• Update a primary key of type char data

  Hello
  Not a guy to oracle technology. but am forced to work on a query that is a basic requirement.
  
  I have a table that has a composite primary key values (6 columns).
  Of these, I've updated 1 specific column, which is a char data type.
  
  I tested after writing my logic as a query, threw it [the Unique constraint violated schema.tablename];
  
  So I gave it a query simple base to test it yet, still get the same error.
  
  Query such as:
  
  Update table_name set Column1 = "100000" where column2 = 'BOMBAY '; (Column1 is the primary key of type char)
  
  Even if it did not work.
  Now a doubt arises, a column is a primary key of type Char can be modified? or is it not possible at all to do?
  
  Note: I made sure only am not updated with a duplicate value;
  
  
  Thank you.

  While you never need to update a primary key (regardless of the type of data), it is possible to do. If you get an error ORA-00001 indicating that a unique constraint has been violated and the unique constraint that is violated is associated with the primary key of the table (I'm guessing that this is the case according to your description of the error), implying strongly that the update would result in duplicate rows. Your UPDATE statement updates more than 1 row? If so, how do you determine when the update is complete there will be no duplicate lines?

• update other items with the same value when when the column contains Y

   
  CREATE TABLE TEST 
     (     "QUATINTY" NUMBER(17,2), 
       "AMOUNT" NUMBER(17,2), 
       "ERRORRED" VARCHAR2(16 BYTE), 
       "PO" VARCHAR2(12 BYTE), 
       "LINE" VARCHAR2(10 BYTE), 
       "SEQ" VARCHAR2(14 BYTE), 
       "INVOICE" VARCHAR2(16 BYTE)
     ) 
  
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('123',5,50,'Y','1','1','inv1');
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('123',5,50,null,'1','2','inv1');
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('125',5,50,null,'1','1','inv2');
  Insert into TEST (PO,QUATINTY,AMOUNT,ERRORRED,LINE,SEQ,INVOICE) values ('125',4,50,null,'1','2','inv2');

  If you notice the table above which im trying to Edifier is updated the errorred column with 'Y' if the po and invoice are the same and have a 'Y' on the wrong column.
  in other words, I should finish with "Y" in the column for INV1 errorred.
  Can someone point me in the right direction, I can't for the life of me figuered it out.

  Hello

  Here's one way:

  UPDATE     test
  SET     errorred     = 'Y'
  WHERE     NVL (errorred, 'N') != 'Y'
  AND     (po, invoice)          IN (
                            SELECT  po, invoice
                       FROM      test
                       WHERE      errorred  = 'Y'
                             )
  ;
  

  This requires that the po and invoice are not NULL. If a column can be NULL, then the solution might be a little messier, according to the results you want, but only a little. Post some sample data (with null values) which shows what types of situations, you need manage, and the results of the SAMPLES.

• How to update columns with the value of other lines in the same table

  Hello
  
  I use Oracle 11.2, I'd use SQL statements to update a column based on values in other rows in the same table. Here are the details:
  
  create table TB_test (number 4 myId, crtTs date, date of MDPU);
  
  insert into tb_test (1, to_date ('20110101', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110201', 'YYYYMMDD'), null);
  insert into tb_test (1, to_date ('20110301', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110901', 'YYYYMMDD'), null);
  insert into tb_test (2, to_date ('20110902', 'YYYYMMDD'), null);
  
  After you run the SQL code, I would like to have the following result:
  
  1, 20110101, 20110201
  1, 20110201, 20110301
  1, 20110301, null
  2, 20110901, 20110902
  2, 20110902, null
  
  Thanks for your suggestion.

  I guess you need this, otherwise please explain logic correctly:

  SQL> merge into tb_test t
    2  using (
    3    select rowid as rid
    4         , lead(crtts) over(partition by myid order by crtts) as updts
    5    from tb_test
    6  ) v
    7  on (t.rowid = v.rid)
    8  when matched then update
    9   set t.updts = v.updts
   10  ;
  
  5 rows merged.

• update to column values (false) in a copy of the same table with the correct values

  Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.
  
  My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:
  
  
  Update mnt.workorders
  Set approvalstat = (select b.approvalstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  where exists (select *)
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  
  It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.
  
  Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:
  
  Update (select a.comappstat, b.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi - this is a PK column
  and a.comappstat! = b.comappstat)
  Set b.comappstat = a.comappstat
  
  Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:
  
  Update mnt.workorders_copy
  Set comappstat = (select distinct)
  a.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi
  and a.comappstat! = b.comappstat)
  where a.comappstat! = b.comappstat
  and a.workordersoi = b.workordersoi
  
  The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :
  
  ERROR on line 8:
  ORA-00904: "B". "" WORKORDERSOI ": invalid identifier
  
  First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)
  
  Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?
  
  I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.
  
  Thank you

  Hello

  First of all, after post 79, you need to know how to format your code.

  Your last request reads as follows:

  UPDATE
    mnt.workorders_copy
  SET
    comappstat =
    (
      SELECT DISTINCT
        a.comappstat
      FROM
        mnt.workorders a
      , mnt.workorders_copy b
      WHERE
        a.workordersoi    = b.workordersoi
        AND a.comappstat != b.comappstat
    )
  WHERE
    a.comappstat      != b.comappstat
    AND a.workordersoi = b.workordersoi
  

  This will not work for several reasons:
  The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
  There is no link between the mnt.workorders_copy and the the update and the request of void.

  If you do this you should have something like this:

  UPDATE
    mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
  SET
    A.comappstat =
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  WHERE
    EXISTS
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  

  Speed is not so good that you run the query to sub for each row in mnt.workorders
  Note it is condition in where. You need other wise, you will update the unchanged to null values.

  I wouold do it like this:

  UPDATE
    (
      SELECT
        A.workordersoi
        ,A.comappstat
        ,B.comappstat           comappstat_OLD
  
      FROM
        mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
        ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
  
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    ) C
  
  SET
    C.comappstat = comappstat_OLD
  ;
  

  This way you can test the subquery first and know exectly what will be updated.
  This was not a sub query that is executed for each line preformance should be better.

  Kind regards

  Please help IV ' e have no idea what to do about it
  Hi vickysumner,
   
  -Do you remember the number of Knowledge Base (KB) updates that are offered to install several times?
   
  -What is the corrupt file that you're talking about?
   
  -Do you have pop ups or any error message that a file was deleted? If Yes, specify exactly the error message verbatim.

• Conflicts of SQL columns on the same table

  I have a table with two columns used for the same purpose. Examples (start_date and career_history_start) (end_date or career_history_end).
  The columns have different (varchar2 and date) data types. The developer has used the data type date (start_date) to write the report and of the use of time even the vachar2 to manully insert date. We decided to use a single (varchar2). Meanwhile, there are differences in the two columns. We will find the difference between the two columns start_date (date) and career_history_start (varchar2).
  
  No idea what query will accomplish this considering they gave different type on the same table?
  
  Here is the description of the table:

  The customer doesn't care how the data is stored in the database. He care how it is displayed.

  What happens if your client has another office in a zone schedule differnet and each office needs display their time locally, but the server must store all the time in the same zone. How do they manage that when storing dates as a varchar data type. You get that kind of built-in functionality when you use a date data type

  In its simplest form if the customer is always display the data as a string, and then create a view from top of the table and convert dates in any format the customer prefers and that expose to the client.

  In this way, you get data stored properly and the client allows you to view data in the way they prefer

  Hi mdsavol,

  Your observations are accurate. The 'suggestions' are previous entries in the same column that correspond to what has been entered so far in the active cell. The only direct user control is to activate the function turn on or off in numbers preferences > general.

  There are other ways to include or exclude items of suggestions:

  • To remove typos in the suggestions list, the user must correct the typos in the cell above the active cell. If they are more in the list, they won't be presented as suggestions.
  • To include selections added to the list, the user must enter these suggestions in the individual cells above the active cell and column where they are wanted as suggestions.

  There was a request here a while there is a list of suggestion 'live' similar to those of some websites, which offers a descending list of possible entries as a type in an input box.

  The only way I see to reach a solution similar to what you have asked is to use as many lines at the top of the non-en-tete of the table section to list the items likely to repeat in your table, and then hide the lines. You'll need a list for each column where you want to use this feature with a list previously planted. Existing items will then require a likely hit up to three, then a click to choose from a list small enough to enter a value into a cell. News he will need to enter in full the first time, but after that it will be put on the list and answer the same thing as the terms preseeded.

  While your setting upward (or decide not to do), consider going on the menu of number (in numbers), choosing to provide feedback from numbers and writing a feature in Apple request. Describe what you want. Explain how he could help the average user numbers, and then hope for the best.

• In Istore during the application update comes first it puts up-to-date but that after a day he again comes that I store for release on the same date that I've already updated.

  I upgraded store shows erratic behavior

  I had something similar happens a few times a month. E same app kept saying he needed an update. Another symptom was that the icon was showing an update was available, but when I went to the screen updates, the install button changed to the button open before I had the chance to type.

  I have fixed by opening the app, double tapping the home button, hit to swipe the application to the top of the screen and then perform a hard reboot.

  Hi jjackbcop,

  Thanks for posting in the Microsoft Community.

  I understand that you are facing the issue with windows updates offer several times over and over again.

  Method 1:

  I suggest you perform the clean boot and check.

  Place the computer in a clean boot state, then check if it helps. You can start Windows by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  How to configure Windows XP to start in a "clean boot" State

  http://support.Microsoft.com/kb/310353

  Note: After completing the steps in the clean boot troubleshooting, follow these steps to configure Windows to use a Normal startup of the link report section to return the computer to a Normal startup mode.

• For the last month or more, I had the same two updates for my computer

  original title: Windows updates

  For the last month or more, I had the same two updates on my computer.  Is anyone know why and what I can do to fix this?  I am running Windows XP.  Thank you very much.

  Hello

  the message "you have hidden the important updates" is normal, because you have hidden the high priority updates, but the updates are already installed, if that's OK.

  Try to look again at the web page:

  http://www.update.Microsoft.com/

  and click on "Custom".

  You should not see the updates (KB2518864 and KB2539631) in "review and install updates.

  You should see only "Important - you have hidden the important updates..." and "high-priority - updates non-priority updates to update for your computer... ».

  Then, try this (remove the content of the "'C:\Windows\SoftwareDistribution" ")

  1. Click Start, click run, type services.mscand click OK.
  2. In the Services (Local) pane, click automatic updates, and then click stop.
  3. Reduce the Services (local) window.
  4. Select all the contents of the Windows distribution folder, and then delete them.

     Note By default, the Windows distribution folder is located in the drive: \Windows\SoftwareDistribution folder. This place is a placeholder for the drive where Windows is installed.

  5. Ensure that Windows distribution folder is emptyand enlarge the Services (local) window.
  6. In the Services (Local) pane, click automatic updates, and then click Start.
  7. Restart the computer.

  I hope that we will achieve the goal, it will no longer still report the updates :-)
