• Are the files $NtUninstallKB83522WXP$ and lots of files with names like KB2566454.log is necessary to keep?

  Original title; These files are needed?

  I hundredes swith of file names such as $NtUninstallKB83522WXP$ and lots of files with names like KB2566454.log. Can they be deleted?

  My system became very slow lately and it's the first timeI saw these files.

  The files have dates between 2005 and 2012. My computer took more time to start and is much slower in response to requests.

  Because thses files take up so much space I would like if possible remove them.  I'm under Windopws XP SP3.

  If your PC behaves properly, you can remove the hotfix Windows backup hidden files that start with $NTUninstallKB to the WINDOWS folder. Be aware that once they are removed you will not be able to uninstall the updates they represent.

  There are two ways to do:

  1. manually, but copy the files on a CD/DVD first to enable their restoration has a fix must be removed at a later date. Now delete the folder \WINDOWS, but leaves the orphan entries to add / remove programs intact. Remove only the $NTUninstallKB files that relate to corrections, not those for applications such as Word, WMP, etc.. In addition, DO NOT DELETE THE folder$ $hf_mig.

  2. my preference is to run a script that also removes the corresponding entries in Add / Remove programs. Once they are deleted by the script, they cannot be restored. Download, extract and run this little script http://www.dougknox.com/xp/utils/xp_hotfix_backup.htm creating a system restore point first just in case something goes wrong when the update of the register.

• The system creates thousands of useless with names like temporary files ~ WRL2755.tmp, but they never disappear. How can I remove all at the same time?

  I am running XP Professional 2002 SP3. It all started about six months ago I suspect with one of these updates. These files are located in the files with the associated files. There are actually hundreds of thousands of them. They have tripled the number of files on my computer. I want to know how to get rid of them and stop the system from their creation.

  Hello Redoced,

  I found an article from knowledge explaining that ~ WRL .tmp files are created by Word, further than the WRL type .tmp files are created by Clipboard actions.

• BAD RESULTS WITH OUTER JOINS AND TABLES WITH A CHECK CONSTRAINT

  HII All,
  Could any such a me when we encounter this bug? Please help me with a simple example so that I can search for them in my PB.
  
  
  Bug:-8447623
  
  Bug / / Desc: BAD RESULTS WITH OUTER JOINS AND TABLES WITH a CHECK CONSTRAINT
  
  
  I ran the outer joins with check queries constraint 11G 11.1.0.7.0 and 10 g 2, but the result is the same. Need to know the scenario where I will face this bug of your experts and people who have already experienced this bug.
  
  
  Version: -.
  

  SQL> select * from v$version;
  
  BANNER
  --------------------------------------------------------------------------------
  Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
  PL/SQL Release 11.1.0.7.0 - Production
  CORE    11.1.0.7.0      Production
  TNS for Solaris: Version 11.1.0.7.0 - Production
  NLSRTL Version 11.1.0.7.0 - Production

  Why do you not use the description of the bug test case in Metalink (we obviously can't post it here because it would violate the copyright of Metalink)? Your test case is not a candidate for the elimination of the join, so he did not have the bug.

  Have you really read the description of the bug in Metalink rather than just looking at the title of the bug? The bug itself is quite clear that a query plan that involves the elimination of the join is a necessary condition. The title of bug nothing will never tell the whole story.

  If you try to work through a few tens of thousands of bugs in 11.1.0.7, of which many are not published, trying to determine whether your application would be affected by the bug? Wouldn't be order of magnitude easier to upgrade the application to 11.1.0.7 in a test environment and test the application to see what, if anything, breaks? Understand that the vast majority of the problems that people experience during an upgrade are not the result of bugs - they are the result of changes in behaviour documented as changes in query plans. And among those who encounter bugs, a relatively large fraction of the new variety. Even if you have completed the Herculean task of verifying each bug on your code base, which would not significantly easier upgrade. In addition, at the time wherever you actually performed this analysis, Oracle reportedly released 3 or 4 new versions.

  And at this stage would be unwise to consider an upgrade to 11.2?

• Customized using regexp check constraint

  Oracle 11.2.0.1

  I need a customized using regexp expressions check constraint.  We have a single column in our table REGNO, which is used to keep the registration number of our customers.  It has alpha and numeric values, the first is Alpha and rest is digital with preceding zeros as A0100 A1245, C1111 etc.  Sometimes, in the application user enters regnos evil if we want to stop entering the bad regnos i.e. assume that the user name is Ashok Kumar and in the series, we have 1000 users so this new user should have A1001 (other than any value A1001, in this example, the constraint must be limit to enter the value) only, not the others nor a1001 , A1000, nor A1002 or < has no > 1001 too. Rather than having 26 sequences (A to Z), we get a table where we have these columns:

  Alpha char (1), number of LastNo.  But sometimes a user enters wrong number value and stores it in the table, so next time for the same gap alpha arrives and confusing.

  So, we must have a constraint of database level so that ONLY the correct values must be entered.

  Kindly help me how I have this task please.

  Thank you.

  If REGNO is a derived value then why let you the user enter a value. Just generate the user.

  There are some workaround solutions...

  And to add, that your mistake here is different - you're talking about another column JDATE (typo..?) in the check constraint... The actual column name is ADATE... :)

• Date check constraint

  Please can I get some help with a check constraint.
  
  The Table is called the TITLE and the attribute is TI_RELDATE (a date). I am wanting to make sure that it is between 1930 and the date of the day.
  Is this something like this:
  
  CONSTRAINT TITLE_ck_TI_RELDATE CHECK (TI_RELDATE between 1930 and GETDATE())
  
  Canning

  GETDATE()-based you come from the side of SQL Server of the barrier. Literals in Oracle date are 'yyyy-mm-dd ". Now the part 'getdate '. What exactly are you trying to do? Make sure that the inserted/updated date to date is not a later date? If so, you need a trigger for this. Check constraint can do is make sure you inserted/updated date is 1930 or higher:

  alter table tbl
    add constraint tbl_chk1
      check(
            dt >= date '1930-01-01'
           )
  /
  

  Switch to make sure that the inserted/updated date to date is not a later date:

  create or replace
    trigger tbl_bir
      before insert
          or update
      of tbl
      for each row
      begin
          if dt > sysdate
            then
              raise_application_error(-20900,'Column dt value can't be a future date.');
          end if;
  end;
  /

• Get a NAMED check constraint when the entity attribute derived from the field

  I'm designing a new database and beginning with a logic model of the ER. I've defined several areas, such as the NO_YES field (with values of ' no and 'Y'). When I use this area as a data type of an attribute of the entity (for example, the CHANGE_REQUEST.IS_APPROVED attribute), I also specify a constraint name (for example, CR_APPROVED_CK) of the attribute (this is done in the Group of constraint, property name constraint and the properties of the attribute dialog box, default value).
  
  When I have the logic model to a relational model of the engineer, the constraint name is lost. Specifically, for the definition of the table that is created, for the column in question, in the default column properties and constraints Panel dialog box, the name of constraint property is empty. When I generated the DDL of the relational model, the check constraint that is generated is an inline check constraint (such as ' IS_APPROVED VARCHAR2 (1) CHECK (IS_APPROVED IN ('n', 'Y')) '). When this DDL is executed to generate database objects, the created check constraint has a system-generated name. I want the constraint to have a name that I create.
  
  By experimentation, I found that in the relational model, if I specify a value for the property name of the constraint in the DOF resulting constraint get named (an ALTER TABLE statement is generated that contains "ADD CONSTRAINT CR_APPROVED_CK CHECK (IS_APPROVED IN ('n', 'Y'))"). However, I have redundantly change the relational model in the same way that I edited the logic model to specify the constraint names.
  
  Is there a way to guarantee that the constraint names defined in a logic model transferred during the engineering of a logic model to a physical model.
  
  The version of the Data Modeler I use is 3.0.0.665.

  Is there a way to guarantee that the constraint names defined in a logic model transferred during the engineering of a logic model to a physical model.

  There is ' compare/copy options' tab in the technical dialogue - clear the checkbox "do not apply to new objects.

• CHECK constraint question

  Oracle 11 R2
  
  My question is if I can create a check constraint using a SELECT statement on a different table?
  
  So instead of
  
  CHECK (building ('01', ' 02', ' 03'));
  
  I can do something like this:
  
  CHECK (select distinct from the other table);
