hi
i have this query

Sir ,i am not able to figure out why
SELECT *
FROM fnd_flex_values_vl fvl, xxnp_opn_joblog_001 xoj
WHERE
xoj.rig = fvl.flex_value
returns no value
whereas xoj.rig(+) =fvl.flex_value does return data ---as this returned data ,i would like to add it in my main query then again datatype of rig is char and flex_value is varchar2 .is tht the problem
and again xoj.rig=fvl.flex_value(+) does not return any datai know everyone in the forum is busy but i am just exploring new areas in oracle at my workplace with the tasks i am given ,which is why i post questions here when i am really stuck or ignorant
kindly guide
thanking in advance

OUTER JOIN -- Error: ORA-01417 (a table may be outer joined to at most one

Hi there,
I have a rather simple task: retrieve all the records in a table, for agiven domain p_domain_id (input parameter). The problem is that there are about 6 FKs in the table, and I need the names (strings) corresponding to those FKs (from other tables). Unfortunately, some of the FKs are NULL, so in '=' I loose records. Without the last 2 lines in WHERE clause, I get the correct result. With d2 in place (and without the "(+)" ) I loose 2 records. With the d3 (and also without "(+)"), I do not get any record.
With the "(+)", the code compiles but I get the run time error ORA-01417
NOTE: I put the "+" within parentheses, in order to show it like a text in this editor.
What's an elegant solution to this?
Thanks a lot.
Here's the code:
SELECT
a.DOMAIN,
b.NAME,
a.DE_ID,
a.NAME,
a.PREFERRED_LABEL,
a.TECHNICAL_DEFINITION,
a.PUBLIC_DEFINITION,
a.DE_TYPE,
c1.NAME,

Oracle syntax does not support outer joining to more than one table.

Hi,
Thanks for posting the sample data in such a useful form! I'm sorry, I'm not at a database now, so I can't run it.
What are the correct results you want from that data?
You can outer-join to more than one table using ANSI notation.
Another solution is to do some of the joins in a sub-query. It looks like the problem is with the est table. If you join all the tables except est in a sub-query, then you can join est to that result set in the main query.
If you "want to display the data even if there is no corresponding data in the fac_pos table.", and fac_pos is being called flen, then you have the + signs in the wrong places.
16         AND mtf.EXT_FID (+) = flen.FID
17         AND mtf.EXT_DID (+) = flen.DID means "display data from flen even if there is no match in mtf".

A table may be outer joined to at most one other table

I am trying to use a lookup dim (C) with inputs from 2 different lookup dim (A and B). And I getting the following error:
"a table may be outer joined to at most one other table"
Any suggestion?

This is sql limitation that you can not have queries like
select ...
from a, b, c
where c.x1(+) = a.y
and c.x2(+) = b.z
Probaby you are genearting code similar to this. I will suggest to use Joiner instead of lookup as you have better control over join conditions there. Other option may be to use Transformation function.

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
 into w_vbrk
 from vbrk
 inner join Tvzbt on Tvzbt~Zterm = Vbrk~Zterm and
 Tvzbt~Spras = sy-langu
 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.
or

Here, this one also works fine :
select zfpcd~cadivi zfpcd~proforma zfpcd~factura zfpcd~aniofactura
zfpcd~montousd zfpcd~montoap zfpcd~ebeln zfpcd~inco1
zfpcd~lifnr lfa1~name1 zcdvs~status zfpcd~conint
into it_lista
from zfpcd inner join zcdvs
on zfpcd~ebeln = zcdvs~ebeln
and zfpcd~proforma = zcdvs~proforma
and zfpcd~lifnr = zcdvs~lifnr
inner join lfa1
on zfpcd~lifnr = lfa1~lifnr
where zcdvs~status = '04'.

Multiple tables using left outer join?

Hi, guys:
I have 4 tables: A, B, C; if I want to do the following:
A left outer join B, its result left outer join C.
How can I do that? BTW, I am using DB2.
The following is a sample inner join:
select a.id, b.first, c.last
from A as a, B as b, C as c

How to use left outer join on more than one table (source)

Hi all,
In our project we are converting the Unix shell & SQL scripts into OWB mappings. We are facing problem converting left outer join in OWB. here is one of the example. i have just pasted the FROM and where condition.
FROM ym_scr t1, branch_finmonth t3
LEFT OUTER JOIN item_image t2
ON (t1.branch_no = t2.branch_no
AND t1.item_no = t2.item_no
AND t3.to_date between t2.tran_dt and t2.to_dt
AND t2.to_dt >= '$start_images' ) <<<========= '$start_images' THIS COMES FROM THE UNIX VARAIBLE ,
We converts the same when we are putting it in OWB join Operator
INGRP1.branch_no = INGRP2.branch_no(+)
AND INGRP1.item_no = INGRP2.item_no(+)
AND INGRP3.to_date between t2.tran_dt and t2.to_dt
AND INGRP2.to_dt >= INGRP2.start_images
But as you see in the OWB opreator we can put left join with INGRP1 with INGRP2.
We can not make same join with INGRP3 & INGRP4 , becoz it failed saying "you cannot left outer join on more than one table/source".
so overall this OWB code makes incomplete left outer join as per the above ANSI SQL join in Oracle.
Bcoz of the problem we are getting less number of rows...........
SO please please help me on this
Regards
Ashok

Hi.
I know this topic is here for a while now, but I had the same problem today, searched for help and didn´t find anything.
Later I figured out how to do this.
You just have to put the (+) one time, and the OWB converts in an LEFT OUTER JOIN statement.
For this case, all you have to do is:
( INGRP1.branch_no = INGRP2.branch_no(+) AND INGRP1.item_no = INGRP2.item_no AND INGRP2.to_dt >= INGRP2.start_images )

Double outer join on table

Hi
Let's say I have three tables ORDERS, PRODUCT and CLIENT. I want a query that will give me all PRODUCT and CLIENT combinations and the total sum of orders if it has one. If I try to do this:
select P.NAME, C.NAME, SUM(O.AMOUNT)
from PRODUCT P, CLIENT C, ORDER O
where P.ID = O.PRODUCT_ID(+) and
C.ID = O.CLIENT_ID(+)
I get an error where I cannot double outer join a table.
Any ideas?

But I have complex cases where I much prefer ANSI where I can easily distinguish join predicates from filter predicates. It is a matter of opinion, I know ;-)
But if we then take the original post as a literal specification, that we want all combinations of products and clients and then the sum of order amount if it exists, null otherwise.

Regular Oracle syntax could only do this by creating an inline view of the cartesian join and then outer joining orders with the inline view. Doable, but not as nice (IMHO) as the ANSI method for a case like this ;-)

Outer Join for 2 Tables?

Hi,
i have 3 Tables, one is the "main" table.
Table1
Col1
Col2
Col3
Table2
Col2
Col4
Col5
Table3
Col4
Col6
Now i want all hits from Table 1, all outer join hits from table 2 and the regarding rows from table 3.
The join from Table1 to Table2 is no problem, but how to add table3?
SELECT *
    FROM table1 AS t1
          LEFT OUTER JOIN table2 AS t2
                ON t2col2 = t1col2
   INTO CORRESPONDING FIELDS OF TABLE      result
    WHERE t1~col1 IN so_col1.

Hi,
a right table in an outer join cannot become a part of an inner join or an outer join. So you will have to use some other technique.
meaing table1 connects to table2 with an outer join resulting in all rows table1 and cooresponding if existing from table2, now table2 is the right table it cannot make a join with table3. inner or outer.

Best Practice - Outer Join between Fact and Dim table

Hi Gurus,
Need some advice on the below scenario
I have an OOTB subject area and we have around 50-60 reports based on it. The related subject area Fact and Dim1 table are having inner join.
Now I have a scenario for one report where outer join has to be implemented between Fact and Dim1. Here I am against changing the OOTB subject area join as the outer join will impact the performance of other 50-60 reports.
Can anyone provide any inputs on what is the best way to handle this scenario?
Thanks

Ok. I tried this:
Driving table : Fact, Left outer join -- didnt work.
Driving table: Dimension D left outer join -- didnt work either
In either the case, I see physical query as D left outer Join on Fact F. and omitting the rows.
And then I tried this -
Driving table: Fact, RIght outer join.
Now, this is giving me error:
Sybase][ODBC Driver]Internal Error. [nQSError: 16001] ODBC error state: 00000 code: 30128 message: [Sybase][ODBC Driver]Data overflow. Increase specified column size or buffer size. [nQSError: 16011] ODBC error occurred while executing SQLExtendedFetch to retrieve the results of a SQL statement. (HY000)
I checked all columns, everything matched with database table type and size.
I am pulling Fact.account number, Dimension.account name, Fact.Measures. I am seeing this error each time I pull Fact.Account number.

Maximum number of tables that can be outer joined with one table in a query

Hi All,
Iam new to sql, so can you please let me know What is the maximum number of tables that can be outer joined with one table in a query?
Thanks,

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

How to use outer join on 2 tables with Oracle 8i

Could anyone tell me the Oracle 8i syntax equivalent to :
select user.name, city.adress, contry.name
from user
left outer join city on (user.rCity = city.code)
left outer join country on (user.rCountry = country.code)
I tried following :
select user.name, city.adress, contry.name
from user, city, contry
where user.rCity (+) = city.code
and user.rCountry (+) = country.code
but displayed following error :
ORA-01417: a table may be outer joined to at most one other table
Thank you

Logically I would expect a user to have a city and a country, or not. In that case the outer join should be on the other tables. Making your query:
select user.name, city.adress, country.name
from user, city, country
where user.rCity = city.code (+)
and user.rCountry = country.code (+);

Oracle outer join on multiple tables throws error

Hi ,
We are using ansi joins with outer joins on multiple tables in oracle 9i.
Now these queries have to be used in Oracle8i.
Since Oracle8i does not support ansi sql we are replacing the ansi sql queries with the oracle joins.
On trying the same we found that the following query
select *from tab1 a, tab2 b, tab3 c where a.c1 = b.col1(+) and c.c2 = b.col2 (+)
throws the error
ORA-01417: a table may be outer joined to at most one other table.
Is there a way to simulate this query without using the outer joins on multiple tables?
thanks

Try writing the query in this form:
select * from
(select t1.col1, t1.col2
from schema.table1 t1, schema.table2 t2
where t1.col1 = t2.col1(+)) t4,
schema.table3 t3 where t4.col2 = t3.col2(+)
In the subquery, you will have to list all the columns you want to see, and you will need to provide unique aliases for any columns with duplicate names. I tested this on 9i, and don't have an 8i system to work with, so I hope this helps.

Left outer join on Fact and dimension table.

Hi all, I have a fact F with account number and few measures as columns.
I also have a dimension D with account number, account name columns.
Few account numbers from Fact doesnt exist in Dimension D , but they need to show up in the report though.
How do I left join Fact and Dimension D in RPD?
I have this report where I need to show Account Number, Account name, measures.
If D doesnt have certain account numbers, I need to convert that account number from F as string and show it in the report in account name column.
Can you pls help.

Ok. I tried this:
Driving table : Fact, Left outer join -- didnt work.
Driving table: Dimension D left outer join -- didnt work either
In either the case, I see physical query as D left outer Join on Fact F. and omitting the rows.
And then I tried this -
Driving table: Fact, RIght outer join.
Now, this is giving me error:

Left Outer Joining multiple tables to one source table FAILS with VLD-1511

Hi all,
Is it me, or is OWB unable to handle left outer joining 1 source table to multiple other tables?
I want to load a fact table so I have 1 source table with measures. This table must be outer joined to some dimensions that have their FK in the fact table.
The SQL statement would look like this (and is perfectly valid):
select ...
from input, dim1, dim2
where input.c1 = dim1.c1(+)
and input.c2 = dim2.c2(+);
I put the where clause in the joiner operator and validate, but that gives me message VLD-1511: A table may be outer joined to at most one other table.
Even splitting this up into one outer join per joiner still gives this message.
A search and look around on the forum and on metalink shows there are related issues (like bug 3334035). Seemingly creating a view is the work-around to use.....? (ie downgrading owb to a simple gui tool) }-;
Have other people experienced this problem of not being able to outer join one input table to multiple other tables?
Thanks,
Ed

I have had some feedback from Oracle. It turns out this has to do with 2 issues. Below I have pasted the text that Support gave me:
<---------- START QUOTE ---------->
RESEARCH
=========
Bug 3437036 KEY LOOKUP DOES NOT DETECT ORA-1417 IN VALIDATE/GENERATE STEP
Unpublished Bug 4211684 FORWARD PORT OF BUG 3437036
shows:
Some more development has been completed when this bug is fixed in Paris.
The following are the details:
1. If the join condition contains a full outer join such as
tab1.c (+) = tab2.c (+) and tab2.c (+) = tab3.c
then the new validations implemented for this bug do not apply since
in OWB, full outer join triggers generation of joins in ANSI syntax.
ANSI syntax does not have the original problem the base bug of this
bug reported.
2. If the join condition does not contain any full outer join condition,
then the join is generated in Oracle join syntax, which is subject two
several restrictions. The fix to this bug check two of the restrictions.
3. The first restriction in Oracle syntax is that the outer join operator
"(+)" can only directly be attached to a column name. If you attach it
to an expression, such as the following:
(tab1.c + 1) (+) = tab2.c
Then there will be an ORA-936 error at the time of mapping deployment.
For this case, I have added a validation message VLD-1512 to error out
this situation.
4. The second restriction in Oracle syntax is that a table can only be
outer joined to exactly one other table.
For example, this is an invalid join in Oracle syntax:
tab1.c (+) = tab2.c and tab1.d (+) = tab3.d
because tab1 is left outer joined to tab2 and tab3.
But note that the following is still valid in Oracle syntax:
tab1.c (+) = tab2.c and tab1.d = tab3.d (+)
because tab1 is left outer joined to tab2 and right outer joined to tab3.
So this latter case does not violate the restriction that "same oj" to
more than 1 table is not allowed.
If same oj to more than 1 table is specified in a join condition,
VLD-1511 will be issued, and the map is made invalid.
<---------- END QUOTE ---------->
OWB does a partial validation, ie not all access paths are (can be) checked. A full check is only done by the database itself. So some scenarios (like checking whether multiple tables are outer joined the correct way) are not checked, and in this case are flagged with an error (even though it is actually a correct scenario).
Seemingly this was not flagged with an error in earlier versions of OWB, so beware, OWB behaviour may change when upgrading...
Alternative solutions are (1) using key lookups, (2) using a view with all outer joins in there, (3) using intermediate result tables between the joins.
Hope this info helps some people prevent spending too much time on a false error message,
Ed
