Hi,

I have to form a query in such a way that all the NULL values in a column are grouped together and Not NULL values are grouped separately.

In algorithm form my output should be:
Total_Count            Columnxyz
number1                    NULL
number2                    All Not NULL

Hi,

I am new to Oracle. I have a doubt regarding two basic queries I see everyday at work. Say, I have a table employee with 1000 records. When I fire:

Select count(*) from employee;

And

Select count(1) from employee;

They both give me the same result - 1000.

Is there any difference between count(*) and count(1)?

I have 3 access points, that I plan to install on my Local Area Network and I want to use them at the same time.

Is this possible?

Hello everyone. I just created my first ever website for my business and I want to ask for help regarding search engine indexing. Right now there are two major search engines dominating the market, Google and Bing (since Yahoo is now powered by Bing). My website got indexed in Google within 48 hours without even doing anything. However, when it comes to Bing Search, it seems like my website still doesn’t exist. Bing is not indexing my website on their search results page? Please advice on what to do?

Hi everyone,

I need help with my internet.  It seems to disconnect, when I leave my laptop. What I usually do is, just leave it when I am done using it.

Earlier,  whenever I come back to use it, I still had my internet working.  However now, when I come back, It is not connected and I cannot browse the net.

I'm using a wireless connection and the router my  brother is using, is just a few meters away.

Please help.
