What is the correct syntax to reference a page point (P23_ID, for example) in a process of PL/SQL page after submit?

What is the correct syntax to reference a page point (P23_ID, for example) in a process of PL/SQL page after submit?

TexasApexDeveloper wrote:

Variable binding is preferred: P23_ID you can also use & P23_ID. (variable substitution notation).

Bind variable and static text substitution references are not interchangeable. For example, static text substitution references cannot be used in allocation targets:

:P23_ID  := 'foo';  -- valid
&P23_ID. := 'bar'; -- syntax error (or something weird or sinister due to SQL injection)

Substituting static text references should be avoided in SQL and PL/SQL code because of the risk of behavior topic SQL injection and / odd error because of values containing quotes, etc.

  • Vista will not start! Black screen, no mouse, no cursor pointer. Startup Repair cannot repair. Details say 'wrong pass '. What is the correct syntax for pkgmgr to uninstall?

    Vista will not start!  Black screen, no mouse, no cursor pointer.  Startup Repair cannot repair.  Details say 'wrong pass '.  It looks like all the files are well intact on the disk.

    What is the correct for pkgmgr syntax when you try to uninstall an update by using a command prompt when starting Vista OS disk?  I entered the following in the "x:\Sources >" prompt:

    start /w pkgmgr/o: "C:\; /Up:Package_1_for_KB2840149~31bf3856ad364e35~x86~~6.0.1.0 C:\Windows.

    When I run this command it ends quickly and when I run 'echo %errorlevel%' I get '5', which seems to mean 'access denied'.  How am I supposed to have access to remove the patch?  Am I missing something?  Perhaps a switch in the syntax to access?  Help, please.  Thank you.

    I tried both options that you recommended.  As initially stated, no boot option would produce something other than the black screen.  I tried to boot from a drive and restoring the system running, but she didn't, and when I tried to do it again the recovery console could not find restore points. ?.

    An update, the computer is now fixed.  Oddly enough, I ran recovery of starting a drive at least 8 times and each time I checked the details and he said: he ran chkdsk without error and return to the same cause "a patch is preventing windows to start.  I even ran chkdsk c: /f from a prompt command from the recovery disk and it found no errors.  That's when I posted the question above after trying to remove the patch in the manner described above.  After some time and frustration, I decided to run chkdsk /r c:.  It took awhile, but it found 1 bad sector, moved the data, the bad sector tag and finished.  Once I restarted from that, everything came and went very well.

    So, the original question remains, what was missing in the command to run pkgmgr/high: successfully.  And the new question exists as to why start Recovery claims run chkdsk if it does not, or he turns the version/f not the version/r the same as I did manually?  It would be good to know for the future.  Thank you!

  • What is the correct syntax for the use of a variable in an ad-hoc query?

    Hi all

    I'm a casual user of the DB and right now need to update the records about 1000 + so that a certain column gets a unique value.

    So I thought I'd use a variable for this.

    Then, I built this type of SQL statement for only a small subset of records:
    ----------
    variable number recNumber;
    exec: recNumber: = 1;
    UPDATE TABLE_TO_BE_UPD
    SET COL_TO_BE_UPD = COL_TO_BE_UPD + recNumber
    WHERE COL_TO_BE_UPD IN ('VAL_A', 'VAL_B');
    ----------

    I get invalid SQL statement error when you try to run above (except for the guest who asks for a value I want to omit).

    In any case, I also tried this one:
    ----------
    CREATE SEQUENCE seqCounter;
    UPDATE TABLE_TO_BE_UPD
    SET COL_TO_BE_UPD = COL_TO_BE_UPD + seqCounter.NEXTVAL
    WHERE COL_TO_BE_UPD IN ('VAL_A', 'VAL_B');
    ----------

    Of it, I got the error ORA-01722: invalid number... I guess it's because seqCounter is of type number and the COL_TO_BE_UPD is of type character... (?)

    Then I want to ask is what is the correct way to define and use a counter variable type to add a number at the end of a string?

    Also another question I would ask is that are variables that are used in queries ad hoc, also called "bind variables"?

    Thank you muchly

    If you want to add a unique number to a column, then it would be:

    UPDATE TABLE_TO_BE_UPD
    SET COL_TO_BE_UPD = COL_TO_BE_UPD ||to_char(rownum)
    WHERE COL_TO_BE_UPD IN ('VAL_A','VAL_B');
    
  • What is the correct way to PAT outbound on a 5540 for VPN traffic?

    We lack 8.3 (2) in the ASA5540. Throughout our company, users connect to application of a business through the ASA/VPN partner. We have an address space of class b, and because users are spread in all directions, I have the entire space class b as the local object in the ACL that allows traffic through the VPN tunnel.

    The business partner is worried that our entire address space is available to access the VPN tunnel. So I thought, to help the aliviate concerns, PAT all our outbound connections to a single IP address.

    How this is done in 8.3 (2)?  ASDM to configure the 5540.  For example, our class b is 159.12.0.0 and the PAT would have IP address will be 199.30.36.6.

    You can try:

    purpose of group 159.12.0.0_VPN

    network-object 159.12.0.0 255.255.0.0

    purpose of group 199.30.36.6_VPN_PAT

    Home 199.30.36.6

    object group remote_location

    network-object

    NAT (interface, interface) dynamic source 159.12.0.0_VPN destination 199.30.36.6_VPN_PAT static remote_location remote_location

    I would only give it a shot... You would NATting twice he... (You should replace 'interface', 'interface' with the actual interface names. You probably already knew that.)

  • What is the correct syntax to a PDF form file name in the subject line of an e-mail. Doc Javascript?

    The name of the file is not part of any form field. The name of the file will be also unique whenever the form is used. I also want the name of the file that will be followed by the expression 'evidence' returned by the customer, as in:

    Topic: Proof of Papa Murphys SALEM 8 - 30.pdf returned by the customer

    Here is my existing script, but I need to know the syntax to get the PDF file name added in the subject line.

    this.mailDoc ({bUI: true, cTo: "[email protected]", bassujetti: "proof returned by the customer", CMSG: "attached is the signed evidence.}) Please send to the graphics dept '});

    I'm not very familiar with Javascript so have tried to reconstitute it.

    Unfortunately, there is only so much you can google to get a working solution, I would suggest that you get at least a little familiar with JavaScript (there are a lot of good tutorials and books available). If you want an introduction to Acrobat JavaScript, have a look here: Beginning JavaScript for Adobe Acrobat

    There is a property of the document object that returns the name of the file. You can read the property of Doc.documentFileName here: DC Acrobat SDK Documentation

    In the simplest implementation, you can use this to enter the file name in the subject line:

    this.mailDoc({bUI: true, cTo: "[email protected]", cSubject: this.documentFileName,  cMsg: "Attached is the signed proof. Please forward to the graphics dept"});
    

    If you want to add more information that just the file name, you will need to assemble your subject line by using variable elements and string constants. Something like this works:

    this.mailDoc({bUI: true, cTo: "[email protected]", cSubject: "The filename is " + this.documentFileName,  cMsg: "Attached is the signed proof. Please forward to the graphics dept"});

  • What is the correct syntax for function in SQL expressions filters?

    Hello

    I want to build a report that looks at the last dates 4 snapshot.
    I got every snapshot using this filter date

    Snapshot Date. "' Snapshot date" = TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (7 - dayofweek (current_date) + 2), current_date)) has
    now the second would:
    Snapshot Date. "' Snapshot date" = TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (6 - dayofweek (current_date) + 2), current_date)) B
    a third
    Snapshot Date. "' Snapshot date" = TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (5-dayofweek (current_date) + 2), current_date)) C
    a 4th
    Snapshot Date. "' Snapshot date" = TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (4 - dayofweek (current_date) + 2), current_date)) D

    for simplicity let's call filters A, B, C, D
    so, my sql expression should be something like the snapshot Date. "" Instant Date "in 'A', ' B', ' d ', 'C '.
    I tried to combine the underside, with hooks and comma separated, without brackets, with single quotes and without, but I always get a syntax error.

    Snapshot Date. "" Instant Date "in TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (7 - dayofweek (current_date) + 2), current_date)).
    TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (6 - dayofweek (current_date) + 2), current_date)).
    TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (5 - dayofweek (current_date) + 2), current_date)).
    TIMESTAMPADD (SQL_TSI_WEEK-10, TIMESTAMPADD (SQL_TSI_DAY, (4 - dayofweek (current_date) + 2), current_date))

    He doesn't seem to like the function IN either.
    Any idea?

  • What is the correct syntax to hide a div on the scene within two nested symbols?

    Hi everyone, I recently started using Adobe Edge and had some prior experience with Flash.

    I have a button with a click inside two symbols action that should hide a symbol placed on the stage, which in turn is the symbol of the mother.

    I tried to use the following code, but it did not work:

    SYM.$("STEP1"). Hide();

    Thank you!

    Nuno

    You must get the symbol in order to play, and in the above code, you access its handle jQuery (and not get the symbol). Try this instead:

    sym.getComposition () .getStage ().getSymbol("Step1").play ("Step1_fade");

  • The directory structure and using the correct syntax when using models of liquids and 'include '.

    Hello

    I have the following on my directory structure question when I want to use models of liquids with 'include '.

    If I place i.g this code on a model liquid 'layout - test.tpl ".

    {% include 'head' %}

    < section >

    {% block content %} {% endblock %}

    < / section >

    {% include %} 'footer'

    The models will appear without understands it. (On my desk works okay, because that the code compiles through "interprets" and will be shown in plain HTML.)

    Directories look like this (within the section of the administration console developer):

    Page layouts

    -Custom

    -includes

    ... header.liquid

    ... footer.liquid

    -models

    ... layout - test.tpl

    Obviously there is something wrong with my code to work in British Colombia.

    The main question is, what is the correct syntax to make it work?

    Thank you

    Kind regards

    Carla

    You can use no mixing to compile BC locally. BC is SAAS - Software as a solution, and you cannot compile it and its data locally. Simple as that really.

    You can use several file extensions to include in British Colombia. A common set of community is Inc. includes, .tpl for models, for example.

    I think the essential lack of your property is your liquid not application of the BC, your use of the syntax is incorrect and you try to develop locally which you will not be able to do.

  • What is the correct Version of software E20

    Hello.  I have an E20 which I am trying to set up.  After recording combined as 'root' via the cable from the console connected to the port, I have a problem.  When I entered the IP address information via the touchpad and the restart, he writes nothing to the unit.  When I am logged in as root to check, I see that I don't always have an IP address that is assigned to eth0.  When I hard code one in through 'root' for eth0, rises the interface and it works.  Then and only then I can web browse to the E20.

    I use the version of the TE4.1.1.273710 software which is what it came with.  Y at - it a version more recent and if so, please give the link.  I have not any other images stored on the device.

    The only way I could get it back by default with success has been to use this command from (date) "telepresence Endpoint technology Handbook": rm mnt/base/active/config.db.

    Note: the correct syntax should be rm /mnt/base/active/configuration/config.db

    You should should not unzip the pkg file, just download this file in the e20 through its Web page, or whatever your usual method for upgrades.

    Thank you
    Guy

  • What is the correct recovery process once upgraded to Windows 10? (No OneKey Recovery)

    I have a cell phone Z50-70 which is preinstalled with Windows 8.1. It is an OEM version, with the product key that is stored in the Bios. This is an installation of UEFI.

    The vehicle currently has OneKey recovery installed, which, if I understand well (I've not used actually still), allows you to recover from a hard disk recovery partition. This is not a "fresh" Windows 8.1, but an image provided by Lenovo that take back you to the State the laptop was bought originally (will have all software Lenovo and preinstalled drivers).

    According to the official upgrade guide Lenovo, before performing the upgrade of Windows 10, we should uninstall basically all software from Lenovo, including OneKey recovery and it won't work in Windows 10.

    Issues related to the:

    1. What is the correct process to recover the system from Windows 10 if something goes wrong? I think that Windows 10 integrates a feature "Reboot your computer" in the settings which I suppose is what we are supposed to use. It would take me to:

    a. a completely new install Windows 10?

    b. a created image during the upgrade from 8.1 to 10, containing all my files etc. when performing the upgrade?

    c. or he would use the recovery partition from Lenovo (which would have used OneKey Recovery if it was compatible) and take me back to 8.1 for Windows?

    (d) another thing?

    2. once I did the upgrade and Windows 10 has successfully activated, I think I could create a bootable with ISO of Windows 10, inside boot media and install a completely new install of Windows 10 and activate it. Theoretically, I could make as many fresh installs from the boot media I want, as long as initially, I did the upgrade (not a clean install), and the hardware of the laptop does not change. Is this correct?

    2A. If, therefore, during the first boot media clean installation process, I'd be sure compeletly remove the Lenovo recovery partition entirely and go from there, rely on 'Reset your PC' feature of Windows 10? Could I could use even just reinstall Windows boot again media 10 as a way to recover? If I understand correctly, it is not absurd to keep recovery partition it if it can not be used within Windows 10.

    I think I had a desktop PC ordinary with a retail version of Windows, then everything above would be fine. The complications added here are that 1. I have no product key Windows 8.1 (alll is managed by the BIOS) and 2. I have no recovery disk. I want to make sure that I understand everything completely before moving, and potentially do a clean installation using bootable media, so that I don't end up ruin something and end up with either a laptop I can not recover, a Windows installation that is not enabled.

    Thank you.

    Update for anyone of another reading:

    I just uninstall OneKey recovery on my installation of Windows 8.1 for the upgrade. While Windows is concerned, OneKey Recovery has been completely removed.

    The good news is that I then shut down the laptop, you press the novo button, selected "System Recovery" and I was always greeted with OneKey recovery program where I could choose to restore from original image, or a custom image. So I guess that once I have upgraded to Windows 10, I'll always have the option to restore to the factory Windows 8.1 if I ever need/want to.

    The confusion seems to be that OneKey recovery software is actually two separate software:

    1 OneKey Recovery #1 is installed in the hidden recovery partition which is responsible to perform a system restore from the image of your choice - either the image of plant or a custom image created by #2 OneKey recovery software. OneKey Recovery Software #1 is still accessible via the Novo button.

    2 OneKey Recovery #2 is installed on the Windows 8.1 installation, which is responsible for the creation of custom system images. You can also choose to restore the system from here, but AFAIK, it just restarts the computer and OneKey #1 software, which allows you to recover expenses. OneKey Recovery #2 is the software Lenovo told us to uninstall it before Windows 10. However, uninstalling OneKey Recovery #2 let software OneKey Recovery tact #1.

    As far as I know, this means that the uninstall OneKey Recovery #2 mean that we lose the ability to create custom system images, but we reserve the option to restore from a system image.

    Can anyone confirm that I understood, and that what I said above is indeed the case?

    I'm still a little uncertain about what Windows built tens in the willingness to ' PC ' do well - that it will use the Lenovo recovery partition or run a 10 Windows Installer Clean up.
