Problem with the order of colums in query

Hi!
We work with SAP 2007 and patch 44. When we want to do a query, in the result, the colums aren't in same order that I have defined in the query.
Someone have already met the same problem?
Thank you to take in consideration my problem
Best regards,
Séverine

Hi Séverine,
Most new PL for 2007 has this problem. Hope the fix could be coming soon.
BTW, do you have the same problem when you run the saved query?
Thanks,
Gordon

Problems with the order

once more I have problems with the order in iTunes:
Titel number 8 is on top and the first one is on place 10. The only difference in the information is
Titel number 8 has titel number 8 and the titel on place 10 has the titelnumber 1, all the other informations are eqaul..
See the screenshots:

applewoi wrote:
the album has got 17 files in 2 CDs. Shall I write therefore
Titelnummer
1 von 17
2 von 17
and so on?
all in 1 CD
I suggest you set
CD-Nummer
1 von 2
2 von 2
Then the tracks
CD-Nummer 1
Titelnummer
1 von 9 (or however many tracks there are per CD)
2 von 9
CD-Nummer 2
Titelnummer
1 von 8
2 von 8

Problem with the order of inserted PDFs...

I work with archiving records in chronological order and am having problems getting the files to insert correctly. When I go to insert files, everything is fine when only one file is being inserted. Also what works fine is if I'm trying to insert multiple files that are already in order (by using the Shift key to select them all at the same time) - i.e. file1, file2, file3 - and I know that I can select the last one first to invert the order - i.e. file3, file2, file1. The problem I'm having is if I'm trying to insert file3, file1, then file2 without having to do multiple insertions. Obviously this isn't a issue when dealing w/ 3 out of order, but not 10+. I have tried using the Control key to select them in order but the order is ALWAYS messed up when I hit OK.
Thanks to anyone that can solve my problem.

Don't think there is anything you can do about that, unless you write a script or something. The ordering is typically set by the way they appear, not the order you select them. Some people have more success dragging from Explorer into Acrobat, rather than using insert pages. However, you are still stuck with the order the of the files in the window, not the order you select them. To the best of my knowledge, there is no way to change this behavior. Using a script are such is the only way I can think that what you want might be done.

How to fix a problem with the order of strings in a JSON response for a CFHTTP request?

Good morning, guys! (It's 10:50 a.m. in Brazil)
First of all, I'm still new at CF and my questions may seem too much silly and my English's not the best, so, please be patient with me. hehe
Well, I'm accessing a link via CFHTTP that gives me a JSON response. I'm not familiar with JSON yet, so I'm working it as a string and using string functions (Find,RemoveChars,Replace,etc), but it happens to me that I'm receiving a certain kind of order of the strings list from the JSON when I access it directly from the browser and other kind of order totally different when I access it from the CFHTTP.
I only figured it out because I was working at home with my code and there everything went just fine as expected. Then I brought to my job to develop a little bit more as soon as I get a free time and here my code doesn't work anymore. When I took a look at the JSON by a CFOUTPUT, I realized the strings were in a different order.
Does anyone know why is it happening?
Link to the JSON: http://sigmine.dnpm.gov.br/ArcGIS/rest/services/extra/dados_dnpm/MapServer/0/query?text=83 0620/2012&geometry=&geometryType=esriGeometryEnvelope&inSR=&spatialRel=esriSpatialRelInter sects&where=&returnGeometry=true&outSR=&outFields=FID,Shape,PROCESSO,ID,NUMERO,ANO,AREA_HA ,FASE,ULT_EVENTO,NOME,SUBS,USO,UF&f=pjson
Basic code simplified to find out that the order of strings were coming different when access by CFHTTP:
<cfhttp url="#URLAbove#" method="get" result="DadosDoDNPM" charset="utf-8" timeout="10000" />
<cfset DadosJSON = deserializeJSON(DadosDoDNPM.FileContent) />
<cfif arrayLen(DadosJSON.features)>
<cfset CodigoFonteJSON = ToString(serialize(DadosJSON.features)) />
<cfoutput> #CodigoFonteJSON# </cfoutput>
</cfif>
Is there a way to fix it and to make my code work everywhere?
If it matters, I use Railo at home and at my job.
Since now, I thank you.

When you deserialize JSON data, ColdFusion converts it into native structures and arrays (roughly equivalent to JavaScript objects and arrays). In ColdFusion, structures are unordered (that is, they don't maintain keys in any particular ordered sequence).
This really shouldn't be a problem though, at least not if you just want to work with the data contained in the deserialized JSON structure. So DadosJSON should be a native ColdFusion structure, and you can interact with it like any other structure in ColdFusion. In fact, you should not have to re-serialize it at all unless you need to send it to an external application using JSON.
Why are you reserializing the data? And why use serialize() instead of serializeJSON()?

Problem with the order of the columns of a ALV

I have a problem with a ALV, variants we keep this ALV does not record the order of the columns
Thank you

I suppose you want to change the sequence of columns of a ALV. If you can change it by clicking 'settings' of right-top corner of ALV. After done you can save the new settings into a new. If you find some abnormal behaviour, please check the settings by WDA component "wd_analyze_config_user".
FYI.

IOS 5, iPhone 4 - Problem with the order playlist

Helleo!
I have my iPhone 4 instaled the iOS 5.
In the "Music"-App is the order of the Playlist not korrekt.
Please help me...
best reagrds
R.

So the power button and home key when pressed solo do nothing? But, when you press them together it'll take a screen shot? If you're still stuck in the settings screen I would go to (from main settings page) General > Reset > reset all settings. If that does not fix the issue then import pictures and transfer purchases to computer, back it up in either iTunes or iCloud and restore the device. Setup as new and test the device. If issue persists just call AppleCare and have it replaced. But this ultimately sounds like a software issue and not hardware.
Beware of what you download. Yes Apple screens all applications prior to allowing them in the AppStore but there are a ton of apps out there that will have adverse affects on your device.

PROBLEM WITH THE PHONE ORDERS

Hello,
Is there a problem with the orders which are done with an international credit card? I am asking this because my brother and I have been trying to place an order to buy Macbook Pro with Retina Display for 2 days.
We placed 2 online orders with my international credit card. In each order I inputted the international address provided by the Bestbuy web site(10780 Kempwood Dr. - Houston, TX 77043) to the billing address. And I inputted my brother's address in the US to the shipping address. Each time, at first,orders were accepted but after 1 minute we received an email that indicated orders were cancelled. Customer service told me that the shipping address and billing address on my order are same and there might be an issue on the system that causes this problem and suggested me to place the order over the phone. I replaced the order over the PHONE(WITH SALES DEPARTMENT) but again I received two emails, one of them is "We received your email" and the other one is "Your order has been cancelled".You can find the reason of the cancellation in the email below;
We're sorry, but an item on your order placed on June 12, 2014 has been canceled because we were unable to verify your information.
I am really tired of that,it is like a joke.
An authorized person should answer this; does BestBuy accept international credit cards or not?

Hello nbilgin,
Placing orders on BestBuy.com should be both exciting and easy, and I'm disheartened to read that you've run into these difficulties in trying to purchase your new Macbook Pro. Surely, this is not the experience that we strive to provide and I regret very much that you've been disappointed.
Using the information you provided when you signed up for our Community. I was able to locate your orders. I am investigating the situation now and as soon as I have additional details, I will let you know. I'm sorry that I must impose on your patience and good nature in the interim; I should have more details shortly.
I'm very grateful that you wrote to us about this situation.
Sincerely,
John|Social Media Specialist | Best Buy® Corporate

There was a problem with your order please call?

My wife ordered a 4S 32GB black model and was putting me on her plan of currently 2 phones. We ordered via the site about a week ago and got the message the phone would ship 11/30, added a data plan etc on a 3rd separate line. Received an order confirmation, but couldnt use the 6-7 digit order number to check on it kept saying no order. Today she checked and said she received soemthing from Verizon saying there was a problem with the order and to either call or email them. She's at work til 4p EST time but was curious if anyone else got this and what it could cause this message?
On a separate note I have my own plan with a iPhone 4 that I was going to cancel and move to her plan porting my number but the order wouldnt permit a port of a verizion number. I called and the rep swore there would be no cancellation fee (sounds fishy to me) but he had someone else look and they said there was no cancellation fee either. I dont know if the order flow recorded that and they are question it or something else is going on.
Any ideas on why Verizon would have a problem with the order would be great! Thanks!

As far as the porting of your line to your wife's account...you might want to go in to a local store to handle that. I don't think it would be a port in the traditional sense...but a swap of responsibility...meaning your wife would take ownership of your line. I will have to do that soon for one of the lines under me so that the person using it can have it in their name. In that instance, there would not be any cancelation fees because the line isn't being canceled. The account ownership is just being taken over by someone else and they would take over the remainder of the contract.
As far as the issue with the order...if your wife makes you an authorized manager on the account you would be able to call in and discuss whatever is happening. The issue could be a number of things so it's hard to tell you what it could be. It's also possible that there isn't an issue at all and the problem is just that the system isn't recognizing the order number.

Problems with Calendar order from iPhoto

I've tried twice to create a calendar out of iphoto and I've gotten a response via email after several days that there was a problem with the order:
Apple discovered an issue with the file you submitted. It appears the
calendar has small month names. As a result, Apple is unable to process
your order and you will not be charged.
We recommend updating your software, changing the theme on your print
product, then changing it back to the original theme.
Once completed, preview your print product in iPhoto, and place the
order again.
For instructions on how to update your software, refer to:
Mac OS X - Updating your software
<http://support.apple.com/kb/ht1338>
For instructions on how to change your theme, refer to:

<http://support.apple.com/kb/HT1040>
We appreciate your business and apologize for any inconvenience.
There are no updates for my OS or iPhoto. I changed themes and went back to the original (and had to rebuild it all over again, grrrr). Any ideas what could be causing this?
So much for getting these for Christmas presents. Thanks!

Dear Martha,
I had the same problem, and this bug in iPhoto cost me my yearly christmas presents for all of our families (grandparents, aunts, uncles etc.)
By digging through this forum, I found the solution that actually worked for me.
But I will not order the calendars from Apple because they cancelled the calendars three times without telling me what the problem was, and endless and numerous calls with different support people at Apple gave no solution.
I will now export PDFs and send them to a different service.
Maybe in your case there is another project.db file?
Sometimes, when iPhoto rebuilds databases, it seems that it creates a second one.
(I read it here somewhere in the forum - so I hope this could be a good hint to follow)
All the best,
Martin

I just order 8 calendars from iPhoto and they came to me fine. Now I need to order two more but when I go thru the process I get a message saying:unable to assemble calendar. There is a probleme with the photo with the file name"(Null)" more........ .

Would someone be able to explain to me the following issue with Iphoto?
I ordered 8 same calendars for my soccer team and received them fine. Although a couple of pictures on it are a little off (out of focus). I need to order two more of the same calendars but when I go thru the process ireceive an error message saying:
"Unable to to assemble calendar" There is a problem with the photo with the file name "(Null)" The full resolution version of this photo either cannot be located or is corrupt. Please replace this photo or delete it from your calendar.
How can I fine this "corrupt" photo? How did it go thru with the first batch of calendars but won't go thru now?
Thank you for your help.

Apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start
with Option #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

 go.
It was executive correctly.
I was taken another sequence container. In the sequence container iam creating one executive sql

Please help me

Arthur suggestion works but you shouldnt even be doing this on a SQL Task.
Use a data flow task. You'll have better control over the data that is being transfered and get better performance because no staging table will be used.
Just because there are clouds in the sky it doesn't mean it isn't blue. But someone will come and argue that in addition to clouds, birds, airplanes, pollution, sunsets, daltonism and nuclear bombs, all adding different colours to the sky, this
is an undocumented behavior and should not be relied upon.

Problem with the hierarchial fields in a Purchase order xml report

Hi,
I am having a problem with the hierarchy problem. We are populating attribute 15 of a PO header. some times it can be null. FYI, we are using 11.5.10 instance where oracle supports direct PO template rather than having a rdf file.
And now in the xml report, if attribute15 of po header is not null then it is fine.
But if attribute15 is null, then the template is picking from the next available attribute15 that is from the po lines. As the line level group of "LINES" is between the "PO_DATA" (header group), hence the template is checking for next available attribute15.
Can any one please suggest how to design the template where we can make the template to check only for that tag at the header level group rather than the line level group tag?
Thank You in advance.
Regards,
Srinivas.

Problem with the cache hit ratio

Hello,
I ma having a problem with the cache hit ratio I am geting. I am sure, 100% sure, that something has got to be wrong with the cache hit ratio I am fetching!
1) I will post the code that I am using to retrieve the cache hit ratio. I've seen about a thousand different equations, all equivalent in the end.
In oracle cache hit ratio seems to be:
cache hits / cache lookups,
where cache hits <=> logica IO - physical reads
cache lookups <=> logical IO
Now some people use the session logical Reads stat, from teh view v$sysstat; others use db block gets + db consistent gets; whatever. At the end of the day its all the same, and this is what i Use:
SELECT (P1.value + P2.value - P3.value) AS CACHE_HITS, (P1.value + P2.value) AS CACHE_LOOKUPS, P4.value AS MAX_BUFFS_SIZEB
FROM v$sysstat P1, v$sysstat P2, v$sysstat P3, V$PARAMETER P4
WHERE
P1.name = 'db block gets' AND
P2.name = 'consistent gets' AND
P3.name = 'physical reads' AND
P4.name = 'sga_max_size'
2) The problem:
The cache hit ratio I am retrieving cannot be correct. In this case i was benchamarking a HUGELY inneficient query, consisting of the Union of 5 Projections over the same source table, and Oracle is configured with a relatively small SGA of 300 MB. They query plan is awful, the database will read the source database table 5 times.
And I can see in the physical data statistics of the source tablespace, that total Bytes read is aproximatly 5 times the size of the text file that I used to bulk load data into the databse.
Some of the relevant stats, wait events:
db file scattered read 1129,93 seconds
Elapsed time: 1311,9 seconds
CPU time: 179,84
SGA max Size: 314572800 Bytes
And total bytes read: 77771964416 B (aproximatly 72 Gga bytes)
the source txt loaded to the database was aprox 16 G
Number of reads was like 4.5 times the source datafile.
I would say this, given the difference between CPU time and Elapsed Time, it is clear that the query spent almost all of its time doin DB file scattered reads. How is it possible that i get the following cache hit ratio:
Cache hit Ratio: 0,92
Cache hits: 109680186
Cache lookups: 119173819
I mean only 8% of that Logical I/O corresponded to physical I/O? It is just not possible.
3) Procedure of taking stats:
Now to retrieve these stats I snapshot the system 2 times. One before the query, one after the query.
But: this is not done in a single session. In total 3 sessions are created. One session two retrieve the stats before the query, one session to run the query, a last session to snapshot after the query.
Could the problem, assuming there is one, be related to this:
"The V$SESSTAT view contains statistics on a per-session basis and is only valid for the session currently connected. When a session disconnects all statistics for the session are updated in V$SYSSTAT. The values for the statistics are cleared until the next session uses them."
What does this paragraph mean. Does it mean that the v$sysstat only shows you the stats of the last session that closed? Or does it mean thtat v$sysstat is increamented with the statistics of each v$sessionstat once a session terminates? If so, then my procedure for gathering those stats should be correct.
Can anyone help me sort out the origin of such a high cache hit ratio, with so much I/O being done?

Hi,s
first of, let me start by saying that there were many things in your post that you mentioned that I could no understand. 1. Because i am not an Oracle Expert, i use whatever RDBMS whenever i need to. 2. Because another problem has come up and, right now, i cannot inform myself to be able to comprehend it all.Well, could it be that you need to understand the database you are working on in order to comprehend it? That is why we strongly advise you to read the concepts manual first, you need to understand the architecture that Oracle uses, as well as the basic concepts of how oracle does locking and maintains read consistency. It does these different than other database engines, and some things become nonsense if looked at from the viewpoint of a single user.

First, the query code:

Now, Althought it is clear from the query that the statement is executed with the NOLOGGiNG, i have disabled the logging entirely for the tablespace.There are certain rules about nologging that may not be obvious. Again, this derives from the basic Oracle architecture, and if you use the wrong definitions of things like logging, you will be led down the primrose path to confusion.
>
Futhermore, yes, the RDBMS is a test RDBMS... I have droped the database a few times... And I am constantly deleting an re-inserting data into the source database table named PROFILE.>
I also make sure do check all the datafile statistics, and for this query the amount of RedoLog, Undo "Log", Templife used is negligible, practically zero.Create table is DDL, which has implied commits before and afterwards. There is a lot going on, some of it dependent on the volume of data returned. The Oracle database writer writes things out when it feels like it, there are situations where it might just leave it in memory for a while. With nologging, Oracle may not care that you can't perform recovery if it is interrupted. So you might want to look into statspack or EM to tell you what is going on, the datafile statistics may not be all that informative for this case.

Most of the I/O is reading, a few of the I/O is writing.
My idea is not to optimize this query, it is to understand how it performs. Well, have you read the Concepts manual?
I have other implementations to test, namely I having trouble with one of them.
Furthermore, I doubt the query Plan Oracle is using actually involves tablescans (as I I'd like it to do); because in the Wait Events, most of the wait time for this query is spent doing "db file scattered read". And I think this is different from a tablescan.Please look up the definition of [db file scattered read|http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/instance_tune.htm#sthref703].

Do you really have to use sessions external to the query session ? Can you query v$mystat joined to v$statname from the session itself.
No, I don't want to that!
I avoid as much as possible having the code I execute being implemented in java. Why do you think java has anything to do with this? In your session, desc v$mystat and v$statname, these are views you can look at.
When i can avoid it I don't query the database directly through JDBC, i use the RDBMS command line client, which is supposed to be very robust. Er, is that sqlplus?
So yes, I only connect to the database with JDBC... in very last session.
Of course, I Could Have put both the gather stats before query and gathers stats after query a single script: the script that would be also runing the query.
But that would cause me a number of problems, namely some of the SQL i build has to be implemented dynamically. And I don't want to be replicating the snapshoting code into every query script I make. This way I have one sql with the snapshoting scripts; and multiple scripts for running each query. I avoid code replication in this manner.Instrumentation is a large subject; dynamic sql generation is something to be avoided if possible. Remember, Oracle is written with the idea that many people are going to be sharing code and the database, so it is optimized in that way. For SQL parsing in particular, if every SQL is different, you get a performance problem called "hard parsing." You can (and generally should, and sometimes can't avoid) use bind variables so that Oracle doesn't need to hard parse every SQL. In fact, this is one of those things that applies to other engines besides Oracle. I would recommend you read Tom Kyte's books, he explains what is going on in detail, including in some places the non-Oracle viewpoint.

Furthermore, Since the database is not a production database, it is there so I can do my tests. I don't have to be concerned with what other sessions may be doing to my system. There are only the sessions I control.No, there are sessions Oracle controls. If you are on unix, you can easily see this, but there are ways to see it on Windows, too. In some cases, your own sessions can affect themselves.

then what it the array fetch size ? If the array fetch size is large enough the number of block visits would be similar to the number of physical block reads.
I don't know what the arraysize you mention is. i have not touched that parameter. So whatever it is, it's the default.You should find out! You can go to http://tahiti.oracle.com and type array fetch size into the search box. You can also go to http://asktom.oracle.com and do the same thing, with some more interesting detail.

By the way, I don't get the query results into my client, the query results are dumped into a target output table.
So, if the arraysize has something to do with the number of rows that Oracle is returning the client in each step... I think it doesn't matter.You may hear this phrase a lot:
"It depends."

As for the query plan, If i am not mistaken you can't get get query plans for queries that are: create table as select.What?
JG@TTST> explain plan for create table jjj as select * from product_master;
Explained.
JG@TTST> select count(*) from plan_table;
COUNT(*)
 3
I can however commit the create table part and just call for the evalution of the Select part of the query; i believe it should be same.
"Optimizer" "Cost" "Cardinality" "Bytes" "Partition Start" "Partition Stop" "Partition Id" "ACCESS PREDICATES" "FILTER PREDICATES"
"SELECT STATEMENT" "ALL_ROWS" "2563" "586110" "15238860" "" "" "" "" ""
"UNION-ALL" "" "" "" "" "" "" "" "" ""
"TABLE ACCESS(FULL) SONO99.PROFILE" "" "512" "117222" "3047772" "" "" "" "" ""
"TABLE ACCESS(FULL) SONO99.PROFILE" "" "513" "117222" "3047772" "" "" "" "" ""

This query plan was taken from sql developer, exported to txt, and the PROFILE table here has only 100k tuples.
Right now I am more concerned with testing the MODEL query. Which Oracle doesn't seem to be able any more... but that is a matter for another thread.
Regarding this plan. The Union ALL seems to be more than just a binary Operator... IT seems to be Neray.
The union all on that execution plan seems to be taking as leaf tables 5 99sono.Profile tables, and be making a table scan to them all. So I'd say that the RDBMS should only scan each database block once and not 5 times.
But: It doesn't seem to be so. IT seems like what oracle is doing is scanning completly each the table, and then moving on to next select statement in the UNION ALL. Because given the amount of source table that was read, 5 times greater than the size of the source table. Oracle didn't reuse read blocks.
But this is just my feeling.Your feeling is uninteresting. Telling us what you really hope to accomplish might be more interesting.
Anyway, in terms of consistent gets, how many consistent gets should the RDBMS be doing? 5
One for each table block?It depends.
