Can I designate a column as an output to another column in the same point of view?
Hello!
I have a custom view which I use in the daily Business Intelligence KPI, which is something like this:
Select (select sum (col1) from table1) out1.
((select sum (col1) from table1) out2)
of the double
I need to reproduce the same columns that DBI will not refer me a column twice. It certainly is him asking to run the same query twice.
Is there a way in which out2 will 'just talking' to out1?
Thank you.
For example,.
SQL >
SQL > set autot on exp
SQL > create view v1 as
2 with col (select sum (sal) s of emp)
3 select s out1, out2 s of the neck;
Created view.
SQL > select * from v1;
OUT1 OUT2

Question: Is foreign key references to a different column in the same table
Hello
I'm not grasp this concept. Would you be able to provide the logic how and why you need to create a foreign key that references a column of the same table?
For example, referencing the schema, SupervisorNo @ here is a FOREIGN KEY to the "EmpNo" column in the same table.
EMPLOYEE (EmpNo, title, Fname, Lname, phone, Email, date of birth, sex, salary, HireDate, OutNo, SupervisorNo @)
Why would you want to do this and how can it be used? If you are filling out the data in the table, and this constraint is enabled, you will not be able to load whatever it is because the "EmpNo" column will be empty.
Any input you can provide me with this would be greatly appreciated. Thank you!
His name
Self-referential integrity constraints
Lets say that we have the table emp with emp_no and mgr_no columns.
Now all managers should also be an employee too. How can I check this when inserting data into this table? I applied auto integrity constraint. It would help me to make sure no handler (doesn't mean no mgr_no) must be registered if this Manager is not an employee of this organization. Which means, I won't be able to enter any mgr_no in the column until and unless that the same employee also is an employee (emp_no from the same table).

When starting, my windows xp hangs or crashes when you try to load 'personal settings '. I can't do something, but stop once again on commissioning, she repeats the same actions. What now? Thank you
Hello
Disconnect all external devices from the computer and try to restart the computer and check what is happening.
Step 1:
Try to boot to the desktop in safe mode and check what is happening. Only basic files and drivers needed to run Windows are started. If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic as possible cause device drivers. To start in safe mode follow the link.
http://support.Microsoft.com/kb/315222
Step 2:
If you are able to boot to the desktop in Mode safe, it means that the third-party application prevents the computer from starting in normal mode. To check you can configure the computer to clean start State and then try to boot into normal mode and check what is happening. To set up its own start-up follow the link below.
http://support.Microsoft.com/kb/310353
If the problem does not continues when the computer is in the clean start State follow the steps listed to identify which application is causing the problem.
Note: When you are finished troubleshooting, follow step 7 article to start on normal startup.
Hope this information is useful.

Another computer has the same IP address as mine, how can I change this?
Another computer has the same IP address as mine, how can I change this?
Original title: IP address
Hi John,.
Please go to the Microsoft Community Forum.
IP (Internet Protocol) address for the other two computer cannot be the same.
Internet Protocol (IP) addresses are unique numeric identifiers that are required for each device that connects to the Internet. Them are a common shared resource that must be managed carefully in order to ensure the continued growth and stability of the Internet. Most of the Internet is currently treated with IP version 4 (IPv4) addresses. IPv6 addresses are also in use, but not yet to the same extent. IPv6 is a newer protocol, offering a much larger than IPv4 address pool
However, you can try to reset TCP/IP on your computer.
Check out the link provided and check if the problem persists.
How to reset the Protocol Internet (TCP/IP)

can I add another license to the same e-mail address
Hello. I use creative cloud on a desktop and laptop. I could buy another computer. Can I add another license to the same account/email address? I don't see a way to do it. This is how I could use licenses on up to 4 devices.
Thank you
Andrew
Hello
In case you want to use on 4 machines, please purchase a subscription on a different Email address.
Adobe has moved to based on the identity of license with a technology that will not support multiple licenses and products, you can buy only one membership per Adobe ID. If you need two memberships creative cloud, you can buy each with a unique Adobe ID. You can also buy a creative cloud for membership of the teams, which allows you to buy and manage several places under an own account.
Also, you can read:-https://helpx.adobe.com/x-productkb/policy-pricing/error-maxium-acitvation-exceeded.html
I hope that answers your query!
