The table can be outer joined to a single other table

Hello

Using oracle 11.2.0.3

Select *.

from tablea

tableb

tablec

where tablea.col = tableb.col (+)

and tablea.col = tablec.col (+)

throws error table can be attached externally to another table.

What is the best/recommended way to allow more than one outer join table?

Thank you

Hello

Use ANSI join rating:

SELECT *.

FROM tablea a

LEFT OUTER JOIN tableb b ON a.col = b.col

LEFT OUTER JOIN tablec c ON a.col = c.col

;

Are you sure the query you posted is really what you're running?  The query you posted shoulddn can't cause the error, because the tableb and tablec are each being only outside attached to 1 other table.  You get the error if the + signs were reversed in the two conditions.

In any case, I suggest to use the ANSI syntax for all joins, especially outer joins.  You will never get the error "Table can be external attached to a single other table", and which is one of the reasons why it is better.

I hope that answers your question.

If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

Explain, using specific examples, how you get these results from these data.

Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  • You can force BI outer join in w/o logical SQL Anwser in the Advanced tab

    In the repository of BI, we Protocol, region, Site of Protocol, Dimension of the object and a table of facts containing the physical tables Protocol, region, site and subject as a source in MDB.

    The relationship is that a protocol can have 0, n regions, region 0, n sites and a site 0, n subject, with the fact table of the region contains Protocol WID and done Site contains the Protocol and Feds region, subject is contains the Protocol, the region and Site Feds.

    In reporting on the Protocol and the region, BI users would like to have all the protocols appear in the report, without worrying if a protocol contains regions or not. Even as the Protocol-region-Site reports, etc. I can create these reports with SQL logic in the Advanced tab to force BI joins external Protocol, region or Site, etc.. However, users of BI would be difficult to write these SQLs.

    It seems to me that BI server always uses an inner join in the SQLs generated when the user selects the attributes of Protocol, region and Sites, etc. I played with constant implicit approach.

    I know that I can use outer join to define the logic Table Source in the layer of MDB. Would this tangle Protocol, region and site, tables etc. in MDB? What is the best practice to the MDB template when you want compatible outer join?

    Is there a way to force the BI server to generate outer join in the answers?

    Thanks in advance,

    Shi-ning

    Joins using external in the layer MDB is not recommended because it brings in the tables in the query and also impact performance. The right way to handle this scenario is the ETL.

    Add a record to the dimension tables with 0 for the ROW_WID and NULL values for the rest of the columns
    All of fact records without valid WID values for the dimension of research must have a value of 0 instead
    Now when we try to do an INTERNAL JOIN between the fact and any dimension, even those made documents that donot have a valid WID value will also be part of the result. It is essentially an OUTER JOIN operation.

  • Why left outer join with a table gives me more lines?

    Hi gurus,

    I can see "view_a" and a table 'table_a '.

    view_a a county of 100 lines. Now, when I left outer join that discovers with a 'table_a', I expect all 100 lines.

    However, I'm more than 100 lines. Is it still possible?

    Also even to analyze these situations, how can I move forward?

    Because it is very high volumn of sight and takes longer to run.

    Select count (*) view_a, view_b

    where view_a.col1 = view_b.col1 (+)

    and view_a.col2 = view_b.col2 (+);

    No do you expect? You get ALL the child rows that belong to the parent company. Otherwise, how could it possibly work?

    The OUTER join includes lines where the parent row exists but there is NO child line as others have shown.

    Outer joins

    Outer join extends the result of a simple join. Outer join returns all rows that satisfy the join condition and also returns some or all rows in a table for which no line of the other meet the join condition.

    Get more lines to exist in one of the paintings is a basic necessity. It usually has NOTHING to with the question of whether you have an outside to join or not.

  • Problem with the implementation of Outer JOIN

    Hello Guru,

    Here's my scenario. I know that this can be achieved in several ways. But I need this in a single in aid Of JOINS EXTERNALrequest.

    I have two tables namely masters and transactions table. I need to join two columns (trx_name, trx_type) of the two tables and the need for all transactions. Part the trickiest is off 2 join columns, one column can be NULL in the main table.

    Script TABLES:

    create master table (mstr_no number, trx_name varchar2 (100), trx_type varchar2 (100), trx_module varchar2 (100));

    insert into masters values (1, 'yyyy', 'simple', 'cont');
    insert into masters values (2, 'bbbb', < NULL >, "cust");
    insert into masters values (3, 'yyyy', 'triple', "cont1");

    create table transaction (trx_no number, trx_name varchar2 (100), trx_type varchar2 (100));

    Insert in transaction values (1, 'yyyy', 'simple');
    Insert the transaction values (2, 'bbbb', 'double');
    Insert in transaction values (3, 'yyyy', 'triple');
    Insert in transaction values (4, 'cccc', 'purple');
    commit;

    I need output like below.

    1, 'yyyy', 'simple', 'cont '.
    2, 'bbbb', < NULL >, * "cust."
    3, 'yyyy', 'triple', "cont1".
    4, 'cccc', 'purple', < NULL >

    I need to join trx_name & trx_type in the two tables. Even if one of the column is null in the main table (mstr_no = 2), I have need of the corresponding value of trx_module since trx_name made match.


    My query:
    Select a.*, b.trx_module of transaction a, master b
    where a.trx_name = b.trx_name (+)
    and a.trx_type = NVL (b.trx_type (+), 'NULL')
    order of a.trx_no

    Appreciate your help.

    Re-reading my answer, I see that a short explanation might be useful: the query uses two outer joins: first masters lines with the name and type are joined, and then type the lines with missing. Him coalesce work to choose the most relevant information of module.

    Hello

    Want results from an inner join to match identifiers, but the results of an outer join for identifiers that are not?  In other words, you want to include the rows of the table I only when one of the following is true:

    The line of table I have ticked all the boxes, or

    No line in not table i with the same ID meets all conditions

    ?

    If so, here's a way to do it:

    WITH got_rnk AS

    (

    Select i.ids, i.start_date, i.cust_type

    , nvl2 (ii.ids, i.amount, 0) as gross_amount

    , i.amount + nvl (ii.amount, 0) as net_amount

    dense_rank () over (partition of i.ids

    order of nvl2 (ii.ids, 'A', 'B')

    ) as rnk

    I have test

    (in left outer join

    SELECT ID, amount

    of the test

    where status ('R', 'J')

    ) ii on i.ids = ii.ids

    and i.cust_type in (4, 78, 91, 2, 4, 8)

    and i.start_date between to_date (January 1, 2014 ", 'dd-mon-yyyy')

    In the query above 1, t1 is the required table (LEFT OUTER JOIN means the table on the LEFT is needed, and the other table is optional).

    Query 3 is the way to do the same in the old notation.

    If you use the old notation of outer join, the + sign is used by reference to the table as an option.  It should always apply for t1 or t2, not sometimes one and sometimes the other, which is what you do in the application 2.  In the State:

    T1. B = T2. B ( + )

    you say that t2 is optional; in the other condition

    T1. B (+) = 20

    you say that t1 is optional.  I don't know why that does not raise an error.  Apparently, it is just to ignore the sign in this last condition.

  • Outer joins are equijoins and?

    Difference between them is a join with external FPOVR. LEVEL_VALUE and hard coded value. Why these query above return different results even if the outer join is made with hard coded in value?

    and fpo.profile_option_name = 'GL_SET_OF_BKS_ID. '

    But the following query does not give the expected result.

    Select DECODE (FPOVR. PROFILE_OPTION_VALUE,

    and fpo.profile_option_name = 'GL_SET_OF_BKS_ID. '

    Difference between them is a join with external FPOVR. LEVEL_VALUE and hard coded value.

    In fact, the difference is that the condition relating to FPOVR. LEVEL_VALUE to 21533 is part of the outer join condition in the first query, but it is not in the second query.

    Why these query above return different results even if the outer join is made with hard coded in value?

    When you say

    FPOVR.LEVEL_VALUE(+) = 21533
    

    (with a sign +) only the lines of fpovr with level_value = 21533 will join the other table. If there is no such line in fpovr, then a row of output will be generatedd for each row in the other table anyway.
    When you say

    FPOVR.LEVEL_VALUE = 21533
    

    (without a sign +) then the outer join is made using the other conditions, which may result in some lines of the other table who appear in the result set with NULL in places where the values of fpovr would normally appear. Then when the join is complete, the condition is applied, and all these lines with the NULL value instead of fpovr.level_value are deleted because they do not meet the condition "FPOVR. LEVEL_VALUE = 21533 ". The effect is identical to an inner join.

    When you use the old rating of outer join (i.e. with signs +), if any condition involving the fpovr table has a + sign, and then all of the conditions involving table fpovr must have a + sign, otherwise the result will be the same if none of the conditions were a sign +.

  • The merged clips appear out-of-sync indicators while in sync

    So I have this weird problem with merged clips showing out-of-sync indicators while in fact, the audio is synchronized.

    Let me explain first the workflow for this feature;

    -Set of 6 K RED footage gets converted to 1080 p Prores Proxy

    -All the proxies and separate audio files are imported into a project file 'Master and Sync' (I use it to synchronize and merge clips as well as rename them)

    -When everything is synchronized, merged and renamed, they are placed in their corresponding scene number folder

    -J' I then open my project file 'Edit' and in the media browser, browse to the file "Master and Sync" project.

    -J' have drag and drop clips/merged records newly created the 'Master Sync' in the mediabrowser, in my project 'change '.

    -J' I change with them and everything works as expected.

    The issue comes in when I try to import a sequence edited of my Deputy Editor-in-Chief.

    -We work with the latest version of first

    -We are working on our own systems at home, but both have local access to all the images that we work with.

    -We have a record of sharing creative cloud where our editing projects are located and saved as well as the project "Master and Sync.

    -When my assistant has completed a first Assembly of a scene I navigate to his project to change the media browser when changing my own project is open.

    -J' I find the finished sequence and drag and drop it into my own project to change .

    And at that time there almost every single clip shows the out-of-sync indicator, but when I play the sequence everything is synchronized. I checked with my assistend maybe if its sequence shows also these indicators, but it is not. So it only seems to happen when I import its sequences. I tried ' display indicator out of sync clips unrelated " in the preferences, but without success.

    out of sync indicators.png

    To add a comment to the audio to video synchronization. I had to make up for a lot of audio clips by a 1 or a couple of images manually because they turned with timecode jamming and not gen-lock. It is so true that technically the audio can be out of sync before their merger all but as you can see on the screenshot the indicators show a shift much larger than 1 or two images (I think the max lag that I got was 9 frames).

    All suggestions are welcome and I really hope I'm overlooking something rather than finding a bug!

    Thank you!

    So, I just got a phone call from Adobe. Technology Adobe told me that he had tested this configuration to confirm that it is seeing the same thing I am. Unfortunately, it has been. He also told me that it is a limitation instead of bug. Is because my assistant and I are working on two different systems and no access don't not on the same physical hard disk and so do not have access to the "exact" same media.

    It would be no problem if we worked on different systems, but to access media on the shared storage.

    The shame if this is considered to be a limitation rather than a bug. Seems to me it is repairable but, Hey! I'm just a simple editor and no programmer so it might be more difficult.

  • Outer join does not

    Hello

    Pls help me my request. I tried the following, but it does not give the expected results.

    Tab1
    EmplId, RepDt, Code, Hrs

    1/100,1/2009,200,4

    1/100,1/2009,200,6
    200,1/1/2009,200,3

    I need output like this - 4 rows - need of all the rows from TAB1 when EMPLID, REPDT match TAB2, field values: need at a time when Code is also, when emlid, correspondence of the date, the Code missing so need A hrs, display ZERO as Tab2 hours.

    1/100,1/2009,199,8,0 - did not exist is not in tab2, so hrs Tab2 is ZERO
    1/100,1/2009,200,4,6 - Emplid, RepDt, Code match existence in Tab2, Tab1 Hrs 8, 6 Hrs Tab2
    1/100,1/2009,255,3,0 - did not exist is not in Tab2, so Tab2 hrs is equal to ZERO
    200,1/1/2009,200,4,3 - Emplid, Repdt, Code Match existed in Tab2, 4 Hrs of Tab1, Tab2 3 Hrs

    We are in 10g, Oracle.

    I tried the following
    T1. EmplId = T2.emplid AND T1.repdt = T2.repdt AND T1.code, T2.code = (+) - returns the unique corresponding lines, 2 rows.

    Pls help.

    Thanks in advance.

    Hello

    See the Boneist first message in this thread:

    select t1.emplid, t1.repdt, t1.code, t1.hrs, nvl(t2.hrs, 0)
    from   tab1 t1,
           tab2 t2
    where  t1.emplid = t2.emplid (+)
    and    t1.repdt = t2.repdt (+)
    and    t1.code = t2.code (+)
    and    (t1.emplid, t1.repdt) in (select emplid, repdt
                                     from   tab2)
    order by repdt, emplid, code;
    

    As Boneist said, this fact corresponds to option (b)
    "(b) do just an outer join, with a condition EXISTS (or IN) in the WHERE clause to find corresponding repdts.
    The

    (+)
    

    an outer join are signs.

  • Configure the network management grayed out in DCUI

    Configure the network management grayed out in DCUI and some other options are grayed out and network management IP is 0.0.0.0

    Seems that you have not any management VMkernel port or they may have been removed. You may need to check the same.

    Run esxcli list of network ip interface to check if there is no VMKernels.

    It does not generate re no output if NO vmkernel port is available.

    If no. VMkernel ports then follow the below to re-create the management VMkernel port group.

    esxcli network ip interface add-i = vmk0 Pei = "network management - M = 'MAC address' ' to create a VMKernel for management." Make sure the right to MAC address of the uplink is mentioned.

    And make sure that it is a unique vmk, does not correspond to a vmk existing (vmk0, vmk1, vmk2).

    Once the Port is created, you should be able to configure networking on the DCUI

    Hope it will be useful.
