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
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 COMPONENT_XSL_ID                          NOT NULL NUMBER(18)
 LINE_OF_BUSINESS                          NOT NULL VARCHAR2(30)
 ORDER_SOURCE                              NOT NULL VARCHAR2(10)
 COMPONENT_NAME                            NOT NULL VARCHAR2(30)
 COMPONENT_SCHEMA_VERSION                  NOT NULL NUMBER(9)
 ACCESS_LEVEL                              NOT NULL VARCHAR2(30)
 COMPONENT_XSL                             NOT NULL SYS.XMLTYPE STORAGE BINARY
 DESCRIPTION                               NOT NULL VARCHAR2(200)
 HASH_VAL                                           NUMBER

HASH_VAL is the newly added column.

Thank you

Mani

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 ());

    I have not tried running your code, but here are some possible solutions:

    1. There is a primitive to write the value of a control by index (added in ~ 2013). This is designed to be used others live too and should work like a local.
    2. You can send data using another way (like a queue, etc.).
    3. Use the Ctl Val.Set method.
    4. Do not use a chart. Use a chart and manage the buffer yourself. You can find some examples if you're looking for graph XY.

  • 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.

  • Documentation about adding column with the DEFAULT value.

    Hello

    http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_3001.htm#i2198241

    < quote >
    If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.
    < quote >

    I am not able to understand the emphasis on the part AFTER UPDATE while the column with DEFAULT values addition triggers both BEFORE and AFTER triggers defined on UPDATE.

    According to the documents of 11 g

    http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3001.htm#i2133105

    n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.

    This insistence is intended? If not, IMO, it should be changed.

    Kind regards

    Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

    When you add a column, the initial value of each row in the new column is null.

    * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

    This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

    * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

    Hope that helps to clarify the matter further.

    Kind regards

  • Plan of the hash value for two queries!

    Hello
    DB: Oracle 11g (11.2.0.3.0)
    OS: RHEL 5

    I have two question:

    1. can two queries have the same hash value of the plan? I mean I have here are two queries:

    SELECT /+ NO_MERGE * / MIN (payor.next_review_date). *
    * Payer from *.
    * WHERE payor.review_complete = 0 *.
    * AND payor.closing_date IS NULL *.
    * AND payor.patient_key = 10; *

    and

    SELECT MIN (payor.next_review_date)
    * Payer from *.
    * WHERE payor.review_complete = 0 *.
    * AND payor.closing_date IS NULL *.
    * AND payor.patient_key = 10; *

    When I tried to examine the execution plan for the two motions, the hash value of the plan remains the same. This means that implementation plan for both queries are same? If so, then how Oracle includes or changes to the execution plan based on hint. If not, then what hash value of the plan represents?

    2. If the plan with suspicion, and without suspicion is identical except for a given query except the number of lines and bytes. Do you mean this query with fewer lines and scanned bytes is better?

    Yes - as already said - but it's not just because of tips.

    Here is the example code that I use to show that Oracle does NOT simply use a text version of the query that you propose and compute a hash of it.
    These two queries are radically different but have the same hash value; Oracle are not different at all.

  • Creating a trigger to insert delete update with the sequence number

    Hey all,.
    I have two tables. tbl_main, tbl_temp. Whenever a record is inserted, deleted, updated in tbl_main, I need to insert the records in tbl_temp. All field/column names are exactly the same, except that in tbl_temp, I now have a single column by using a sequence number, a column to determine if the record has been updated, remove, modified(hence the codes) and the date when a record has been added to the table.
    So far, that's what I have:

    create or replace
    audit_trg relaxation
    after update or insert or delete ON tbl_main
    for each line
    Start
    If the update can
    insert into tbl_temp (seq_id, idx, ctl, action_taken, date_added)
    VALUES
    (temp_seq.nextval, idx, mke, ctl, sysdate, 'U');
    ELSif INSERTION then
    insert into tbl_temp (seq_id, idx, ctl, action_taken, date_added)
    VALUES (temp_seq.nextval, idx, mke, ctl, 'n', sysdate);
    ELSIF deletion then
    insert into tbl_temp (seq_id, idx, ctl, action_taken, date_added)
    VALUES (temp_seq.nextval, idx, mke, ctl, would be ', sysdate);
    END IF;
    END audit_trg;

    I tried several combinations, but I get many compilation errors. This code looks good or I am the way of track? Thanks in advance.

    Who looks fine for me. What are the mistakes are you?

    Assuming that MKE and CTL are columns in the base table, your INSERT statements will insert either the: new.mke and: new.ctl values or the: old.mke and: old.ctl values in the table. Presumably, you could insert the: new values for inserts and updates, and the: old values for deletions.

    Restrictions does not after ISO put 10.0.1 update with the new iPhone 7 any which option of ranking app I don't choose no changes are made.  All the patches?

    Thank you

    Hello Launcher,

    Thank you for bringing your question about Restrictions here in Apple Support communities. My understanding of your question is that you change the Restrictions, but no change is noticed. I tried the same on my iPhone 6 Plus running iOS 10 and noticed a similar situation. Please allow me the opportunity to explain how the Restrictions is designed to work. First, I put my limitations for applications, do not allow Apps and together 4 +, which basically means everything beyond 4 + will be blocked from buying. Then I went to the App Store and the first app that caught my attention was NCIS: hidden crimes. This app is rated 12 + and is definitely an application I would not want my toddler to help. It is that Restrictions come into play. When I type on NCIS: hidden Crimes, the Get option is grayed out. Restrictions does remove all apps, songs, books, etc. from view, but it will prevent the purchase, download, and install all applications rated above the setting you choose when you set up restrictions. It's the help article that discusses the Restrictions and prevent purchases: Use Restrictions in order to avoid buying on iPhone, iPad, or iPod touch.

    I checked on the restrictions help articles, and I understand where it can be a bit confusing. In the help article Use Restrictions on iPhone, iPad and iPod touch, it says "You can use Restrictions, also known as parental control, to block or limit specific applications and features on your iPhone, iPad or iPod touch." This means in fact that apps, features or services (rated above that helped you, or if you have turned off completely) can he no longer appears on the device if the restriction is activated and starts blocking them. I also tested this by activating Restrictions and turned the cursor for Safari to off. When I went back to the home screen, Safari doesn't show any more and I could no longer use it.

    I hope this helps to clarify how the Restrictions. If my understanding of the issue was not accurate to the issue that you are experiencing, I will be happy to pursue this issue with you. Please indicate exactly what you took measures, and what expectations you had or the some restrictions, applications, features, or services you are restricted. Thanks again and have a great rest of your day!
