How to run the trigger child block before the block parent?

Y at - it anyway to run the child block trigger before master block?
In fact, I have a parent block having 3 blocks to the child on a form. I would now, when the user runs Delete_Record integrated with a push button, then first of all it must run before you remove the trigger 2nd child block, and then click the 1st installment of the child and the parent block.
If this sequence is not respected, form gives me error that exists to book the child and violated foreign key of the table of block parent. I already set the property of relationship to the waterfall.
So is there a solution?

I could have spent a little more time thinking about your question. {: 8} is the issue. Because the relationship is not cascade past the first child, an event "Dele you" don't occur in blocks of Parent and 1 child. Therefore, on child blocks 2-5 Pre - led summer triggers do not fire because there is no case of "elete" D in the blocks for the triggers to respond too. I think the best option is to use the trigger before Dele you on the parent or blocks of 1 child.
>
PS... I can dele given you children tables without any error of block-1 pre D elete in descending order. But I don't think it better option. >
Hope this helps,
Craig B-)

    Hello Nri,

    What value does P18_SCHOOL_ID?
    If you look at the State of Session (toolbar) developer. If that does not have a value, it's your problem.

    You can create a calculation before the process that gives the correct value. (In one case more often, you have a report and when you click on the link change that id is activated and you see the recording in your form)

  • Lean how to run the stop code when the highest level VI ends

    Hi people.

    I am a newbie of LV with 30 years of experience in embedded SW engineering.  I searched for how to run the stop code when a VI of highest level ends.  I found many examples, but they are horribly complicated.  A little birdie told me that such a model of simple design should not be so compilicated.

    My application is an application of high tension control to disable all HV checkpoints when the SW ends.  My VI code is running in a while loop with a stop button that leads out of the loop.  I can easily accomplish my requirement by programming with a sequence of plate that runs after the end of the main loop.  The technique of flat sequence does not work when the user clicks the Cancel button in the toolbar of façade, more than that market when the user clicks the close button of the application (X button) when you run the exe application.

    Can someone tell me please a simple technique, the code example that can show me a lean and elegant way to accomplish my task?  It doesn't have to be an obvious solution (for example a stop induced watchdog seems simple enough).

    Thank you - John Speth

  • How to run the Extendscript .bat file?

    I have a file with some instructions .bat and I want that it runs from Extendscript.

    How to run the Extendscript .bat file?

    I tried execute(); order and it seems that .bat ran but no result, but when I double click on the .bat file all worksout very well.

    How used runtime.exec () extend the script?

    Can I communicate with Java JDK thru ExtendScript and run commands such as runtime.exec ()?

    can someone please?

    You can do it like this:

    var batFile = new File("C:\\path\\to\\my\\batfile.bat");
    batFile.execute();
    

    Note that this will only work if your system is configured in such a way that by double-clicking the .bat file runs it in reality.

    You can also use

    system.callSystem()
    

    but note that this is only available in AE.

  • How to identify the primary Parent of a shared node?

    We have a property that is set to Local defined, inherit,

    Suppose the 'Color' property and currently is the behavior in DRM

    Parent A - blue

    Child 1 - blue (inherited from Parent)

    Child 2 - color blue (inherited from Parent)

    Child 3-color blue (inherited from Parent)

    Parent B - Red

    Child 3 ~ part 1 - red color (inherited from Parent B)

    Child 4-color red (inherited from Parent B)

    Children 5 - red color (inherited from Parent B)

    The customer has improved the requirement so that in the case of shared members 'color' is inherited from the primary parent like the example below.

    Parent B - Red

    Child 3 ~ action1 - blue (inherited from "Primary" Parent A)

    Child 4-color red (inherited from Parent B)

    Children 5 - red color (inherited from Parent B)

    I guess I'm going to need a new property like 'Primary colors' and I need to write a formula to calculate the color of base on the primary parent.  However, I do not know how to identify the "main Parent" a shared node we use version 11.1.1.2 N-Tier

    I'm looking for suggestions on how to calculate the value of the property you want.

    Any help will be greatly appreciated.

    Hello

    You can create a new property derived like u said and use instead of the property defined in your exports or anywhere where you have to refer to the color. The property set can be used just to take the user input.

    The new derived property should be a logic like that-

    If (PropValue (Core.SharedFlag_MDM),

    NodePropValue (PropValue (Core.PrimaryName_MDM), Custom.Colour)

    PropValue (Custom.Colour))

    Now, 11.1.1.2 I lost the memory of how the properties are referred to as - if they are just used with their names or namespaces is mentioned (Core. , custom.). You can change the formula accordingly to view properties

    Thus, if SharedFlag_MDM is True, then it will take the value of the property to its primary node, which is inherited from the primary parent and if the shared flag is False then it is just a varValeurProp on the node itself.

    I hope that answers you.

    Thank you

  • How to run the application startup script before the start of telnet (inetd)

    Hello

    I need to run my application startup script before the beginning of Telnet users on the server. At the present time, the script is at /etc/rc2.d/S98startup which is not useful.

    Thanks in advance...

    Published by: user4027740 on April 7, 2012 12:41

    I am inclined to ask 'why', but I refrain...

    The problem you'll have is that 'telnet' (really inetd) will be started by SMF and your app startup is a legacy script. I don't know of anyway to you allows to map addictive SMF one departure inherited. The only solution is to write a start of SMF for your application and do inetd:default require your application to be online before you start.

  • How to run the rman output files, which are more days of retention

    I use for my rman backup tasks.

    I have format my output files of rman to a specific path, instead of the fast recovery area.

    Also, I spend below command in RMAN

    RMAN > CONFIGURE RETENTION POLICY to RECOVERY OF 7-DAY WINDOW;

    And the "control_file_record_keep_time" parameter is also set to 7.

    I've been running rman for 8 days. Everything seems good. But I find several rman output files are more than 7 days.

    So, I just want to know how to handle the rman output, which is longer than 7 days files?

    In fact, I assumed that these older files should be obsolete files, but rman is not to declare that they are obsolete.

    So how do now?

    Windows 7 day average recovery rman will protect everything necessary for the recovery to any point in time in the last 7 days.  In fact, in the last 604800 seconds.  The same will mean that he need the files OLDER than that.  Simply because a backupset is older that your recovery window does NOT as yet, it is obsolete.  Any recovery begins with the last FULL or INCREMENTAL backup ZERO before the recovery point.  And it does not matter how old the backup is, it will be obsolete.  Suppose you take a level 0 backup, 1 January and for the rest of the year taking nothing but level 1 and backup archivelog.  31 December than and only the full backup will still not be obsolete, even though he is a year old.

    On day 14, your window of 7 days is up to date 7.  A recovery to date must begin by restoring the backup of level 0 of the day 1. So it may be outdated.  Some level 1 between 1 and 6 days backups might be obsolete, depending on if they are incremental or cumulative, and it also happens with archivelogs.

  • How to run the script with parameters such as alarm action .ps1

    Hello

    I know not how to configure alarms, I know that I can point to monitor cluster for changes (via the GUI), but... I have different groups and I would like to set an alarm by vCenter which monitors cluster for changes. Let's call it "RefreshCapacityInfoOnExternalDB".

    So, lets just say. I would like to run my script whenever a virtual computer is added, Reconfigured or ESX host are removed, added in a Cluster. The alarm would launch the .ps1 script written in turn the ability to update external db cluster info.

    Shortly said: ability to cluster values are changed

    What I need is this: run the script-> CapacityInfoRefresher.ps1 < Cluster_name_where_ReconfigEventsTookPlace >

    I guess that, first I need an environment variable (if it exists) that can be used as a parameter for the < Cluster_name_where_ReconfigEventsTookPlace > placeholder script. Right?

    Chapter 16 of the book of LucD & Friends "PowerCli reference" mentions some environment vars but I'm stuck. Anyone using these options?

    THX

    A.S.

    You can set your alarm on the node above in your vCenter tree, this way it will be active for all collections in the vCenter.

    These alarm environment variables are automatically available for your alarm script when it is triggered.

    These environment variables, you will be able to determine to which cluster the alarm was pulled.

    So I don't think that you need to pass this information as a parameter to the script.

    Perrhaps you could share what exactly alarm you want to set and what looks like the script which should trigger alarm.

    And Yes, I use these environment variables in scripts of alarm
