Before you remove the trigger

Forms [32 bit] Version 6.0.8.11.3 (Production),

Hello

I have a master / detail hangs, I update a table, and the update process is based on registration of removal of the retail block, so

I created a before delete trigger on the block of retail and wrote the declaration of update in it, and it worked fine when I tried to delete a record directly from the retail block, but

When I tried to remove the main record that causes all the detail records should be deleted because the property 'Behaviour of delete record' "cascade."

the update process is not the case, what is the problem that I do? What should I do to make the process of update happen?

do not delete makes it master record "Before Delete" trigger on the detail to the fire?

Thank you

There are at least two solutions.

One (which I like) is to write code in a database trigger (after HAVE DELETE ON detail_table FOR EACH ROW).

Another way is to add the code at the beginning of the DELETE pre trigger forms (the block details):

FOR (IN) cur_detail

SELECT...

OF detail_table

WHERE master_id =: master_block.id)

LOOP

...

END LOOP;

--

-Start default relationship program section

--

BEGIN

--

-Program section Begin DETAIL_BLOCK detail

--

DELETE FROM detail_table d

WHERE d.master_id =: master_block.id;

--

...

Kind regards

  • How to save a virtual machine before you remove the disc

    Very new to VMWare, with Essentials 5.5 the VSphere Client.  I have a virtual machine, I would like to remove from the disk, but want to copy, in the cases where I need to turn the crank upward once again, the host before the withdraw. Is it fairly easy to achieve?  However, I have to remove the inventory, by copying the file to the vm from the data store, add it to the inventory then disconnected the floppy again.  Would support this work if I already needed to put the virtual machine?

    Thanks for any idea!

    You can download the files of the virtual directory of the data store computer and that you need to remove the inventory, just stop the virtual machine to release the locks on files.

  • Error message: unable to save this article before you save the header entry

    Hi all

    I'm trying to insert data into the table of okc_k_processes using an API. When I run my application, I get this error message: unable to save this article before you save the header entry. I tried to open the API package body and locate the error but could not find it. How to solve this?

    Thanks in advance.

    No, there is no trigger on the table. But what he really tell by the error and to save the header entry?

    We do not know your code, and we do not have access either!  So, how are we supposed to know what a particular error message?  You can not save the ticket before you save the header entry is NOT an Oracle error, it's a validation error request that someone who wrote the API set.  We can only guess why you get it.

    Your API call should be to create a detail record and requires that you create a header record.

    The validation is

    • okc_contract_pub.create_contract_process and one of its dependencies
    • pa_interface_utils_pub.get_Messages
    • a trigger on a table.

    run the following

    Select *.

    from ALL_SOURCE

    where the TEXT like '% you can not save this entry before saving the header entry %.

    and you'll probably find where.

  • I'm retouching of images taken on my iPhone 6 more with Photoshop CS6. I'm doing my color correction and add effects and all that. Before you export the image I review and be sure to what I has no more sharpness and the lines are smooth and it looks good

    I'm retouching of images taken on my iPhone 6 more with Photoshop CS6. I'm doing my color correction and add effects and all that. Before you export the image I review and be sure to what I has no more sharpness and the lines are smooth and it looks good overall. I export it to JPEG, max quality with the establishment of reference standards. I then open the image and it seems fine, as it did in photoshop. My problems begin to occur when I try to download on Twitter as my profile picture. I tried downloading from my office directly on the site via google chrome. When I download the image then begins to have jagged edges and overlooks the tablets. So I thought it was some performance settings, then I tweaked them and restarted a couple of times and still the same result. He would go on my desk but when uploaded to twitter as my profile picture is horrible. So I tried emailing the image of myself and the download through my phone. I opened the image on my iphone and it seemed fine as he did on my desktop but when I downloaded the image it makes then look blurry. I had this problem when downloading photos Twitter via my iphone, so it doesn't surprise me. I have read different forums saying: you must download it from the office, so I thought it would work like this. This could be a problem of twitter than compresses uploaded photos? Other people can do very much the same way, but it does not work for me. Please someone help me before I put my computer in an oven microwave.

    This could be a problem of twitter than compresses uploaded photos?

    Yes. The rest, we can answer. You wrote a lot, but very little discussion. Instead of accurate information you lose yourself in the vague descriptions. Screw color management to the wrong dimensions that trigger resizing server-side it could be any number of things here.

  • How to clear the output buffer, possibly resize and burn again, before you begin the task of output

    I use PyDAQmx with a USB-6363, but I think the question is generic to DAQmx.

    I have an output buffer that I want to be able to (re) write to without starting the task output.

    More specifically, I have a graphical interface and a few sliders, the user can move.  Whenever the slider changes, a new set of values is loaded into the buffer output through DAQmxWriteAnalogF64.  After you set the value, the user can click on a button and start the task output.

    In some cases the change in cursor does not require a change in buffer size, only a change in the data.  In this case, I get the compalint following DAQmx as they tried writing:

    The generation is not yet started, and not enough space is available in the buffer.

    Set a larger buffer, or start the generation before writing data more than content in the buffer.
    Property: DAQmx_Write_RelativeTo
    Value: DAQmx_Val_CurrWritePos
    Property: DAQmx_Write_Offset
    Corresponding value: 0
    Property: DAQmx_Buf_Output_BufSize
    Corresponding value: 92

    In other cases the change in cursor requires both change in the size of the buffer and data modification.  In this case, I get the following, but only after that do a few times each time increase the size of the writing.

    DAQmx writing failed because a previous writing DAQmx configured automatically the size of output buffer. The size of the buffer is equal the number of samples written by channel, so no additional data can be written before the original task.

    Start the generation of before the second writing DAQmx or set true in all instances of writing DAQmx Auto Start. To gradually write to the buffer before starting the task, call DAQmx Configure an output buffer before the first writing DAQmx.
    Task name: _unnamedTask<0>

    State code:-200547
    function DAQmxWriteAnalogF64

    I tried to configure the output via DAQmxCfgOutputBuffer buffer (in some cases, by setting it to zero or a samples, then save again, in an attempt to clear it) but that doesn't seem to do the trick.

    Of course, I can work around the problem by loading data only when the user clicks the end button, but not what I'm asking here.

    Is it possible to "remake" the writing of output before you begin the task?

    Thank you

    Michael

    Today I have no material practical to validate, but try unreserving task before writing the new buffer:

    DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Unreserve);

    With a simulated device, he made the error go away in case the buffer is the same size.  You will need to validate if the data are in fact correct, but I think it should be (unreserving I would say reset the write pointer so the old buffer are replaced with the new data).

    I always get errors when you try to change the size of buffer if (on my 6351 simulated).  I posted some similar mistakes about the reconfiguration of the tasks here, I guess it is possible that this issue has also been set at 9.8 (I always use 9.7.5 on this computer).  If the behavior is still present in the new driver, and also appears on real hardware (not just simulated), then it seems that this is a bug of DAQmx someone at OR should be considered.

    I wrote a simple LabVIEW VI that captures the error in order to help people to NOT reproduce it:

    The best solution at the moment would be likely to re-create the task if you need to change the size of the buffer (or avoid writing data until you are sure what will be the size of buffer).

    I want to start using the "Master password" feature. There are a couple of hundred passwords 'stored' in the tab Options-Security-Saved passwords so I wonder if it would be better to remove ALL these before you set up a master password. I'll be change and delete several of the "stored" passwords in any case. But my main question is whether the 'master' password all the 'stored' existing passwords and what happens if they have already been composed anyway surfing crypterait?

    Passwords current al will be encrypted with the master password if you set one, which includes the passwords that you have already saved. There is therefore no need to delete the current passwords.
