Outer join with BETWEEN clause

Hi All,
I have 2 tables (A and B) which i need to join. I need all records from table A and matching records from the table B. below is the structure.
TABLE A (total rows = 10)
ROW_WID
GL_DATE
LOCATION_CODE
TABLE B (total = 7)
ROW_WID
START_DATE
END_DATE
LOCATION_CODE
Initially, we were asked to join based on location_code. In the table B, some of the LOCATION_CODE are missing, which is present in table A.
We wrote below query
SELECT A.*, B.START_DATE, B.END_DATE
FROM A, B
WHERE A.LOCATION_CODE = B.LOCATION_CODE (+)
This gives 10 records, where 3 records have START_DATE and END_DATE NULL. because of outer join
It gave all records from the A table. It worked fine. Now i need to add one more condition where A.GL_DATE between B.START_DATE and B.END_DATE
If i write this
SELECT A.*, B.START_DATE, B.END_DATE
FROM A, B
WHERE A.LOCATION_CODE = B.LOCATION_CODE (+)
AND A.GL_DATE BETWEEN B.START_DATE and B.END_DATE
This gives me only 7 records. IS IT POSSIBLE TO ADD OUTER JOIN with BETWEEN clause.

Hi All,
I'm in a similar situation,
I have a complex query, everything is working fine, except this part (I will simplify everything, removing other stuffs because I need help only on the following condition)
SELECT *
from transaction t, card c
where c.card_id = t.card_id (+)
and t.trn_date between to_date ('01/01/2012','dd/mm/yy') and ('01/01/2013,'dd/mm/yy')
How could i OUTER JOIN the between condition?
I tried with
and t.trn_date between to_date ('01/01/2012','dd/mm/yy') (+) and ('01/01/2013','dd/mm/yy') (+)
but returns a "missing expression" error.
Surely I'm missing some stupid thing about it, could you help me on this? (probably because I'm talking about parameters and I cannot put the outer join on a value)
How can I rewrite the condition in order to satisfy what I'm trying to accomplish?
Thanks in Advance,
Alex

Outer Join with Where Clause in LTS

HI all,
I have a requirement like this in ANSI SQL:
select p1.product_id, p1.product_name, p2.product_group
from product p1 left outer join product_group p2 on p1.product_id = p2.product_id
and p2.product_group = 'NEW'
In Regular SQL:
select p1.product_id, p1.product_name, p2.product_group
from product p1, product_group p2
WHERE p1.product_id *= p2.product_id and p2.product_group = 'NEW'
In OBIEE, I am using a left outer join between these two in Logical table Source, and also, Gave
p2.product_group = 'NEW' in WHERE clause of LTS.
This doesn't seem to solve purpose.
Do you have any idea how to convert WHERE clause in physical query that OBIEE is generating to something like
product p1 left outer join product_group p2 on p1.product_id = p2.product_id AND p2.product_group = 'NEW'
I am using Version 10.1.3.4.1
Creating an Opaque view would be my last option though.

Hello
I have read your post and the responses as well. and I understand that you have issues with the Outer Join with where Clause in LTS.
Try this solution which worked for me (using your example ) -
1. In the Physical Layer created a Complex join between PRODUCT and PRODUCT_GROUP tables and use this join relationship :
PRODUCT.PROD_ID = PRODUCT_GROUP.PROD_ID AND PRODUCT_GROUP.GROUP_NAME = 'MECHANICAL'
2. In the General Tab of PRODUCT table LTS add PRODUCT_GROUP table and select Join Type as Left Outer Join.
3. Check Consistency and make sure there are no errors .
when you run a request you should see the following query generated -
select distinct T26908.PROD_ID as c1,
     T26908.PROD_NAME as c2,
     T26912.GROUP_NAME as c3
from
     PRODUCT T26908 left outer join PRODUCT_GROUP T26912 On T26908.PROD_ID = T26912.PROD_ID and T26912.GROUP_NAME = 'MECHANICAL'
order by c1, c2, c3
Hope this works for you. If it does please mark this response as 'Correct' .
Good Luck.

Outer join with where clause in the universe

Hi,
I have two tables such as:
Patient Table (P)                          Territory Table (T)
P. Alignment ID --------------------------   T.Alignment ID
P. Patient ID                                    T. Region
Two tables are joined on alignment ID, follow is how the data looks like
When i run the query only on Patient Table i get the following
e.g.
Select P.Patient ID, P.Alignment ID
from Patient Table (P)
Where P.Data_date=P.Latest data date
----Note that there is a Where clause here always & i get the following result
P.Patient ID         P.Alignment ID
    1                            1a
    2                             2a
    3                            3a
    4                            Null
    5                            Null
Now when i join two tables on Alignment ID
e.g.
Select P.Patient ID, P.Alignment ID,T.Region
from Patient Table (P)
LEFT OUTER JOIN Territory Table (T)
ON P. Alignment ID = T.Alignment ID
Where P.Data_date=P.Latest data date
AND T.Data_date=T.Latest data date
Following is the result:
P.Patient ID         P.Alignment ID
    1                            1a
    2                            2a
    3                            3a
Even with the left outer join it is not brining in the Null values , it seems that because of the WHERE clause the LEFT OUTER is working as a INNER join.
How can i get the Null rows with my join to the territory table ?
Please Advise,
Thanks,
Sheikh

its not letting me atatched the excel extract but the data is simple as i shown above e.g.
Patient Table (P)                          Territory Table (T)
P. Alignment ID --------------------------   T.Alignment ID
P. Patient ID                                    T. Region
Two tables are joined on alignment ID, follow is how the data looks like
When i run the query only on Patient Table i get the following
e.g.
Select P.Patient ID, P.Alignment ID
from Patient Table (P)
Where P.Data_date='01-OCT-2014'
----Note that there is a Where clause here always & i get the following result
P.Patient ID         P.Alignment ID
    1                            1a
    2                             2a
    3                            3a
    4                            Null
    5                            Null
Now when i join two tables on Alignment ID
e.g.
Select P.Patient ID, P.Alignment ID,T.Region
from Patient Table (P)
LEFT OUTER JOIN Territory Table (T)
ON P. Alignment ID = T.Alignment ID
Where P.Data_date='01-OCT-2014'
AND T.Data_date='01-OCT-2014'
Following is the result:
P.Patient ID         P.Alignment ID
    1                            1a
    2                            2a
    3                            3a
Now the whole issue is that the condition in the WHERE clause is making it act like a inner join and iw ant the NULL rows to appear

Problem with outer join with filter on join column

Hi,
In physical layer I have one dimension and two facts, and there's an outer join between the facts.
dim_DATE ,
fact_1 ,
fact_2
Joins:
dim_DATE inner join fact_1 on dim_DATE.DATE = fact_1.DATE
fact_1 left outer join fact_2 on fact_1.DATE = fact_2.DATE and fact_1.SOME_ID = fact_2.SOME_ID
When I run a report with a date as a filter, OBIEE executes "optimized" physical SQL:
select fact1.X, fact2.Y
from
Fact_1 left outer join on fact_1.DATE = fact_2.DATE and fact_1.SOME_ID = fact_2.SOME_ID
where Fact_1.DATE = TO_DATE('2009-05-28' , 'YYYY-MM-DD' )
and Fact_2.DATE = TO_DATE('2009-05-28' , 'YYYY-MM-DD')
The filter on Fact_2.DATE effectively replaces outer join with inner.
Is there a way to disable this "optimization", which is actually very good for inner joins, but doesn't allow outer joins?
Thanks in advance,
Alex
Edited by: AM_1 on Aug 11, 2009 8:20 AM

If you want to perform a Fact-based partitioning with OBIEE (two fact with the same dimension), you have to :
* create in your physical layer for each fact table the joins with the dimension
* create in the Business Model layer ONE star schema with ONE logical fact table containing the columns of your two physical fact table
In this way when you choose minimal one column of your fact1 and one column of your fact2, OBIEE will perform two query against each fact table/dimension, join them with an OUTER JOIN and your problem will disappear.

Outer Join with the query

I have written the below query, our requirement is, Some employees have "Transport Allowance" but not "Project Allowance". For this, I tried to use OUTER JOIN with this query. But this query takes long time and failed.

How to achieve an outer join with existsNode() function

I have a requirement to do an outer join with existsNode() function in my where clause. At present my where clause for join is like below
WHERE A.SOME_ID= “XYZ”
AND existsNode (B.SOMEXML_FEILD , …. ) = 1
AND existsNode (C.SOMEOTHERXML_FEILD , …. ) = 1
In this case if the existsNode fails on B or C, I still want data from A to be selected. How to rewrite this query to achieve that? I kinda want to achieve an outer join

There is no limit to the number of tables you can outer join as long as you join them correctly.

Outer Join with an 'OR'

I have a very complicated query to construct that requires the use of 'AND', 'OR', and Outer Joins. Oracle's 9i documentation says you can't use an outer join with an 'OR'.
Can you suggest how I may return the correct records under the following conditions. There are 3 tables to join. Table A, Table B, and Table C. Tables A & B join with an = to common fields. The problem is with Table C.
The way the application was designed, it has to track a parent and child relationship. As such, the field to relate may exist in 1 of 2 fields. Let's see if I can draw it out for you.
Table A - Record 1
(ID = 1)
Table B - Record 1
(ID =1 [this relates to Table A.ID]
PID = 12345
CID = 67899
Site = A)
Table C - Record 1
(PID = 12345 [this relates to Table B.PID]
CID = 67899
Site = A)
Table C - Record 2
(PID = 67899 [This relates to Table B.CID]
CID = 12345
Site = A)
Now, I need to relate Table A to Table B where A.ID = B.ID AND
((B.PID = C.PID AND B.CID = C.CID)
OR
(B.CID = C.PID AND B.PID = C.CID))
AND
B.SITE = C.SITE
There may or may NOT be related records in Table C. That's the problem. This is where I need the outer join to get the all the records of the 1st two joins and only those that apply from the last join.
Your help will be greatly appreciated.

I'd create two queries, a join from b to c in each of those manners and then UNION ALL the results together.
drop table junk_a;
create table junk_a (
id number );
drop table junk_b;
create table junk_b (
id number,
pid number,
cid number,
site varchar2(80) );
drop table junk_c;
create table junk_c (
pid number,
cid number,
site varchar2(80) );
insert into junk_a values (1);
insert into junk_b values (1, 12345, 67899, 'A');
insert into junk_c values (12345, 67899, 'A');

Outer join with effective date in peoplesoft query

Hi,
I'm trying to join two tables using outer join. Both tables are effective dated:
Dept_Tbl: dept_id, status, effdt
Tips_Tbl: dept_id, tips_id, effdt
Not all records in Dept_Tbl are in Tips_Tbl. I need to get all active depts and their most recent tips_id if they have one.
select a.dept_id, b.tips_id
from dept_tbl a, tips_tbl b
where a.status = 'Active'
and a.effdt =
(select max(a_ed.effdt) from dept_tbl a_ed
where a.dept_id = a_ed.dept_id
and a_ed.effdt <= SYSDATE)
and b.dept_id(+) = a.dept_id
and b.effdt =
(select max(b_ed.effdt) from tips_tbl b_ed
where b.dept_id = b_ed.dept_id
and b.tips_id = b_ed.tips_id
and b_ed.effdt <= SYSDATE)
The query only returns records that are in both tables.
Is there a way for outer join to work with effective dates?
Thanks in advance,
Reg

Here is an example of one solution. Note the use of NVL on both sides of the equal sign since both sides could be NULL in the case of the outer join
with dept_tbl as (select 1 dept_id, SYSDATE effdt FROM DUAL),
     tips_tbl as (select 1 dept_id, NULL effdt FROM DUAL)
select a.effdt
from dept_tbl a,
       tips_tbl b
where b.dept_id(+) = a.dept_id
   and NVL(b.effdt, SYSDATE) = NVL((select max(b_ed.effdt)
                                      from tips_tbl b_ed
                                     where b.dept_id = b_ed.dept_id
                                       and b_ed.effdt <= SYSDATE), SYSDATE);

Join columns of outer join with table have no uniqueness cons

Hi! I'm getting noizy error in alert log from time to time:
Join columns of outer join with table <table_name> have no uniqueness constraints
I've collected all the queries (v$sql, all_source) with montioned table, but non of them produces that error if executed.
Any hints how to reproduce this error or where else to search that buggy sql join?
Edited by: user545083 on 25.10.2010 6:21

Hi
I think this error is output via an materialized view refresh - check for mviews against the given table which fulfil the issue given in the error text.
Thanks

Outer join: difference between two queries

Below two queries that should give the same results in my opinion. I want all the records from u_protocol and only the value of pval.u_protocol_variable_value if present.
Why does the outer join in query2 doesn't work like in query1?
Query1:
select p.u_protocol_id, i.u_protocol_variable_value
from lims_sys.u_protocol p,
   select pval.u_protocol_id, pval.u_protocol_variable_value
   from lims_sys.u_protocol_variable pvar, lims_sys.u_protocol_value_user pval
   where pvar.u_protocol_variable_id = pval.u_protocol_variable_id
   and pvar.name = 'VALUE_Protocol_Group'
) i
where p.u_protocol_id = i.u_protocol_id (+)
Query2:
select prt.u_protocol_id, pval.u_protocol_variable_value
from lims_sys.u_protocol prt, lims_sys.u_protocol_variable pvar, lims_sys.u_protocol_value_user pval
where pvar.u_protocol_variable_id = pval.u_protocol_variable_id
and prt.u_protocol_id = pval.u_protocol_id (+)
and pvar.name = 'VALUE_Protocol_Group'

In the first query restriction pvar.name = 'VALUE_Protocol_Group' is limited to your inline view. So when you do a outer join with the u_protocol table you will get the number of records which are there in the u_protocol table.
But when you gave the restriction pvar.name = 'VALUE_Protocol_Group' outside the inline view, the restriction was based on the resultset as a whole. So you will get only those records which have pvar.name = 'VALUE_Protocol_Group' condition satisfied.
Hope the following illustration helps:

Following Query is resemblence to your first query

         7 G
         8 H
         9 I
        10 J
10 rows selected.Here TEST_TAB_B Table is restricted with a condition which will restrict the inline view to have only one record. So when you outer join the inline view you will get output as shown above.
The following query resembles to your second query.
SQL> SELECT a1.col_1, a1.col_2, a2.col_3, a2.col_4 FROM TEST_TAB a1,
2 TEST_TAB_B a2
3 where a1.col_1 = a2.col_3(+)
4 and a2.col_4 = 'A'
5 order by a1.col_1
6 /
     COL_1 COL_      COL_3 COL_
         1 A             1 A
1 row selected.
SQL> DROP TABLE TEST_TAB_B
2 /
Table dropped.
SQL> DROP TABLE TEST_TAB
2 /
Table dropped.
SQL> To understand this lets break up the resultset.
Resultset brought by join condition would be something like :
    COL_1 COL_      COL_3 COL_
         1 A             1 A
         2 B
         3 C
         4 D
         5 E             5 E
         6 F             6 F
         7 G             7 G
         8 H             8 H
         9 I             9 I
        10 J            10 JAgreed?
Now when you add the extra condition a2.col_4 = 'A' thecondition will act upon the above resultset there by restricting the records to:
     COL_1 COL_      COL_3 COL_
         1 A             1 AHope this helps.

Case statement resulting into Left outer join with other tables

Hi All ,
I am facing a stuation where a Case statement on one of the logical columns in Answers is resulting into a left outer join with a table in the query.
If we remove the case stmt, the table is not being acessed.
The case stmt is a simple one and no other logical column is being accessed in the case stmt.
Please advice .
Thanks.

Hi Sai,
No ..we dont have any left outer join ...its just that I am selecting measure from F1 which has a confimred dimension D1 with F2.Now when I dont have case stmt on measure from F1(Case stmt is something like : CASE WHEN "- P table"."P Column" = 'Y' THEN 'Right' ELSE 'Wrong' END), then it doesnt query F2.
However as soon as I introduce the case stmt ,the query creates a left outer join with F2.
Thanks.

Inner join Vs Outer join with ABAP code...?

Inner join Vs Outer join with ABAP code...?

Inner Join means, it will not select that recor at all, unless there is a matching entry in the second table.
suppose table VBAK INNER join table VBAP on VBAKVBELN = VBAPVBELN.
In this case, if there are no entries in VBAP, the header entry also will not show up.
But in case of OUTER JOIN, even if there is no items, it will show the header entry(VBAK) with blank columns for fields from item table.(VBAP)
here is one sample for inner join.
SELECT   A~EBELN
           A~EKORG
           A~EKGRP
           A~BSART
           A~LPONR
           A~LOEKZ
           A~LIFNR
           A~RESWK
           B~AEDAT
           B~WERKS
           B~MATNR
           B~MENGE

           FROM EKKO AS A INNER JOIN EKPO AS B
           ON

Outer join with a WHERE clause

hi, this is driving me round the bend. I thought i was ok with sql joins and the like, but im really struggling on this one.
I have table A (for argument sake tblRegion) and table B (tblBranch). if i want to return everything i would do something like this:-
select * from tblRegion join tblBranch on tblRegion.id=tblBranch.reg_id.
If i wanted to return all regions even if they do have a branch associated i would do something like this:-
select * from tblRegion left outer join tblBranch on tblRegion.id=tblBranch.reg_id.
My problem is, I want to return all Regions and use a WHERE clause to narrow the Branch results.
I've tried something like this but it doesnt work
select * from tblRegion left outer join tblBranch on tblRegion.id=tblBranch.reg_id WHERE branch.name like 'LONDON%'
Is there anyway i can return all branches where name is like LONDON, and STILL return all Region if there is no data for that Region?
Do i need to use a nested select statement maybe?
Many thanks in anticipation somebody will save me from my current madness. David

Check this link. It explains the most common problem/coding error while using outer join.
http://www.orafaq.com/node/855
Effectively in your case you need the following condition in your where clause
where nvl(branch.name,'LONDON') like 'LONDON%'
Hope that helps.
