External table with the empty file
Hello
My version of db: Oracle 11 g
I have a csv file that is empty.
I created an external table the empty csv file.
When I run:
Select count (*) in the externaltblname;
It returns 1.
It should return 0 to the right.
In the definition, I specified "SKIP 1.
But he always returns 1.
When I use this external table to load into a table target. It loads a single row with null values.
How to solve this problem. Please advice.
What works for me is the following (t_ext points to a blank csv):
SQL > select count (field) in the t_ext;
COUNT (FIELD)
------------
1
1 selected line.
SQL > select ascii (field) in the t_ext;
ASCII (FIELD)
------------
13
1 selected line.
SQL > select count (replace (field, chr (13))) of t_ext;
COUNT (REPLACE (FIELD, CHR (13)))
-----------------------------
0
1 selected line.

External table with the preprocessor file to display the list of files
Hello
in my db 11.2.0.2 I would create an external table with script preprocessor to show me the list of files in a directory.
Preprocessor banally:
#! / bin/bash
CD/MyDir
/ bin/ls-l *.txt 2 >/dev/null
The problem is the file name that contains white space (style windows in a Linux env), for ex:
-rw - r - r - 1 oracle oinstall 920 9 Jun 17:37 File1.txt
-rw - r - r - 1 oracle oinstall 72316 Jun 10 10:37 file GC output1.txt
-rw - r - r - 1 oracle oinstall 72316 Jun 10 10:40 GC file output2.txt
So I can't use FIELDS DELIMITED BY "". ""
FIXED size? No, because the file size change the length of the lines.
I tried to use awk in my preprocessos script, but I have the same problem:
/ bin/ls-l *.txt 2 >/dev/null | / bin/awk ' {printf "%s %.2d %s %s\n", $6, $ 7, $ 8, $9} '.
Any ideas?

External table - load a log file with more than 4000 bytes per column
Hello
I'm trying to import a log file into a database table that has a single column: txt_line
In this column, I'm trying to fill out a log by record type entry. Each log entry is normally more than 4000 bytes in the outer table, it should be a clob.
Below is a table of external work that works, but cut all entries after 4000 bytes. How is it is possible to directly load the data into a clob column? All I've found are descriptions where I have a clob-file by file.
Any help is appreciated
Thank you

problem with the Finder - files and folders displaying incorrectly
After acquiring a new iMac, I noticed a problem with the Finder - files and folders are displayed wrong (see table).
This is what happens always after the files have been transferred from one folder to another. I was reminded of my days of using Mac OS in the 1980s when automatic setting of files was not so "automatic." I use Mac OS for decades and I don't remember the last time I had to think about GUI problems like that.
Other problems in the graphical display of files and folders were introduced, such as when you have hundreds of files in a single folder, you end up deleting about 30 to 40 of them say in a particular section, and you end up with gaps of the ChartSpace where files used to be, that is the remaining files automatically rearrange themselves (fill in these gaps) - never. A week later, you open the folder, and the gap of GUI is still there.
I decided to do a clean install of the operating system but nothing works.
Is there some setting in Prefs I'm missing?
Hi there highland99,
Looks like your folder icons are not accommodating themselves automatically you plan to do. To me, this indicates that you have organize by the None value in the view menu. You can change the way files and folders are prepared automatically by clicking on view > reorganize by and selecting how you would like that fixed.
Thank you for using communities of Apple Support.

Is it possible to store parameters to script with the InDesign file?
Hello
I have a crazy idea: it is possible to store parameters to script with the InDesign file?
In this case the Scripting Guys will be able to store these settings with the file, and when the script runs - he can check if those setting exists - if so - script can run without showing the dialog with the settings... (like all the necessary parameters are stored with the indesign file), and of course we can force InDesign to display the script dialog parameters if run us with the alt/option key pressed when executing this script. Maybe even different scripts will be able to share these settings and interact with each other... We will be able to have the settings will be saved with the file, or temp settings for the document assets or session (till InDesign is closed). With eventListeners and commissioning, scripts, that we will be able to make scripts that would be able to check updates and automatically run when we placing images and text and so on... This can be a set framework of InDesign scripting, allowing to write scripts that use ui and same libraries so we don't have to write everything from scratch every time and just included required libs...
So here are 2 great questions for now:
(1) is it possible to store script with .indd file settings
(2) who is interested in creating InDesign scripting (because it only makes sense if it will use a lot of people)
PS: I know that it is possible to store settings in an external file, but this time, I'm interested only to save the params with .indd

OSB file work twice with the same file
I have a problem of execution of a proxy service that get the files from a file system. Everything in the flow works as expected, but at some point, I have to wait for an update on a database and the process awaits for this change. Everthing is normal if the update comes in the following minutes 1 - 7, but after that, if the process is always there in general (9-11 minutes), a second process is called and the processed file is the same. After the first process is called the folder is empty, so I don't understand why the proxy is called again with the same file, since there is nothing on the record. This can happen because I have make changes to the database.
The process is called only twice with the same file, no process is still called (a third) If two processes still work, which is weird. given that nothing in my logical proxy back to the beginning.
"Weblogic/OSB" tends to release resources on a specific time, such as 'Max Stuck Thread Time' but for files or other resources?
No idea why this is happening
Thanks in advance.I think it is due to the delay of transaction. The PolledMessageListenerMDBEJB under file carrier has a timeout of the transaction of 10 minutes. So if you encounter a very long-lived transactions that spans more than 10 minutes, you could see the price drop that passes due to the delay.
To confirm, is this is the case, when this problem occurs, go to JMS Modules > jmsResources > wlsb.internal.transport.task.queue.file_auto_n > Monitoring. You should see messages in the messages waiting in the column.
Click to view the Messages. Click on a message and check the number of delivery. This should have a value of 1 or more which should mean the message has been restored at least once before.
If this is the case, you can try changing the value of timeout PolledMessageListenerMDBEJB transaction under file Transport provider in deployments and then update the deployment of file transport provider. Check in parallel with support on what is the official recommendation to increase the time-out period.

Re-import L/r &; battery with the original file?
Re-L/r & battery with the original file import
Hi, need some help please.
After have exported them to an external editor for re - I want to import the image in lightroom, when I click on this option, prior to export (in re - import), it merely to send the image to the original folder not in the preview pane the long side of the Photo original/s and L/R so if I want to work on this, once again , I open the L/R folder and drag it into an external editor.
I've been under DISPLAY/SORT but don't no if any option to choose here.
Hope you understand the question
Thank you
RussSorted
If image does not appear in Lightroom, check that the Source film indicator and the menu does not appear "previous import." If you have switched to "Previous import", access the menu, and then select all photographs.

Creating external Tables using the EXECUTE IMMEDIATE in PL/SQL
Hi guys,.
I am trying to create an external Table using the EXECUTE IMMEDIATE in a procedure and I managed to compile and no errors were generated. But when I try to run it from sql using the exec command I get the following error:
------------------------------------------------------------------------
ERROR on line 5:
ORA-00911: invalid character
ORA-06512: at "GEO. TEST_DDL', line 4
ORA-06512: at line 5
-------------------------------------------------------------------------
I tried to check the whole statement to create the external table, but I can't find where is the error. Surprisingly, if I simply run the command table create external on sqlplus it works, but not a procedure.
If anyone can help with ideas or experience?
Geoffrey KossamiThe error means that there is an identifier somewhere that starts with a nonalphanumeric. This is a typical mistake of editing. A procedure compiles correctly is not of course because the underlying dynamic sql running is OK. Which of course only be resolved when you try to run it.
There is certainly a problem with the text you provide to be run as a piece of dynamic sql code. You should try to watch it with dbms_output and run this code in sqlplus. But your problem is with the code you run as dynamic PL/SQL, it is not itself compilable.

CSS Display table with the bottom border only
Hi all
I'm very bad in CSS, I seriously need a style.
I want the table with the bottom border only
I tried like
< table frame = "below" cellpadding = "2px" cellspacing = "0" style = "overflow: scroll;" empty-cells: show; border: 1px solid #285577; "width ="350px"> ';
but frame = 'below' does not work with IE - 7
Please could give me a solution.
Thanks in advance
Good bye
Sonny_starckSonny_starck,
I don't know what kind of table you need exactly but
< table style = "" border-bottom: 1px solid #285577; ">"
should do the job.

kindly tell how to use the unique value of a table with the index 0
Hi
Yep, use Index Array as Gerd says. Also, using the context help (+ h) and looking through the array palette will help you get an understanding of what each VI does.
This is fundamental LabVIEW stuff, perhaps you'd be better spending some time going through the basics.

Which programs are associated with the xcm files
I found a folder in my folder system program (. 86) that I don't know or I don't know where it comes from. It has a bunch of XCM file in the known folder that cannot open my own computer, can not give me info on how to open and cannot tell me which of my programs, he joined. I want to delete it because it seems that a suspect case, but not because I can not check programs what or how much it may or may not be associated with.
Sincerely yours, Aaron Baker.Take a look at this link:
http://pcsupport.about.com/od/FileExtensions/f/xcmfile.htm
Excerpts .....................................
What is the .xcm file?
Response: A file with the XCM file extension is a Concept exported CmapTools mapping file.
How to open a XCM file:
The easiest way to open a file XCM is double-click on it and let your PC decide which default application should open the file. If no program opens the XCM file then you have probably an installed application that can view and/or edit files XCM.
