  Hello

  Let me assure you that I understand.
  Last time, we were looking for the PO_NUMBERs who have been partially put into correspondence , i.e. groups of rows in the order table with the same po_number, which some had corresponding lines in the table Bill, and some of whom have not. It was essential that there is at least 1 line and 1 row without connections with the same purchase order.
  Now that you are interested SUPPLIER_INVOICE_NOs who are partially paired, i.e. groups of rows in the table of po with the same po_number and supplier_invoice_no, some of which have corresponding lines in the invoice table, and some are not. ("Supplier_Invoice_No" is quite a mouthful. "We'll abbreviate as sin in the future.) However, the final selection is based on po_numbers: If a po_number has partially matched sins, then we are interested all po_number. For example, the result set must include = 529132260 SIN, even if that sin is completely, because there is a partially matching sin (529137831) with the same po_number (P0142245).

  As this problem revolves around partially matching sins, let's call them Cardinal sins . We can calculate match_cnt and total_cnt based NAS as well as po_number. Then, we can use another analytic function so see if the po_number has all cardinal_sins, like this:

  WITH    joined_data     AS
  (
       SELECT     i.farinvc_invh_code
       ,     p.supplier_number
       ,     p.supplier_invoice_no
       ,     i.farinvc_item
       ,     i.farinvc_po

                             )     AS match_cnt
       ,     COUNT (*)           OVER ( PARTITION BY  p.po_number
                                          ,                  p.supplier_invoice_no
                                        )     AS total_cnt
       FROM           po       p
       LEFT OUTER JOIN  invoice  i  ON   i.farinvc_po    = p.po_number
                                    AND  i.farinvc_item  = p.po_line_number
  )
  ,     got_cardinal_sin_cnt     AS
  (
       SELECT  joined_data.*
       ,     SUM ( CASE
                      WHEN  match_cnt  >= 1
                   AND     match_cnt  <  total_cnt
                   THEN  1
                  END
                ) OVER (PARTITION BY  po_number)     AS cardinal_sin_cnt
       FROM    joined_data

  ,       run_date

  You should not outer join... That should do it...

  select ID , (select count(PID) from table2  t2 where t2.id = t1.id) , (select count(PARID) from table3  t3 where t3.id = t1.id)
  from table1
  

• Need help with the JOIN condition

  I have two tables tb1 and tb2. They join on two columns, namely, plan_name and activity_name. I must, however, ensure the following conditions by joining:
  
  1. pick up all the records that link between tb1 and tb2.
  
  2. If the tb1.plan_name is "Activity Adhoc" and then choose the lines that converge with tb2. Also pick up lines that do not join with tb2 where plan_name = 'Ad hoc activity'. For example:
  TB1 have 2 folders with plan_name Adhoc Acitivity
  plan_name activity_name
  Adhoc activity A1
  Adhoc activity A2
  TB2 has 1 plug with plan_name activity Adhoc
  plan_name activity_name
  Adhoc activity A1
  
  then the two records of tb1 should be taken. in other Assembly documents where plan_name <>"Adhoc Acitivity" should also be taken

  with tb1 as
  (
  select 'Adhoc Activity' plan_name,'A1' activity_name from dual union all
  select 'Adhoc Activity' plan_name,'A2' activity_name from dual union all
  select 'another Activity' plan_name,'A2' activity_name from  dual union all
  select 'Some another Activity' plan_name,'A2' activity_name from dual
  ),
  tb2 as
  (
  select 'Adhoc Activity' plan_name,'A1' activity_name from  dual union all
  --select 'Adhoc Activity' plan_name,'A2' activity_name dual union all
  select 'another Activity' plan_name,'A2' activity_name from  dual --union all
  --select 'Some another Activity' plan_name,'A2' activity_name dual
  )
  select *
  from(
     select a.plan_name a_plan_name,b.plan_name b_plan_name
     from tb1 a,tb2 b
     where a.plan_name = b.plan_name(+)
     and a.activity_name = b.activity_name(+)
       )
  where (a_plan_name = 'Adhoc Activity'  or b_plan_name is not null);
  
  A_PLAN_NAME           B_PLAN_NAME

• Need help with outer join

  Hello

  I have a requirement in which I need to get data from a third table where a date of the third table is higher than a date in the second array.

  Ex:

  SELECT t1.column1, t3.column2
  FROM t1, t2, t3
  WHERE t1.id = t2.foreign_id
  AND t1.id ( + ) = t3.foreign_id
  AND t3.some_date_column > t2.another_date_column
  
  

  However, using the query above returns no results if the date condition is not met. I still need to show t1.column1 and a null t3.column2.

  How should I do this?

  Thank you

  Allen

  Edit: Added information about the requirement.

  Hi Allen

  1. SELECT t1.column1, t3.column2
  2. T1, t2, t3
  3. WHERE t1.id = t2.foreign_id
  4. AND t1.id = t3.foreign_id (+)
  5. AND t3.some_date_column (+) > t2.another_date_column

  I guess that this t1.column1 must not be null. Or am I wrong? The + sign must be placed on the side where draws are accepted. You must repeat it for each condition on the table.

  Alternativlely you can use the LEFT OUT JOIN syntax. If the two columns are allowed null you need a FULL OUTER JOIN.

  BTW: The join to t2 is not required if a refefernce constraint forced.

• Help with Inner join problem

  The following query works fine as long as there is a value in the subID field, which is the end of the inner join statement. If the subID is empty then no data is output, even if it is there. Try as I may, I can't do the right solution in which the statement to get the data to show without the subID. What Miss me?

  < name cfquery = "getInfo" datasource = "#application.database #" >

  Select page_id, pageName, pages.content, pages.cat_id, pages.seo_title, pages.seo_desc, pages.seo_words, pages.h1_title, pages.pic, pages.brochure, pa ges.video, catagories.catagory, subcat.subID, subcat.sub_category

  (page INNER JOIN categories ON pages.cat_id = catagories.cat_id) INNER JOIN subcat ON pages.subID = subcat.subID

  where pages.page_id = #page_id #.

  < / cfquery >

  Rick,

  Looks like you need a LEFT OUTER join to the table "subcat", so that all the records for the 'pages' and 'categories' are returned, even if no records matching "subcat" doesn't exist.  Joins INTERNAL returns only the selected records when both sides of the join statement tables have matching values, while you will get a join OUTER LEFT (sometimes also known simply as a LEFT JOIN) * everything * selected records from the table on the left side of the join statement, no matter if he adapt records from the table on the right side of the join statement.  When there is no corresponding record in the table on the right side of the join statement, all the columns in your SELECT clause that come from the table on the right side of the join statement will contain NULL values.

  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.

• 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

  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

  (+)

• 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').

• Problem with ANSI OUTER JOIN

  Hi all
  
  I have issues with the help of ANSI LEFT JOIN compared to Oracle (+). Below test I did the same thing.

        create table emp (emp_id number(10), emp_name varchar2(50));
        create table courses (course_id number(10), emp_id number(10), course_name varchar2(50));
        
        INSERT INTO EMP values(1,'A');
        INSERT INTO EMP values(2,'B');
        INSERT INTO EMP values(3,'C');
  
        INSERT INTO COURSES values(1,1,'ORACLE');
        INSERT INTO COURSES values(2,1,'JAVA');
        INSERT INTO COURSES values(3,3,'C#');
  
        --*Query 1
        SELECT a.*, b.*
        FROM EMP a  LEFT JOIN COURSES b 
        ON a.emp_id = b.emp_id
        AND a.emp_name = 'A'
  
        --*Query 2      
        SELECT a.*, b.* 
        FROM EMP a, COURSES b 
        where a.emp_id = b.emp_id(+)
        and a.emp_name = 'A'

  Here Query1 return all records of 4 same records regardless of emp_name = 'A' where as Query2 returns 2 records of ep_name = 'A' which is correct.
  
  Is this correct? I'm confused if you use the standard ANSI OUTER JOINS or not.
  
  I am using Oracle 11g
  
  Thank you.

  Change your AND WHERE, in the style of ANSI, select:

  SELECT a.*, b.*
  FROM EMP a  LEFT JOIN COURSES b
  ON a.emp_id = b.emp_id
  WHERE a.emp_name = 'A'
  

  Filters in the clause are those who use the (+) in the Oracle syntax.
  Filters WITHOUT (+) in the Oracle syntax should be in the WHERE clause using the ANSI syntax.

• Need help with joins Oracle

  
  Hi all

  Any new on Oracle Sql and I need expert input to solve a problem I have to join Oracle.

  Have a requirement as below, my reading of request as below.

  SELECT A.GCI, B.LOB_IND, B.CED_ID, C. LOB_DESCR OF CUSTOMER, CUSTOMER b, C from LOB

  WHERE A.PRIMARY_CED = B.CED_ID (+)

  AND B.LOB = C.LOB_DESCR (+)

  AND B.LOB_IND (+) = 'Y '.

  AND A.GCI IN

  (

  '339492963',

  '339850821');

  Output current:

  GCI LOB_IND CED_ID LOB_DESCR

  339850821 Y 7905108 banking services for businesses

  Null Null null 339492963

  Power required:

  GCI LOB_IND CED_ID LOB_DESCR

  339850821 Y 7905108 banking services for businesses

  339492963 7859659 null null

  In the table B (CLIENT) for a ced_id there will be several entries.

  Select ced_id, LOB_IND from CLIENT b where b.ced_id = '7905108';

  ced_id LOB_IND

  7905108 IS

  7905108 null

  7905108 null

  Select ced_id, LOB_IND from CLIENT b where b.ced_id = 7859659;

  ced_id LOB_IND

  7859659 null

  7859659 null

  so when writing of the main request, I took B.LOB_IND (+) = 'Y' condition, since I added this condition and catches of outer join.

  the ced_id for "7859659" is not coming in the query below.

  SELECT A.GCI, B.LOB_IND, B.CED_ID, C. LOB_DESCR OF CUSTOMER, CUSTOMER b, C from LOB

  WHERE A.PRIMARY_CED = B.CED_ID (+)

  AND B.LOB = C.LOB_DESCR (+)

  AND B.LOB_IND (+) = 'Y '.

  AND A.GCI IN

  (

  '339492963',

  '339850821');

  Output current:

  GCI LOB_IND CED_ID LOB_DESCR

  339850821 Y 7905108 banking services for businesses

  Null Null null 339492963

  Is it possible that the query can be modified to get the below output with CED_ID for B.LOB_IND-> case of Null.

  Power required:

  GCI LOB_IND LOB LOB_DESCR

  339850821 Y 7905108 banking services for businesses

  339492963 7859659

  Your entered very necessary.

  Thank you

  Be great if someone could have provide some suggestions.

  Use ANSI joins:

  SELECT A.GCI, B.LOB_IND,
  B.CED_ID,
  C.LOB_DESCR
  CUSTOMER A
  LEFT JOIN
  CLIENT b, C from LOB
  ON)
  A.GCI IN)

  )
  AND
  A.PRIMARY_CED = B.CED_ID
  AND
  B.LOB_IND = 'Y '.

  LEFT JOIN
  C LOB

  Thanks for posting the CREATE TABLE and INSERT.
  It is more useful if you post the code that can be run without modification. You did not semicolons after INSERTION instructions.

  Three questions:
  (1) I don't want to return results where table_name = "table1". I can't get this to work.

  What have you tried? Post your best attempt.
  Here's one way:

  SELECT    u.table_name
  ,        u.column_name
  ,        c.constraint_name
  FROM             user_tab_col_test      u
  LEFT OUTER JOIN  all_cons_columns_test  c
                          ON    u.table_name     = c.table_name
                 AND   u.column_name     = c.column_name
                 AND   c.constraint_name IN ('primary')
  WHERE       u.table_name     = 'table1'          --  *****  NEW  *****
  ORDER BY  u.table_name
  ,            u.column_name
  ;
  

  You would not put this condition in the clause; who controls what is considered as a match between the tables, and "u LEFT OUTER JOIN c" means show all lines of u, even if they do not have a match in the c.

  (2) is my proper request and this is the best way to return my desired results? For example, I want all of the columns of user_tab_col_test and I want to only display the constraint_name from all_cons_columns_test argument if the argument constraint_name = 'primary '.

  Basically, this application is very well.
  It displays all the columns of user_tab_col_test; missing data_type. Just add u.data_type to the SELECT clause, or change the SELECT clause

  SELECT    u.*
  ,         c.constraint_name
  

  (3) will be the synatx be the same if I need to join a third table to all_cons_columns_test?

  Do you mean "" * add * one-third * column * to all_cons_columns_test '? "
  It depends on what results you want. Post new CREATE TABLE and INSERT and instructions the results you want new data.
  Most likely, the basic structure of what you've written will remain exactly the same.

• 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.

• Need help with join

  I have a problem with the join, I try to use it to eliminate the mass number of path layers and sublayers I. Everything is already connected by anchor point but they have all of the separate layers and it is heavy for shipping and export.

  And that's what he keeps to:

  

  Any suggestion is welcome.

  dmuir,

  You can reach only two segments of track at the same time, so that each (no end) Anchor Point has only two adjacent segments.

  You can combine paths and creating paths compound and other things, but you're stuck with a number of roads as building blocks.
