How to optimize the performance of this query SQL
Hello
I need to find the age for each day, but I need for all previous dates in a single query. So I used the following query:
Select trunc (sysdate) - level + 1 DATE
trunc (sysdate) - level + 1 - created_date AGE
elements
connect by trunc (sysdate) - level + 1 - created_date > 0
I get output (FOR the DATE and AGE) that is fine and correct:
DATE AGE
--------- ----------
6 JULY 15 22
5 JULY 15 21
4 JULY 15 20
3 JULY 15 19
2 JULY 15 18
JULY 1, 15 17
JUNE 30, 15 16
JUNE 29, 15 15
JUNE 28, 15 14
JUNE 27, 15 13
JUNE 26, 15 12
25 JUNE 15 11
24 JUNE 15 10
Now I need to calculate the average age for each day and I added the average in the following query:
Select trunc (sysdate) - level + 1 DATE .
AVG (trunc (sysdate) - level + 1 - created_date) AVERAGE_AGE
elements
connect by trunc (sysdate) - level + 1 - created_date > 0
Group of trunc (sysdate) - level + 1
This query is correct? When I add the aggregate (avg) function to this query, it takes 1 hour to retrieve the data. When I remove the average request function that gives the result in 2 seconds? What is the solution to calculate the average without affecting performance? Help, please
Maybe you are looking for something like this...

How to optimize the performance of this code?
I have two clips on a flash project. One of them is fixed and the other can be moved with the arrow keys of the keyboard. The two clips have irregular shapes, so HitTestObject and HitTestPoint does not work very well. I have a function that detects the collision of two clips using bitmap. I wanted to update the position of the Movie clip mobile so I put the function of collision detection under the ENTER_FRAME event listener code. It works fine, but when I add many fixed film clips (about 10 clips fixed in an image), the game (.swf file) becomes slower and slows down the performance of the PC. I thought that my collision detection function has a negative effect on the performance of the PC, so I used the class on this page: https://forums.adobe.com/thread/873737
but the same thing happens.You told me how to do to speed up execution of my codes?
Here's the part of my code:
stage.addEventListener (Event.ENTER_FRAME, myOnEnterFrame);
function myOnEnterFrame(event:Event):void
{
If (doThisFn) / / doThisFn is a variable to allow or prevent the kind of mobile film clip moved with arrow keys
{
If (left & &! right) {}
Player.x = speed;
Player.rotation = player.rotation - speed;
}
If (right & &! left) {}
Player.x += speed;
Player.rotation = player.rotation + speed;
}
If (up & &! down) {}
Player.y = speed;
}
If (down & &! up) {}
Player.y += speed;
}
The clips of film sets are wall1, wall2, wall3, wall4,... and so on
the following code checks to see how many walls exist on each image and pushes them in table wallAfor (var i: int = 0; i < 1000; i ++) / / you can put up to 1000 object of wall in the table wallA
{
If (this ['wall' + i]) / / if the wall object exists, push it into the table wallA
{
wallA.push (this, ['wall' + i]);
}
}
for (i = 0; i < wallA.length; i ++)
{
If ( h.hitF (player, wallA [i]) | gameOverTest) / / this code checks whether or not the player (the mobile clip) hit the walls
{
trace ("second try");
gameOver.visible = true;
doThisFn = false;
}
}
I think the following codes are easy to turn and run. I think that the performance problem is due to previous codes.
If (player.hitTestObject (door))
{
Win.Visible = true;
doThisFn = false;
}
If (key) / / if there is a key on chassis
{
If (player.hitTestObject (key))
{
Key.Visible = false;
switch (currentFrame)
{
case 4:
wallA [0] .visible = false;
.x wallA [0] = 50000;
break;
case 5:
wall14. Play();
wall8.x = 430;
break;
}
}
}
}
}
It's a simple question that doesn't usually have a simple answer.
Here is an excerpt of a book (Flash game development: in a Social, Mobile and 3D world) I wrote.
Optimization techniques
Unfortunately, I don't know any way completely satisfactory to organize this information. In what follows, I discuss memory management first with sub-themes listed in alphabetical order. Then I discuss the management of CPU/GPU with subheadings listed in alphabetical order.
This may sound logical, but at least, there are two problems with this organization.
1. I don't think it's the most useful way to organize this information.
2. memory management affects the CPU/GPU use, so that everything in the section of memory management can also be listed in the section CPU/GPU.
In any case, I'll also list information in two other ways, from the easiest to the most difficult to implement and more for much less.
Two of these later inscriptions are subjective and dependent on experience developer and capabilities, as well as environmental test and the test situation. I very much doubt there would be a consensus on the order of these lists. However, I think that they are still valid.
Easier to the more difficult to implement
1. do not use the filters.
2. always use the reverse for loops and avoid loops and avoid while loops.
3. explicitly stop timers for their loan for gc (garbage collection).
4. use the weak event listeners and remove headphones.
5. strictly type variable when possible.
6. explicitly disable interactivity mouse when interactivity smile not necessary.
7. replace dispatchEvents with callback functions whenever possible.
8 it would be gc stop sounds for the sounds and SoundChannels.
9. use the DisplayObject most basic need.
10. always use cacheAsBitmap and cacheAsBitmapMatrix with air applications (i.e., mobile).
11. reuse of objects when possible.
12 Event.ENTER_FRAME loops: use different listeners and different listener functions applied to DisplayObjects as little as possible.
13. the pool instead of creating objects and gc objects ' ing.
14. use partial blitting.
15. use step blitting.
16 use Stage3D
Biggest advantage less
- Use the blitting Stadium (if there is enough memory system).
- Use Stage3D.
- Use partial blitting.
- Use cacheAsBitmap and cacheAsBitmapMatrix with mobile devices.
- Disable explicitly interactivity mouse when interactivity smile not necessary.
- Do not use filters.
- Use the most basic necessary DisplayObject.
- Reuse objects whenever possible.
- Event.ENTER_FRAME loops: use different listeners and different listener functions applied to DisplayObjects as little as possible.
- Use reverse for loops and avoid the do loops and while loops.
- The pool instead of creating objects and gc'ing.
- Strictly, type variable when possible.
- Use weak event listeners and remove headphones.
- Replace dispatchEvents by the callback functions whenever possible.
- Explicitly stop timers on loan for the gc.
16 stop sounds for the sounds and SoundChannels be gc would be.

How to improve the performance of this loop?
Hello
I have this code below performs a loop on both issues, which compares the files in them. The performance is bad. Can someone tell me how to accomplish this task in an effective way?
Please note that both folders can be on the network and most often contains 5000 + files.
for (int i = 0; i < sourceList.length; i++) { for (int j = 0; j < targetList.length; j++) { if (sourceList.getName().equalsIgnoreCase(targetList[j].getName())) {
if (sourceList[i].lastModified() > targetList[j].lastModified())
{
newInSourceList.add(sourceList[i]); //ArrayList 1
}
else if(sourceList[i].lastModified() < targetList[j].lastModified())
{
newInTargetList.add(targetList[j]); //ArrayList 2
}
}
}
}
Thanks in advance.This minute is spent for the most part between the two points I mentioned below (Point A & B).
I guess time will especially isFile() calls. That should make a stat() system call, which calls the network file server.
If you can target Java 7 and greater, you can use the new java.nio.file and BasicFileAttributes. Allows you to extract the data to stat() each file in a single call, so that lastModified() and isFile() must separate calls to the file server. It will not yet be fast like lightning, but maybe almost 2 x faster - I think that all other treatments are overshadowed by calls on the network.
// Read file attributes to a list (or use a Map if you prefer) String files[] = new File(Directory).list(); BasicFileAttributes attributes[] = new BasicFileAttributes[files.length]; for (int n = 0; n < files.length; n++) attributes[n] = Files.readAttributes(Paths.get(directory, files[n]), BasicFileAttributes.class); // Now you can use attributes[n].lastModifiedTime() attributes[n].isRegularFile() // etc without each call hitting the file server. -
How to display the values of this query? The type is XDB. XDB$ STRING_LIST_T
Hi all
If I run this query using a tool like developer PL/SQL (SQL window), the values are displayed as a Collection. Just click and see the results of the al.

I want to know how to display these values using any tool of sqlplus (with dbms_output or something like that).
How can I do? With the help of the table? Create a type?

It would be a good idea also run the System File Checker tool to check that everything is correct in the system files.
"How to use the System File Checker tool to fix the files on system missing or corrupted on Windows Vista or Windows 7"
http://support.Microsoft.com/kb/929833
Use the (SFC.exe) System File Checker tool to determine which file is causing the problem and then replace the file. To do this, follow these steps:
- Open an elevated command prompt. To do this, click Start, click principally made programs, Accessories, right-click guest, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click allow.
- Type the following command and press ENTER:sfc/scannow
The sfc/scannow command analyzes all protected system files and replaces incorrect versions with appropriate Microsoft versions.

Optimize the performance of Windows 8.1
Hi all
I bought a HP Envy dv6 (including Windows 8) in November 2012.
For all those people who have good experiences with Windows 8.1... I was wondering what software you used to optimize performance?
In the past I had good experiences with...
Avast
Advanced System Care 6
CCleaner
IObit Malware Fighter
Driver boost
However, in Windows 8, it seems that some of them were because of issues with apps from metro. I had to reset my computer to factory settings countless times because for some reason any my metro apps can not maintain an INTERNET CONNECTION.
You guys are using any antivirus software or registry/maintenance software to optimize the performance of your PC which has not caused any problems? Leave the windows firewall "on" your best option for protection?
Chrome or Internet Explorer?
Make adjustments to settings PC (like the game "never notify" in the settings of the user account, etc.)?
What are some software 'must have' that you found useful?
Thanks in advance!
Hello!
Thanks for posting in the forum to Support HP and you thank for your trust in HP!
I'll try to answer some of your questions:
For all those people who have good experiences with Windows 8.1... I was wondering what software you used to optimize performance?
No, it works well on its own. Less you hit, the better. 3 party registry cleaners and optimizers should be used with caution by people with advance knowledge on the subject. More 3rd party (most, not all) optimizers are causing problems more than fix. Remove unnecessary programs, defrag automatically or auto (so HARD, not so SSD drive), run Disk Clean up, clear Temp folder.

These I wouldn't use one of them.
You guys are using any antivirus software or registry/maintenance software to optimize the performance of your PC which has not caused any problems? Leave the windows firewall "on" your best option for protection?
Light antivirus is ESET and clean of Windows Defender. Windows Firewall (firewall) is essential (critical) part of any system, computer security, network, so it must be turned on. To do this, * no * slow down your computer or your * network * traffic.
Being without firewall you leave at the open to pirate computer/malware attacks and risk huge data.
Antivirus software is also a kind of essential program to protect against known and unknown malware attacks. Windows Defender is integrated in Windows 8/8.1 if you don't like it, you can try ESET NOD32, Norton Antivirus...
Chrome or Internet Explorer?
They are both very light when it comes to performance. I personally chose IE 10 (my favorite - in win 7 and 8) and IE11. But that's my opinion. Use what suits you best. IE is very safe and stable in the latest versions of Windows. That is to say, I prefer because it is the 1st part, made from Microsoft and works.
Make adjustments to settings PC (like the game "never notify" in the settings of the user account, etc.)?
User account control is also very good part of the guarantee. In fact, it helps the principle of "least privilege" security and helps your programs to run with the least amount of law they can. I recommend that you use the value default level3 or the more level '4 always notify when. User account control can help you prevent malicious attacks / viruses / threats.
What are some software 'must have' that you found useful?
In my opinion, there is no such thing as software should be - everyone installs and uses what they need. Statistics show that most people (98% or more) use Microsoft Office. Many have some archivers zip/rar as 7-zip, video software like VideoLAN, etc... It depends on what you need. Antivirus software...

How to change the value games programmatically query in OFA
Hello
We have upgraded to 12.2.4.There is a custom value defined in 11i is also improved to R12 which is used in an FDF attribute and the FDF is used in a de FACTO forces (drop ship site) field in the sales form
Now the problem is this query value set has the following where would adopt with BLOCK. FIELD(:ADDR.) CUSTOMER_ID reference) that is compatible with Oracle Forms.But in R12, we use HTML frame, so the reference should be changed to dial the new code JAVA to UI in R12 customers.
Now, how we will discover the handle value contained query mdoify the query programmatically OAF or y at - it another way to deal with
where m.source_organization_id = FND_PROFILE. VALUE('ORG_ID')
and m.customer_id =: ADDR. CUSTOMER_ID
and m.subsidiary_inv_org_id = HCAS.org_id
and HCAS.status = 'A '.
and AHC. CUST_ACCOUNT_ID = HCA. CUST_ACCOUNT_ID
and HZP. PARTY_ID = HCA. PARTY_ID
Thank you
Prabhat
Hi AJ,.
I tried the first option and it worked. But instead of package, I created a profile and used in the query games value and then set the profile in the process request method.
Thanks a lot for the idea.
Kind regards

What is the name of this query
Hi all
I want to know the name of this query to learn about it, because I don't understand how it works.
Select the columns tab "(select table columns)" table.
I saw him, but I don't know how it works.
Thanks in advance
It is a scalar subquery expression.
"An expression of scalar subquery is a subquery that returns exactly one column of a line."
The value of the scalar subquery expression is the value of the select item from the list of the subquery.
If the subquery returns 0 rows, then the value of the scalar subquery expression is NULL.
If the subquery returns more than one line, then Oracle returns an error. »
See:
http://docs.Oracle.com/CD/E16655_01/server.121/e17209/expressions013.htm#SQLRF52093
For example, we can write
Select empno,
Ename,
DEPTNO,
(select dname dept where deptno = emp.deptno) dname
WCP
order by empno
/
Instead of
Select e.empno,
e.Ename,
e.DEPTNO,
d.DNAME
from emp e,.
d Dep.
where e.deptno = d.deptno
order by empno

How to improve the performance of the import
I'm converting a database of its current WE8ISO88591 character set AL32UTF8
I use NLS_LENGTH_SEMANTICS to TANK so I don't have to increase the length of the column.
I followed the instructions in the Oracle:
144808.1
313175.1
Except import that takes too long.
I took a full database export WE8ISO8859p1 and now its importation in AL32UTF8.
It is always difficult to prove slow source; but I think it has to do something with NLS_LENGTH_SEMANTICS. On the same
Server; If the new database was in WE8ISO8859P1, a 5 million row table import took 2 hours; but in Al32UTF8 with NLS_LENGTH_SEMANTICS it takes 1 day!
No idea how to improve the performance of the import.DOUBLE WIRE!
Please, don't post duplicate discussions.
Mark this thread ANSWER and continue to use your original thread where you are already helped.
You have NOT given the info that has been ask in your other thread.

How much RAM you have. If it's 4 GB or less, you may need to upgrade. 8 GB would be excellent although Apple suggests much less.

What is the best way to improve the performance of this all-in-one PC?
Thanks in advance.
David Barrett.
Here are a few methods:
- Run msconfig.exe, and then uncheck the startup tasks that you don't need. No matter what you disable, Windows always starts.
- Use a light virus scanner, for example Microsoft Security Essentials.
- Replace your magnetic drive with a Solid State Disk (SSD)

What can I do to prevent the failure of this query
Someone used our search engine to submit the search term "NT the Australia".
With the help of Barbara in several positions before this one, we have a thesaurus that transforms "NT" in "Northern Territory".
If the "analysis function" I wrote eventually transform the search of this query string:
But which causes this error:select * from search_table where contains(keyfield,'(nt|northern territory) and (australia)')>0
-20000:ORA - 20000: Oracle Text error: DRG-10800: failed to query:
I assume that the problem is "NT", which is taken to mean 'short term', rather than the State abbreviation. The same type of problem that can occur when someone searches for BT, which means 'British Telecom', but I imagine that this will be interpreted to mean "generic term".
What is the usual way to stop these kinds of questions? I can write the code that replaces "NT" by "northern territory" before I even touched my dictionary of synonyms... but if I'm going to hardcode things like that, what else I'd be worried? And although I could replace 'BT' by 'british telecom', I imagine that anyone who wants to seek 'the confidence of bankers' could have a surprise if I.
Is it all consistent, sensible, ways to deal with this kind of issue that does not imply that users think reading the spirit?"You say, I think, it was a stupid move and that there is no harm in putting each search term all about braces? "'({WOMAN}) and (HAT {})' would be just as acceptable, as fast as the '(femme et chapeau)? »
Fix.
