Hello everyone,

I have a requirement as below :

 If p=s and q=t and r=u then display a value.

I want an equivalent query in Oracle for this.

Thanks in advance.

Hi,

I have been working on Oracle for quite sometime now. I have always used the DECODE function that represents IF-THEN-ELSE clause. I read somewhere that from Oracle 8i onwards CASE statement has been introduced to get the same result. But which one out of the two is better considering both are used to do the same task?

Hello everyone,

I have a table student where other that the student name, student id, subjects, marks details, I also store whether the student has some salary or not. This last field stores the salary amount if its valid in a particular student's case or it is NULL. Any pointers on this will be highly appreciated.

Hi, I have understood all of the explanation. However, I have one question that is How can open BIOS Setup Option?

Hi there! I hope someone answers my query and helps me with it.

I have just setup my wireless network. I know my network's wireless settings (SSID, Channel, Wireless key...etc.). The problem is, I don't know how to connect my new Windows 7 computer to my wireless network.

The computer is using a built-in wireless card. If the computer is plugged directly to the router, it can go online, if I unplug it, it cannot go online.

I have a DSLR camera that uses an SD card to save my pictures into.So, I went to take pictures. I took alot of them pictures and of course I got good results, though I have to say that I am still a newbie.

Yesterday, I have to take the SD card out of my camera to do my routine maintenance checks. Everything went fine. I reinserted the card to the camera only to find out that the CARD is LOCKED!  Suddenly I cannot take any pictures anymore. It is always saying that the card is LOCKED!Please help me unlock...

Please let me know how to  resolve password issues in Windows 7?

Hi,

In my office we are in a private wireless network, where we have 30 laptop PCs.  Now my boss wants to keep an eye on our office environment, using camera from abroad or anywhere else outside of our office.

Is it possible? As I am in a private network, how can anyone access that camera from outside of my network?

My wireless router's power light keeps on blinking. It is doing that after every 30 seconds. The power light used to be steady and green before this happened. I don't know what to do.

I called support for the router but they declined to help me saying, I need to pay. My router is quite old. I don't want to invest on it anymore, since buying a new router is much more sensible.

What I would like is a simple work around that might help fix it.

I am using windows XP and recently it is taking a long time to load the windows.

Whenever I start my computer I face this problem.

It takes about 2 minutes to start.

I did not install any new hardware or software recently.

Can anyone help?
