• Updated with the hash values column

  Hi all

  I have a requirement to add a column to a table and fill it with the hash values. The table contains an xml column and hash value of this column need to be filled to newly added column. I think that the ora_hash function will not support the xml type column. Just tested with the following script and it works.

  update TBL_COMPONENT_XSL set hash_val = ora_hash((SELECT TCX.COMPONENT_XSL.getStringVal() FROM TBL_COMPONENT_XSL TCX where rownum =1));
  

  can you please suggest me how to fill the column with the hash values.

  SQL> desc TBL_COMPONENT_XSL

  HASH_VAL is the newly added column.

  What happens if you try with:

  update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getStringVal ());

  update of TCX TBL_COMPONENT_XSL set hash_val = ora_hash (TCX.COMPONENT_XSL.getClobVal ());

• 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

• Software AIO with the only USB 3.0 systems problems

  I just had problems with the installation of PSC 1510 and J5780 to be connected systems USB 3.0 only as a Fujitsu Lifebook A544 under W7 - 64.

  In both cases, download the latest package and stopped installation:

  http://www.Club-PAC.de/download/HPj5780-error.PDF%C2%A0

  W7-64 systems are fully patched, a "naked" before first Installation HP look so no HP software - lay before.

  Solution (at least for Fujitsu of A544):

  If possible, use BIOS routines disable the functionality of USB 3.0 and USB 2.0 only instead.

  Windows will then take some time to install drivers for USB for USB 2.0 devices, but after that, the HP AIO software installation will succeed.

  Now, you can reactivate the USB 3.0 feature in the BIOS. Believe it or not, software, printer, scanner still doesn't work.

• Import csv into Apex with the only time data.

  Hello

  I tried to understand this question for awhile now and have been on several forums without success.

  IM learning SQL and PL/SQL, so please be gentle

  I am in charge of a csv file, where the data is time in the "KO_TIME" column for example 13:30 'or 18:00 ' 24 hours just hours and minutes.

  I am aware of the TO_CHAR function to convert a date to a string in an insert statement, but I want to be part of the creation of the table syntax, so I'm able to use the Import CSV APEX tool and it will include the time format data 00:00.

  The creation of the table is so far, but with syntax errors;

  CREATE TABLE  "FOOT_BALL_VENUES" 
     (     "ID" NUMBER, 
       "DESCRIPTION" VARCHAR2(30), 
       "DAY" VARCHAR2(30), 
       "DATE_FIX" DATE, 
       "KO_TIME" DATE AS (TO_CHAR('HH24:MM') 
                  "FIXTURE" VARCHAR2(255), 
       CONSTRAINT "FOOT_BALL_VENUES_PK" PRIMARY KEY ("ID") ENABLE
     )
  /
  
  CREATE OR REPLACE TRIGGER  "bi_FOOT_BALL_VENUES" 
    before insert on "
   
  FOOT_BALL_VENUES"        
    for each row 
  begin  
    if :new."ID" is null then
      select "FOOT_BALL_VENUES_SEQ".nextval into :new."ID" from dual;
    end if;
  end;
   
  /
  ALTER TRIGGER  "bi_FOOT_BALL_VENUES" ENABLE

  Thanks for your time guys.

  Hello

  If your KO_TIME csv column have alone time, then use the data type VARCHAR2 to your column of table KO_TIME.

  If KO_TIME csv column have the date and time, and then use the DATE format and for example create the virtual column that shows the only time.

  CREATE TABLE  "FOOT_BALL_VENUES"
     (     "ID" NUMBER,
       "DESCRIPTION" VARCHAR2(30),
       "DAY" VARCHAR2(30),
       "DATE_FIX" DATE,
       "KO_TIME" DATE,
       "KO_ONLY_TIME" VARCHAR2(255) GENERATED ALWAYS AS (TRIM(TO_CHAR(KO_TIME,'HH24:MI'))) VIRTUAL,
       "FIXTURE" VARCHAR2(255),
       CONSTRAINT "FOOT_BALL_VENUES_PK" PRIMARY KEY ("ID") ENABLE
     )

• Book the question of transfer with the only difference being: point Info/display: any device OR any stand-alone devi

  I use ADE to transfer a PC (windows 7) in a corner. I had no problem until a recent book purchase. I can't transfer the book in the corner [title of the book CE_COPY_NOT_ALLOWED - without permission to copy the Book]. I did all the permission things that are always recommended [allow the PC, remove and allow the PC, remove records of Nook, reauthorize Nook, etc.] several times. The Nook fine copy all the old books. But this will not be [I even bought another to check and it is not]. I have 2 books (a copy and we won't) from the same Editor (I bought a few months ago and the other is a new). The only difference I see is that when you select the book, click right, look at the Info under viewing point there are 2 different things. For the book which will copy, an observation: on any device. [For the book that doesn't copy, an observation: on any stand-alone device]. There seems to be a change DRM. What can I do?

  Thanks-*-Roy

  I've not seen the ' display: on any stand-alone device "before.

  One thing to try is to evade the ADE and a copy to the .epub DRM from PC to Nook by using Windows Explorer or similar.

  The info book by ADE will tell you where the file is on the PC.

  Probably should go in the "Digital Editions" folder on the corner, but should be pretty easy to see where the .epub files go. (***)

  Copy almost certainly works independently of the ' watch one: on any stand-alone device ' detail.

  It may or may not be that the meal will be ready to show it once it's there.

  (*) p.s. just realized that you can find where the books are placed on the corner of info book by ADE as well.

  Just look at your Nook library in ADE and watch the news.

  At least, it will work for books in the corner; then say you the right directory.

• column with the only format of loading time

  My DB, 11 2 on OEL 5.5 GR
  Hi all
  I have a problem with the loading of the external table. I have a txt file with a format of columns HH24:MI:SS

  START_TIME
  00:10:20
  01:15:11
  02:11:10

  And I don't know which data type use in external table because in the future, I'll have to do some calculations on this column, so I should load as a DATE, but miss me "mm/dd/yy" to the front. Any suggestion how to do properly?

  You could use a data type CHAR or date for the outer table and do your math with this column correctly.

  The key is that convert a time string to a date data type will add the current date to it. For example:

  SQL> alter session set nls_date_format='dd/mm/yyyy hh24:mi:ss';
  
  Session altered.
  
  SQL> select to_date('00:10:20', 'hh24:mi:ss') from dual;
  
  TO_DATE('00:10:20',
  -------------------
  01/02/2011 00:10:20
  

  Some examples of code for both cases, by using the DATE and CHAR data type. I tested it on 11.2.0.1:

  CREATE OR REPLACE DIRECTORY ext_tab_dir AS '/tmp';
  
  -- /tmp/info.txt
  1,00:10:20
  2,01:15:11
  3,02:11:10
  
  alter session set nls_date_format='dd/mm/yyyy hh24:mi:ss';
  

  (1) using the DATE data type

  drop table tab_time_date;
  
  CREATE TABLE tab_time_date (
    key VARCHAR2(5),
    start_time date)
    ORGANIZATION EXTERNAL (
       TYPE ORACLE_LOADER

        (FIELDS TERMINATED BY ','
         (key char(5),
          start_time CHAR(8) DATE_FORMAT DATE MASK "HH24:MI:SS"
         )
        )
        LOCATION ('info.txt'));
  
  select * from tab_time_date;
  
  KEY   START_TIME

• Several lines in duplicate with the null value displayed in the combined analysis rpt

  Dear all,
  
  Our requirement is to display users open tasks (my open tasks) on the home page. So I created a report called open my tasks.
  
  The columns to display are subject, account name, due date, owner. If I use only the 'activities' notification area, and then I can not retrieve tasks that have NULL of the account name. SOD ignore and filter the tasks with the NULL account name if I display the name of the account.
  
  So I used a combined analysis of activity report activity with itself i.e. area statement. All columns except account name in one of them where I used "instead of the name of Account.Account.
  
  It now also displays tasks with NULL account name. But there is another question. These activities when there is an account name, display double - double rows - an account name and othet without account name (for example, NULL).
  
  Please can you help how to solve above or meet the requirement in an alternative way?
