Doubt about the update/insertion of a Table

I have a long SQL insertion. While SQL is running, update one or more tables sources. What data will be inserted by the SQL in the target table, updated or before update?

Hello

I said regarding how widespread, this market not in what concerns the selection.

  • doubt about the update

    Hi all

    Three statements to update, I need to run on a single table.
    Is there a way I can update instructions executed all three in a single statement?
        UPDATE xxops_forecast_extract b SET territory_id = (SELECT a.territory_id
         FROM fdev_hier_node_mv a
         WHERE a.shr_node_id = b.shr_node_id
          AND NVL(end_dt,SYSDATE) > SYSDATE) ;
    COMMIT;

    UPDATE xxops_forecast_extract b SET position_id = (SELECT a.row_id
        FROM s_postn a
        WHERE a.name = 'TD-'||UPPER(b.am_id))
        WHERE position_level = 7
        AND b.am_id IS NOT NULL;
    COMMIT;
  
    UPDATE xxops_forecast_extract b SET position_id = (SELECT a.row_id
        FROM s_postn a
        WHERE UPPER(a.desc_text) = UPPER(TRIM(B.POSITION_NAME)))
        WHERE position_level = 7
        AND b.am_id IS NULL;
     Below are the sample data for the tables. 

 xxops_forecast_extract

    Hello

    You can combine the statements by combining subqueries.
    No logic not apply to all the the original updates must be out of the WHERE clause and put in a CASE statement.
    The CASE statements should "update" column to itself if none of the conditions apply.

    For example, your final two statements UPDATE, that have subqueries on s_postn, both can be combined like this:

    UPDATE     xxops_forecast_extract     b
SET     position_id =
     (
     SELECT     CASE
               WHEN     (     b.am_id          IS NOT NULL
                    AND     UPPER (a.name)     = 'TD-' || UPPER (b.am_id)
                    )
               OR     (     b.am_id          IS NULL
                    AND     UPPER (a.desc_text)     = UPPER (TRIM (b.position_name))
                    )
               THEN     a.row_id
               ELSE     b.position_id
          END
     FROM     s_postn     a
        WHERE     UPPER (a.name)          = 'TD-' || UPPER (b.am_id)
     OR     UPPER (a.desc_text)     = UPPER (TRIM (b.position_name))
     )
;

    There seems to be some mistakes in the statemnts UPDATE that you posted. For example, the last two refer to a column called position_level that does not exist in the other table.
    The above statement produces the results you want with the data you've posted.

    As you can see, the code is much harder to understand, debug and maintain.
    If the performance gain (if any) justifies the addional complexity is debatable in this case.
    I'm sure that combining all three queries would be useful.

    Consider using the MERGE: it is sometimes easier to use, even if, as in this case, you're never insert.

  • Doubt about the passage collection (Pl/SQL table) in a procedure.

    Hi all

    I have developed a package of sample with procedure 1. Here, I spent the output to a table in the collection data and I am passing the array of the collection as a parameter out.
    When I run the proc, it worked for 1 scenario, but did not work for the other. I posted two scenarios after the code.
    pkg spec:

create or replace
PACKAGE IMP_EXP_BKUP_PKG
AS
  TYPE test10_tbl2 IS TABLE OF test10.t1%type INDEX BY BINARY_INTEGER;
  v2_test10 test10_tbl2;
  PROCEDURE manpower_list(v1 number, v2 out test10_tbl2);
END IMP_EXP_BKUP_PKG;

Pkg Body:

create or replace
PACKAGE BODY IMP_EXP_BKUP_PKG 
AS 
PROCEDURE manpower_list(v1 number, v2 out test10_tbl2)  AS
BEGIN
  SELECT t1 BULK COLLECT INTO v2 FROM test10 WHERE t4 = v1; 
END;
END IMP_EXP_BKUP_PKG;
    Scenario 1:
    DECLARE
  v2 imp_exp_bkup_pkg.test10_tbl2;
BEGIN
  imp_exp_bkup_pkg.manpower_list('10', v2);
  FOR i IN v2.FIRST..v2.LAST
  LOOP
    DBMS_OUTPUT.PUT_LINE(v2(i));
  END LOOP;
END;
    Worked well.

    Scenario 2:
    DECLARE
  --v2 imp_exp_bkup_pkg.test10_tbl2;
  TYPE typ_tbl2 IS TABLE OF test10.t1%type INDEX BY BINARY_INTEGER;
  v2 typ_tbl2;
BEGIN
  imp_exp_bkup_pkg.manpower_list('10', v2);
  FOR i IN v2.FIRST..v2.LAST
  LOOP
    DBMS_OUTPUT.PUT_LINE(v2(i));
  END LOOP;
END;

Error:

    Is not here.

    I want to just make sure that, are we supposed to use the same type that we have breeding stock in the package for the declaration of the variables?

    Yes, you MUST use the same type definition.

  • Ask about the creation and filling I$ table on different condition

    Hello
    I have a question about the creation and filling I$ table on a different condition. In which condition the I$ table creation? And these conditions are given below:

    (1) * source and transit area * are on the same server (that is to say target is located on another server)
    (2) * gathering and target area * are on the same server (IE source is on another server)
    (3) * source, transit area and target * are * different 3 * Server
    Source 4), area transit and target are on the same server
    Thank you

    I'm not quite clear to your question. Always try my best to erase it.

    In your all over requirement I$ table will be created.
    If the same staging as target (a database, a user) then all temporary tables are created in this user
    If the scaffolding is different from the target (a database, two users (A, B)), then all temporary tables will be created under that user A (lets consider) and the data will be inserted into the target table that is present to user B

    Staging is different from the target (two database, two users (A1, A2), architecture not recommended) if all temporary tables will be created under that user A1 (A1 of the databases) and the data will be inserted into the target table which is present in user A2 (A2 data base)

    If the source, staging, the target will be under a database then no. LKM is required, IKM is sufficient to load the data into the target. Especially for this, you can see an example given by Craig.

  • Need help writing an update / insert with linked tables

    I'm close on this? This throws any errors, but it is not no longer works. It is so obviously wrong. I get a cfdump the end of my query of compairison, but once it hits the stated case, it is lost.

  • HP Pavilion dv4-1120br: doubts about the BIOS update for my model with the operating system current instaled.

    Hello

    I have a HP Pavilion dv4-1120br, I know that this model of HP laptop is old, but I instaled the 64 bit of Windows 10 on my machine and saw that my BIOS is version F.30 and the last of them available on the site of HP F.66 has.

    The problem is that this model is not suport for Windows 10 because, as I said, is too old. Can I download and run the update of the BIOS for Windows 7 64-bit available in the Web site, or I need to downgrade my OS to Windows 7, update the BIOS and then pass it back to Windows 10?

    Thanks for the help!

    Cantarino

    Hello;

    Let me welcome you on the HP forums!

    Your second proposal is correct - as the updates to the BIOS on the HP site are specific to the OS version and if you try to run one for Win7 in Win10, it will refuse to run.

    Good luck

  • How to temporarily disable the update insert dates?

    Hello!

    DW CC on MacOS 10.11.3 2015.1

    I use "Insert date" (see: https://helpx.adobe.com/dreamweaver/using/insert-dates.html) to track the most-recent-update of content pages.  The time stamp is displayed after "Page updated:"about content. "

    I just discovered a systematic error in repeated, without reusable content in 1500 + pages. Oh!

    The solution is simple and I would like to use search and replace in DW to do the job, but I want to leave all the most recent timestamps in these pages intact, that this correction does not affect content.

    My question: how to temporarily disable the DW mechanism that updates the timestamp in the markup?

    I suspect that there is a visible JS file that implements the update, and the path to success is to temporarily replace an inert version of the same name, but before you start digging for this...

    TIA

    The file you need to disable temporarily is at the following location in Windows: C:\Program Files\Adobe\Adobe Dreamweaver CC 2015\configuration\Translators\Date.htm. He will be in a situation similar to Mac OS X in the Applications folder.

    If you use an earlier version of Dreamweaver on a PC running 64-bit Windows, see C:\Program Files (x 86).

    Date.htm contains two JavaScript functions: getTranslatorInfo() and translateMarkup() you need to temporarily replace with dummy functions.

    Know that you will be editing a program file. Needs administrator privileges to do this. As long as you know what you're doing, it should not cause problems, but you do at your own risk.

  • Doubt about the Performance

    Dear all,
    I'm running a procedure, and it should update the 8 million records.
    It uses a packaged procedure which is going on in another data base using the link of database to get certain values based on certain parameters.
    If the procedure doesn't return any data (in THE settings) then it must be inserted into a table of newspaper.
    If the procedure returns some data then it must be applied to the record in the database, like that it must update all records of 8 million

    But my procedure takes more than 14 hours to run.

    The following procedure is that I'm getting.
    It seems very simple, but I really don't understand why she's taking a lot of time.

    Guess aside.
    1 > to fill the lack of recording in the JOURNAL Table I use a PRAGMA AUTONOUMOUS_TRANSACTION procedure in the procedure itself and commit the data to see the results of the PAPER while still it runs the procedure. This will cause this procedure got COMMIT inside.

    2 > or it's because we use an external DB which is present in another data base package.

    The procedure seems very simple, but I don't know why it takes a long time.

    Appreciate any feed back.

    Thanks and greetings

  • Firefox I want to find out about the updates only when the ons add that I installed currently become compatible. Is this possible?

    Firefox keeps advising me up-to-date even if a few Add ons are not compatible with the newer version. Although I don't want to be notified when an update is available, I won't update if the add ons are not compatible. Also, advising me update is useless because I will not refresh firefox when all add ons are not compatible.

    Is it possible to put the automatic notification about the availability of updates to appear only when all add ons are compatible?

    You can install this extension to see the information of current compatibility on the subject: addons page.

  • General question about the updates and version number

    I have a general question about versions and update.  I'm new on this and am in the deep end of learning I want.

    In vSphere web client, I see the following versions (these are exactly as the seller, he left a few months that I have screenshots in my documentation that match)

    Version - VMware ESXi, 5.1.0 1612806

    Profile - Dell (updated) ESXi - 5.1 - 799733 (A00)

    I am trying to familiarize themselves with the Update Manager and I noticed that there are a lot of patches and updates available.

    Lists of Update Manager 5 patches as "Missing" with Red x but directly above them are a list of patches with green tick indicating that "installed" - it is perhaps obvious, but im guessing 'installed' means really installed when displayed on the screen - there is an update installed, labeled "ESXI 5.1 all the update 2-' would be able to tell that it has been installed by the details of profile/version above?

    I don't think it's a big deal at this stage, but if I install all missing patches and then the details of the version/profile change in summary screen?

    I hope this makes sense.

    Thank you

    I am a member of creative cloud working with simple editing DPS. My app was approved by Apple and is in the store. But, of course, there is a typing error.

    Hi Chuck,

    Subscribe to Adobe Creative cloud can revise their applications (and submit their applications reconstructed at Apple) as long as they subscribe to creative cloud. When you change your application, use the same ID App and distribution provisioning profile to create the new custom Viewer. In DPS App Builder, select the existing application that you have created and click on modify. Specify the latest version of the app, if you want and follow the prompts to create a new app download and test the development agenda. In iTunes Connect, click on manage your Applications, click the application that you want to update, and then click Add Version. Follow the prompts and then use Application Loader to download the .zip file.

    Hello

    I've updated my bow to android 4.0.4 yesterday, and his great performance, I just want to ask when I updated it I did not remove my SIM and SD card, after updating all my contacts where always there and my installed is still installed, is this ok? I want to say that I expected that my installed applications will be

    P.S. the updated software was great, my phone is running smooth, thanks Sony,

    Yes, its normal, when the update using SUS you have two options here, update your phone without deleting your files or factory resetting your phone then install the update, or if you download the OTA update no file will be deleted. If you have problems you can reinstall the update or data factory reset your phone.
