Can we careate relationship from this chk out

can we create relationship between two table without assigning any primary key or any constraint for example there is 2 table whithout any constraint...
1 emp
emp_name varchar2(20)
dept_id number
2dept
dept_id number
dept_name varchar2(2)
now can i make any relation ship between emp and dept tables..

Hi,
Sorry, I'm not sure what you're asking.
Joins and other SQL operations involving those tables will work whether or not they have primary key or other constraints. In that sense, you can have a relationship without constraints.
Guido is right: Oracle has provided some useful tools. You've already paid for them. Why not use them?
If you need to do something that Oracle is (apparently) not providing, describe what that is.

What is the "Other" category under storage and how can i delete items from this?

My disc is almost full. "About this Mac" says that I have 47 GB of "Other." What is this Other and how can I delete items from this?

For information about the Other category in the Storage display, see this support article.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown asBackups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install ODS in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size with the largest at the top. It may take a few minutes for ODS to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal.

When I was talking on phone, suddenly the phone was switched off. i tried to switch it on but it gave the message....connect to itunes for set up. when I connected it to itunes...it gave the message, itunes can not read data from this iphone, restore it

when I was talking on phone, suddenly the phone was switched off.
i tried to switch it on but it gave the message....connect to itunes for set up.
when I connected it to itunes...it gave the message, itunes can not read data from this iphone, restore it to factory settings. It also said while restoring ypu will lose all media data but you can restore the contacts.
I restored the factory settings....the phone was on recovery mode...it was verified by itunes and all that..but in the end it again said that iphone has some problem and can not function right now.
after that when ever i connect it with itunes, it gives the message, it can not activate the iphone further, try again later or contact customer service.
What to do now?????? Customer service people say..it is hardware problem

If it's a hardware problem, then the phone will need to be replaced.
There is no magic that can fix a hardware problem.

I am new with iMac and I am trying to copy some file from my external HDD that a used with my PC but it does not let me also I can't delete anything from this HDD using the finder. Can somebody help me , please?

No, unfortunately, when you format a drive, it will erase all the contents. So you will need to find a temporary "storage" place to put the stuff using a PC so you have access to it. Then reformat using Disk Utility (Applications > Utilities). If only using with mac, format Mac OS Extended (Journaled) and use GUID Partition scheme under Partitions/Options. After formatting, you can drag the files back.

Can not send email from this house

I cannot send an email from any computer, laptop or phone (connected via wifi) from this house. However, if I take the laptop or phone to another place I can send with no problem. Oh, I can receive just fine.
Here's the problem. I am not using Verizon's provided email. I am using one of my own, i.e. [email protected]
Any email address (59 different accounts) that is on my server will not send from here. Now, no other Verizon user has this problem. Example: My parents have an email address from my server and it works. So does my son, as well as my brother and a few clients. None of them have a problem sending an email, and they are all Verizon customers. Yet, come to my house, use my internet and you can't send.
I am using MS Exchange 2003 and I have been an Admin for 10 years and I know what I am doing. Before anyone asks, I set my exchange to listen for port 587 as well.
I have called Verizon on numerous of occasions with no help. I called many IT friends and they keep saying it's Verizon. I called the Techs where my server resides and 7 of them attempted to figure this out and they too say it's Verizon. The only way I can send an email from my house is log onto my server remotely and send it from there, or use my phone's internet and send from there.
Now, I can understand if I had a problem with every Verizon account out there, meaning if no one else using the email from my server couldn't send, but when it only happens here at my house it makes no sense.
I have tried everything. I only had my laptop plugged directly into the modem (bypass the router) nothing. Got a new modem - same thing, still can't send.
Oh, I can send emails with the Verizon email provided though. Just not mine own.
Oh, I do have my own webmail setup on my server. I can log on to it via my browser and send from there just not from Outlooks, Thunderbird or any other 3rd party email.
Any ideas or help it greatly appreciated. I've gone through this for over a month and it's driving me crazy!

For the sake of example, we are going to pretend that we are setting up your fictional account. Using "[email protected]" as the 3rd party address and "[email protected]" and the password for logging into that account in webmail is "fakepassword" - Again, this is a fictitious account for the sake of an example.
The settings for using Verizon's servers would be:
Incoming Server: incoming.mydomain.com (or whatever your 3rd party server is) - For this server you set up everything according to your domain's settings.
Reply Address: [email protected]
Outgoing Server: outgoing.verizon.net
Server Requires Authentication: Yes
Username: fakeacct
Password: fakepassword
Requires a Secure Connection (SSL): No
Port: 25 (although 587 also works.)
These settings should work unless you have a Verizon/Yahoo account, in which case the outgoing server name is: outgoing.yahoo.verizon.net
Hope this makes a little more sense.

Can USB extension cable from nano burn out tower's USB port?

I recently plugged my 1GB nano into my Mac flatscreen's USB port and got a message that this port was too slow. I used it anyway but it did take a looong time to charge the nano. Normally I use the two ports in the screen to park a couple of dongles and since that port is slow for iPod purposes , I decided to buy an unpowered USB hub, 1 to 4 variety to run from the tower.
My G4 is in a closet with a not-so-accessible port on the back so I have a 6 foot extender cable coming from the tower which connects to the hub and from there I plug in my camera and keyboard - but so far not the nano. The guy at the store where I got the hub told me that an iPod nano recieving power from this settup might burn out the USB port in the back of my G4. So I haven't tested that! Anyone know if this is true or if it's just uniformed blather from a drugstore computer sales tech?

The "too slow" message you received has nothing to do with how long it takes to charge the Nano, it is telling you it will take longer to sync the Nano. If the port on the screen charged your Nano it didn't take any longer than any other port will.
A USB extension cable will not burn out the USB port on your computer.

I can't reject call from this number : 00 000000000

Hi,
Can someone help me with this ?
I've got an iPhone 4S with a french mobile phone operator.
Twice a day, I receive a call from this number : 00 000000000 (only zeros).
I can't reject the call, and there is never a message left on my voicemail.
My phone operator told me not to answer those calls, as they might be a fraud attempt.
They also told me it is impossible for them to block incoming calls on iPhones.
Can someone help me with this, even give me only information ?
Thanks.

How i can i prevent Apps from being dragged out from dock?

Before Mavericks i once applied some switch via command line that prevented removing Applications via dragging out.
But this way it still allowed changing the order or still allowed remvoing via right-click menu.
Sadly i cannot find the command anymore and all solutions i found after googling use the immutable boolean which results in a completely statically locked Dock. But this is not what i'm looking for.
How can i specifically disable the drag-out removal of Apps from the Dock?
Thanks!

You can't. You can only "hide" them.

I have all my old photos from my PC on a Maxtor external hard drive. How can I transfer them from this to my Macbook Air?

I'd like to transfer my old photos from my PC which are stored on a Maxtor external hard drive to my Macbook Air. Is there an easy way of doing this? I don't know if the Maxtor hard drive is Windows specific or if it's compatible with Mac. Anyone know?

It should be fairly simple. The Maxtor should be recognized as "read only" since it's formatted for windows. Connect it and in iPhoto select, iPhoto > File > Import to Library.. > Point to your external hd.
