Decode the help function
HelloI'm new to the development of Oracle.
MY requirement:
I need to fill a column "ISMSG" by YES / NO based on the following condition
When the code = the of ' or 'O'... the 'ISMSG' column should display any other YES no.
That is, output should be like
CODE ISMSG
A NO
S YES
S YES
O YES
My code for the Decode function:
CASE
WHEN s = c.code ' THEN decode (c.code, the of ',' YES, 'NO')
WHEN c.code = 'o' THEN decode (c.code, 'O', 'YES', 'NO')
END ISMSG
My code is correct? If Yes is the best way to do it?
If this is not the case, correct the code.
Is there an effective way to do it?
Thanks in advance.
Hello
You can use CASES or DECODE for this; There is no need to use both.
With the help of CASE:
SELECT c.code
, CASE
WHEN c.code IN ('S', '0') THEN 'YES'
ELSE 'NO'
END AS ismsg
FROM table_x c;
Using DECODE:
SELECT c.code
, DECODE ( c.code
, 'S' , 'YES'
, '0' , 'YES'
'NO'
) AS ismsg
FROM table_x c;
I suggest that you forget to DECODE and use always the CASE, at least while you are beginner.
CASE may do everything they can to DECODE. There is a little bit simple, situations where DECODE is a little shorter than the CASE and therefore a bit clearer, but only a little and, as I said, these are just simple situations, and CASE is clear enough in them.
DECODE is never much shorter or clearer than the CASE. The reverse is not true: there are many situations where the CASE is much, much shorter and lighter than DECODE.

Hello
When I tried to use the help function Adobe Prhotoshop CS5.1 a pop-up message shows errorcode (7) advise to reinstall the product. So I did, but it did not work. What can I do more? Mind you, the help in bridge function works as it should and the two products are installed at the same time.
Kind regards

Thanks, I found a few topics on the error. I reinstalled and now it works.

Gurus,
Please help me with a decoding function.
doknlbc can be null or different bnuinfc in some occasions.
Select dokkeyi, (doknlbc, null, 'no emp_id', bnuinfc) decoding as dok emp_id, bnu
where doknlbc = bnunamc and dokkeyi in (6545,6525);
Result
EMP_ID DOKKEYI
6545 70348
Result, I want to!
EMP_ID DOKKEYI
6545 70348
6525 no emp_id
Thanks for the help!Try this:
select dokkeyi, decode(doknlbc,null,'no emp_id',bnuinfc) as emp_id from dok, bnu where ( doknlbc = bnunamc or doknlbc is null ) and dokkeyi in (6545,6525);

How to implement a callback to the help function call library function node in LabView?
I try to call a fuction from a SDK.dll library by using the node call library feature. The SDK has been provided to
me and I don't have the source code, just the .dll and .h files.
The SdkSetPropertyEventHandler function has a function of recall as one of its parameters. How to apply the
callback using the NSI node? I'm a good programmer LabView but this is my first time using the library to call
Function node. I read all the info I can find on the web site of NOR and the discussion Forum, but can not understand
This one out. I'm using LabView 8.6.
The deacribes SDK.h function as:
Function: SdkSetPropertyEventHandler
(SdkSetPropertyEventHandler) SdkError SDKAPI
SdkCameraRef inCameraRef,
SdkPropertyEvent inEvnet,
SdkPropertyEventHandler inPropertyEventHandler,
SdkVoid * context);//
Description:
Registers a callback function to receive the status
change the notification events for the States of property on a camera.
//
Parameters:
In: inCameraRef - designate the object camera.
inEvent - designated one or all the events will be completed.
inPropertyEventHandler - designate the pointer to the callback
function to receive the camera property-related events.
inContext - designated application information must be passed
way to the callback function. All the data necessary to
your application can be passed.
Output: no
//
Returns: A sdk errors.
-----------------------------------------------------------------------------*/A separate header called SDKTypes.h file contains the following data:
typedef SdkUInt32 SdkPropertyEvent;
typedef SdkUInt32 SdkPropertyID;
typedef void SdkVoid;typedef struct __SdkObject * SdkBaseRef;
typedef SdkBaseRef SdkCameraRef;/*-----------------------------------------------------------------------------
SdkPropertyEventHandler
-----------------------------------------------------------------------------*/
typedef SdkError (SDKCALLBACK * SdkPropertyEventHandler))
SdkPropertyEvent inEvent,
SdkPropertyID inPropertyID,
SdkUInt32 inParam,
SdkVoid * context);Thanks for your help.

Hi Rolfk,
You are absolutely right. This article describes what you were talking about? I'm just trying to get as much information as possible on this thread if the solution is easier to find for the future. Thank you.
Yes, but I find the idea of using .net to call a LabVIEW VI as callback function C a bit as using a roll of Steam ironing your pants. Why do it? Well the steamroller has extra security guards that make it less likely that you'll break your pants in the process, but it's not elegant IMHO.
Write a C DLL that translates between a C callback and a user event LabVIEW using the PostLVUserEvent() of the interface of the kernel to run LabVIEW function seems so eleganter for me. Yes, it's a bit of programming in C, but good!

Decode the help of HTML special characters
Hello
I use a BrowserField to see others come from HTML content via the server.
But the data being sent is encrypted (with special characters as "< p & gt")
So I think I must decode before moving on to the BrowserField.
Can someone offer me please how to decode?

and the APP ("SAPPI", "SAPPI", "SAPR3") and INTERVENE ('9320 ', '9332','1208 ')

the result of this query:

SAPPI 600

And I want to have something like output

IE.the APPP and STEP combinations. Must return the specified values
SAPPI & 9320-> LOC (here SAPPI IE APP is the same for both... but it's a coincidence IE APP can be sliced also)
SAPPI & 9332-> tsw

Options, I tried:

A full table scan might be the fastest way to get results. Do you have any reason to think that it would be faster to go through the index? How selective are the clues? In other words, what is the percentage of rows in the table correspond to each of the values in the WHERE clause?
2. is the right to approach?
It depends on what you're trying to do, which is not at all clear to me.
Would the use of the concat operator in the function decode work better for my needs?
Something likeSelect decode (APP |) STEP, 'SAPP9332', 'X') of TRANSACTION_HISTORY where
If you use this approach, look out for the problem Ab asse crevit . For example, if you have these 4 rows and 2 columns:
str1 str2 ---- ---- (NULL) FOO F OO FO O FOO (NULL)
There are 4 values of distict of str1 (counting NULL) and 4 separate values of str2, str1 but | str2 is the same for each of them. In the above example, it there is no way to know, just by looking at the concatenated string, including str1 and str2 ends begins. Maybe it's not the case for your specific data (for example, if the application is still exactly 5 characters long). otherwise, you may need to add some kind of delimiter, like this
app || '+' || step
where you know that '+' never occurs in one of these columns.
3. ANY other approach / request for my requirement.
CASES, as I mentioned in your previous message:
Decode the help function
and as you have used above.In this thread, you said "I have to use the decode function. Why? It is a competition of school Etudieeo DECODE is explicitly required? Why you don't want in the best way, what that turns out to be?
Your WHERE clause:
AND APP IN ('SAPPI', 'SAPPI', 'SAPR3') AND STEP IN ('9320', '9332', '1208')
admits 6 possible combinations of APA and step:
app step ----- ---- SAPP1 9320 SAPP1 9332 SAPP1 1208 SAPP3 9320 SAPP3 9332 SAPP3 1208
but you are looking for only 3 of these combinations in DECODE it or the expression BOX. (Have 2 copies of 'SAPP1' e list won't do any good, but it does hurt real, either.)
By the way, is "SAPPI" app with the letter 'I' at the end, or "SAPP1", with the number '1' at the end?Published by: Frank Kulash, March 24, 2011 19:44

need help to get the value using the REGEXP_REPLACE function.
I am trying to extract the value placed between "< listitems >... < / listitems >" but I am unable to get these value using the REGEXP_REPLACE function.
select REGEXP_REPLACE('<InputParameters></ParamSet><listitems>14545454</listitems></ParamSet></InputParameters>' ,'(<InputParameters>.*<listitems>)(.*)(</listitems>.*<InputParameters>)' ,'\2') from dual;
Can someone please help me achieve this goal.required output: 1454554
Hello
You forgot the / before the last InputParameters. If fix you that, your code will work.
Here is a slightly different way:
SELECT REGEXP_REPLACE ( '
' , '^.*?14545454 (.*?) .*$' , '\1' ) AS listitems FROM dual ;Least to type, the less likely you will have to make typos.
If there are 2 (or more) elements of listitmes, 1 will be returned.From Oracle 11.1, you can also use REGEXP_SUBSTR. I have Oracle 10.2 avaialable now, so I can test the following, but I think you'd say:
SELECT REGEXP_SUBSTR ( '
' , '14545454 (.*?) ' , 1 , 1 , NULL , 1 ) AS listitems FROM dual;When it comes with the text that is or looks to, XML, consider using XML functions.

Help please, LCC does offer the same functionality as Adobe Stratus? How?
I found in the FAQ:
LCCS provides the same functionality as Adobe Stratus?
Yes. LCCS offers the same technology as Stratus today for P2P audio and video streaming. LCCS also offers a developer, framework and hosted service designed for real-time collaboration as well as the ability and the ability to connect RTMP connections with customers RTMFP.
The question is how can connect my existing application in Stratus with you CAC?
I don't want to use LCCS framework, I won't use the RTMFP Protocol as Stratus phone sample video, but in a commercial product, it is possible to supply?So, if possible, where I point my connectUrl key and developer of stratus in a supply service?
Thank you very much.
Hey elattanzio, I went through the same thing how you feel when I first tried begin with low-COST airlines. I wanted to create a connection to peer 2 peer between two applications flash with no server involved. I also moved the example of Stratus to the LCC.
The short answer is THAT LCCS always uses rooms to connect people. You can make a direct connection in hand pair using rtmfp in your application. In this case first of all your users connect to a room on the servers of the LCC, and then they will help you coordinate the rtmfp peer connection as you used with Stratus. So you end up with all your data flowing between two clients, but both clients are connect to the room in supply. Your customers must stay connected to companies low-cost for the duration of the video call. Now if your clients cannot establish a connection to the cause of NAT, firewall or other issues they're going back to rtmp and all traffic will now forward through the servers of the CCA. You can specify that you do not want your customer to fold well.
One other important thing to understand is the pricing model. There is an associated cost just be connected to the servers of CAC. We found it to be nominal if, but just enough to discourage you to stay connected all the time. This led me to develop our own system based on jabber, precense to see who was online and to initiate calls, etc.. Secondly the cost to say the audio and video traffic is routed through servers to SUPPLY was too high for our business model so we chose to not allow fall to rtmp. I think that the cost was reasonable based on the costs of bandwidth, etc., our model just could not bear.
So here you'll it's my understanding of things that I agonized about how to get good video chat working in our application. Yes to peer is not 100% free, but the cost isn't too bad and you get the benefits of Adobe running a cluster of servers for you. So for us the value was there. Good luck with the project.

Please report to us. I don't know the exact specifications. for stills in still, the limit is 4000 pixels in the largest dimension for PrPro.
Now, I must add that in PS. resizing algorithms are better, in my opinion, than those of PrPro and again. This means that there is nothing to gain and quality of untying, important images much larger than the size of the frame of the project, i.e. of 720 x 480 for NTSC SD projects yet. The size of the image will be the limiting factor, so scratch that.
Even in projects PrPro, I resize to exactly what I need. If I will not pan on a zoomed image, I resize it to the size of the image of the project. If I move on a zoomed image, I resize just what I need.
Good luck
