Oracle Alert: Access before and after update values of a table column
We have a requirement where a notification needs to be sent when 'END_DATE' attribute (column in a table X) is set, in an Oracle Applications form.
I have defined an Event based Oracle Alert which fires 'On Update' of the table X.
Could anyone please let me know as how to access the value of 'END_DATE' before and after update (i.e :new.END_DATE and :old.END_DATE) in the sql query of the alert.
The need to use the before update and after update values of the attribute 'END_DATE' is that if we add the condition END_DATE is not null, the alert is sent even if any other attrbutes are updated in the Oracle form which is not the intended behavior.
Appreciate any help.
Thanks
Hi
use selectionlistener for your first table then add clientlistener and serverlistener so that you will get the rows on click in back bean.
then get second table vo and and create and add row for that view object. add partial target to refresh your second table from back bean.
on click of save call commit operation.

Repairing permissions before and after updating software
What is the reason to repair permissions before and after updating software? This may sound like a stupid question to many of you, but I am new to computers and I am trying to learn how and why of some of the things of my PowerBook. I installed some updates without repairing permissions. Did I install some software updates the wrong way? Thank you.
This is a topic which will draw as many emphatic for and against responses as overnight shut down or not, defrag or not, optimise or not, and so on.
I agree with Neil. I believe that OS X has progressed sufficiently that repair permissions has become redundant and so I do not do it on any regular basis.
Some folk may refer you to an Apple Support Article 303602. That Article in its 4 May 2006 version, titled "Top 10 Tips to Keep Your Mac in Top Form" suggested Repair Permissions should be done "after upgrading or installing new software". The Article was however revised on 15 May 2006 to be titled "Top Tips to Keep Your Mac in Top Form" and the item on Repair Permissions [along with two other recommended maintenance tips] was removed. It is my view that the conclusion to be drawn here is that Apple no longer considers Repair Permissions to be a required maintenance procedure.
Many users have adopted a "Repair Permissions" mantra for a cure-all over several years. I dropped it sometime in 10.3.
But, to each his own.

Possible to get JComboBox before and after chaged value?
Hi,
I have a JComboBox... whenever the JComboBox value change is it possible to get the before and after changed value? For example:
Let says the JComboBox is showing "One" and the user change it to "Three" after the user chged... I want to System.out.println before chged value ("One") and aft chged value ("Three")
I tried:
put in some code in the itemStateChanged() method... but no success...
Can someone pls provide some pointer or sample code...
Thank you for your time...Ok, I lost half a day on this (novice problem), but I arranjed a solution that resolve the problem totally. There is the code:
YourComboBox.addFocusListener(new java.awt.event.FocusAdapter()
int aux_selected;
// if YourComboBox gains Focus
public void focusGained(java.awt.event.FocusEvent fe)
// get index value of selected element
aux_selected= YourComboBox.getSelectedIndex();
// create a variable for storing de ItemListener
ComboBListener = new java.awt.event.ItemListener() {
public void itemStateChanged(java.awt.event.ItemEvent e)
if(e.getStateChange()==java.awt.event.ItemEvent.SELECTED)
// compares the selected value with the old one
if (aux_selected!=YourComboBox.getSelectedIndex())
System.out.println("ComboBox Changed !");
// add the variable Listener to your Combo
YourComboBox.addItemListener(ComboBListener);
// if focus is lost
public void focusLost(java.awt.event.FocusEvent fe)
// remove the itemListener from the combobox
YourComboBox.removeItemListener(ComboBListener);
//Put the Listener variable outside
private java.awt.event.ItemListener ComboBListener; //----------------------------------------------------------------------------------------------------
You only have to change YourComboBox by the name of the combobox.

Triggers before and after update
Hi
I would like to add triggers before and after update for the following code. I would be thankful if someone give some guidance
update per_all_people_f a
set start_date = (select min(effective_start_date)
from per_all_people_f a1
where a1.person_id = a.person_id)
where person_id in (1114,115);Thanks
annaHi
I was unable to answer you. I agree with Peter . Also i want to add
that in HRMS you should check what triggers are already on that table and be carefull with creating your own one. With your own trigger you can influence on some application logic you know.
( And i hope that is a table first of all :) - but as i know _F at the end of table name means table )

Error uploading file to web before and after updating
Hi,
I'm running adobe muse on a mac 2013 yosemite. I changed from the original version of adobe muse to the 2014.2 version, just to let you all know.
Earlier today, I woke up and one of my two websites I've created in the original version of adobe muse had lost the information required to upload to FTP Host. I retyped in my information, and it started to upload my website. Eventually it hit the 61% mark, and said that it was "connecting to the FTP host" for a really, really long time. I waited about 20 minutes- nothing happened. So I then decided to update adobe muse to the 2014.2 version.
After updating, I tried uploading my site to the web again. I put in virtually the same information as before, and now I'm getting an error message saying "Could not sign in. Check your network connection and try again. If this problem persists, try again later."
Can anybody help me here? My website is hosted by GoDaddy.com, just to let you know.
Thanks in advance,
GavinMuse 2014.3 was released last week , please tr y to update Muse and then check.
Thanks,

Cannot connect to itunes store before and after update ios 8.2, What can i do ?
I updated to iOS 8.2 about 2 hours age and I get an error saying "cannot connect to iTunes Store" every time I try to update existing apps or download new apps. I restarted my phone, disconnected from wifi, reconnected to wifi...nothing is working. Under iTunes & App Store settings, I signed out and now get the "cannot connect to iTunes Store" message when trying to sign back in. I know my Apple ID and password are correct.
Based on the numerous posts regarding iTunes and the App Store, there appears to be an issue at Apple's end. Although Apple has not provided any indication on the cloud status page.
Do not change your settings. -
IPad 2 cannot connect to Wifi before and after updating PLEASE HELP
i have been using iOS 5.1.1 till today.. the connection to wifi stopped working.. it slowly faded away and today i woke up and could not connect to My wifi at all, i have decided to update my iPad to iOS 7.0.4 but the problem is there
what should i doo ??It could be a problem with your WiFi router or your iPad.
If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPad. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
First, test your iPad on some other WiFi networks: a friends, Starbucks, Barnes & Noble, etc.
If it works well there then the problem is probably with your network. Try restarting your WiFi router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
If your iPad does not function well on other networks it possibly has a hardware problem. You could try Settings > General > Reset > Reset Network Settings to see if that corrects the problem. If not, contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPad is bad.
If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

Before update and after Update trigger
Hi,
I am following the below approach to overcome ORA-04091: table XXXX is mutating error.
1. In the after update row level trigger i am capturing rowids of changed rows into a table type (of type rowid) defined in a package.
2. In the after update statement level trigger i am using the data from the table type ( that got populated in the first step) to do my work.
3. In the before update statement level trigger i am resetting the table type defined in the package.
Now, can the below situation occur causing the system to fail
1. A Update to the table occurred causing the before update statement level trigger to fire and reset the table type.
2. After that row level after update trigger gets executed and captures the required data.
3. Now before the after update statement level trigger gets executed a new update to the table happened ( to some other row as multiple users are using the application) causing the
before update statement level to fire and erase the data from the table type?
I want to know if above situation can occur or is the execution or before and after update triggers atomic?
Thanks for helping.
TIA
HarshaA collection in a package is local to the session. And a given session can be processing one SQL statement at a time. So any concurrent updates would be happening in a different session with a different logical collection.
You may encounter problems if your session is trying to update the same rows that other sessions are trying to update (whether via the original update statement or via the updates issued by the trigger). You could encounter performance problems because of row level locks or you could encounter deadlocks. But your session's collection won't be initialized by some other session's actions (other than DDL that replaced the package itself).

Before and After insert or update rowcount
Hi
I have several extract objects procs which are calling various build objects procs which in turn are inserting or updating the tables...now when i run these objects sometimes i get no errors and everything seems to be running perfectly but the tables do not get updated ? now what i am trying to achieve here is get some kind of summary where i can see the before and after rowcount..for that i have created a table of every extract object proc and another table with the coressponding tables being updated by tht proc...can anyone pls tell me how should i look into these procs and how do i get the rowcount for a particular table before and after the procedure was run ?
Thanks a lot in advanceHi,
On which version of RDBMS are you working , because if you're on 10g then just enable auditing or even FGA on the tables were you want to see the changes,
Then query the DBA-AUDIT (not sure of the name anymore) view.
If not then create a audit package yourself.
something like
create or replace package pck$audit as
procedure prc$check_tablecount(p_tablename IN VARCHAR2, p_status IN VARCHAR2);
end;
create or replace package body pck$audit as
procedure prc$check_tablecount(p_tablename IN VARCHAR2,p_status IN VARCHAR2) IS
sqlstr VARCHAR2(100);
v_count NUMBER;
begin
sqlstr := 'SELECT COUNT(*) FROM '||p_tablename;
EXECUTE IMMEDIATE sqlstr into v_count; --could by 'using v_count' check syntax for this
INSERT INTO audit_table(table_name,total_count,status,time_stamp)
VALUES(p_tablename,v_count,p_status,SYSTIMESTAMP);
COMMIT;
end;
end;
you can elaborate on this creating additional procedure checking differences in total_count on same table at same time.
Now call this procedure before starting your insert-delete- on your table make sure you put the parameters correct eg p_status => 'begin procedure'
and call it again after your commit in your procedure.
Hope this helps you out

Everyone: This time repair your permissions before and after 10.4.8 update
Hello All,
Just a reminder for all those who are updating to OS 10.4.8.
While many people do ignore all the recommendations that we provide and still come through fine, please do consider observing the following to minimize your problems.
To insure the best chance of success, please consider downloading the Combo Updater for your computer instead of using Software update.
For PowerPC Mac's, this would be:
http://www.apple.com/support/downloads/macosx1048comboupdateppc.html
For Intel Macs, this would be:
http://www.apple.com/support/downloads/macosx1048comboupdateintel.html
The benefit of using the Combo Updater, is that it replaces all system files that have been changed since the last major release (in this case since 10.4.0).
So, if you have any system files that have become corrupted, the Combo Updater will very likely over-write those, and spare you the headaches that come from updating an operating system that has problems that just haven't come to the surface yet.
In many cases, you can have problems that have not come to the surface, and the "Delta" or Software update method will bring them out to bite you. The reason for this, is because the Delta / Software Update version only changes files that have changed since 10.4.7. And, it works more in a "patch" fashion. So, if there is a problem in one of the files being patched, then the update will cause you some major headaches.
Going with the larger "Combo" update over-writes almost all the System files with clean versions instead of just making patches. So, it is frequently much more successful.
Now, with that said, before you update, you should make sure your permissions are all set properly. If your permissions are wrong, then your update will likely have trouble.
So, go into "Disk Utility" in the Applications --> Utilities folder and repair your permissions.
Start by selecting your hard drive on the left window of Disk Utility. Then, go down and click on the "Repair Permissions" button. Once it's completed, then exit Disk Utility.
Now, it is also extremely important to make sure all running programs are closed before you install any system update. So, go ahead and restart your computer.
Restarting will make sure that all programs are closed, and that nothing weird is stuck in memory before you install.
If you have anti-virus programs running, then disable or deactivate them first (you don't want them interpreting this as unauthorized modification or it might prevent certain files from being updated).
Now, with your computer freshly restarted, install the Combo updater you downloaded.
When prompted, click on the "Restart" button when prompted.
Now, the computer will startup, but sit at the spinning wheel for several minutes. It will eventually restart again on it's own. And, finally, it will start-up all the way and you'll be back at your desktop.
Now, immediately go back to Disk Utility and repair permissions as you did in the previous step. You will likely see several permissions that have been repaired. In my case, I had dozens of CoreAudio, Widgets, and other permissions that needed repair. Once permissions have been repaired, go ahead and restart one last time. This makes sure that everything is set and then cleaned-up.
Once it reboots, begin using it and enjoy.
Now, this may sound like a lot. But, it really is simple. It just reads like a lot of stuff.
And, of course, you are free to ignore this and just install it however you like. Many people have their own ideas here. And, many people say you don't have to do anything to prepare. But, for those that have had huge problems in the past, these extra steps will usually save you the major headaches that tons of people inevitably have with every new update.
Anyway, I hope this helps to save at least a few of you any problems. If you don't agree with the ideas above, just ignore it and do as you like.
But, if you want a little extra piece-of-mind and a better chance at success, then please consider exercising this extra caution.
And, for the record, I have updated my machines to 10.4.8 (within minutes of the update being available) and it is working perfectly smooth on my systems.
I hope you find this helpful.mhunter, thanks and good that you take the time and effort again to remind everyone that it does take an effort to do a major OS update, to ensure maximum stability.
So far my 10.4.8 Update is a-okay, and I have had many trouble-free updates since installing 10.4
I too practice rigourously and "religiously" before and after an OS or Security Update, but I normally use Software Update, equally successful:
1. Before Startup, UNPLUG all external devices, left only keyboard, mouse and internet connection, unless they are all wireless.
2. Startup, disable NAV if any, Repair Disk Permission. Restart again, Repair Permission again.
3. Do Software Update
4. Restart, Repair Permission
5. Shutdown, plug everything back
6. Startup Mac, use Mac
So far these steps have been keeping all my macs both at home and at work very very stable and healthy.
Maybe, just maybe if everyone here, all mac users were to follow these steps, yes they can be a hassle, yes they can take up some time, but then there will be less less complains and "blasts" at Apple, just because perhaps themselves have been too careless or negligance in performing updates.

I'm unable to update my apps or download new apps to my Iphone. When I try I get a message "An unknown error has occurred". It was happening before and after the last OS upgrade. I've done a hard reboot with no effect. Any suggestions???
Have either of you had any luck with this issue. It began happening to me today when I was trying to purchase music on iTunes. I have purchased music and games in the past and have had no problem. Any help would be appreciated.

How to compare value before and after
hi,
one of the queried Values is the number of defective frames.Here, this value is compared with a previously sampled value
If now (after 10 s) this value is bigger than previous one ,then It saves new value otherwise loop will be continue.If again after (10s) the new value is bigger than previous new value then again saves this new point.how can i comapre value before and after?thanks.
TadhikaDo you know what a shift register is? It preserves a value from one loop iteration to the next. Please read the LabVIEW Help on shift registers. There's is also a simple example that ships with LabVIEW that will give you the basic idea (Help -> Find Examples).
You can also use a Feedback Node in lieu of a shift register. Same concept, different implementation. -
Counting values before and after an interval
I posted this awhile back but I'm back to trying to solve the problem (didn't solve it), so apologies if that is bad etiquette! This forum has been so helpful though I thought I would try again:
design/methodology question
The short of it is I have a table with calls that happened, all have a start and end time.
I want to take 1 min intervals over a given hour (say, 12-1pm) and (the part I need help with) count all calls that happened before and after that interval.
That is to say, all calls that were 'active' during that interval (consider if I call started at 11:59 am and ended at 12:05) would need to be counted for the 12:00, 12:01, 12:02, 12:03, 12:04, and 12:05 intervals.
So what I'm trying to construct is an SQL query that uses a 'variable' in this case (I think).
That is, so I can saw 'where start_time < min_interval' and where 'end_time is > min_interval' and count those records to my total.
But I'm at a loss on how to pull this off!
Thoughts?If a call began at 15:01:01 and ended at 15:01:59, was it active at 15:01? Was it active at 15:02? Both? Neither?Is only active at 15:01.
Do you need 4 separate numbers, or do you need 1 number, which is the total of these 4?I need 1 number which is the math formula (using the number above)
1 + 2 - 3 + 4
Oracle version is 10.2.0.4.0
I will work on learning the CREATE TABLE and INSERT statements, as well as, the WITH one.
Is the point of submitting those to understand the data set being worked with?
Here is my attempt...
Consider the following:
WITH my_call AS
SELECT 1 AS call_id , to_date('10-may-2011 12:00:17'
, 'dd-mon-yyyy hh24:mi:ss'

)then, to solve #1 (calls that started in each minute):
select
to_char(new_time(trunc(start_time, 'hh24') + (trunc(to_char(start_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') as "Start Time",
count(*) as "Start Time Count"
from
my_call
group by
to_char(new_time(trunc(start_time, 'hh24') + (trunc(to_char(start_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi')
order by
to_char(new_time(trunc(start_time, 'hh24') + (trunc(to_char(start_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi');would yield the following output (consider I am converting to GMT in this example):
07:00 2
07:01 2
07:02 2
07:03 2To solve 2, calls with end_time, I do the following:
select
to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') as "End Time",

order by
to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi');which gives us:
07:01 2
07:03 1
07:04 3
07:05 1
07:08 1# 3 (calls that started and ended in the same minute) is:
select
to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') as "End Time",
count(*) as "End Time Count"
from
my_call
where
to_char(new_time(trunc(start_time, 'hh24') + (trunc(to_char(start_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') = to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi')
GROUP BY to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi')

to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi');which gives us:
07:01 1Now, given the small data set (which, as a side note, I can see a little, now, why the WITH statement here is useful and important!) we know the final output should be
(EXPECTED RESULT WHEN WE ARE DONE):
07:00 2
07:01 4

07:04 5

07:06 1
07:07 1
07:08 1So what I am posting this forum is help in calculating #4 - calls that had a start time (trunc'd to the minute) before the minute interval and an end_time after.
Something like this:
select
to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') as "End Time",
count(*) as "End Time Count"
from
my_call
where
to_char(new_time(trunc(start_time, 'hh24') + (trunc(to_char(start_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') < minute_interval and
to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi') > minute_interval
GROUP BY to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi')
order by
to_char(new_time(trunc(end_time, 'hh24') + (trunc(to_char(end_time, 'mi')/1)*1)/24/60, 'GMT', 'CDT'), 'hh24:mi');where the expected output would be:
07:00 0
07:01 1
