looking for all when setting = null
Hi guys, im having a little problem with the settings on my report. When I enter a value to search it works fine, but when I do not enter a value in my parameter (because I want it to look for all) it won't bring back all records where the field is null.for example suffice it to say I'm looking for a person with the name thomas it will work very well and bring everyone back with the name of thomas, however in my database name can be left empty. When the user runs the report, but does not pass in a name as a parameter we must assume that they want to see all records. In this case my report won't bring back all records where the name is empty. The way I coded it is as follows:
AND NAME = NVL(:RP_NAME,NAME)
IM being probably stupid, but I can not think anyway to get my desired outcom if I simply
AND NAME =: RP_NAME
It bring me a completely blank report.
Any advice would be welcome.
Thank you.

Hello
How about you try as below?
AND NVL(NAME,'-') = NVL(:RP_NAME,NVL(NAME,'-'))
Make sure that the user will not enter name as '-' or use any other character of NVL both places.

I have created a form to fill out that is a contract, but I need a way for the person who is to fill the form to insert their logo. Is it possible for someone to insert a logo when you fill out the form to fill out? I'm looking for all the options under the button 'add a text field.
It is not possible within a text field, either. If they have Acrobat, they can use the built-in under Tools - editing content Add Image tool.
If they drive XI or higher, they can use a button form field you will need to set up for them, but the image must be in PDF format.

How default of a multiple selection for all values setting?
I have a setting that allows the user to select multiple values. I want the default to use all values (which means basically just ignore this parameter in the generated SQL code). However, I can't create named on this calculation since it accepts multiple values, and the calculation supports only the first value. Is there a way to do what I need, without selecting all the values in the list (the LOV contains hundreds and hundreds of values so it's not a viable option). I'm not very experienced with the discoverer and don't know all the tips/solutions workaround, if you are looking for expert advice.
Thank you
Hello
You must code the parameter and the condition that he accepts the word ALL.
For example, suppose you are working with ITEM_NUMBER and you have thousands of articles. You want the user to be able to one or more key or access all THE items.
You must create a Boolean condition like this:
ITEM_NUMBER IN: ITEM_PARAMETER
OR
UPPER(:ITEM_PARAMETER) = "ALL".
So if the user key word ALL all all or or any variation of the word to be determined as true by the condition and all items will be selected. If the user does no key ALL, and then the other half of the condition will be applied and the element must be a valid element as contained in the list of all the elements. You can even create your parameter with a default value of all THE

I'm under the latest version of Firefox (40.0.3) with adblocker more like my single addon. However whenever I try to open a new tab it take ages to open because Firefox is constantly looking for an update. It takes 2-3 minutes each time. Did you try refreshing Firefox, uninstall and reinstall without success. My system is 8.1 Win on a Lenovo PC i7. Everything worked well until the last FF update. I have no problem with the same version installed on my laptop.
Any help/suggestions would be apprciated. Thank you.As long as it works. Play well.

Colors and photo look terrible quality when set as wallpaper and after emailing, help?
Hello world!
so I recently had a problem, I think that it is possible to do with the way my pictures are saved.
I recently had to wipe my computer and support everything on a hard drive, so I had to re install photoshop. Since the wipe I had some problems with the way my photos look when I have them set as bottom of screen or when I send an email the colors in the pictures appear very dirty and washed out and the quality seems worse as well but who could appear just like that because the photo is already so horrible. When I discovered photos in my photo gallery in my documents they look very well,they look good in photoshop and they appear normally when I transfer them to Web sites, the problem only seems to occur when I email them and when I set them as the background.
Here is an example of one of my photos, the background image is the good image of high quality with the colours displayed correctly. Above is what happens to the image when I put it as my background or when I send by e-mail. This would be a matter of CMYK? I thought that I double checked and all my settings were correct, but at this point I'm pretty frustrated
Does anyone have an idea what is happening here?Thank you!
Hi emmav,
It seems to be a problem due to the change of color space.
It seems that Photoshop working on ProPhoto RGB, and after saving the image, the color space is defined as sRGB.
Suggest you follow these steps in Photoshop.
1. open the image in Photoshop
2. go in the Edit > convert to profile > change the Destination space to sRGB > click OK
3. save the image and try to download on mail, or set as background.
Kind regards

My sound levels barely increased at all when setting in the timeline panel
Hello.
I'm new to Premiere Pro (of the CPF).
When I case to increase noise levels using the yellow that handles live on the actual audio track in the timeline, they increase only by a very small amount when you drag 'up '. If I slide down, I can reduce them to zero (-60 dB), but I can't increase them significantly greater than 12.
I have other titles who desperately need to be stronger. I tried increasing using 'Amplify' hearing, but disrupts the audio to make it sound sounds garbled and 'underwater '.
I hope there is a fix for this.
Thank you.

Try:
Right click on the audio clip in the timeline panel and increase the Gain.
This will increase the range available with the 'elastic '.
