Can i create 23 functions in one proc
Hi,
Can I create 23 functions in one proc. In that functions data is manipulating at a time 6000 to 50000 records.
Eg: 6000 time taking 2 minutes
Will get any performance issue when I manipulate 20000- 50000 records at a time.
There's no performance issue.
Pls suggest me,
-Thanks,
Well from Pl/sql perspective you can declare any number of functions within a procedure.
But Ennisb is right: you should be more cleare in what you try to achieve.
AQ is really, really fast. So if these 5000, 6000 records are enqueued on a queueu you can create a job that dequeues and processes these a message at a time until the queue is empty. This job you could schedule several times using dbms_job in parallel. Then you'll find that the processing is really fast.

Can't create a function in database
William Robertson and I have described some advices for you.
Is my English poor?
If you couldn't get theirs (mikerault, William Robertson et al.) and my advices,
You can ask that on ITPUB (this is Chinese site).
Here it is. http://www.itpub.net/
And this site is not only for Oracle.
I think they can help you in Chinese words.
PS.
I learn that
'Gongrezhan' means the center of supplying heating to building,
and this center is the characteristic systems in Beijing or more cold district.
PS.2
Your script includes simplified Chinese character-set.
Even if you were not Chinese person,
we all think you can understand Chinese words. -
Can we create a folder in one desktop without sharing that folder in other desktop in mac?
I have created a few desktop in my mac. Can i create a folder in one desktop, which does not share in other desktop?Can I have different folders in different desktop? how to do that?
No. Desktop spaces affect only applications and their windows. If an icon appears on the desktop it appears on every desktop.

Certain Numbers templets allow you to drag and drop contacts to populate cell data, how can I create that functionality in my own tables?
If you haven't come across the workarounds thread you may find helpful tips there on this and other ways to work with Numbers 3.
ronniefromcalifornia discovered how to bring contacts into Numbers 3. As described in this post:
"Open Contacts
Select all the cards you want
Copy
In Numbers, in a table, select cell A1
Paste
Boom. Works great. Even brought in the pictures. Cool."
So instead of drag and drop, just select in Contacts, copy, and paste into Numbers

How can I create a function of sound volue from time using AudioQueueBufferRef??
I have a question how can I analyze class AudioQueueBufferRef, for creating a function of sound volue from time?? Here is what I get . there is AudioQueueBufferRef fillBuf = audioQueueBuffer[fillBufferIndex]; volume height is 2000 elements from SInt16* coreAudioBuffer = (SInt16*)fillBuf->mAudioData. so function looks like H(t*i)=coreAudioBuffer[i] where t = 1/sampleRate = 1/22050 but here is a problem. my program gets sound and uses a class AudioStreamer for this. AudioStreamer has 3000 lines when I play music from Free Internet Radio - SHOUTcast Radio - Thousands of Free Online Radio Stations. internet radio - my problem is as follows either I dont know where 85 % of sound information is or I dont know how I can analyze class AudioQueueBufferRef
Here is the code where I analyze Buffer.
{@synchronized(self)
if ([self isFinishing] || stream == 0)
return;
inuse[fillBufferIndex] = true; // set in use flag
buffersUsed++;
// enqueue buffer
AudioQueueBufferRef fillBuf = audioQueueBuffer[fillBufferIndex];
fillBuf->mAudioDataByteSize = bytesFilled;
// ======>in this place I analyze Buffer
if (packetsFilled)
err = AudioQueueEnqueueBuffer(audioQueue, fillBuf, packetsFilled, packetDescs);
else
err = AudioQueueEnqueueBuffer(audioQueue, fillBuf, 0, NULL);
when bitRate = 24 buffer has the following options int size=(fillBuf->mAudioDataByteSize) == 2000 double sampleRate=asbd.mSampleRate == 22050 numberOfChannels = asbd.mChannelsPerFrame == 1 it turns out that duration of play buffer float bufferTime =(size/numberOfChannels)/sampleRate == 0.1 number of buffers per second float numBuffersInOneSeconds == 1,5 duration of play all buffers per one second numBuffersInOneSeconds * time == 0.15 so it is 15 % of all information
as a result If buffer comes at 0.0 seconds he lasts up to 0.1 seconds.farther in my function there is no volume. second buffer comes in 0.7 seconds and lasts up to 0.8 seconds. but in reality the sound doesnt breaks. Maybe I'm doing something wrong .please tell me.
just for comparison
when bitRate = 32 buffer has the following options int size=(fillBuf->mAudioDataByteSize) == 2000 double sampleRate=asbd.mSampleRate == 22050 numberOfChannels = asbd.mChannelsPerFrame == 1 it turns out that duration of play buffer float bufferTime =(size/numberOfChannels)/sampleRate == 0.1 number of buffers per second float numBuffersInOneSeconds == 2 duration of play all buffers per one second numBuffersInOneSeconds * time == 0.2 so it is 20 % of all information
when bitRate = 32 buffer has the following options int size=(fillBuf->mAudioDataByteSize) == 1660 double sampleRate=asbd.mSampleRate == 44100 numberOfChannels = asbd.mChannelsPerFrame == 2 it turns out that duration of play buffer float bufferTime =(size/numberOfChannels)/sampleRate == 0.02 number of buffers per second float numBuffersInOneSeconds == 10 duration of play all buffers per one second numBuffersInOneSeconds * time == 0.2 so it is 20 % of all informationYou cannot write custom commands for expressions.
That being said, there are a couple of options:
Create a subsequence with a single step. Use a parameter of the sequence as "function parameter".
Create a custom step type including a substep module which implements the function. Add an edit substep to enable the user of the steptype to gracefully change the parameter.
Store the variable parameter in a local/file global variable and modify the value in each step. This will, at least, keep the "function" the same for every step.

How can I create a function using TestStand variables and call it from a step's Pre-Expression?
In one sequence I have dozens of Pre-Expressions which are almost the same thing, like this...
Locals.tagID = (Parameters.singlePhaseEnabled ? "L" : "D") & Str(Locals.phase) & "006"
...and the only thing different is that three digit string at the end ("006" will vary). How can I write a function that I can call from a step's Pre-Expression so it would look something like this? ...
Locals.tagID = MyNewFunction("006")You cannot write custom commands for expressions.

Thanks for you help!I read ITPUB, and understand detailed situation a little.
The problem is not that any error occur on compiling,
but that compiling slows down with some conditional clause(*1).
It takes half a day or more(*2) to compile.
I think that must hung up.
Really? Is it really happen?
If that is true, You had better contact Oracle Support.
(*1)
The additional condition is like as follows.
and (t.MB_named_column1,t.MB_named_column2) in
(('MB_data1',0),('MB_data2',pvc2Bmid),('MB_data3',pvc2Zbmid),('MB_data4',pvc2Grzid),('MB_data5',pvc2Lfid),('MB_data6',pnumYhid))
Here, MB means MultiBytes.
(*2)
'half a day or more' is my literal translation.
It may mean only 'very long time'.

Thanks for you help!I try translating from Chinese to English words including column name and data.
But, I can't understand the Chinese word Gongrezhan, so this is Pinyin.
And, I have not analyzed your function, yet.
Because, I just now must go to Chinese conversation class.
By the way, it should be that tables and columns named by multibytes is enclosed by double quotation.
For example,
select t.更新, -> select t."更新"

like avg.I think you'll have trouble finding anything to take infinite parameters cos that would be bigger than the universe itself.

Can we create two Filters for one cube
Hi all,
I created two filters for one cube (in 11v), I assigned this filters to one user in shared services , so which filter work,
I think ,We have to assign only one filter for one user , please i need clarification....
Thanks
Edited by: user98631 on 12 mars 2010 05:13You can create many filters for one cube. I usually associate one group per filter and a user can have one or more groups assigned to them. Can't remember what happens when a user has access to conflicting filters (i.e. the order of preference). It is in the DBAG I am sure though.
