Outer join problem
Hi, I have a problem with my query:
SELECT t1.step, t2.name FROM RIGHT JOIN t1 t2 ON t2.step = t1.step
I have two tables, small t1 and t2 great.
table T1 (7 lines):
name of the step
1 a
2B
3 C
4 D
5 e
$4
7 g
table T2 (10000 lines);
name of the step ID
100 1A
101 2B
102 3 c
103 4 D
104 5th
105 1A
106 2 b
107 3 c
108 d 4
109 5 e
110 1A
111 2B
112 3 c
113 4 D
114 5 e
115 1A
116 2B
117 c 3
118 d 4
119 5th
… … ..
I want external right to join them, and have values in t2.name NULL and the range of steps (1-7).
My query returns this:
name of the step
1 a
2B
3 C
4 D
5 e
1 a
2B
3 C
4 D
5 e
1 a
2B
3 C
4 D
5 e
....
Thank you.
So there is indeed a key score in T2, it is "ROW_NR", and we can do this:
select t1.col_nr
, t2.row_nr
, t1.sheet_name
, t1.cell
, t1.column_name
, t2.string_val
from t1
left outer join t2 partition by (t2.row_nr)
on t2.col_nr = t1.col_nr
;

Outer join problem - revisited
Hello
I'm starting a new thread since my previous post was an inaccurate representation of the problem I have.
I have data that looks like this.
create table cour_off (offNum number, varchar2 (10) courseId, start_date date);
create table activity (number oid, courseId varchar2 (10));
create table ncr_course (course_oid number, incept_date date, expiry_date date);
insert into cour_off values (1, 'MAT101', to_date (' 15 / 05/2012 ', ' DD/MM/YYYY'));
Insert in activity values (10, 'MAT101');
insert into ncr_course values (10, to_date (' 01 / 05/2012 ', ' DD/MM/YYYY'), to_date (' 10 / 05/2012 ', ' DD/MM/YYYY'));
When I write the query using ANSI notation, the query works fine. 1 form is returned with a NULL value for the incept_date column.
Select activity.courseId, ncr_course.incept_date
of cour_off
Join the activity on cour_off.courseId = activity.courseId
activity.Oid left join ncr_course = ncr_course.course_oid
and cour_off.start_date between ncr_course.incept_date
and ncr_course.expiry_date
where cour_off.offNum = 1
However, when the style non ANSI query as shown below, no records are returned.
Select activity.courseId, ncr_course.incept_date
activity, cour_off, ncr_course
where cour_off.offNum = 1
and cour_off.courseId = activity.courseId
and activity.oid = ncr_course.course_oid (+)
and cour_off.start_date between ncr_course.incept_date and ncr_course.expiry_date
I would like to know how I can resolve the application of style not ANSI so that the 1 record is returned.
Thank you!Well, native Oracle outer join does not allow outside join two tables, to do something like:
select courseId, ncr_course.incept_date from ( select activity.courseId, activity.oid, cour_off.start_date from cour_off, activity where cour_off.offNum = 1 and cour_off.courseId = activity.courseId ), ncr_course where oid = ncr_course.course_oid(+) and start_date between ncr_course.incept_date(+) and ncr_course.expiry_date(+) / COURSEID INCEPT_DA ---------- --------- MAT101 SQL>SY.

Outer join - problem with the name of the table in the select list
Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production
create table (j1)

number of C2);
create table (j2)
number of C1,

insert into values j1 (1, 1000);
insert into values j2 (1, 2);
insert into values j2 (1, 4);
insert into values j2 (1, 8);
commit;
Select c1, j1.c2, j2.c2 of outer join of j1 j2 using (c1); - DOES NOT
Select c1, j1 j2 (c1) using outer join j2.c2. - WORK
Why?
Hello
Interesting question! Oracle goes very far in trying not to trigger an error.
The OUTER keyword (if used; it is always optional) must be preceded by one of the keywords, right or LEFT. Since neither LEFT, RIGHT, or FULL comes before OUTER in queries in your first message, it does not recognize as keyword OUTER and treats him like a table alias for table j1. Since j1 has an alias, the real table name cannot be used in the SELECT clause. This query is executed:
SELECT c1
outer.c2
j2.c2
External J1
Join the HELP of j2 (c1)
;
There is an INTERNAL join. Add to your sample data:
insert into values of j1 (-1, -10);
insert into values of j2 (-2, -20);
to be specified.
Moreover, USING is short for confUSING. I suggest you use IT for all the join conditions. Everyone (unless they you write or read a manual) does.

We use 10.2.0.3 oracle version.Hello
According to the plan of the explain command, > 99% of the cost of the query comes from a single operation - step 27, a comprehensive analysis of the S_INVOICE table.
This probably means that there is no index can be used on DEPT_CD and/or INVC_TYPE_CD.So start by setting SELECT * FROM S_INVOICE WHERE ("T27" T27. "DEPT_CD" =: 2 AND "T27" "." " INVC_TYPE_CD "(=:1)"
BTW the plan shows that the 1 row should be returned, while Oracle actually returns 117 - this means that the optimizer estimates are not very reliable here.

Outer join problem? test code included
Hi all
I have three tables:
Master: It's the program_codes, titles and the active indicator.
Main: Is the 'information sections"on a specific program.
ModeOfS: He intones the sections of main program (abstract e.t.c) full-time part-time (PT) or (FT).
They have all of the effective dates so when he ran during a given year knows whose registration was effective on this year here.
When I run for 2003 I get 4 records which is correct, but when I run for 2002, I have only 2 folders. There is no valid records in the 'ModeOfS' table, but there are three records in the table of the 'hand' that are valid. But missing registration of P1 of the table of the 'hand '.
I have external-joined the main table so I don't see why it doesn't show up. Any help would be great.
Basically, program information may be considered at the level of "ModeOfS" but should not be, it's that his different text. So if it does and it is in the selected year then I want to see it. The limits of two YEARS will always be the same thing that this query will run for one YEARHello

I'm confused. In the sample data you posted, it seems that only 2 tables have dates of application. Did you post erroneous data, at least for the master by mistake?
so when he ran during a given year knows whose registration was effective on this year here.
When I run for 2003 I get 4 records which is correct, but when I run for 2002, I have only 2 folders. There is no valid records in the 'ModeOfS' table, but there are three records in the table of the 'hand' that are valid. But missing registration of P1 of the table of the 'hand '.What are the correct results for 2002? They are:

One of the conditions involving modeofs is an outer join:
... and main.ID = modeOfS.FK_ID(+)but the other is not:
... and nvl(modeofs.TERM_EFF, 9999) = ( select nvl(max(m2.TERM_EFF), 9999) from modeofs m2 where m2.TERM_EFF <= 2003 and m2.SECTION = modeofs.SECTION and m2.MODE_OF_STUDY = modeofs.MODE_OF_STUDY)When you use the old notation to join, if no table of x is always marked with a + sign (as in condition 1 above), then all the conditions involving the x table must have a + sign, otherwise the effect will be an inner join. If you find this confusing, you're not alone. It is one of the reasons why I prefer the ANSI join rating:
with ranked_main as ( select main.* , rank () over ( partition by SECTION order by TERM_EFF desc nulls last ) as MAIN_RANK from main where TERM_EFF <= :target_year or TERM_EFF is null ) , ranked_modeofs AS ( SELECT modeofs.* , rank () over ( partition by SECTION , MODE_OF_STUDY order by TERM_EFF desc nulls last ) as MODEOFS_RANK FROM modeofs WHERE TERM_EFF <= :target_year OR TERM_EFF is null ) select master.* , ranked_main.* , ranked_modeOfS.* from master join ranked_main on ranked_main.PROGRAM_CODE = master.PROGRAM_CODE and ranked_main.MAIN_RANK = 1 left outer join ranked_modeOfS on ranked_modeofs.FK_ID = ranked_main.ID and ranked_modeofs.MODEOFS_RANK = 1 ; -
Problem with XMLTABLE and LEFT OUTER JOIN

outer join and LignesMax problem left
I'm having a problem with the method and an sql join. My left table includes some documents that I want in the list, max 25 per page. These records have some notes are related in another table that is outer joined. When I specify the method in my cfoutput tag it includes my external joined table rows. So I could only go 5 records in my table left and 20 of my attachment table. What I want is 25 records in my table on the left and however the number of records in the table on the other that could be associated with these 25 records. Is this possible?I make two requests and avoid the outer join in this case:

Problem with Outer join and filter
Hello
I join two tables in the source using a left outer join. Outside of the join, I have a filter specified with condition TabA.C1 > TabB.C2.
Now, when ODI generates the query it puts the left outer join on the filter condition as well. So he puts filter as
where
(1 = 1)
And ((TabA.C1 = TabB.C1 (+)) AND)
(TabA.C2 = TabB.C2 (+))
And TabA.C10 > TabB.C14 (+)
How to avoid this problem. I tried this performance on stage as well, always generated query remains the same.
I use the incremental update of the IKM Oracle. My source and target are both on the same PB.
~ ChikkHi Chikk,
If you analyze the data, you'll see it's OK to have the "(+)" to the filter...
Anyway, if you want to drop it, leave it as inner join and put the "(+)" manually to the join object.
This help you?

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.
Concerning
MNMaybe I'm wrong, but I don't think you can do this with a single outer join:
with full_matches as ( select * from master where trx_type is not null) , partial_matches as ( select * from master where trx_type is null) select a.* , coalesce(b.trx_module, c.trx_module) trx_module from transaction a left outer join full_matches b on (a.trx_name = b.trx_name and a.trx_type = b.trx_type) left outer join partial_matches c on (a.trx_name = c.trx_name) ; TRX_NO TRX_NAME TRX_TYPE TRX_MODULE ------ -------------------- -------------------- ------------ 1 aaaa single cont 3 aaaa triple cont1 2 bbbb double cust 4 cccc purpleRe-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.

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 format (LEFT OUTER JOIN)?
THE addresses of Mutiple of return as a single record + current addresses

Hi all
I have to back student addresses home and dormitory under a single registration.
He had to go something like this:
In this format the desired:LAST_NAME FIRST_NAME ADDY_TYPE ADDRESS ZIP Smith John HOME 123 Awesome St 10003 Smith John DORM Oak Quad 10013
You also need to get their last addresses by date.LAST_NAME FIRST_NAME ADDY_TYPE ADDRESS ZIP ADDY_TYPE ADDRESS ZIP Smith John HOME 123 Awesome St 10003 DORM Oak Quad 10013
The database hold records of all students have places moving from dorm to dorm
and some permanent residence ("HOME") has changed as well.
To return only a DORM address and only a HOME address
for each student.
I'm looking at possibly a function BOX to put on a line/record and RANK BY() or DENSE_RANK to determine the last addresses.
Hope I'm making some sense and as always very grateful for any help. Thank you.

The correct code provided by Frank Kulash here:
I need to add a 'NATION' field, located on another table for the addresses of welcome for foreign students.WITH got_rnum AS ( SELECT last_name , first_name , addy_type , address , zip , ROW_NUMBER () OVER ( PARTITION BY last_name , first_name , addy_type ORDER BY addy_date DESC NULLS LAST ) AS rnum FROM table_x -- WHERE ... -- Any filtering goes here ) SELECT last_name , first_name , MIN (CASE WHEN addy_type = 'HOME' THEN address END) AS home_address , MIN (CASE WHEN addy_type = 'HOME' THEN zip END) AS home_zip , MIN (CASE WHEN addy_type = 'DORM' THEN address END) AS dorm_address , MIN (CASE WHEN addy_type = 'DORM' THEN zip END) AS dorm_zip FROM got_rnum WHERE rnum = 1 GROUP BY last_name , first_name ;
I made a LEFT OUTER JOIN with the table of the NATION and the release came out like this:
My desired output would be like this:LAST_NAME FIRST_NAME ADDY_TYPE ADDRESS ZIP NATION ADDY_TYPE ADDRESS ZIP Smith John HOME Rue Henry M1V 4F4 CANADA null null null Smith John null null null null DORM Oak Quad 10013

SSRS for lack of outer join with the Oracle data source
It seems to be a problem with the Oracle driver used in the Reporting SERVICES query designer.
When you use an Oracle data source, if I create an outer join in the graphic designer, it automatically inserts '{OJ' before the join and '} ' after her. This is an incorrect syntax for Oracle and refuses to start. The curly braces and the JO editable in designer text, but if I go back to the graphic designer and immediately to reintegrate them.
Only, this has started to happen a year or two ago - before that it worked, but with the old (+) syntax.
Can it not be healed? It makes things very difficult.

Thanks for posting the CREATE TABLE and INSERT. I know it can be a lot of trouble. You want to get answers that work, not you? Make sure that the statements you post too much work. Test (and, if necessary, attach) your statements before committing. You said code1 be VARCHAR2, but all the instructions insertion have values of 3 characters for code1.
You are on the right track, with an analytical function, but ROW_NUMBER solves this problem. 1 "THAT line" could correspond to the 1st, 2nd, 3rd or any other line 'AE' and vice versa. Try to use the analytical MIN function instead or ROW_NUMBER, like this:
