/modem existing using wired Ethernet wired, permanent.

    If you plan to use the time Capsule to back up your Mac with the help of the application Time Machine on every Mac, the Mac will have to save on the wireless signal Time Capsule for the process to be officially supported by Apple.

    While it is possible to turn off wireless on the Time Capsule and try to save it to your existing wireless network... and it pourrait work... but there will be no Apple support backup problems... so it would be a good idea to plan to use Time Capsule wireless backup purposes.

    The seller should take the steps described in the following article management before selling the iPhone for you, including clear and, if it was enabled, removing lock Activation:

    If they have not cleared the iPhone, you should do before asking for yourself as the new owner.

  • Can I use time capsule as external hard drive?

    Can I use time capsule as external hard drive so that I can access a file or a specific folder by searching for its name?

    A TC is now and for always player network... no external. So there are limits to its use.

    If you are multitasking your TC with Time Machine and then using a DMG file as a virtual drive is better than directly copy files... However sharing becomes impossible. One person at a time can open the DMG.

    See pondini. T3 http://pondini.org/TM/Time_Capsule.html

    Old but still interesting to read.

    You can certainly create a folder on the TC and copy your files on it, and then perform a search. Research is slow on wireless is so the speed of transfer of large files. With the help of ethernet is certainly encouraged to desktop computers.

    Sharing folders on the TC is also now more difficult with increasing security at El Capo and OS later. You do not create on the computer records are not available. And even the ones you create can occasionally and autonomous change permissions (since the TC controls drive not the computer), you lock your own files on... I answer these questions once a week.

    Not all software on Mac supports using network drives. The most difficult is photos that can corrupt the library due to disconnections... which are the most common wireless. Be warned backups are important and not easy to do because of the slowness of the USB port on the TC and you end up really need to another location on the network for backup on.

    Generally, I advise the people not not to use the TC for direct files... That is to say, if you edit a document, make sure that it is on a local drive... When you have finished the document, you can copy it to the network drive and delete the local version. Easy for... not so easy documents for photos with major libraries.

    A TC cannot save itself and Time Machine backup impossible network drives... This means that no backup will be your files in the TC, unless you take the initiative and do it.
