regexp: how to deal with different date formats?
the date comes as varchar2 with '-'and':' as separators for day part and part time respectively. but it may come with different formats such as1993-05-17
1993-05-17 13:04:23
1993-05-17 13:04
1993-05-17 13:4
1993-05-17 13:04
1993-05-17 13:4:2
1993-5-17-13:4:2
1993-5-7-13:4:2
and so on. date of final format should be ' YYYY-MM-DD HH24-SS'. is it possible to have an intelligent way to deal with different formats of date with separators above and convert the final using regexp format, so that it is compact and universal as possible with assumptions/examples above?
Thank you
As others have said, the smartest way is to keep your input in a format method and store your data in a date column.
But is a simple way to deal with this mess, without regexp,
with test as (
select '1993-05-17' d from dual
union all select '1993-05-17 13:04:23' from dual
union all select '1993-05-17 13:04' from dual
union all select '1993-05-17 13:4' from dual
union all select '1993-05-17 13:4:2' from dual
union all select '1993-5-17 13:4:2' from dual
union all select '1993-5-7 13:4:2' from dual
union all select '1993-05-17 1:4 PM' from dual
)
select d
, to_date( translate( d, 'xampAMP', 'x' )
, 'yyyy-mm-dd hh24:mi:ss'
)
+ case when instr( upper( d ), 'P' ) > 0 then 0.5 else 0 end cd
from test

Receive error message when calculating the two fields with different date format
I'm more familiar with SQL Server and Oracle, then after a search online without success, I ask here.
I use developer PL/SQL with DB Oracle 11g Release 11.2.0.2.0 Enterprise 64-bit
MyTable:
ID_Number VarChar2
Date of Date_Received
Select ID_Number,
Date_Received,
To_Date (substr (ID_Number, 1.6), "YYMMDD") SentDate,.
Date_Received - NumDays To_Date (substr (ID_Number, 1.6), "YYMMDD")
FROM MyTable
Where substr (ID_Number, 7.3) in ('ABC', 'ABD')
and length (Trim (translate ((substr (ID_Number, 1,6)), '0123456789',' '))) a null value
ID_Number Date_Received SentDate NumDays
131002ABC1654106 10/16/10/2013-2013 14 2
131004ABD8813899 4/12/2013-4/8/2013 4
131014ABD1844832 10/16/10/14 OF 2013-2013 2
Sometimes the first 6 characters in the ID_Number aren't the numbers and length (Trim (translate deletes records))
I want just the records where NumDays > 2
I tried to put the request in a subquery and using where NumDays > 2 outside. I also tried using the calculation directly in the Where clause. Without it in Where clause it works very well, with him in a place, I get the following error:
ORA-01931: Date format picture ends before converting all of the input string
I don't know how to put the two dates in the same format. I tried to declare the format without result. I don't understand how I can calculate in the selection, but do not use the same calculation in Where clause.
Thank you for your help.
Hello
SQL is a language to describe the desired results. How the system gets these results belongs to you don't have much say about which conditions will be applied when.
One place where you can control the order of things is a CASE expression. When you say
CASE
WHEN condition_1
THEN expression_1
END
You can be sure that expression_1 will be evaluated only when cond_1 is set to TRUE.
Try something like this:
WITH got_sent_date AS
(
SELECT id_number, date_received
CASE
WHEN the TRANSLATION (SUBSTR (id_number, 1, 6)
, 'x' 0123456789 '.
, 'x'
) IS NULL
THEN TO_DATE (SUBSTR (id_number, 1-6)
, "YYMMDD".
)
END AS sent_date
FROM MyTable
WHERE (id_number, 7, 3) SUBSTR ("ABC", "ABD")
)
SELECT id_number
date_received
sent_date
, date_received - sent_date AS num_days
OF got_sent_date
WHERE date_received > sent_date + 2
;
If you would care to post some sample data (CREATE TABLE and INSERT statements) and the results desired from this data, I was able to test this.
Of course, you'll still errors of execution if id_number starts with 6 digits, but they do not have to be valid, for example '131100' or '130229'. This is one of the reasons why the date information storage in VARCHAR2 columns are a bad idea. To work around this problem, see

How to deal with the change in scope
Dear,
No org by enforcement period. Consolidation of the CDA. CDA entry.
September, a company (X) is thrown into a perimeter (a-frame) and granted in a different consolidation perimeter (part B).
I need perform the following acts:
(A) CDA profit & loss of X, from September, must contribute to A scope results until December;
(B) BAT profits/losses of X in September, October and December, must contribute to the results of scope B until December.
(Operations under A) and B) can be automated? No idea how to do?
I don't have a script. I need only a generic description on how you did.
Thank you very much!
According to my experience, assuming that you create a new entity for X under parent B, the best thing to do in these situations is to simply manage it via a journal entry. You will write a day who would keep the CDA P & L (and in our cash flow of CDA case) result of X to the title of parent with equal and opposite impact hitting the new entity of X under B. You post this journal in Sep, Oct, Nov and dec and continue loading data for a YEAR to X under B.
However, if you simply drag & drop X under a new parent, I don't know how you deal with it.
Kind regards

Work with different raw formats?
Is the workflow even when working with different raw formats in Adobe Camera RAW? OR did each file requires different steps or processes?
Thank you.
Do you mean, for example, NAVE against CR2?
(Or, to use the vernacular style of the ESPN commentators, NAVE "verse" CR2.) ;-)
If so, there is no difference in how you work with them in Camera Raw. The differences are invisible to you, the user.

Apparently, my memory is almost full - no idea how to deal with not having a novice such am - sd card
Hi sixty.
It can also be a good idea to begin to transfer the content from your phone to a PC/Mac to help reduce the storage room.
It is a process usually easy, just plug the unit to a PC, on the phone screen select MTP mode when it appears.
Once finished, you just have to access the phone's internal memory and transfer pictures/videos from the DCIM folder.
Let us know if you need help in this kind of task.

Error blackBerry software - synchronization failed, impossible to deal with organizing data
I had a Q10 Blackberry last week. I downloaded and installed the PC of Blackberry link 1.2.2.13 version. Two-way sync USB worked fine. Now, all of a sudden, I get the error message "synchronization failed, impossible to deal with organizing data." I tried to reset the synchronization options, but not joy. Also tried to uninstall and reinstall the software Link 1.2.2.13, once again no joy. Any suggestions?
UPDATE: I spent 4 hours on the phone and the remote session with the help of Blackberry last night. After doing some troubleshooting to isolate the problem, determined that something on the device caused the problem of Outlook synchronization. One thing I've learned, it's that it can take a long time to synchronize and even though the progress of the screen may appear frozen, let it go until the end - sometimes it took 20-25 minutes, but eventually completed. Here's the process we went through - I would recommend appellant help BB and work with them to make sure you have not accidentally delete Outlook contacts and calendar of important information of your PC or BB device!.
(1) we tried an uninstall/reinstall the PC Link BB software and that did not fix the problem.
(2) to isolate the problem of synchronization. We first did a synchronization of 2 channels 'contacts' and 'calendar' and who was a failure. Then did a synchronization of only 2 channels 'contacts' and managed. Then did a synchronization of only 2-way 'calendar' and that was a failure - so the problem was linked to calendar data and something on the device has been the cause of the problem or corrupted.
(3) link BB allowing us to make a backup complete unit.
4) then decided to do a 'Wipe security' on the device of BB Q10 to erase all the data and settings and return to a clean boot device configuration. I was nervous about it - make double sure that Outlook all contacts and calendar data on the device and the PC are completely backed up in case something bad happens. Nothing serious happened, but I was gald, we made the backup!
(5) has the 'Security Wipe' feature (on the device, the settings > Security and privacy > wipe security) and phone rebooted without problems (takes a while to do).
(6) then used link BB to do a sync test 1 channel 'contacts and calendar' from PC to device. It worked without problem.
(7) we then used BB link do a "restore" full backup of device, as we did in step 3 above. It takes a while to make and was a success.
(8) once the restoration of the aircraft was complete, BB link configured to perform a synchronization of 2 channels of the two 'contacts' and 'calendar '. Does the synchronization and was a success. Did a test by adding the new entry of the calendar on PC and did another 2-way sync - all worked very well. Seems that the problem has been corrected, but will follow in the coming days.
Lessons learned:
(1) If you have a lot of Outlook contacts and calendar entries, the synchronization may take a long time. Be patient and let it run - even if it seems stuck, etc!
(2) save all Outlook data on the device and the PC to make sure that you have a backup something bad happened during troubleshooting. We had not something bad happens, but I was gald we made a backup anyway.
(2) call BB help - support person, I worked with was fabulous, even if it took some time to work through a patch.

How to deal with operating system windows 8.1 and apps on usb device
Hi, I have a laptop Lenovo G505. Windows 8 64-bit was preinstalled in it. Later, I upgraded to 8.1. Laptop is almost 9 months and still under warranty. Since a few days, built Lenovo solution Center alert this analysis of hardware detected failures in one or more devices. On suggestion of Lenovo, I ran hdtune pro app in my machine and it also detected 3 hard drive errors. As my machine is under warranty, Lenovo is ready to replace my hard drive with a new one. But they say that it is the responsibility of the customer to return the windows 8.1 operating system and install in the new drive and their liability is limited to the replacement of the hard disk only. I am not computer savvy and I request concerned to guide me how to deal with operating system windows 8.1 on external media like USB, DVD, and install in the new drive. I also installed a number of apps and paid games. Therefore, I would like to resume these games also files so that I need not buy again. Assistance in this regard is required.
Hello Mohan,
Thanks for posting your query in Microsoft Community Forum.
I can of course understand the situation and will be happy to help with your query.
Let me ask you;
- You have the key product for Windows 8 or 8.1?
You can create an installation media (DVD/USB) for Windows 8.1 and re-install when you want. However, in order to create an installation media for Windows 8.1, you need the product key. If you don't have the product key for Windows 8.1, you can not create installation media.
You can create the installation media for Windows 8 by using the product key Windows 8 If you have. In this case, install you Windows 8 first and then go to Windows 8.1 through store.
As far as your paid apps (purchased by store) are concerned, you should be able to install them as soon as you sign in with the same Microsoft Account where apps were purchased.
You can see the steps indicated by Ronnie Vernon replied on 24 December2013, re - install paid apps.
You can follow the steps below to create installation media.
- Run the program Windows 8.1 configuration or installation of Windows 8 (depending on the availability of the product key for the specific operating system.
When you are prompted to run or save the file, choose run
When you are prompted to enter a product key, enter the 25-character product key, that you received when you purchased Windows 8.1 (or Windows 8).
When you are prompted to install Windows 8.1 (or Windows 8), select install by creating media and then click Next.
Select the type of media you want to use: either a Flash DRIVE or a DVD.
To create a USB flash drive
Click on the USB flash drive.
Plug the USB key into a USB port on your PC.
When you are prompted, select the USB key that you want to use, and then click Next.
If you have files on the USB flash drive, it will remove them.
To create a DVD
Click on the ISO file , and then select the location where to save the ISO file.
Insert a blank recordable DVD into your DVD drive.
Burn the ISO of the DVD file using Windows disc Image burner, or another program DVD burning.
Note: Ensure that the USB or DVD key that you use has nothing else stored on it and has a sufficient free space to download the Windows 8.1 Installer: about 2.3 GB for the 64-bit version.
You can also read the article below to create a USB stick recovery.
Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.
Thank you.

How to deal with the JPEG image data
I have a XML element defined by the user who provides a JPEG image.
Is it possible to directly use this JPEG information in my PDF? (would be great - but seems to want)
or I (seems more likley to me) should first write the JPEG data to a file and then load into my PDF file.
If you can point me to a pretty good example of how to do this, however, it is accomplished, or can explain it in this forum
I should be grateful if you would, and I think that others might be out a lot as well.
Thank you
See you soon
For XFA-based PDF files, you can simply read the XFA specification to learn how to integrate the JPEG data in this grammar. But it's easy enough...

Play with the date format TO_CHAR

How can I place an explicit function TO_CHAR date?
Oracle converts implicitly your string to a date so that it can convert it to a string using your to_char function. Implicit conversion is based on your NLS_DATE_FORMAT settings, but you can never count on these implicit conversions.
You can be...
SQL> select to_char(to_date('20-DEC-10','DD-MON-RR'),'dl') from dual; TO_CHAR(TO_DATE('20-DEC-10' --------------------------- Monday 20 December 2010
or
SQL> select to_char(date '2010-12-20','dl') from dual; TO_CHAR(DATE'2010-12-20 ----------------------- Monday 20 December 2010
Note that this one used Oracle fixed-date internal format YYYY-MM-DD, so if ever you use this method, you must specify the date string in this format. It also only deals with dates, not the component "hour".
