Dollar sign rating
Hi members,I just came across a pack of PL/SQL using a notation that I've never seen before, nor can find in PL/SQL reference. It is the use of $ (in a conditional statement)
Here is an example:
SQL> create or replace procedure p as
begin
$if 1 = 1 $then
dbms_output.put_line ('Why can we use dollar sign?');
dbms_output.put_line ('And no END IF??');
$end
end p;
Procedure created.
SQL> show errors
No errors.
SQL> exec p
Why can we use dollar sign?
And no END IF??
PL/SQL procedure successfully completed.
SQL> show release
release 10.2.0.3.0
Just wondering what that really is, and why would anyone want to do that? -Is some old style, Pl/SQL, or?PS: The package was written in 1997
Best regards
Peter

Variable data sets - Dollar signs appearing not
I am trying to create 100 boxes which are 100px x 100px who have a stroke and amounts of $1 - $100 in them. Very simple. After I import my .csv file in Photoshop and I export all the files, the dollar signs that are in the .csv file do not appear in the exported files. The number of young people do however. Any advice on how to make the dollar is part show?
I think you should actually include the dollar rather than the formatted cells. As Norm has shown, it works.

Basic: what is the dollar sign ($) to an average of name of column?
Periodically, I see dollar signs in the column names in the Oracle tables. For example, when I create a LOB, the LOB segment often ends in a dollar sign (or two). Sometimes when a developer creates an object, I see some of the field namess have dollar signs at the end of their.
What is the dollar sign?
Which means two dollar signs?
Just curious... they seem to function as normal characters.These are normal characters. But Oracle (and other vendors) frequently use characters such as $ who normally do not use normal developers to create agreements around table names.
For example, Oracle provides a number of data dictionary tables that use x$, v$ and gv$ as prefixes. There is nothing inherently special about these prefixes. But they convey useful information for users of these systems (x$ views are undocumented, v$ views provide information about activity on the local instance, gv$ views provide information about the activity on all instances of a RAC cluster). And using these sorts of prefixes prevents confusion between the tables of the application and the Oracle tables. Many applications, for example, have a table in a SESSION. With the prefix $ V for the Oracle format V$ SESSION table makes it easy confusion to have two tables with the same named.

Dollar sign disappears when the application of models
All my models seem to do that. I have applied the model to all the support pages and the dollar signs, I have in my code disappear causing my pages stop working... so I have to manually add all the $
for example, I have this in my template
<div id="academicyear"> <form action="${changeYearURL}" name="yearSelectForm" method="post"> <strong>Academic Year:</strong> <select name="selectedYear" onchange="document.yearSelectForm.submit();"> <s:iterator value="%{years}" var="year"> <option value="<s:property value='key'/>" <s:if test="%{selectedYear == #year.key}">selected</s:if>><s:property value='value'/></option> </s:iterator> </select> </form> </div>
and when I apply the model of this line
< do action = "${changeYearURL}" name = "yearSelectForm" method = "post" >
becomes this
< do action = "{changeYearURL}" name = "yearSelectForm" method = "post" >
any ideas on why this is happening? It's not just this case, it happens often.
Oh and I use CS4, DW10

dollar sign $ transform spilled ¿point of mark?
Hello, we have a bilingual application, and everything works fine with the selected English language.
But when a user changes the language to Spanish, the dollar sign ($) converts a query to funny research (-)
What would be the cause of this problem, and how can it be resolved?
Thank you.While you are looking for the source of the problem, you can use an effective solution in the meantime:
In the definition of your Page, in the regions, interactive report, click the icon to change the element you want to change, find the Format mask and select Format the first mask in the list ($ 5 234,10)
This field displays the Format mask FML999G999G999G999G990D00
Change the letter 'L' for a sign $, like this:
FM $999G999G999G999G990D00
Apply the changes -
Ignore the dollar sign and comma
Can someone help me please. I have two fields that perform calculations based on what a user entered for a value of homes. Basically I want to ignore the dollar signs and commas if they put in the value of the homes. So if the user enters $120,000.00 I still want the value to be calculated even if he has the dollar sign and the decimal point in it... Any ideas?

Using the Dollar sign ($) in an implementation of the user-defined function
Hi all
Just a quick question: how would you use a dollar sign ($) in the (Oracle) implementation of a user function? I ask because the table name that I use in the application happens to contain a dollar sign (I$ _FACT_SALES) and post the results I get now, ODI bed the $ as a reference to a variable, the sign $ so my name removed from the table during execution (I_FACT_SALES). Is there something like a backslash or some other character that could be inserted before the $ for him be part of the name of the table?
Any response would be greatly appreciated.
Thank you very much
MarcoYou have 3 options:
1.) try using the tablename parameter in the following quotations: ' MY$ TABLE "or maybe MY$ $TABLE using double symbol $
or
2) 2) I found this snippet: odiRef.getInfo (\\u0022DEST_WORK_SCHEMA\\u0022) + \\u0022.\\u0022,\\u0022\\u0022)?. "So on these lines, so that you can use \\u0022 as a symbol.

change the dollar sign to pound sign on button 4
Remember - this is a public forum so never post private information such as numbers of mail or telephone!
Ideas:
- You have problems with programs
- Error messages
- Recent changes to your computer
- What you have already tried to solve the problem
Hello
If you use the UK keyboard, press SHIFT + 3.
If you use the keyboard, with NumLock on, hold down the ALT key and type 156 on the keyboard. When you release the ALT key, the symbol of the book is displayed.
You can also change your keyboard type in Windows 7.
I hope this helps.

How to search files of names that contain the dollar sign ($)?
I typed "$" in the search box and all the files were returned. I tried------$ and no items found.
Hello
Use the wildcards * and?
* means 'everything' or 'all '.
? means 'any character a' then? We hear every two characters and so on.
So * $*. * would find all the names of file with a $ in the name with any extension.
?$*.? XE'd find filenames with characters 1 or not before the $ and with the
extensions that contain characters 1 or not before a xe as .axe, .3xe or just in. XE.Tips for finding files

Rounding numbers to millions with the dollar sign in InDesign
I've been struggling with this problem for over a year now and I need to start asking some experts. I have several large files that have a lot of big numbers ($millions) excellent and I need to cut them to fit into smaller cells by rounding to the millionth closest in InDesign CC. So instead of $23,564,950.00 I need $23.6 Mr. the layout of the import version does not format. It is possible to wright is a script for this? I have not found a way to do this with styles.
This isn't what you asked
If millions are made optional you get 0.8 against 817 000 and 880 000 0.9:
(function(){ app.findGrepPreferences = null; app.findGrepPreferences.findWhat = '(?<=[$])(?:\\d{1,3},)?\\d{3},\\d{3}(?:\\.\\d\\d)?'; var found = app.documents[0].findGrep(); for (var i = found.length-1; i >= 0; i--) { found[i].contents = (found[i].contents.replace(/,/g,'').replace(/\.\d\d/,'')/1000000).toFixed(1)+'M'; } }());

Sign change Dollar to the symbol of the book English on Toshiba laptop
Hello.. I recently bought a laptop computer Satellite, a L655-S5156, PSK2CU-0HW01U model number.
I would like to change the dollar sign (shift + 3) for the symbol of the English book that I have been working in UK currency. Is there a way I can do it on this laptop? It was purchased in a store in the United States.
Thank you very much
' Legs...
AFAIK you cannot modify symbols, and to configure the keyboard. What you can do is to change the input language and define the English UK keyboard. When you press SHIFT + £3 symbol must be indicated.
Can you please test and let me know if it works for you too?
