Characters not visible (caused by hitting the bar space or TAB in PL/SQL developer tool) causing slow running query? and database with low performance?

Hi all

I need your help to get this issue resolved its urgent and I'm not able to get to the conclusion. Here is my scenario, I'm getting slow query runs because of some non-visible characters that are copied with the application of the PL/SQL developer tool. Please find below attached screenshot: Oracle_Issue

Oracle_Isssue.png

Note: This non-visible characters are caused when we write the query then us hit the SPACEBAR or press TAB PL/SQL developer tool

I use the developer tool PL/SQL to write or test the query. Now I take this request copy paste in my application of the company (who takes this query connects to Oracle or any source of data base, catch data and produce PDF reports for customers).

Now, my client is the Oracle user when I write and you run this query by the PL/SQL Developer, it works fine, but when I paste in my Inbox feature request (reporting system) and run it, it runs slower and jams to the customer database. Now after a little research I found that when I copy the query directly from PL/SQL developer at my request, he copy some characters not visible (introduced when we press SPACE or TAB in PL/SQL developer tool when writing query) with the request, then I copy this query again to my box of the application Notepad and delete these non-visible characters. Now, after removing the non-visible characters again once I copy backup question in my application and run the query, it works normally. Please find below attached screenshot: Oracle_Issue 2

Oracle_Isssue_2.png

So I think that the cause of slow performance is due to some INVISIBLE CHARACTERS present in the query.

My application uses SQL server 2008-2012 at the backend to store data from different sources.

Character set used: SQL_Latin1_General_CP1_CI_AS


To write and test queries: PL/SQL developer tool

My Client use Oracle 11 g

Character set used: Normal character: NLS_CHARACTER: AL16UTF16

National Characeter: NLS_NCHAR_CHARACTER: WE8WIN1521

I just wanted to know the blocking process to the top of the database and the characters not visible how affecting slow running query of query database.

Please let me know if I'm missing something or you need more information on this issue.

Thanks in advance,

HP

Simple answer. No.

Spaces and line breaks do not change the execution plan created. Does not plan to run slower or faster.

  • Why, the views have a tab constraints in SQL Developer 4.0.3 or 4.1.0?

    I create constraints on views all the time now to improve performance when you are working on a dblink, but I can only confirm the looking at the DOF tab. shouldn't it be a tab constraints as tables have? After all, it has a triggers for the views tab.

    Compared to this, should not be an option to right click in the window connections for stress and relaxation on views as there are Tables?

    Try to follow these steps:

    1. in the database table to add the new column "JOIN_COLUMN" and add the new sequence "JOIN_SEQ".

    2. Add this new column in the entity object. (You can add this in entity object by right clicking on the entity object and then select "Synchronize with database" then the new column and press on sync)

    3. in your bookmark create button to create only one line NOT 2 rows.

    4 - Open the object entity--> java--> java class--> on the entity object class generate and Tick tick on the accessors and methods of data manipulation

  • Version 6.0 of Windows Mail in Windows Vista does not all emails that hit the server.

    Hello

    I use Windows mail, version 6.0.6000.16386. for Microsoft Vista.

    It seems tht that not every email will make it through Windows mail. I checked with my internet provider and we can see the e-mails hit the server, but it was as if Windows mail has been picking up a choice than to receive mails.

    When we access the server directly, it seems to work. Anyone can help?

    Thank you.

    Simply select the account under Tools | Accounts | Mail, then click on remove.  You will need to know the parameters to set it up again.  McAfee is known to cause problems with Windows Mail.  You will not be able to correct them if you continue to use McAfee.  Alternatively, you can try to compact and repair the database of WinMail to see if that helps (see www.oehelp.com/WMUtil/).

  • CR2 files not visible as thumbnails in the Picture Viewer or Windows Photo Gallery.

    I was using an Acer laptop for a long time, and I was transferring files from my Canon T3i CR2.  I was able to view these files as thumbnails.  I recently bought a new computer, an HP Z220.  For some reason after that I have transfer files to the Z220, I am unable to see these pictures as thumbnails, which is very annoying when I know there is a special move, I want to watch.  Without a thumbnail, I have to open each file in the Canon software, which can be quite tedious.  How can I fix?  Is there a file on the old computer, which was developed without the knowledge of me, perhaps by default, but is setting a different setting now on the HP?  Two computers use Windows 7.  Has anyone else had this problem?

    Problem: I was using an Acer laptop for a long time, and I was transferring files from my Canon T3i CR2.  I was able to view these files as thumbnails.  I recently bought a new computer, an HP Z220.  For some reason after that I have transfer files to the Z220, I am unable to see these pictures as thumbnails, which is very annoying when I know there is a special move, I want to watch.  Without a thumbnail, I have to open each file in the Canon software, which can be quite tedious.  How can I fix?  Is there a file on the old computer, which was developed without the knowledge of me, perhaps by default, but is setting a different setting now on the HP?  Two computers use Windows 7.  If anyone has had this same problem?

    I wanted to come back here and to answer my own question, as I found the solution in a very short time. I went on Canon's site and downloaded a codec RAW update.  After installation, I was able to view CR2 (RAW) files on the newer computer.  I found the update through various research, after that I reduced the problem of the relationship between Canon's Digital Photo Professional and Windows Photo Gallery.  Maybe when I was using the Acer laptop, I had already downloaded the drivers updated to the DPP and he did not know or just do not do.  I do not know.  The thing is, while searching for an answer to this question, I found others have had the same problem and need a solution.  The short answer: you need to update the codec for Canon Digital Photo Professional RAW.  Here is a link to the download.

  • Disk management does not allow me to partition the unused space

    When I was installing windows I deleted my primary partition and an extended partition. I wanted to consolidate the space in a larger primary partition, but the installer would not consolidate the unused space, there were a multitude of unused space in each partition, I hit refresh, I have sailed on the installation and then headed in disk management again and still no dice. But it allows me to create a primary partition, but not a different scope, so I figure wrong install and try again, but within windows, still no dice. The only option available for this space is 'create new simple volume', I can walk through and get ready to create, but when I hit ok on the last window I get an error "There is not enough free space on the disk to complete this operation" if I put it to the maximum or minimum size, I get the same error.

    Is it possible to go back on my partition? or I'll have to scrounge something like partition magic and forget trying to do with windows?

    Hi Devarian,

    Thanks for the replies.

    When you want to extend a partition, for example the primary partition that you have installed on Windows 7, you should right click on the partition and select EXTEND the VOLUME.  Windows look for free space and give you a reading of how much free space is available to extend the volume of.

    Are you right click on the main partition or free space?

    Thank you

    The ones I found are valid. How to fix the object?

    Any help? Thank you.

    You must check the packaging STANDARD is valid and owned by SYS. Do the
    Next:

    (1) check the status of the STANDARD package using:

    connect sys /.
    SQL > SELECT * FROM DBA_OBJECTS WHERE OWNER = 'SYS '.
    AND OBJECT_NAME = 'STANDARD ';

    If you find the status is "DISABLED" then:

    SQL > ALTER THE STANDARD PACKAGE COMPILATION;

    You will find also a number of other packages 'is not valid.
    State. They must ALL be (re) compiled.

    If you find the STANDARD does not exist then:

    Check "$ORACLE_HOME/rdbms/admin/standard.sql" exists.

    If this file does not exist then:

    You probably have not installed PL/SQL.
    You must use the Setup program to install PL/SQL.

    If the file does not exist then:

    Make sure your ORACLE_SID is set correctly:

    SQL > connect sys /.
    SQL > @$ORACLE_HOME/rdbms/admin/catproc.sql

    (2) check that the STANDARD is owned by SYS:

    SQL > SELECT * FROM DBA_OBJECTS WHERE OBJECT_NAME = 'STANDARD ';

    If OWNER! = SYS then catproc.sql has not been executed correctly
    by SYS. You will have to drop these packets and re-run catproc
    as SYS.

    (3) try to run 'catalog.sql' and 'catproc.sql' at the opening of a spool file
    to intercept errors that may have occurred.

    Look for errors such as:

    ORA-00604: an error has occurred at the SQL level 1 recursive
    ORA-04031: unable to allocate 2 192 bytes of memory ("pool shared, shared

    (', ' PROCEDURE$ ', 'KQLS bunch', 'BLOCK the MEM KQLS')

    Create or Replace:
    *
    ORA-06553: PLS-213: STANDARD package is not accessible
    Grant execute on STANDARD to the public

    ORA-04042: procedure, function, package, or package body does not exist

    In this case, you need to increase the 'SHARED_POOL_SIZE' in the
    "init .ora.

    Then run back CATALOGUE and CATPROC.

    Increase "SHARED_POOL_SIZE" will allocate more resources and
    allow scripts to run successfully.

    Explanation:
    ============

    The PL/SQL compiler could not find the STANDARD package in the current
    Oracle database. To compile a program, PL/SQL needs package STANDARD.

    I think that; This is useful to solve your problem.
