Spaces and 'is numeric' validation.

Hello everyone,
I'm using a simple application and in one field, i have a ' is numeric ' validation on a text field item.
Everything works fine except that when i enter a space ' ' , the validation does not stop the request and i end up with
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
I tried using Regex with something like : ^\d+$ and the space was still considered valid.
I know i can TRIM every single numeric field.. however, i was wondering if there was a more " elegant " solution and, most importantly, one i could apply to an entire workspace.
Thanks, Will
EDIT :
I am running APEX 3.0.1

Hi Will,
What I prefer to do for validation is selecting the validation type "PL/SQL returning error message".
Then, I create a package called let say APEX_VALIDATIONS_PKG. This package contains all my valiations process. (i.e. : IS_NUMERIC, IS_NULL, IS_NOT_NULL, IS_DATE,...)
If you do this, you can determine what is a numeric, what is a null value (i.e.: having "-1","0","null","%null%", etc is a null value).
Hope this help.

HT204120 My iPhone 5s is stuck with 3948 photos (shown on the iTunes storage bar) on and I can not find a way to delete them all! It's very annoying as it takes up 6.54 GB of space and leaves me no room to add films, music...etc on to it. Please help me!!

My iPhone 5s (16GB) is stuck with 3948 photos (shown on the iTunes storage bar) on and I can not find a way to delete them all! It's very annoying as it takes up 6.54 GB of space and leaves me no room to add films, music...etc on to it. Please help me!!! I have already tried the numerous articles Apple have sent my way and I am still having no luck.I'd be eternally grateful if anyone could find a solution for me as this has been a problem for almost a year. Thank you.

If they were put there via iTunes sync process, then simply untick the Music box before syncing again.

Color Space and Bit Depth - What Makes Sense?

I'm constantly confused about which color space and bit depth to choose for various things.
Examples:
- Does it make any sense to choose sRGB and 16-bits? (I thought sRGB was 8-bit by nature, no?)
- Likewise for AdobeRGB - are the upper 8-bits empty if you use 16-bits?
- What is the relationship between Nikon AdobeWide RGB, and AdobeRGB? - if a software supports one, will it support the other?
- ProPhoto/8-bits - is there ever a reason?...
I could go on, but I think you get the idea...
Any help?
Rob

So, it does not really make sense to use ProPhoto/8 for output (or for anything else I guess(?)), even if its supported, since it is optimized for an extended gamut, and if your output device does not encompass the gamut, then you've lost something since your bits will be spread thinner in the "most important" colors.
Correct, you do not want to do prophotoRGB 8bit anything. It is very easy to get posterization with it. Coincidentally, if you print from Lightroom and let the driver manage and do not check 16-bit output, Lightroom outputs prophotoRGB 8bits to the driver. This is rather annoying as it is very easy to get posterizaed prints this way.
It seems that AdobeRGB has been optimized more for "important" colors and so if you have to scrunch down into an 8-bit jpeg, then its the best choice if supported - same would hold true for an 8-bit tif I would think (?)
Correct on both counts. If there is color management and you go 8 bits adobeRGB is a good choice. This is only really true for print targets though as adobeRGB encompasses more of a typical CMYK gamut than sRGB. For display targets such as the web you will be better off always using sRGB as 99% of displays are closer to that and so you don't gain anything. Also, 80% of web browsers is still not color managed.
On a theoretical note: I still don't understand why if image data is 12 or 14 bits and the image format uses 16 bits, why there has to be a boundary drawn around the gamut representation. But for practical purposes, maybe it doesn't really matter.
Do realitze hat the original image in 12 to 14 bits is in linear gamma as that is how the sensor reacts to light. However formats for display are always gamma corrected for efficiency, because the human eye reacts non-linearly to light and because typical displays have a gamma powerlaw response of brightness/darkness. Lightroom internally uses a 16-bit linear space. This is more bits than the 12 or 14 bits simply to avoid aliasing errors and other numeric errors. Similarly the working space is chosen larger than the gamut cameras can capture in order to have some overhead that allows for flexibility and avoids blowing out in intermediary stages of the processing pipeline. You have to choose something and so prophotoRGB, one of the widest RGB spaces out there is used. This is explained quite well here.
- Is there any reason not to standardize 8-bit tif or jpg files on AdobeRGB and leave sRGB for the rare cases when legacy support is more important than color integrity?
Actually legacy issues are rampant. Even now, color management is very spotty, even in shops oriented towards professionals. Also, arguably the largest destination for digital file output, the web, is almost not color managed. sRGB remains king unfortunately. It could be so much better if everybody used Safari or Firefox, but that clearly is not the case yet.
- And standardize 16 bit formats on the widest gamut supported by whatever you're doing with it? - ProPhoto for editing, and maybe whatever gamut is recommended by other software or hardware vendors for special purposes...
Yes, if you go 16 bits, there is no point not doing prophotoRGB.
Personally, all my web photos are presented through Flash, which supports AdobeRGB even if the browser proper does not. So I don't have legacy browsers to worry about myself.
Flash only supports non-sRGB images if you have enabled it yourself. NONE of the included flash templates in Lightroom for example enable it.
that IE was the last browser to be upgraded for colorspace support (ie9)
AFAIK (I don't do windows, so I have not tested IE9 myself), IE 9 still is not color managed. The only thing it does is when it encounters a jpeg with a ICC profile different than sRGB is translate it to sRGB and send that to the monitor without using the monitor profile. That is not color management at all. It is rather useless and completely contrary to what Microsoft themselves said many years ago well behaved browsers should do. It is also contrary to all of Windows 7 included utilities for image display. Really weird! Wide gamut displays are becoming more and more prevalent and this is backwards. Even if IE9 does this halfassed color transform, you can still not standardize on adobeRGB as it will take years for IE versions to really switch over. Many people still use IE6 and only recently has my website's access switched over to mostly IE8. Don't hold your breath for this.
Amazingly, in 2010, the only correctly color managed browser on windows is still Safari as Firefox doesn't support v4 icc monitor profiles and IE9 doesn't color manage at all except for translating between spaces to sRGB which is not very useful. Chrome can be made to color manage on windows apparently with a command line switch. On Macs the situation is better since Safari, Chrome (only correctly on 10.6) and Firefox (only with v2 ICC monitor profiles) all color manage. However, on mobile platforms, not a single browser color manages!

Ignoring spaces and non-alphanumeric characters

I need some help with this program im working on. It's testing to see whether words are palindromes or not. The trouble is, i need to make the program ignore spaces and puncuation. Does anyone know of a command to do this, or a command where i can list all the common types of puncuation and get the program to ignore them.
Thanks

you can use regular expressions (regex) for this. I'm not very experienced with regex (though I admit I should become familiar with it ;)), so for more information check out Sun's regex tutorial and regular-expressions.info.
if you're not interested in regex (or if you don't have access to a 1.4+ SDK), you can just use ASCII filtering to achieve this (see this ASCII table for basic ASCII values). Basically, you're only going to accept A-Z and 0-9 characters (if I understand your question correctly). This means the only ASCII values you want to accept is 48-57, 65-90, and 97-122. You can use a simple boolean method to check if a character is valid. Something like this should work:
public boolean valid(char c) {
     int x = (int)c; // ascii value of c
     return ((x >= 48 && x <= 57) || (x >= 65 && x <= 90) || (x >= 97 && x <= 122));
}Use this method on every character of the String you want to process. So to validate an entire String you can use a method like this:
public boolean valid(String s) {
     for (int j = 0;j < s.length();j++) {
          if (!valid(s.charAt(j))) {
               return false;
     return true;
}Beware though that this is considerably slower than using regular expressions. Also I didn't compile this example so there might be a small mistake you'll have to fix.

What is difference between table space and shchema

what is difference between table space and shchema ?

784633 wrote:
so each user has it own space of tables - schema ?yes, but let's clarify a bit ....
The "schema" is the collection of all objects owned by a particular user. So if user SCOTT creates two tables, EMP and DEPT, and a view EMP_RPT, and a procedure GET_MY_EMP, those objects (tables, views, procedures) collectively make up the SCOTT schema.
Those objects will be physically stored in a tablespace.
A tablespace is a named collection of data files. So tablespace USERS will be made up of one or more data files. A specific datafile can belong to one and only one tablespace. If a tablespace has more than one data file, oracle will manage those files as a collection invisible to the application - much like the OS or disk subsystem handles striping across multiple physical disks.
A specific object in the SCOTT schema can exist in only one tablespace, but not all objects of the schema have to be in the same tablespace. Likewise a tablespace can contain objects from multiple schemas.
and can one user to access tables of other users?As others have said - FRED can access tables belonging to SCOTT as long has SCOTT has granted that access to FRED.

PreparedStatement space and empty String

Hi, I have this problem:
PreparedStatement bookedQtyPS = null;
String qry="SELECT * from djwsearch where djwitem=?;
bookedQtyPS = conn.prepareStatement(qry);
if(item.equals(""){ //item is an empty String
bookedQtyPS.setString(1," "); // I set space instead of empty String
}else{
bookedQtyPS.setString(1,item);
My problem is that I need to set space insteadOf empty String, but I think that I can not use PreparedStatement to do this. I have performance problems (my query is much more complicated than this one) so I choose PreparedStatement and not Statement.
How can I do? Is this bug solved using PreparedStatement?
Thanks.

you can do it with the help of PreparedStatement.
Here the type of field(djwitem) and setmethod is should be match..i mean if the type of ur field is String then you need to use the setSting method.
you can do one thing specify one string variable.
String space=" ";
and now put this sapce variable at the second parameter of setString method.

though I have sufficent memory space, and other internet based functions are running...

Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

However, since it works with other networks that really suggests a problem with your network.

As posted about a dozen times every day, try the offline installer from http://get.adobe.com/reader/enterprise/

I recently deleted a partition on my mac that was intended to install windows. Now it is just blank space. I attempt to resize my Macintosh HD partition to cover entire hard drive space and hit apply but nothing happens (disk utility). Any ideas?

I have a few problems...
I wanted to make a partition to install windows, I tried to use bootcamp 5 where it wanted to partition and install windows at the same time. I do not have a cd of windows but instead had it on a flash drive. Bootcamp couldn't find it. Instead I was reading forums and found that there was another way to install windows by partioning your harddrive using the disk utility, downloading the bootcamp drivers, and installing rEFIt (an app that when starting the compouter a menu would come up to boot windows from the flashdrive). I try that and the windows install screen gets me to the point where I pick a partition. I attempt to pick the partitioned drive but a message comes up telling me that "this is of the GPT partition style" and windows cannot be installed on the drive.
So now I went back to disk utility and deleted the partition but there is still blank space. I wanted to retry and install windows through bootcamp (somehow) but a message comes up that there cannot be any partitions or that a partition must be created using bootcamp. SO i keep trying to drag the partition over the blank space and hit apply but nothing happens.
By the way I was trying to install windows 8 pro, some forums would say that you cant install win8 however I found others that said you could. How do I fix my partition and how do I use bootcamp to install windows (preferrably 8)?

Csound1 What Ive been trying to explain is that I have been running bootcamp, I open the app where the first screen is the introduction, i hit continue, the first time I select "download the latest windows support software fromm Apple" then I return and instead select "Install Windows 7." Then hit continue. The third screen is where I "Create a Partition for Windows" I set Windows to 80 gigs then hit INSTALL. As stated before Bootcamp cannot find the install drivers saying "The installer disc could not be found." My windows software is on a USB drive not a disc, I tried using a virtual disc reader to make it appear that the windows software was running on a disc, still no luck. What I would like to know is how to install windows on bootcamp.

After upgrading to 8.1 Pro from 8.0 Pro, my Storage Spaces and Storage Pool are all gone.

Under 8.0 I had three 4-terabyte drives set up as a Storage Pool in Storage Spaces. I had five storage-space drives using this pool I had
been using them for months with no problems. After upgrading to 8.1 ( which gave no errors ) the drives no longer exist. Going into "Storage Spaces" in the control panel, I do not see my existing storage pool or storage drives. I'm prompted
to create a new Pool and Storage Spaces. If I click the "Create Pool" it does not list the three drives I used previously as available to add.
Device Manager shows all three drives as present and OK.
Disk Management shows Disks 0,1,2,6. The gap in between 2 and 6 is where the 3,4,5 storage spaces drives were.
Nothing helpful in the event log or the services.
I've downloaded the ReclaiMe Storage Spaces recovery tool and it sees all of my logical drives with a "good" prognosis for recovery. I've not gone down that road yet though because it requires separate physical drives to copy everything to
and they want $299 for the privilege.
Does anyone have any ideas? I'm thinking of doing a fresh 8.1 install to another drive to see if it can see it or reinstalling 8.1 to the existing drive in the hope that it will just suddenly work. Or possibly going back to 8.0.
Thanks for your help!
Steve

Hi,
“For parity spaces you must backup your data and delete the parity spaces. At this point, you may upgrade or perform a clean install of Windows 8. After the upgrade or clean installation is complete, you may recreate parity spaces and
restore your data.”

Keep white spaces and carriage returns?

I'm viewing a column -VARCHAR2(4000)- in a standard report column.
The column value contains white spaces and carriage returns.
I put "white-space:pre;" in CSS Style, but it still skips carriage returns...
What can I do to view white spaces and carriage returns?
I'm using apex 3.0 and IE 7.
Saad.

I'm using apex 3.0 and IE 7.There's your problem...
IE6 (and, since there don't seem to be any docs saying anything different, presumably IE7) don't support white-space: pre in quirks mode. Don't ask me why - probably in one of MS efforts to "not break the web".
All the APEX built-in templates are rendered in quirks mode as they don't supply complete DOCTYPEs. If you are using a standard APEX template or a custom template without a complete DOCTYPE declaration you are probably seeing this quirks behaviour.
It looks like this will change in IE8.

Whatever you read about iTunes is wrong unless you're actually referring to feature movies, not videos. Videos, apps, music and iBooks you can re-download:
http://support.apple.com/kb/ht2519
Download to your computer and then sync to your iPod touch whatever will fit.
And no, I can't say with certainty that they won't give you a refund, but it's unlikely. The most probable outcome, if you do indeed mean movies, not TV shows or other videos, is that they would set up an additional download. For other content they'll probably just direct you to the same instructions on re-downloading I just posted.

Not possible. Safari won't download and save a Zip file. You either had to use a 3rd party app, or as wjosten suggests, your phone is jailbroken. If the former, you'll need to use that app to find it. If the latter, you'll have to look elsewhere for assistance.
