Call a procedure only once for the last place of the trigger FOR EACH ROW

Hello world

I wonder if someone could help me in the execution of the trigger. My use case what follows:

-a trigger after each INSERT or UPDATE operation;
-use FOR EACH ROW algorithm for relaxation;
-collect certain values inserted/updated fields as: new.uuid and store in a set defined on the layer of the package;
-only for the last inserted/updated line call a procedure from the global collection with the values collected as a parameter;

Is it possible to be implemented for the type of the LINE FOR EACH of the trigger? Fact one: new identifier or trigger itself have special attributes such as COUNTY, SIZE to set a size of data inserted or changed to conditional logic? Is there another solution to possible workaround for thoughtful use cases.

Thank you

Andrey

Hi, Andrey,

I suggest you use 2 triggers:
(1) A FOR EACH ROW trigger, as you described, to collect relevant data and store it in a temporary table overall or variable poackage. Whenever the trigger is activated, it will overwrite all the data from the previous row.
(2) AFTER ( NOT FOR EACH ROW) trigger that calls the procedure by using the saved data.

    Hello

    I had the same problem. It seems that if you pass your columns to the columns in standard report it will fire for the checked columns. But if you proceed towards editable fields each line is treated as checked.
    So if you use line selector instead of manually creating check boxes and have a hidden primary key
    field, you can then use something like

    BECAUSE me IN 1.APEX_APPLICATION. G_F01. COUNTING LOOP
    UPDATE


    SET
    WHERE =
    APEX_APPLICATION. G_F02 (APEX_APPLICATION. G_F01 (i));
    END LOOP;

    I think that you need a stored function (which returns the value) in this case, is not?

    Take a look at:

  • Is it possible to find the two sentences into one pdf file? For example, I know the words 'Here' and 'the answer' occur more than once in my document, but only once on the same page. I'm looking for this page.

    Is it possible to find the two sentences into one pdf file? For example, I know the words 'Here' and 'the answer' occur more than once in my document, but only once on the same page. I'm looking for this page.

    I tried to do this by using the search but it will find only them, if they occur as a long chain, that is to say "Here's the answer" rather than how they occur in the document it is to say "Here 's" a bunch of information that leads you to 'the answer'. The search feature so standard did not help.

    Then I tried to do this by using the tool to delete (obviously not the application of writing!) because it allows me to search for multiple words or phrases, however it is not highlight what page both are found. I tried to turn on the preference to enable deletions of comments and even if it meant that I could then go through all the comments, it's still not faster than my document is more than 1,000 pages, which meant there were too many total comments for me to be able to easily identify which page had both.

    Any ideas?

    There is no built-in way to search for two strings and limited to show only the results that appear on the same page.

    It can be done by using a custom script, however.

  • Topics appear twice in the list of topics, however, each does exist only once in the project.

    Some subjects appear twice in the list of topics, but each exists only once in the project files. What are the causes for this and what can do to prevent it? I am using HR 11.0.4.291. I deleted the CPD file.

    Here is an example:

    Change in all files in a folder specific to say the first element. There may be two files in the same folder that Windows does not allow that. My guess is that the duplicates are in different folders and change the folder will help you find the original and the duplicate.

    Also open both the list of topics. Should be the red squares in it? If Yes, you have sort of a release in the source.

    Post back with what you find.

  • How to map the entered value of attribute column to another attribute in the table for each row.

    Hi Experts ADF,

    JDev 12 c.

    I create a button and a table below. If the user clicks on the button create, I invoke CreateInsert. The new line now appears as an editable fields.

    So I suppose I have a column that is displayed in editable mode. If the user enters values in that. Has another column B whose value is not displayed in the UI must have the same value as the column.

    This occurs for each row added. During the click on save if user entered 2 in column A, then the value in column B must be same 2.

    Thank you

    Roy

    There is more than one way, for example:

    Generate ViewRowImpl Java class (with generate audited accessors) you will get for an attribute setter.

    Change the Set accessor to set the attribute B (IE, calling setAttribute ("B", value)) after setting a value

    OR, write valueChangeListener for inputText representative and set the B attribute to the same value

    For each row, use the count property of cells. Since there a number of subject lines is the number of columns.

    Change your column on which you want to create the link

    go to declare attributes-> column change-> under the column link

    1. Select a text link (you have option available under the link text select one of these option)

    2 target - > application Page

    3 page-> page not on which you want to redirect

    If you want to pass a value then

    Item1-> select an item in the page detail2

    values-> that you want to move the page pos.1

  • Calling stored procedures with parameters with the database connectivity Toolkit

    Hi all

    I'm new to the forum and struggling to find a solution to a particular problem I have in this respect, using the LabVIEW Database Connectivity Toolkit on a project, I am currently working on my work.  I have a database in which I tables and stored procedures with parameters.  Some of these stored procedures have input, output and return parameters.

    I tried to follow this example, but to no avail: http://digital.ni.com/public.nsf/allkb/07FD130746083E0686257300006326C4?OpenDocument

    Such a stored procedure I am working on the implementation is named "dbo.getAllowablePNs", running "SELECT * from DeviceType" (DeviceType is the table).  In this case, it requires no input parameter, it has an output parameter that generates the table [cluster] and has a return parameter that returns an integer value (status code for execution) to show if an error occurred.  The DeviceType table has 3 columns; ID (PK, int not null), PN (nvarchar ((15), null) and NumMACAddresses (int, null).)  I have surpassed many examples and I talk to the support OR try to implement this and similar procedures stored in LabVIEW but have not been successful.  I am able to connect to the database with the VI of open connection without error, but spin in some confusion as a result of this step.  I then try to use the VI of parameter query create to call the stored procedure and set the parameters.  I guess I would then use the Set parameter value for each parameter that is connected to the entry of parameters on the previous query with parameters VI VI?  I am also having some confusion during and after these steps as well.  I would greatly appreciate advice or suggestions that anyone could have in this situation because I am not a SQL expert.  Also, I would be happy to provide more information that might be useful.

    Kind regards

    Jon

    Here's what I use to do this.  I think I had to change him create parameterized query VI for him to work.  There is a post on the forum about this somewhere.

  • Asking only once and the storage of information.

    Hello

    I would like to start for the FIRST time to have my application to request a phone store so that number number so when you are prompted for the end user can choose to receive a text on my Web site with out having to put in the number evertime.

    From what I've read here you can't just of the information with the user information.

    I can do AJAX and the popup box.  But the storage and the first part only once I'm a little to the 'green' on.

    Thank you

    Probably the simplest way I can think to do is through cookies.  You can set a cookie that stores the phone number and another that tells you if you have requested the digit preceding.  Finally, whenever you launch the app, you check the second cookie, if it has not set will prompt you for the phone number, otherwise do not ask for it.

    An introduction to the use of cookies with JS can be found here - http://www.w3schools.com/JS/js_cookies.asp

  • Only once at the start of the first image to sound

    I imported the sounds of my animation and visuals must be synchronized with the audio, they depend on each other. But whenever I need to replay to hear the audio, it only works if I start from the beginning. He is very good at the beginning, but I proceed with my movie, the more frustrating it gets. If I play in the Middle, the audio will be silent.

    I tried to find answers to this, I don't know if there is a simple option for this, or if this is a bug. Help, please!

    Sound can have different type of synchronization setting in the properties panel. To do what you want, you would normally define the flow, but that only works for AS3 documents, it is not available in HTML5 Canvas.

    If you are just an animation that will end in video, or just for the reading of office, use AS3 FLAS. If you do an animation for HTML5 Canvas, start with an AS3 FLA, do everything which animation to adapt the sound stream and then convert the FLA in HTML5 Canvas.
