How to deal with Menu select when there are NULL or a value with SQL
I have a Menu(:P_55X) SELECT with:
"NULL VALUE DISPLAY" = NULL
'NULL RETURN VALUE' = NULL
The graphical query is as follows.
SELECT NULL LINK,
START_DATE "FOR_MONTH",
ROUND(AVG("SLA"),3) "SLA_UPTIME"
from SLA_TIMES_ZABBIX
LEFT JOIN (SELECT DISTINCT NODE_NAME,OS_TYPE from CMS.CMS_NODE_OS where remove_dt is NULL) OSNODE on LOWER(SLA_TIMES_ZABBIX.NODE_NAME)=LOWER(OSNODE.NODE_NAME)
where OS_TYPE=:P55_X group by START_DATE order by START_DATE ASC;
How can I accout for the (: P55_X) variable is sometimes NULL and not null sometimes. which means I can't use the '=' when values is null because I need an IS NULL it.
The column in the database has a value or is set to NULL.
Thank you
Robert
where (OS_TYPE = :P55_X OR (:P55_X IS NULL and OS_TYPE IS NULL))

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.

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.

The installer: We have multiple vCenters each with their own SSO. We must build a minimum install vRA lab 6.1 and used the SSO to the vCenter which is the endpoint lab (and ended up having problems when this vCenter SSO had to be rebuilt and in turn liquid reconstruction vRA). Building on a vRA 6.2 Distributed Lab (based on deployment in the 6.1 reference architecture) to validate our production plan and decided to use the identity.
Question: For a production buildout there is no reason not to use the device of the identity (scalability, performance, lack of HA)? If you are using vSphere SSO, when there are multiple vCenters one that should be used for SSO of vRA? If that vSphere SSO is never removed (say on the whole things are replaced by a central SSO for all vCenters rather than each on their own, or some issue needs to be rebuilt) is there a clean way to repoint SSO vRA without a reconstruction?
Post edited by: RebeccaW (removed unrelated to Postgres question)
What I did in this case is to build a fresh cluster SSO using vCenter SSO and pointing vCAC on this one. It becomes my main source of SSO and I slowly vCenters point and other components to it overtime. You usually put vCAC SSO signed certificates and generally I find people vCenter SSO deployment in this way. To remedy this trying to modify an existing SSO vCenters and risk having to reinstall your VC because you missed the CERT, simply create a new. This also alleviates a changing overtime vCenter and spoil the vCAC SSO. The unit of identity cannot be clustered or joining existing areas of SSO. So if you are looking for HA and scale which probably does not cut it.

Yes, you can do it using a script. This code should do the trick:

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

How to hide a column in the report when there are only zeros.
Hi Experts.,.
Is it possible to hide a column in the report when there are only zeros.
Thanks in advance
VincentVincent Krishna wrote:

VincentNo out-of-the-box, but there are several workaround solutions if you want to continue an any of them:
(1) use a view selector. A single report will be a pivot table with the column, the other will have the same report less column. Users can switch reports.
(2) use a column selector. The two choices would be this column or an empty space. If white is chosen (because the user has no values), the column "will disappear" according to the report.
(3) guided use NAV. This method involves the intervention of the user. Build a small report using the single column and put a filter "is not equal to" 0. Because there is only a single column, so all lines are 0, the report returns no rows.
Use this report in the properties of guided navigation from one section of the dashboard. Assign to this "If the report returns lines" and put the report that contains the column in this section. Now add another article on your table edge and in the properties of guided navigation of this section, set on "If the report will return no rows" and it points to the small report as well. In this section, put a second version of your report without the column in it.
When the column contains all zeros, the second section with column will not display in it; the first section is not displayed. When at least a line contains a value not zero, the first section is displayed with the column, and the second part will not be.

Hello
Thanks for posting the sample data.
It is unclear what dates you want to include in the output. The following query shows how you can generate every Monday in a given range. If you only want to include the dates that are actually present in tabl1 and/or tab4, you can simplify this a bit.

, 'IW '.
) AS first_monday
