What is ‘Where 1=1, 1=2’ in Oracle SQL?

By TechOneStop

Question (Posted by Michael using Contact Form under ‘Contact US’ page):
What is the purpose of using where 1=1 and 1=2 in Oracle SQL?

Answer by TechOneStop:
Hi Michael, thank you for posting your question on our discussion forum.
In Oracle database, where 1=1 means true and 1=2 means false because 1 is never equal to 2 🙂
You could use any number like 2=3 or 3=3, only thing that matters here is both numbers are same or not.
Let us give you an example. Suppose we have to create a table (table_b) same as another table (table_a) but do not want to copy any record from table_a, only table structure will be same for both tables. Here we can write query like below:
CREATE TABLE TABLE_B AS SELECT * FROM TABLE_A WHERE 1=2;
– This will create table_b same as table_a without copying records from table_a, only table description will be copied to table_b.

Now if we want everything from table_a will be copied to table_b, write query like below
CREATE TABLE TABLE_B AS SELECT * FROM TABLE_A WHERE 1=1;
– This will copy table structure, all records from table_a to table_b.

Even you could use string also like ‘tech’ = ‘techonestop’ or ‘tech’=’tech’. You could use ‘where 1=1’ or ‘1=2’ in any query like SELECT COUNT(*) FROM TABLE_A WHERE 1=2;

What is Caret Browsing ( or Caret Navigation) ?

By TechOneStop

Have you heard about Caret Browsing? This is quite old technical term but if you are not keyboard savvy person, you would not be familiar with caret browsing or caret navigation.
Like most of the people, you probably use mouse to select text on a webpage during internet browsing and just for typing purpose, you use keyboard. But what would you call it, if you can select text on a webpage by using keyboard only? This is what we call as called Caret Browsing or Caret Navigation where a caret (also known as ‘text cursor’ or ‘text insertion cursor’ or ‘text selection cursor) is used to navigate within webpage, same as Microsoft Word. But this feature is not supported by all browsers, Internet Explorer and Mozilla Firefox support Caret Browsing.
To enable or disable Caret Browsing on a webpage, just press ‘F7’ function key. It will prompt you to turn Caret Browsing on, press ‘Yes’ and Caret Browsing will be enabled. Now you can use various navigation keys on your keyboard including ‘Home’, ‘End’, ‘Page Up’, ‘Page Down’, 4 arrow keys to select text, hold ‘Shift’ key and move the caret to select multiple lines. Almost it looks like a cellphone browser, quite useful when you are using laptop touchpad rather than a mouse.

To enable caret browsing in Internet Explorer and Mozilla Firefox:
– Press F7 function key and then click ‘Yes’ on the popup window

– To enable Caret Browsing for new window and tabs (only for Internet Explorer), click on ‘Tools’ (‘Gear’ icon on top right hand corner), go to Internet Options > Advanced and mark the check box ‘Enable Caret Browsing for new windows and tabs‘ true.

To disable Caret Browsing, press F7 again. If the checkbox ‘Enable Caret Browsing for new windows and tabs‘ is marked, uncheck it.

Use of Keyboard Function keys (F1 – F12)

By TechOneStop

Every keyboard comes with a set of function keys (F1 through F12) but do you know functionalities of those function keys (or fn keys)? Sometimes in multimedia keyboard or compact keyboard, these function keys come as secondary functions on other keys like brightness, sleep, play media, player, mute. In such keyboard, to use function keys, you may need to press another special key ‘fn’ (beside Windows key) and then any function key. These function keys can be used with combination of other keys like ctrl or alt or shift.
Each function key is built to perform specific task but it may vary based upon operating system and the kind of program you are using right now. Let’s see few common functionalities that can be performed using these function keys. Few of such functionalities you may have used, few not.

F10:

– In many programs, Shift + F10 opens up the menu window, equivalent to right-click

Conclusion:

We have tried our best to give you functionalities of all Function keys or fn keys (F1 – F12). But we may have missed out some important uses of these function keys and that’s what we have readers like you. Please let us know if you have come across any other functionalities of these function keys. We will publish it with your name.

Configuring Siebel Open UI – Change application loading image

By TechOneStop

Configure Siebel Open UI - Change application loading image

‘Configuring Siebel Open UI‘ is our next series where we will discuss how to customize application as per business requirements.

Well,

Have gone through all Siebel Open UI training articles?

If not, we would suggest you to read Open UI tutorials first and then start configuration.

Now its time to customize Siebel Open UI application.

We will start with few easy and interesting configuration requirements. Later we will discuss actual business scenarios.

Remember,

You must follow best practices as much as possible during Siebel Open UI configuration.

So,

Lets start with a simple requirement – change the application default loading image.

Though it does not have much business impact but we have seen many customers to change default loading images.

By default Siebel Open UI loading image looks like this – (spinning wheel).

We will change it to this – (running man).

Though our custom image looks like static image but actually it is an animated image 🙂

Configuring Siebel Open UI -Change application default loading image

Sounds interesting?

Lets look configuration steps.

Steps for configuring Siebel Open UI loading image:

1. Verify custom image size

2. Rename out of box loading image (loadingAjax.gif)

3. Copy custom image

4. Verify Siebel Open UI application

Step 1: Verify custom image size

Very first step is to check custom image size. Image size must be less than or equal to 32 X 32 pixels. Otherwise Siebel will display only part of the image during application load.

To resize custom image, you can use any third party tool like Microsoft Office picture Manager, Picresize .

If you are using animated image, then don’t forget to save it with .gif format.

Step 2: Rename out of box loading image (loadingAjax.gif)

Do you know that loadingAjax.gif is responsible to display spinning wheel during application load?

So, before copying the custom image, rename ‘loadingAjax.gif’ file to keep the out of box image.

To rename the file, go to IMAGES folder under ..Client\PUBLIC\enu\IMAGES (for dedicated) or ..webserver\PUBLIC\enu\images (for web client), search for the file ‘loadingAjax.gif’ and rename it.

Step 3: Copy custom image

Now copy-paste your custom image file under IMAGES folder and rename it as loadingAjax.gif.

Step 4: Verify Siebel Open UI application

Delete browser’s cookies / history and launch the application. You should see your custom loading image instead of default image.

Simple and easy, isn’t it!!

If you have changed the default loading image in Siebel HI, then you are already familiar with these steps.

We have followed almost similar approach for Open UI also.
