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?

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

Hi,
Calling function in general is a costly query. And definitely joining with a function 5 times in not an efficient one.
1. You can populate the results for all parameters in a CTE or table variable or temporary table and join (instead of funtion) for different parameters
2. Looks like you want fetch the IDs falling to different indicators for the same @Refdate. You can try something like this
WITH CTE
AS
SELECT
T1.Id ,T1.ColINT_1, T1.ColNVARCHAR_1 collate DATABASE_DEFAULT as ColNVARCHAR_1 ,T1.ColNVARCHAR_2 ,T1.ColSMALLDATETIME_1, T1.ColDECIMAL_1, T1.ColDECIMAL_1, T4.Name
FROM TABLE2 T2
JOIN TABLE3 T3
ON T2.COLFKT3 = T3.Id
AND T3.ReferenceDate = @RefDate
AND T3.State != 'Deleted'
JOIN TABLE4 T4
ON T2.COLFKT4 = T4.Id AND T4.Name=@indicator
JOIN TABLE1 T1
ON T2.COLFKT1=T1.Id
SELECT * FROM CTE WHERE Name = 'ID#1_0#INDICATOR_X' AND Name = 'ID#1_0#INDICATOR_Y' AND Name = 'ID#1_0#INDICATOR_Z' AND Name = 'ID#1_0#INDICATOR_W' AND Name = 'ID#1_0#INDICATOR_A' AND ReferenceDate = @RefDate.
Or you can even simplify more depends on your requirement.

SQVI - join with table T030

Hello!
I am trying to create a query for material accounts with the Quick Viewer (transaction SQVI).
I´ve already added tables MARA, MBEW and T001K, but when i try to add table T030 an error message comes up:
"Table T030 cannot be used in a join" (Message #AQ 501)
Does Anyone know why the Quick Viewer doesn't let me add this table to the join of tables?
Thank you everybody in advance!
cecil

Dear Maria,
Not every table can be join using SQVI, eg:T030,A017,etc.
You can read the notes for this :
1. You cannot read the selected table with SELECT statements (because,
for example, it is a structure without a database table). Therefore,
this table cannot be read within a table join either.
2. The chosen table is a pool or cluster table. These tables may not be
used in a table join.

Issues while joining two tables as the joining column has duplicate values - Please help!

Hi,
I have a table A -which has few columns including a Amount column - I am joining this table A to Table B. The joining column in B has duplicates. So, the number of records are getting more after the joining. As per the requirment when I create a table
after joining the tables and count the salary clumn, there is a difference in the counting. How can I solve this? Can you please help me?

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.
Cheers

and A.key2 = B.key2 (+)
2)
...from A,B
where A.key1||A.key2 = B.key1||B.key2 (+)

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.

Left outer join 3 tables with where-statement

Hi folks,
I hope you can understand (and maybe solve) my problem.
Generally I try to left outer join three tables. The third table is used for a WHERE-statement.
The three table structures are the following:
table 1 (user)
user1 | key
table 2 (detail)
key | ID
table 3 (header)
ID | user2
...and I want to achieve the following structure (as example filled with data):
user | key | ID
|-----|----
xy    | a    | 001
xy    | b    | #
z     | b     | #
The clue ist the usage of the third table. I need the table to set user1 and user2 equal (WHERE) but there are two problems:
1) Obviously I can't left outer join two tables with each other. In this case I already used the 'key' of table 1 to join it with the 'key' of table 2. So I can't left outer join the 'ID' of table 2 with the 'ID' of table 3. Error message that I can only left outer join a table once. Any proposals?
2) I have to include a WHERE to equal user1 with user2. But I am not allowed to use the user2 from table 3 because of the left outer join.
I tried this coding:
SELECT auser1 akey b~id INTO TABLE itab FROM ( table1 AS a
LEFT OUTER JOIN table2 AS b ON akey = bkey )
LEFT OUTER JOIN table3 AS c ON bID = cID )
WHERE auser1 = cuser2.
I would really appreciate your help.

IF you want to join a DB table with an internal table, you need to use the 'FOR ALL ENTRIES' statement.
select dbfields
into table itab2
from dbtab
for all entries in itab
where dbfield1 = itab-field1.
This will get you a second internal table with all the corresponding data for the first selection. You can then join them with a loop through the first table and a read table on the second table (for 1 - 1 relation) or a nested loop statement on both tables (for 1 - N relation). Make itab a hashed table when using read table with key, use a sorted table if you need to loop without key access.

JOIN 2 tables that have same column ?

I need to learn how to join two tables that both have the same column name:
tbl1 - idskey
tbl2 - idskey
the idskey column holds a id_number
When I do the JOIN I would like to make sure that only Distinct records are joined from both tables and that any duplicates are removed in the final join. So if:
Tbl1 has a idskey of: 12345
and
Tbl2 has a idskey of: 12345
In the final JOIN I want to remove one of those duplicates.
I actually need to join 3 tables that have the same linking column names for the join, but if I learn how to do this correctly on 2, that will be a start.
10g for db, thanks!

Hi,
SELECT DISTINCT and GROUP BY are the most common ways to get unique results from non-unique keys. Exactly how you use them depends on exactly what you want to do.
SELECT DISTINCT guarantees that no two rows in the result set, conisdering all columns, will be identical.
GROUP BY produces one row from a set of rows that have a common feature. The values on that row may be a composite of values from various rows in that set (e.g., an average).
Please post a small, specific example. For instance:
"I have two rows in tbl1 ...
and these fhtee rows in tbl2 ...
Notice how there is one row with idskey=12345 in tbl1 but two such rows in tbl2.
How can I get theses results ...
where only one row has idskey=12345?"

Outer join two tables with query search record attached to both tables

When I create a query with two tables that have query search records attached with outer join, PS seems to do a natural join (cartesian). We are on PT8.48.
Is there a workaround for this issue. I do not want to remove query search record on either of the tables.
I am trying to create an Emergency contact report. I am using two tables PS_EMPLOYEES and PS_EMERGENCY_CNTCT. Here is the sql PeopleSoft query generated when I did Left outer Join.
Query SQL:
SELECT A.EMPLID, A.NAME, A.ADDRESS1, A.CITY, B.PRIMARY_CONTACT, B.ADDRESS1, B.CITY, B.STATE, B.POSTAL, B.RELATIONSHIP, A.DEPTID, A.JOBCODE, A.COMPANY, A.EMPL_TYPE
FROM (PS_EMPLOYEES A LEFT OUTER JOIN PS_EMERGENCY_CNTCT B ON A.EMPLID = B.EMPLID ), PS_EMPLMT_SRCH_QRY A1, PS_PERS_SRCH_QRY B1
WHERE A.EMPLID = A1.EMPLID
AND A.EMPL_RCD = A1.EMPL_RCD
AND A1.OPRID = 'SREESR'
AND (B.EMPLID = B1.EMPLID OR B.EMPLID IS NULL )
AND B1.OPRID = 'PS'
Appreciate any help.

I think there are fixes for this issue in later tools releases (Report ID 1544345000). I'm not sure about 8.48, but you might try the workaround documented in
E-QR: Left Outer Joins with Security Records are returning unexpected results [ID 651252.1]
on Oracle Support.

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

Can we join 3 tables with left outer join

hi friends.
 Can any one tell how to join 3 tables using left outer join...i tried by taking some fields of ekko,ekpo,eket, but this not working ... plz give a sample code with some fields.

Hi Uday
Inner joins using 3 tables 
Try this :-
SELECT stpo~stlnr stpo~idnrk mast~matnr mara~mtart stpo~menge
INTO CORRESPONDING FIELDS OF TABLE zmat1 FROM mast
JOIN stpo ON stpo~stlnr = mast~stlnr
JOIN mara ON mara~matnr = mast~matnr
WHERE stpo~stlty = 'M' "AND stpo~idnrk IN s_matnr
AND mast~werks = 1000.
Here s_matnr is a select-options on the selection-screen. 
Or this. 
Code: 
 Select single Vbrk~Bukrs Vbrk~Kunrg Vbrk~Vbeln
 Vbrk~Fkdat Vbrk~Bstnk_Vf Vbrk~Zterm
 Tvzbt~Vtext
 Vbak~Vbeln Vbak~Bstdk
 Likp~Vbeln Likp~lfdat Likp~Lfuhr

 Inner join Vbfa as SalesLnk
 on SalesLnk~vbeln = pu_vbeln and
 SalesLnk~vbtyp_v = c_order
 inner join Vbak on Vbak~Vbeln = SalesLnk~Vbelv
 Inner join Vbfa as DeliveryLnk
 on DeliveryLnk~vbeln = pu_vbeln and
 DeliveryLnk~vbtyp_v = c_Delivery
 inner join Likp on Likp~Vbeln = DeliveryLnk~Vbelv
 where vbrk~vbeln = pu_Vbeln.
This code locates sales, delivery and payment terms info from a billing document number.

How can I crate a view with tables which require "Left outer join"?

Hi guys,
how can I define a view with tables which require "Left outer join"?. In SE11 "View",->tab "Join condition", it seems that it valid only for "Inner Join".
Please give me some hint.
Thanks in advance.
Regards,
Liying

Hi
Inner Join and Outer Join
The data that can be selected with a view depends primarily on whether the view implements an inner join or an outer join.
With an inner join, you only get the records of the cross-product for which there is an entry in all tables used in the view.
With an outer join, records are also selected for which there is no entry in some of the tables used in the view. (ABAP allows left outer join.)
The data that can be selected with a view depends primarily on whether the view implements an inner join or an outer join.

Joining Two Tables with Total Amount

Hi All,
I'm trying to join to tables P02 and P30 on the invoice no fields but getting duplicates. In table P30 we need to sum the payment column per invoice to get the actual payment amount. This then needs to Join to table P02. I have uploaded sample
data on this link and provided an example on how the output should like.
https://app.box.com/s/pu8oa4f3jhrhm0ylshdz2fuo7541vn4z
Thanks
Jag

I figured out why the duplicates appear. I'm attaching another table supplier to fill in the missing propcode when running the query below
SELECT P02.P02_UNIQUE, p30.PROP_CODE, P02.SUPP_ALPHA+P02.SUPP_NUMERIC As SupplierCode, P02.INV_ALPHA+P02.INV_NUMERIC AS InvoiceNo,TotalPayment, Year, Month
FROM P02
CROSS APPLY (
               SELECT PROP_CODE, SUM(TOTAL_AMOUNT) AS TotalPayment, P30.INVOICE_NUMB, DATEPART(year,[CREATED_DATE_SQL]) AS [Year], DATEName(Month,[CREATED_DATE_SQL]) AS [Month]
               FROM dbo.P30
               WHERE P02.INV_ALPHA+P02.INV_NUMERIC = P30.INVOICE_NUMB
               GROUP BY PROP_CODE, COST_CENTRE, DATEPART(year,[CREATED_DATE_SQL]), DATEName(Month,[CREATED_DATE_SQL]), P30.INVOICE_NUMB
               )P30
Where P02.SUPP_ALPHA+P02.SUPP_NUMERIC = '668'
Result below and the last row the prop_code is missing
I have another table supplier which has the suppliercode and propcode so was trying to use the prop_code field from supplier table instead of P30 table to fill in the gap. But when i do that i get duplicates and wrong values.
I have updated the sample data with supplier table.

Outer join With a constant value
