Cannot change the type of data in the columns referenced by foreign keys

Hello:

I'm using Version 3.1.0.691 and change the types of data in many columns of data derived from the field types. If a column is referenced by a foreign key, however, the data type radio buttons are grayed out. I suppose that if I deleted the foreign key, that I would be able to change the data type of the column to a field, but that would be tedious. Is there another way to go about this?

Any help would be greatly appreciated.

Thank you

Doc

Hi Doc,

If a column is referenced by a foreign key, however, the data type radio buttons are grayed out.

It is not good - if you have the PK column, and it is called by another FK column you can change the data type of column PK and FK column data type will follow the change. You cannot manually change the data type of column FK. Good column PK itself could relate to another column, and in this case you cannot change the data type of column PK.
In your case - you need to find the first PK/Uk column that is not the column FK itself and change its data type. FK columns in the chain will follow.

  • Cannot change the column in Table

    Hello

    Well I have a table called T1 where I have some columns with 70 000 lines in this table.
    now I need to change a size of datatype of columns of 5.2 to 5.4, with the command below.

    SQL > alter table t1 modify column_name1 number (5.4);

    When I run this command I get the below error

    ORA-01440: column to change must be empty to reduce the precision or scale

    So what I did is based on the table in another table t2 and now deleted all t1 lines.
    Once again, I have changed now the column modified successfully to (5.4)
    But even once when I insert the backup to the top of table t2 in t1 I received this error below.

    ORA-01438: value larger than the precision specified for the column


    the table t1 column_name1 number (5.2)
    changed as column_name1 number (5.4)

    now why can't I could insert the values inside by a backup table?

    pls help.


    Concerning
    Stanlee.

    As the previous man said, you must change 7.4 like accuracy then try to insert. It's that workout.

  • Cannot change the Google search bar

    In Safari, I go to Google.com and do a google search. So far so good.

    Now, on the search results page, I try to edit the search in the Google search bar and nothing happens - the Google search bar is totally insensitive. To do another search, I use the address bar in Safari or reload google.com.

    I have deleted history, deleted all the data of the Web site, disconnected plugins and extensions, deleted the cache via the menu Developer. I used 3 CleanMyMac to clear and reset everything.  I can't solve the problem.

    Safari 9.0.2 (11601.3.9)

    OS X El Capitan 10.11.2

    Mac Mini (late 2014)

    'CleanMyMac' is a scam and a frequent cause of instability and poor performance. Depending on which version you have, the developer's instructions may not completely uninstall. Please follow these instructions, then do as below.

    Please, back up all data before proceeding.

    Triple-click anywhere in the line below on this page to select this option:

    /Library/LaunchDaemons/com.macpaw.CleanMyMac2.Agent.plist

    Right-click or Ctrl-click on the highlighted line and select

    Services ▹ reveal in Finder (or just to reveal)

    the contextual menu.*, a file can open with a selected item. If so, move the selected item to the trash. You may be prompted for administrator login password.

    Repeat with this line:

    /Library/PrivilegedHelperTools/com.macpaw.CleanMyMac2.Agent

    Restart the computer and empty the trash.

    You may also delete one or more of these elements in the same way:

    ~/Library/LaunchAgents/com.macpaw.CleanMyMac.helperTool.plist
    ~/Library/LaunchAgents/com.macpaw.CleanMyMac.volumeWatcher.plist
    ~/Library/LaunchAgents/com.macpaw.CleanMyMac3.Scheduler.plist

    Never install "CleanMyMac" or something like that.

    * If you do not see the item context menu copy the selected text in the Clipboard by pressing Control-C key combination. In the Finder, select

    Go ▹ go to the folder...

    from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  • Microsoft Movie Maker - cannot change the length of each clip.

    Cannot change the length of each clip on Microsoft Movie Maker.

    I clicked on 'tools', then 'options' in Microsoft Movie Maker after importing my media and organize my clips as the way I would like it. When I then click on the "Advanced" tab, image duration shows only 5 seconds with the transition period only 1.25 seconds, which is the default setting and that is also what I want. However, when I play my project in Movie Maker, it accelerates through each clip. I also noticed that when I press the title of 'Clip' in my headings at the top left and then click on 'Properties', the duration of each clip shows that only 00:02 seconds. Which is why my speed clips too quickly.

    I would have thought that setting my time of duration in the Tools section would then set in the Clips section, but this is obniously does not. I don't understand why everyone would show differently and wonder if you can help me to slow down the speed that my movie is playing.

    Thank you

    ================================
    The change of setting to: Tools / Options /.
    Advanced... tab applies only to the added clips
    to the timeline * after * you change the setting.

    If you switch to view "Storyboard" and select
    all of the clips as a batch (select one and the type...
    CTRL + A)... you can add the 'Speed Up, Double.
    or "Slow down, half" effect of changing the
    duration. Simply select all clips / right click
    the effect on the menu... Choose...
    Add to storyboard table.

    'Speed Up, Double' cuts the duration of half.

    "Slow Down, half ' double life.

    These effects can be added up to six times.

    If you need finer adjustment...
    the info may be useful:

    You can change the duration for each clip
    manually. Move your pointer autour the
    edge of an element until you see a double red
    arrow. Now, drag the double red arrow...
    you will see if show a ToolTip displays the duration
    train to change.

    Or... just to redo the project after changing
    the long-term: Tools / Options / Advanced
    tab.

  • Good for laptop - cannot change the ISP; keep returning to a previous provider

    Windows 7 laptop of my grandson, I'm migrating FIREFOX (excellent resource!) of my aging XP desktop. An existing Mozilla installation on the guarded device tries to connect to an ISP in Sydney (1000km) which kept out, I guess because the signal is too weak. Too far - on the Internet?

    Reinstalled my new ISP contact, reinstalled a fresh copy of Firefox, copied the old profile XP (just underneath the random string file name), but cannot change the fault. Firefox at startup tries to raise the old ISP (Sydney) and expires, and then allowing me to establish a manual connect with the ISP (my current) new.
    Perhaps a clue: in my Firefox troubleshooting info, change preferences, the browser start page is the address of 'old', with 'override mstone' ignore, what look like prints of registry entries, but I can't change all that - and maybe it's wise! An annoying secondary question: on arrival, the laptop listed no administrator user. So I am me came as an administrator, but I wonder if a past or current even Admin hidden could register (or other) entered resistant to change.

    Late discovery: the laptop is apparently infected with browser pirate btsearch.name. Search Google throws a series of removal procedures, and I'm now working through them.
    What Miss me?

    Sometimes a problem with Firefox can be a result of malware installed on your computer, you may not be aware of.

    You can try these free programs to search for malicious software that work with your existing anti-virus software:

    Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP, if you do not already have one.
