Outer join without outer join
I'm trying to do is to learn how to do an outer join without specifying the outer join complete, right or left. Why? For most of the reasons for performance and gain a better understanding of the Oracle.Thank you
Charles.
Another option would be a scalar subquery in the select part, as:
SQL> select * from t;
ID DESCR
---------- ----------
1 T One
2 T Two
3 T Three
SQL> select * from t1;
ID DESCR
---------- ----------
1 T1 One
2 T1 Two
SQL> select t.*, t1.descr t1_descr
2 from t
3 left join t1
4 on t.id = t1.id;
ID DESCR T1_DESCR
---------- ---------- ----------
1 T One T1 One
2 T Two T1 Two
3 T Three
SQL> select t.*, (select t1.descr
2 from t1
3 where t.id = t1.id) t1_descr
4 from t;
ID DESCR T1_DESCR
---------- ---------- ----------
1 T One T1 One
2 T Two T1 Two
3 T Three
This can be faster if the correlated T1 column is indexed, and there is a "large" number of records in t which do not correspond with t1.

Left outer join without data in a table
I have two tables defined (see below). Emp table has given, and there is still no data in the table of Emp_Type! Now it is empty.
I want to write a query that returns the data from the tables, even if there is no data in the Emp_type table. I use a left outer join but it return nothing. Can anyone help?
create table EMP ( EMPID NUMBER(10,2), EMPNAME VARCHAR2(100) ); INSERT INTO emp (empid,empname) values (1, 'Mark'); INSERT INTO emp (empid,empname) values (2, 'Jason'); INSERT INTO emp (empid,empname) values (3, 'Kevin'); INSERT INTO emp (empid,empname) values (4, 'Drew'); INSERT INTO emp (empid,empname) values (5, 'Jessica'); INSERT INTO emp (empid,empname) values (6, 'Pena'); INSERT INTO emp (empid,empname) values (7, 'Roxanne'); create table EMP_Type ( ID NUMBER(10,2), EMPID NUMBER(10,2), TYPE_ID NUMBER(10,2), END_DATE DATE ); No data select * from emp e left outer join emp_Type t on e.empid = t.empid WHERE t.type_id = 1 and t.end_date is null;WHERE t.type_id = 1
will be ever true when table has no rows (or t.type_id is NULL?)

Bug with an outer join, or & Analytics function (or rownum)
Hello
Seems to be a combination of an outer join, OR and rownum confuses the CBO.
First request is without rownum, the second is with rownum.
The second query expects 203 t lines and never ends. It should behave the same as query 1, with 24 M lines.
Remove the GOLD clause query 2 allows him to behave as a query 1, with 24 M lines.
We never saw it? Is there a solution?

Your question is compounded because of the join condition that forces a level of nested loops, which means that the table should be fully analysed once for each line of conduct rowsource. You can either transform the join in an equijoin and allow a hash to run, or you join could materialize the subquery once.
Allow the hash join:

LEFT JOIN (SELECT hi.message_id, hi.update_dt

You may need to change the first condition to make sure that you select the correct subquery.
-edit
Not able to view a plan but you can invade the second join condition select and then the result of a subquery with a predicate according to your requirement. This should delay the or rating and leave only an equijoin (although rowsource return may be slightly larger than the opposite).

Hi Experts,
I have a requirement that says - see the chart for the past 10 days, regardless the presence data table in fact.
Lets consider an example - Time_dim product, are my dimension tables, Purchase_Order is my fact table.I did it for external Purchase_Order in left RPD with TIME_DIM and inner join with the PRODUCT table. and execution of query of exit-
Select T.Date, P.item, count (distinct PO.order_no)
TIME_DIM t, PRODUCT P, PURCHASE_ORDER PO
where T.date_key = PO.date_key
and P.item = in. agenda
and P.item = 'laptop ';The query generated by OBIEE left outer join, but when the condition P.item = "Notebook" included in the query, and if there are no orders for this product in one of the date, that date will not come in the result set.
the query to be generated by the OBIEE is-
Select T.Date, PO.item, count (distinct PO.order_no)
TIME_DIM t,.
(SELECT P.ITEM, IN. ORDER_NO
PRODUCT P, PO PURCHASE_ORDER
WHERE P.item = in. agenda
and P.item = 'Laptop') IN.
WHERE T.date_key = PO.date_key (+);How to design the RPD to achieve this. All pray to advise on this. Thanks in advance.
Thank you
ChantalHello
You are on 11.1.1.7?
I would say that your condition can be made without using external and maintenance of product and the standard between the FACT dimension, time inner join join.
If you enable your property analysis OBIEE "Include Null values" will automatically return all the elements of time and product matching your filter (so you'll need to add a filter on 'Date' to limit it to the last 10 days or you will have a unique day of your time dimension).
If you filter then on "Laptop", even if there is not a single value in order for "Laptop" in the last 10 days, he will be there on the screen.
Easy, clean and you keep your inner join between the facts and Dimensions.
Take a look at this example, I just did on SampleApp 406:
Selection of 12 months (year 2010) and a customer (id = 89) and income. The model has only an inner join. I activate the option "Include Null values" and here is the result.
A line with cells only empty because there is not a single revenue for customer 89 in 2010. This is exactly your condition.
Honestly, do not touch your model using the outer join, you will have more side effects than benefits. Every single scan will do the outer join and you'll have a lot of data 'empty' return of the DB (more large data set containing just the null values) and probably you need the outer join in 15 to 25% of your analysis.
Keep things simple, it will be faster and easier to maintain.

Hello world
I have an Obj from view to both entities like this:
SELECT t1.rowno, t2.type
OF table_ t1, t2 from table_2
WHERE t1.rowno (+) = t2.rowno
and t1.userId (+) =: bindVar
table_1 (Rowno, UserID)
table_2 (Rowno, type)
I have a table on this view of Obj on my page, when I add a new line of this view Obj, this line showed in the table while he should not appear (depending on where the view clause Obj).
according to this post https://forums.oracle.com/thread/2576480 I can use RowMatch, but here I don't know how to use an outer join in RowMatch.

I guess that joy cannot use matching line in this case as it only lines matching already in memory, but without an outer join. This must be done before.
What you can try is to build the sql criteria yourself and add it to the query. An example on how to do this at http://wp.me/pcBZk-5O
The example shows how to add a sql custom as a criterion.

Can join a Cluster of storage disk out of Maintenance DTS Mode to set up the profiles for a virtual machine storage policies?...

Seems weird it is (or may be) such disconnection of a memory of the profiles and the StorageClusters and the DTS?

At this point, I think that storage DRS and storage profiles are two technologies to separate and work independently, but what you suggest is a great idea-

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 , p.po_number , p.run_date , p.po_line_number , COUNT (i.farinvc_po) OVER ( PARTITION BY p.po_number , p.supplier_invoice_no ) 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 ) SELECT farinvc_invh_code , supplier_number , supplier_invoice_no , farinvc_item , farinvc_po , po_number , run_date , po_line_number FROM got_cardinal_sin_cnt WHERE cardinal_sin_cnt > 0 ORDER BY po_number , farinvc_item ; -

I have another list of selection mainly the list of months between two date value.

de)
Select add_months (to_date (' ' August 2012 ', ' MY YYYY' "), rownum-1) which_month

rownum < = months_between (to_date (' ' Oct 2012 ', ' MY YYYY' "), add_months (to_date (' ' August 2012", "MY YYYY"), - 1))
order of which_month)
The query result is as below
DISPLAY_MONTH
AUGUST 2012
SEP 2012
OCT 2012
Is it possible I can join these two select statement above to generate a comparable result:
Days of month Phase number Avg
August 2012 Phase One 8.666
Sep 2012 Phase One 7.66
Oct 2012 Phase One 5,66
August 2012 Phase two 8.666
Sep 2012 Phase two 7.66
Oct 2012 Phase two 5,66
August 2012 Phase three 8.666
Sep 2012 Phase three 7.66
Oct 2012 Phase three 5,66
Or
Days of month Phase number Avg
August 2012 Phase One 8.666
August 2012 Phase two 7.66
August 2012 Phase three 5,66
Sep 2012 Phase One 8.666

Sep 2012 Phase three 5,66
Oct 2012 Phase One 8.666
Oct 2012 Phase two 7.66
Oct 2012 Phase three 5,66
And it can be controlled by Phase number or month.
My other colleague suggested I should use a left outer join, but after having tried many ways, I'm still stuck.
I tried select is

END)
(-ph.date_started + 1) / count (def.def_id) as avg_days
Ph phase_membership
inner join court_engagement this on ph.mpm_eng_id = ce.engagement_id

and ph.active = 1
and UPPER (ce.court_name) LIKE '% '.
To_char (ph.date_finished, 'MY YYYY'), group (phase_number) rollup) b
On a.display_month = b.join_month
but then I get an error

I need to view a report on the APEX with option for people to download at least format CSV.
Already 1 inteactive report in the page, so I don't think adds another interactive report without using the iframe trick.
If any of you have any ideas, please help.
Thank you very much.
AnnHello Ann,.
Frank has done a very good job. I am also impressed.
Is in regard to your correction to his question, the problem is on this replacement you did
last_day(TO_DATE(am.which_month,'MON YYYY'))AM.which_month is already a date type, and you don't need to convert it to this day.
Here is the correct way:last_day(am.which_month)There are also sometimes with the data you've posted have no line for this month. So I also added a function NVL to display 0 under avg_days for these cases.
Here is my corrected query:
DEFINE startmonth = "Aug 2012"; DEFINE endmonth = "Oct 2012"; WITH all_months AS ( SELECT ADD_MONTHS(to_date('&startmonth','MON YYYY'), ROWNUM-1) AS which_month , ADD_MONTHS(to_date('&startmonth','MON YYYY'), ROWNUM ) AS next_month from all_objects where rownum <= months_between(to_date('&endmonth','MON YYYY'), add_months(to_date('&startmonth','MON YYYY'), -1)) ) SELECT TO_CHAR (am.which_month, 'Mon YYYY') AS month , ph.phase_number , NVL(sum ( (CASE WHEN ph.date_finished IS NULL OR ph.date_finished > last_day(am.which_month) THEN last_day(am.which_month) ELSE ph.date_finished END ) - ph.date_started + 1 ) / count(def.def_id), 0) as avg_days FROM all_months am LEFT OUTER JOIN a_phase_membership ph PARTITION BY (ph.phase_number) ON am.which_month <= ph.date_started AND am.next_month > ph.date_started AND ph.date_started <= last_day(am.which_month) -- May not be needed AND ph.active = 1 LEFT OUTER JOIN a_engagement ce ON ph.mpm_eng_id = ce.engagement_id AND ce.court_name IS NOT NULL -- or something involving LIKE LEFT OUTER join a_defendant def ON ce.defendant_id = def.def_id AND def.active = 1 GROUP BY ROLLUP(phase_number, am.which_month) ORDER BY am.which_month , ph.phase_number ; The output is: MONTH PHASE_NUMBER AVG_DAYS -------- -------------------- ---------- Aug 2012 PHASE ONE 0 Aug 2012 PHASE THREE 0 Aug 2012 PHASE TWO 0 Sep 2012 PHASE ONE 12 Sep 2012 PHASE THREE 1 Sep 2012 PHASE TWO 9 Oct 2012 PHASE ONE 8 Oct 2012 PHASE THREE 0 Oct 2012 PHASE TWO 14 PHASE ONE 11 PHASE THREE 1 PHASE TWO 11.5 9.71428571I don't know if that's really what you want. In the case check it and let me know.

Hi, I am new to oracle and I worked this request for reports for about 2 weeks, please take a look at my request

put desired option on would show all archives on mtl_material_transactions with null values
so I put the symbol of the outer join right?
BTW
I tried to put the (+) sign on various locations but it still not good and I am really at a lossHello
Whenever you have any questions, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and the desired results from these data. I know that's not always easy, but it is really necessary. Compounds that, I do not understand your problem.
It could be useful that simplify you the problem. If you were not interested in, say, the mta, gcc, tables msib and ood, would you still have the same problem? If so, forget all these tables and just after, CREATE TABLE and INSERT statements for the remaining tables and the results you want from this data.
Explain, using specific examples, how you get these results from these data.
Always tell what version of Oracle you are using.The query you posted will not exclude any line of mmt just because it doesn't have a corresponding line in the mtr; That's what the condition:
and mmt.reason_id=mtr.reason_id(+)but it will exclude mmt lines if they do not have matching rows in other tables. Maybe you need + plus join and may under certain conditions non-join, such as conditions
gcc.segment2 (+) = :P_ACCOUNTToo much. It's just a guess. Without seeing your sample data and the correct results, you should get from this data, I can't say.

Different Outer Join query result

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?

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 sayFPOVR.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 +.

Hi all
I have issues with the help of ANSI LEFT JOIN compared to Oracle (+). Below test I did the same thing.
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.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'
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.Published by: Kim Berg Hansen on September 23, 2011 08:03

Problem with XMLTABLE and LEFT OUTER JOIN

I have a problem with XMLTABLE and LEFT OUTER JOIN, in 11g it returns the correct result, but in 10g it doesn't, it is illustrated as a INNER JOIN.
This is all nice, now the problem:SELECT * FROM v$version; Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production PL/SQL Release 11.2.0.1.0 - Production "CORE 11.2.0.1.0 Production" TNS for Linux: Version 11.2.0.1.0 - Production NLSRTL Version 11.2.0.1.0 - Production --test for 11g CREATE TABLE XML_TEST( ID NUMBER(2,0), XML XMLTYPE ); INSERT INTO XML_TEST VALUES ( 1, XMLTYPE (' <msg> <data> <fields> <id>g1</id> <dat>data1</dat> </fields> </data> </msg> ') ); INSERT INTO XML_TEST VALUES ( 2, XMLTYPE (' <msg> <data> <fields> <id>g2</id> <dat>data2</dat> </fields> </data> </msg> ') ); INSERT INTO XML_TEST VALUES ( 3, XMLTYPE (' <msg> <data> <fields> <id>g3</id> <dat>data3</dat> </fields> <fields> <id>g4</id> <dat>data4</dat> </fields> <fields> <dat>data5</dat> </fields> </data> </msg> ') ); SELECT t.id, x.dat, y.seqno, y.id_real FROM xml_test t, XMLTABLE ( '/msg/data/fields' passing t.xml columns dat VARCHAR2(10) path 'dat', id XMLTYPE path 'id' )x LEFT OUTER JOIN XMLTABLE ( 'id' passing x.id columns seqno FOR ORDINALITY, id_real VARCHAR2(30) PATH '.' )y ON 1=1 ; ID DAT SEQNO ID_REAL -- ----- ----- ------- 1 data1 1 g1 2 data2 1 g2 3 data3 1 g3 3 data4 1 g4 3 data5

Is this a bug?, Metalink says that sometimes we can have an ORA-0600, but in this case there is no error results returned, just incorrect.
Help, please.
Kind regards.What about try the original Oracle method for outer joins? Using (+) without the extra space
XMLTABLE(...COLUMNS ... id XMLTYPE PATH ... ) x, XMLTABLE(... PASSING x.id ...) (+) y
