search listings: varchar2 compared to the number
I'm just getting started with Oracle and noticed the fields numbers, even number (1) or number (2), require a LOT of memory (22 bytes, this is what always comes to me in 10g XE). VARCHAR2 fields, however, seem to require bytes as well as the length of the field (5 bytes for varchar2 (5), etc.).So, I guess this is advantageous in Oracle use varchar2 fields rather than numbers in the search field when you have relatively low search lists.
Hello
Numbers in Oracle are not such as integer or long in a programming language, but they certainly do not always take 22 bytes.
You can read how the numbers are stored in metalink Note 1007641.6. In general, Oracle uses a byte for exhibitor, the rest are in base 100.
You can also check the actual size and data using the functions vsize and dump (but first read the note):
SQL> select vsize(1) from dual;
VSIZE(1)
----------
2
SQL> select dump(1) from dual;
DUMP(1)
------------------
Typ=2 Len=2: 193,2
SQL> select vsize(121) from dual;
VSIZE(121)
----------
3
SQL> select dump(121) from dual;
DUMP(121)
---------------------
Typ=2 Len=3: 194,2,22

Search can't compare with the number to decimal
Hi all
you have a problem with 'Find '.
I want to create an application that works average as mobile.
So I take the Arith. Average of 30 blocks
zaeler1 = zaeler1 + 1
zaeler2 = zaeler2 + 1
statsel (6) = 'Yes '.
Call StatBlockCalc ("Block", zaeler1 & "-" & zaeler2, "[" & ChannelNr & "] / I_ '& pruefling & '\15'")
arithmean = StatArithMeanthen I add an offset as the limit (upper limit here)
sum = ioben + arithmean
so, I want to find the measure that does not fit.
intmyresult = find ("Ch (" "[" & ChannelNr & "" "] / I_" example & "\15" "" ") ' >" & (arithmean) & "", morefail ")
but the line with fin produce an error. :
"
Find ("ch("[1]/I_4812\15") > 1,415"", 2) down rights Klammer").
"
I use Diadem 14.0
Someone at - it an idea?
Thank you
Michael
Hi Michael,
Brad is right that it is difficult to debug the convoluted formulas, but I would give it a try
intmyresult = find ("Ch (" "[" & ChannelNr & "" "] / I_" example & "\15" "" ") ' >" & (arithmean) & "", morefail ")
I guess you're in DIAdem SCRIPT and not in the calculator? If so, I think that your conversion of 'arithmean' is incorrect (in case you have a German localization of Windows):
What happens if you write? :
Call Msgbox (arithmean)
For me, the result is:
1 415' comma!
Is it the same for you too?
If so, your channel has an extra comma and is misinterpreted by FIND.
Please try to write:
Str (arithmean)
Instead of
(arithmean)
I hope that helps you along!
Best regards

Loop. uint compared to the number
Hi, I'm faced with a problem that is driving me crazy .
If uint accepts 0a min_value then why make a mistake internally with example number 1 and not 2 example? See code:
var array:Array = new Array (new Object(), new Object(), new Object(), new Object(), new Object(), new Object());
var length:uint = array.length-1;
var item:Object;
// EXAMPLE 1
for (var i:uint=length; i>=0; i--)
{
item = array[i];
trace (item, i); // null 4294929558...error
}
// EXAMPLE 2
for (var i:Number=length; i>=0; i--)
{
item = array[i];
trace (item, i); // [object Object], 0...
}Remember that you can only test a loop both reason I conflict var
dmennenoh is right, the expression "uint > = 0 ' always returns true, because of the significance of uint himself. If you want to use this kind of comparison, better using int or number.
In addition, since the calculation on uint number take much much longer that int and number, I always try to avoid uint as soon as I can.

How can I find the number of entries on a Web site when you use 'find '?
I press Ctrl + F, the "Find" option appears. I type in a text, the 'Search' tab does not show the number of entries. For Firefox 25.0.1, is it possible to find the number of entries using 'find '? This is really essential.
Thanks for your help!
Can I afford too, for future versions of FF, the number of entries found in a web page by using the Find must be indicated.
I'm sure that you need an add-on for that. Maybe:

I have already download Lightroom CC compared to the creative clouds of Adobe, and I also paid my creadit card money. But I do not have any email on my serial number
Creative cloud do not need a serial number. It will use your Adobe ID on which you bought the creative cloud composition.
If you need to sign in with your Adobe ID and password to activate the composition of the cloud.
Disconnect & reconnect the CC desktop application.
In case it is not signing in successfully, please try the following:
I do not know what operating system, you work on so I give you a few steps windows and MAC:
Windows:
In windows 7 go to the following location:
/ Windows/system32/drivers/etc
1. find the file "hosts".
2. open it with Notepad
3. check if you have any input for Adobe
4 remove the entries and try again to launch any product of CC
On Windows XP, go to the following location:
\Windows\system32\drivers\etc
1. find the file "hosts".
2. open it with Notepad
3. check if you have any input for Adobe
4 remove the entries and try again to launch any product of CC
Mac:
1. click on 'Go' and navigate to/private/etc
2. open the 'hosts' file and departure for all entries for Adobe.com
3 remove the entries and save the file
4. try to launch again any product of CC

Examle: I looking for a piece attached to a particular sender - in 3 seconds I with the thunderbird electronic-mail-search a list with all the messages from the special sender, but I do not see what emails contain attachments. If I could choose the column 'number of attachments' it would be useful: 0 = there is no attachment, it is foolish to click and open it: 1) I have to close this bad-opend-window and 2.) I return to the search results window because now I'm in the thunderbird main display. Some companies still send their logo like attachment = no problem: once I opened an e-mail-results of research I can see: oh, they always send a logo, so I have to search for emails with attachments 2 and so on. (Please excuse the word "sick" in my question: I'm not very good in English, the line was so short, and I did not know that I can write the details too.)

BY SPECIFYING THE NUMBER OF IDENTICAL CHARACTERS WHEN SEARCHING FOR A STRING
Hey everybody,
built-in indexOf() finds a character "." in the string "1.2.3." If value == 1.
It looks nothing if the value == 0 or 2 or a number greater than 2.
var txt:String = '1.2.3.';
var: output string = String (this);
If (txt.indexOf(".") == 1)
{
trace (output); [object MainTimeline]
}
The must be a simple method to specify the number of characters "." When you search for the string "1.2.3.".
For example, if there are 2 characters "." in the string "1.2.", then run it through a statement but if contains no 2 characters "." then do nothing.
There is a built-in function called contains , but it is mainly used in XML.
indexOf() resembles codes javascript unstable, one of these framework which unixers hatred.
You don't have to use regular expressions to determine how many points is in the string. Use of split and read the length:
var txt:String = '1.2.3.';
trace (txt. Split("."). (length);

Increase the number of items in a single page in the search
Hi all
When I do a Standard search it show 337 items found and he is 20 per page, I have a list of 10 Pages that makes 200 items, but the rest Articles 137 after 200 I'm not able to view even if I increase the number items in a 100 page I show 2 Pages with 100 items in a page that is 200 items
So, how can I see all the items, how can see all items and do not restrict the content server to display only the first 200 items
Thank you
REDAIn your config.cfg file adding something like this setting: MaxResults = 500
Save and restart your content server.By default, you are limited to the first 200 results. It is a performance practice, but if you need more you can use the MaxResults parameter.
