• I have windows vista on this computer and I want to remove it and add windows xp.

  I have Windows Vista on this computer and I want to remove it and replace it with Windows XP Professional.  Whenever I tried to do, I succumbed. I tried to just boot from the cd and install xp and it tells me that the version on the computer is newer than the one I am trying to install and then gives me no option besides. I left and I restarted in safe mode and the command propt tried to fdisk and he said no authorized for this.  When I try to format it is said that volume id and I don't know who.  I've never been so lost trying to remove a platform in my life.  I would like to have an answer to this problem, thanks and have a blessed day, Robin

  Hi Robin,

  ·         What is the type of disc you are having? It's a drive to upgrade or full version?

  ·         How many partitions are present on the computer?

  ·         Why would you downgrade from Windows Vista to Windows XP?

  You need demarrer start from the installation disc, choose the partition where Windows is installed (ideally the C drive). Format it and then go to the Windows XP installation.

• Grep to remove parentheses and add dash here

  Hi guys,.

  I have long paragraph Notes with parenthesis between the numbers.  Here is the sample photo

  

  How can I write a GREP command for

  (1) remove all parentheses in the list (as in the example number 1 in the text)

  (2) add a space after the number

  (3) add the Indent here at the beginning of the text.

  If it's too complicated just with the removal of the brackets would be great!

  Thanks for any help and best!

  S

  Your typical grep added a tab and a return. My grep has added to the tab.

  If you want to use the indent to here instead, try to use this to replace it:

  $2 ~ m ~ I

  This will give you the number, an m-space and character dash out.

• Remove duplicates and fix a join table

  Oracle 10.2 g
  
  I have two tables and a table of junction between them.
  
  Table_a
  name identity
  1 TEST
  2 OF TEST2
  TEST 3
  
  Table_B
  ID
  1
  2
  3
  4
  
  TableA_TO_B
  A_ID b_id
  5 5
  1 2
  3 3
  
  Duplicates could not in table A, but the unique constraint has been accidentally disabled.
  
  So I want to be able to do is to remove all duplicates of table A, and if there is no line in
  TableA_TO_B that contain identifiers should be deleted, I want to update this line to refer to the now single
  TableA line.
  
  I am able to find duplicates by practice
  
  Select the id of the table_a where rowid > (select min (rowid) in the b table_a where b.SID = b.name)
  
  But after that I'm stuck.

  Hello...

  There may be a more elegant way to do this, rather than create an intermediate table, but... (note that this is NOT tested and may need some tuning/indexing on the staging table if you operate on large data sets!) :

  (1) create a temporary table by storing the ID to keep (and thus the value updated in TableA_B) - Note This code assumes that the folder with the ID (MIN) low will be the value stored in TableA...

  create table tmp nologging as
  select id,name,min(id) over (partition by name) ID_TO_KEEP
  from table_a;
  

  (2) execute the update statement, by changing the values that must be maintained (i.e. no are NOT deduplicated):

  update tablea_b ab
  set a_id = (select id_to_keep from tmp where id=ab.id);
  

  (3) perform the delete duplicates deleting statement in TableA (NOTE: assumes that you do not have etc. funky foreign key constraints on tables!):

  delete from table_a a where EXISTS (select id from tmp where id=a.id and id<>id_to_keep);
  

  I hope that works for you...! ;-)

• How to identify and remove duplicates and files in Windows 7 and those who are not the files in Win 7

  I used a program called IntelliMover and think that it flies over the files and unnecessary files.  How can I identify and delete these files?

  If make sure you that the files are not used by some programs or windows, then, the answer is YES.
  Easier would be, just look for duplicates in the folders where the files are not required by Windows or programs.

• Access table in the arraycollection collection and add the item at the end of the table

  I have this code to try to access the values in the table in the arraycollection collection, but that's not it actually creates a value at the end of the arraycollection collection. can someone tell me what im doing wrong I basically want retransmits the individual tables in the arraycollection collection and add Login_user

  So, I guess your ArrayCollection collection holds an array of objects, as follows:

  public var myAC:ArrayCollection = new ArrayCollection([{first:"bob",last:"smith"},{first:"jim",last:"jones"},{first:"mary",last:"allen"}]);
  

  And you try to add a new property of login_user to each of them, right?

  for each (var obj:Object in myAC) {
       obj.login_user = obj.first + "83";
  }
  

  Each person would be firstly, properties last and login_user.  In my example above, all the login_user would set their name + number 83, so adjust you accordingly for your application.

  It is the ease (for each rock for this situation).  However, if you want to paste the iterative approach, you have published, you can try this:

  for (var i:int = 0; i < myAC.length; i++) {
       myAC.getItemAt(i).login_user = myAC.getItemAt(i).first + "83";
  }
  

  I think that the for each syntax is clearer, but anyway works the way I think you want.

• To check and remove duplicate records

  Hi guys,.

  I have a T1 table where my col_1, col_2, col_3 columns are primary keys and the table is to have a huge volume of data recorded about 200 billion. Before you add the primary key, I need to check if there are duplicates and then delete these records. Who will be fastest way to check, I used below

  Select * from T1

  where rowid in (select rn (INF. Select rowid,

  DENSE_RANK() on ln (score of col1, col2, col3 order by rowid)

  from T1)

  where ln <>1);

  Is there another way using the analytical function can be faster to access the records of 200 billion

  Sven wrote:

  Instead of making a deletion consider to re-create the table using only the unique values. Very often, it's much faster than a delete even if more data is moved, but as always, it depends.

  It would be useful if you know how many lines you have and how duplicates are for example (the number of records is removed).

  Also, you should have a comparable test database, which is not always easy to have with large datasizes are invloved.

  Yes, Sven is quite right, ETG might actually be faster to remove duplicates of the original. But you will need to investigate the volume of data.

  create table T2 as

  Select col1, col2, col3,..., coln - all original columns except rn

  from (select t.*, row_number() on rn (score of col1, col2, col3 order by rowid)

  t)

  where rn = 1

  /

  Then hover over any constraint, etc. and drop T with purge, rename T2 in T.

• 3.6.2 the numbers help find and remove duplicates in 2 columns

  Could someone help me please. I run a karaoke business. As you may have guessed I have books with many songs, 64 000 and more than 75% of these songs are duplicates so you can imagine by train to sort. Option 1 I could manually go through my list by removing duplicates or option 2 attempt to find a formula that works save me hours of blind deletion. Is there someone out there who can help? It would be much appreciated thanks.

  Here is a sample of the document I'm working.

  

  Hi robi.

  Here is a solution of Craig s. Ruddock in this discussion Re: duplicates warning formula

  

  Formula in B2 (fill down)

  = IF (COUNTIF($A,A) = 1",","duplicate")

  Now sort by column A

  

  Remove all but one of the "duplicate" lines for each song.

  Kind regards

  Ian.

• What is"safe" to remove in my add and remove programs?

  What is 'safe' to remove in my add and remove programs?

  As the "Show updates" box is NOT checked, pretty much everything shown in Add / Remove programs other than "Windows Service Pack 3" is safe to delete.

  If you'll be glad later is another story.

  If you don't know what a given application, you can either Google it or ask here and someone will probably be able to tell you what it is and if it is likely that any other thing depends on the application.  For example, it is 'safe' remove the different versions of Microsoft .NET Framework, but this would almost certainly result in another application no longer able to function.
