• Oracle vs ANSI joins

  Note a 'strange' behavior when you use ANSI joins in Oracle and I was wondering if there are still problems with their use in Oracle (11 g)
  
  Basically I have a MV_F_PRODUCT_ACTUAL vision, which is defined as a self-join to work the point in time for a product like the following values:
  

  SELECT
    F_PRODUCT_PREV.i_SK_Product,
    F_PRODUCT_PREV.i_SK_Version,
    F_PRODUCT_PREV.i_SK_VersionDate,
    D_CALENDAR.i_SK_Date AS i_SK_PointInTimeDate,
    F_PRODUCT_PREV.i_SK_Current,
    SUM(F_BOOKING.f_NoPax) AS f_NoPax
  FROM
    F_PRODUCT F_PRODUCT_PREV
  LEFT JOIN
    F_PRODUCT F_PRODUCT_NEXT
    ON
      F_PRODUCT_NEXT.i_SK_Product=F_PRODUCT_PREV.i_SK_Product
      AND
      F_PRODUCT_NEXT.i_SK_Version=F_PRODUCT_PREV.i_SK_Version+1
  LEFT JOIN
    D_CALENDAR
    ON
      D_CALENDAR.i_SK_Date BETWEEN F_PRODUCT_PREV.i_SK_VersionDate AND COALESCE(F_PRODUCT_NEXT.i_SK_VersionDate-1,TO_NUMBER(TO_CHAR(TRUNC(SYSDATE),'YYYYMMDD')))
  LEFT JOIN
    (
      SELECT
        F_BOOKING.i_SK_Product,
        F_BOOKING.i_SK_Bkg,
        D_CALENDAR.i_SK_Date AS i_SK_VersionDate,
        MAX(F_BOOKING.i_SK_Version) AS i_SK_BookingVersion
      FROM
        D_CALENDAR
      INNER JOIN
        F_BOOKING
        ON
          F_BOOKING.i_SK_VersionDate<=D_CALENDAR.i_SK_Date
      GROUP BY
        F_BOOKING.i_SK_Product,
        F_BOOKING.i_SK_Bkg,
        D_CALENDAR.i_SK_Date
    ) F_BOOKING_ON_DATE
    ON
      F_BOOKING_ON_DATE.i_SK_Product=F_PRODUCT_PREV.i_SK_Product
      AND
      F_BOOKING_ON_DATE.i_SK_VersionDate=D_CALENDAR.i_SK_Date
  LEFT JOIN
    F_BOOKING
    ON
      F_BOOKING.i_SK_Bkg=F_BOOKING_ON_DATE.i_SK_Bkg
      AND
      F_BOOKING.i_SK_Version=F_BOOKING_ON_DATE.i_SK_BookingVersion

  i.e. use ANSI joined to solve on the beaches of different dates between our F_BOOKING and F_PRODUCT tables. I cut the code from there as much as possible while retaining the main features.
  
  Now, if I question this view with ANSI joins as follows:
  

  SELECT 
    D_PRODUCT.A_PRODUCTCODE,
    D_PRODUCT.A_PRODUCTNAME,
    D_PRODUCT.A_PRODUCTTYPE,
    sum(NVL(MV_F_PRODUCT_ACTUAL.F_NOPAX,0)),
    sum(F_PRODUCT.F_ACTIVEPAXRANGE)
  FROM 
    MV_F_PRODUCT_ACTUAL
  LEFT JOIN
    D_PRODUCT
    ON
      D_PRODUCT.i_SK_Product=MV_F_PRODUCT_ACTUAL.i_SK_Product
  LEFT JOIN
    D_CALENDAR
    ON
      D_CALENDAR.i_SK_Date=MV_F_PRODUCT_ACTUAL.i_SK_PointInTimeDate
  LEFT JOIN
    F_PRODUCT
    ON
      F_PRODUCT.i_SK_Product=MV_F_PRODUCT_ACTUAL.i_SK_Product
      AND
      F_PRODUCT.i_SK_Version=MV_F_PRODUCT_ACTUAL.i_SK_Version
  WHERE 
    D_CALENDAR.Calendar_Date='01/Apr/2010'
  GROUP BY
    D_PRODUCT.A_PRODUCTCODE,
    D_PRODUCT.A_PRODUCTNAME,
    D_PRODUCT.A_PRODUCTTYPE;

  Then, the query returns results in less than a second. However, our report default application using joins in Oracle style as follows:
  

  SELECT
    D_PRODUCT.A_PRODUCTCODE,
    D_PRODUCT.A_PRODUCTNAME,
    D_PRODUCT.A_PRODUCTTYPE,
    sum(NVL(MV_F_PRODUCT_ACTUAL.F_NOPAX,0)),
    sum(F_PRODUCT.F_ACTIVEPAXRANGE)
  FROM
    D_PRODUCT,
    MV_F_PRODUCT_ACTUAL,
    F_PRODUCT,
    D_CALENDAR
  WHERE
    (
      D_PRODUCT.i_SK_Product=MV_F_PRODUCT_ACTUAL.i_SK_Product  
    )
      AND
    (
      D_CALENDAR.i_SK_Date=MV_F_PRODUCT_ACTUAL.i_SK_PointInTimeDate
    )
      AND
    (
      F_PRODUCT.i_SK_Product=MV_F_PRODUCT_ACTUAL.i_SK_Product
      AND
      F_PRODUCT.i_SK_Version=MV_F_PRODUCT_ACTUAL.i_SK_Version
    )
      AND
    (
      D_CALENDAR.Calendar_Date='01/Apr/2010'
    )
  GROUP BY
    D_PRODUCT.A_PRODUCTCODE,
    D_PRODUCT.A_PRODUCTNAME,
    D_PRODUCT.A_PRODUCTTYPE;

  And this query runs for hours without result.
  
  As far as I can tell, the two queries are functionally identical, so I left I was wondering if there is an additional optimization of the request being made by the first (ANSI at the bottom) query that is somehow not possible for the second syntax. Oracle would not 'smart' merge query in the view with the outer query in one case but not the other?
  
  I tried this create a materialized view (where the name), but the time to refresh an hour and a half is just too long to comfortably in our window of batch during the night. There are other optimizations of brute force, I could consider (staging of the motion of inline F_BOOKING_ON_DATE being the obvious one), but I'm afraid that if there is a fundamental incompatibility between the two join strategies that other similar problems can occur in our live environment without warning.
  
  Someone at - he had similar experiences?

  they are not.
  In ANSI variant it is LEFT JOIN in the Oracle variant, that I don't see

  Do you mean that the remote servers are running 8i?

  8i supported SQL 99 join syntax. So I would be quite surprised if forcing the instance of Oracle 9i local to do joins, representing the query Exchange plan.

• use the ansi join syntax

  From what I've been reading is preferable to use the new syntax (don't know how is it news)

  The ANSI join syntax was new to Oracle in Oracle 8i in 1998 - that is 15 years old.

  It can produce more readable code and is also much more readable and less human-source of errors for outer joins.

  The ANSI format allows an outer join between several tables in a way the old (+) syntax specific to oracle does not and introduced the JOIN FULL OUTER you should use very rarely.

  You should not use NATURAL JOIN in code - add columns not related to the tables involved can give very different results.

  There have not been important bugs for ANSI joins in Oracle from Oracle 10.2 set up about 8 years ago.

  As Paul says, the part on should be the criteria to join between the tables. Did clause should be the filtering of the joined tables.

  So assuming start_date and end_date in_property_id are variable

  SELECT resv_num, unit_date

  OF p_resv_unit ru

  INNER JOIN p_pm_unit_night pun

  ON pun.resv_unit_id = ru.resv_unit_id

  WHERE pun.property_id = in_property_id

  AND pun.unit_date BETWEEN start_date AND end_date

  AND pun.pm_unit_num = cvUnitNum;

  If start_date and end_date are the columns of p_resv_unit the query would be:

  SELECT resv_num, unit_date

  OF p_resv_unit ru

  INNER JOIN p_pm_unit_night pun

  ON pun.resv_unit_id = ru.resv_unit_id AND pun.unit_date BETWEEN ru.start_date AND ru.end_date

  WHERE pun.property_id = in_property_id

  AND pun.pm_unit_num = cvUnitNum;

  Inner join queries work with criteria in the wrong place, but they are harder to read. Outer joins do not work unless you put the criteria in the right place.

• old script with joins instead of ansi joins

  In 9i OWB when I generate the intermediate result script, it is generateing join in the OLD style as conditions below.
  a.ID = b.id (+)
  
  But in Oracle 11 g, it raises the join conditions in the Ansi joins as below
  a left outer join b on (a.id = b.id)
  
  
  Is there a way to generate the intermediate result script in an old style in OWB 11 g?

  You mix ANSI joins and the old joints. It's very confusing. Use all of one type or the other.
  >

  I want to know if the ANSI join is goig work properly or it will give me any Cartesian production information.

  What happens when try you it? Is it produces the results you want?

  Whenever you have any questions, post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data. Explain how you get these results from these data.
  Always tell what version of oracle you are using.
  See the FAQ forum {message identifier: = 9360002}

  Why the SELECT clause includes only NULL? Is that going to serve as an EXISTS subquery? If so, why bother to make the outer joins, and why do you care if it is a Cartesian product? What is the query to go for?
  For the purposes of debugging, you can include something that you see in the SELECT clause.

• JOIN the traditional ANSI JOIN VS.

  I am running Oracle 11 g R2 on my Win7 home x 64 Enterprise for a relational data base class.
  
  An exercise said to display the id of shopping cart, product id, product name and description of the product for all items ordered using a traditional join and an ANSI join.
  
  Traditional join:
  
  SELECT p.productname, p.description, bi.idproduct and bi.idbasket
  of BB_BASKETITEM bi, BB_PRODUCT p
  where bi.idproduct = p.idproduct;
  
  Join ANSI:
  
  SELECT productname, description, idproduct and idbasket
  of BB_BASKETITEM
  JOIN INTERNAL BB_PRODUCT
  using (idProduct);
  
  Both produce the same results.
  
  The next exercise said to add the name of the customer for both queries. I got the traditional join to work:
  
  SELECT s.lastname as "Customer Name", bi.idbasket, bi.idproduct, p.productname, p.description
  BI BB_BASKETITEM, BB_PRODUCT p, BB_SHOPPER s, BB_BASKET b
  where bi.idproduct = p.idproduct
  and bi.idbasket = b.idbasket
  and b.idshopper = s.idshopper;
  
  but I can't understand how to convert the traditional join in ANSI format.
  
  I checked the docs of the Oracle, but I can't find an example that uses more than two tables. I searched in the OTN forums, without a moment of ' AHA! '. One manual sorta, kinda discusses vs ANSI joins traditional.
  
  I have tried to provide the sample results, but all turned to mush in the preview. My apologies.

• Manually kick off of a simple pre-packaged ETL?

  Hello world
  
  I hope it's an easy question to answer. I want to run some ETLs manually through Workflow Manager. But when I do, they fail with the error "cannot find the settings file.
  
  Is there a way I can easily just kick off one of these ETLs for testing purposes?
  
  Thank you!
  
  -Joe

  There are two ways to achieve this.
  1 copy the parameter in the $pmserver / infa_shared / directory SrcFiles, then run the task.
  2. create new Sessions by cloning that you run from CAD and set the settings to the SQ, replacing the $$ LAST_UPDATE_DATE, $$ INITIAL_EXTRACT_DATE, etc. In this way it does not affect your SQ defined at the level of the mapping.
  Change connection settings to those defined in--> relational connections to point to the Source & target. Plug into a single workflow if you have all the dependencies

  Then the kickoff of the workflow.

• I try to use Hello but cannot join an active session, it is usually said 2 people are already signed.

  I am able to start a session, but I was not able to join by signing another pc usage. usually it is said there are already 2 users already signed.

  When you build the link, a small chat window should open at the bottom right. Which will automatically join you to the House.

  You can then share this link with anyone, or another computer, and they should be able to join.

  Note that for links build you, if you click on the link and have it in a tab, which currently stops anyone else to join.

  We are working on improving this in a future release.

• Update/join script to the oracle server

  Im trying to create a script using two tables in my oracle server.

  Developer SQL im trying to use these two different tables

  Table 1: conductorinfo

  Table2: calkva

  I want to join the two tables based on two fields:

  Condsize

  Condmatl

  (because the two tables have these fields) And based on these games of field, update the field conductorinfo of the table "calckva", because currently we have not these data in the conductorinfo table

  This is the script I came up with:

  UPDATE conductorinfo

  JOIN INTERNAL Calkva

  ON conductorinfo.condsize = calkva.condsize

  AND conductorinfo.condmatl = calkva.condmatl

  SET conductorinfo.calkva = calkva.calculatedkva

  WHERE conductorinfo.condsize = calkva.condsize

  AND conductorinfo.condmatl = calkva.condmatl

  Then I read this update/join cannot be used with an oracle server

  Any suggestions?

  Hello

  Here's a way you can use the MERGE:

  MERGE INTO dst conductorinfo

  With the HELP of calkva CBC

  WE (dst.condsize = src.condsize

  AND dst.condmatl = src.condmatl

  )

  WHEN MATCHED THEN UPDATE

  SET dst.calkva = dst.calculatedkva

• help with ansi joins

      INNER JOIN ap_invoice_distributions_v aid
      ON ( api.invoice_id              = aid.invoice_id

  LEFT OUTER JOIN ap_apply_prepays_v avp

  You join ap_apply_prepays_v three times, and you get the error, because you are still using the same alias.

  However, this triple join is incorrect. Try

  FROM    ap_invoices_v api
          JOIN ap_invoice_distributions_v aid
            ON (api.invoice_id = aid.invoice_id)
          JOIN ap_checks_v abc
            ON (abc.vendor_id = api.vendor_id)
          JOIN ap_invoice_payments abb
            ON (abc.check_id = abb.check_id
                AND abb.invoice_id = api.invoice_id)
          LEFT JOIN ap_unapply_prepays_v aup
            ON (aid.invoice_distribution_id = aup.prepay_distribution_id)
          LEFT JOIN ap_apply_prepays_v avp
            ON (api.invoice_id=avp.invoice_id
               AND aup.prepay_distribution_id = avp.invoice_distribution_id)
  WHERE   api.invoice_type_lookup_code = 'PREPAYMENT'
  AND     api.invoice_num = '5'

• Need help with the ANSI Join syntax

  Version: 11.1.0.7
  
  I have my select statement that returns 3000 lines and looks like
  

  select ..
  from tab1 a,tab2 b,tab3 c
  where a.c1=b.c1 and
  b.c2 = c.c2(+)
  and ...
  group by
  ..

  I want to convert it to ANSI SQL, because it must be able to Hibernate, and the developer says that Hibernate include only ANSI SQL. I tried something like
  

  select ..
  from tab1 a INNER JOIN tab2 b
  ON a.c1=b.c1 
  LEFT OUTER JOIN tab3 c
  ON b.c2=c.c2
  where ...
  group by
  ..

  I felt bad and it turned out to be the same. It returns no rows. Please help with the correct syntax.

  I'm not sure, sorry, because it's certainly the ANSI equivalent to the non-ANSI.

  Would you have examples of queries and data that you can reproduce the problem with, and that we could analyze?

  Published by: Seanmacgc on July 15, 2009 12:48

  If there is no Clause WHERE conditions in the original that are included in the ANSI version of the query in the WHERE Clause for the EXTERNAL table itself joined, then that could transform the JOIN JOIN internally, that is, all the filters on the EXTERNAL joined table should be included in the JOIN predicate - IT (b.c2 = c.2 AND c.c3 = 'X').
