HOWTO: retrieve FK constraint "on delete set null" info from dictinionary?

Hi !
Selecting from USER_CONSTRAINTS column DELETE_RULE only lists "CASCADE" or "NO ACTION" but not "SET NULL". Is there another table I can use?
TIA,
Stefan

Hi Again,
after a short coffe break I found the solution myself: in Oracle8i the view definitions for USER_CONSTRAINTS is wrong. The decode for DELETE_RULE just misses value 2 in column REFACT for "SET NULL".

  • How do i delete my sons info from my i cloud account

    how do i delete my sons info from my icloud account

    There's no way to automate this process, it has to be done manually.  And you'll have to first migrate a copy of the data to a different iCloud account on his device before deleting any data.  If you delete it before doing so, it will delete the data from iCloud and from his device and it will be permanently lost.
    To do this, on his device go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off.  When prompted choose to keep the data on the iPhone.  After everything is turned off, scroll to the bottom and tap Delete Account.  (This will only delete the account from this phone, not from iCloud.  Your phone will not be effected by this.)  Next, set up a new iCloud account on this phone using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On.  When prompted, choose Merge.  This will upload the data to this new account.  At this point you will have two different iCloud accounts, one for each phone, with identical data on them.
    You will then have to go to icloud.com on your computer and sign into each iCloud account separately and manually delete his data  from your account, and vice versa.  These changes will be reflected on each phone.  When finished you will have individual iCloud accounts with just your own data on them.

    To remove it from your account, tap on your id in Settings > iTunes & App Store and then tap on 'View Apple ID' on the popup and log into your account  - that should give you a payments link on your account's page from where you can change remove/change your payment details.

  • How can I retrieve the col data size and Null information from table using labview connectivity toolset

    Hi, there,
    I am wondering how to get the table information by labview database
    connectivity toolset. The table list vi comes with the toolset can get
    only col name, data type and data size. And I found the the data size
    always gives back -1, even though it is a string type. Do somebody has
    some idea about it?
    Thanks.
    JJ

    JJ,
    Go into the diagrams of the DBTools List Columns and DBTools Get Properties respectively. When you inspect this diagram, you will see the raw ActiveX properties and methods called to get the size information. The value of -1 means the requested recordset is already closed. This is the sort of thing that is controled by the driver (ODBC, OLE DB, Jet, etc) you are using. Notice that you can right click on the property and invoke nodes and get more information about these specific items directly from the ADO online help.

  • How can i get the last delete picture's info from tlf?

    if i delete the picture from the tlf i can't make the tlf undo
    and I want to get the picture'info with I last time delete from tlf 

    Can you let us know what you are doing to delete the picture, and also how you are undoing it? If it is being deleted through the EditManager delete function, the delete should undo correctly. Some example code to illustrate the problem would help.
    Once the picture has been deleted, TLF has no further reference to it. If you want to keep a reference, you will have to get it before it has been deleted. If you don't have control over the delete, you could find out when the image is deleted by listening for FLOW_OPERATION_END events.

  • Trying to delete nike+ipod info from nano- HELP!

    I received the nike+ sport kit as a gift. I decided to return it as I already have a gps system to track my runs. I walked around my house 3 times with the system, and cannot figure out how to delete it from my nano for good. Any idea on how to delete the partnership?

    Here's what you need to do:
    From the nano's main menu, click on Settings, then click on Main Menu, then scroll down to Nike+iPod to toggle it from "On" to "Off." When you return to the main menu, Nike+iPod will be gone.
    Hope this helps!

  • How do I delete all my info from 3G

    Before I sell it?
    If I do a restore wont it load the info back on?
    Thanks

    You can also go to settings, general, reset, erase all content and settings. This will take a couple hours so plug it into power.
