ORA-01417

Folks please solve my problem
i have these tables in from clause, when am executing my code am getting the error
ORA-01417
Error Description:
a table may be outer joined to at most one other table
               TT12_.JE_HEADER_ID(+)=l.JE_HEADER_ID

          and     TT1_.segment1(+)=c.segment1
          and     TT1_.segment2(+)=c.segment2How can we join them
Please help me thanks....

Hi,
Use ANSI join syntax. For example:
FROM           c
JOIN           l     ON    ...
LEFT OUTER JOIN tt12_     ON    TT12_.JE_HEADER_ID     = l.JE_HEADER_ID
                AND   TT12_.segment1          = c.segment1
               AND   TT12_.segment2          = c.segment2
LEFT OUTER JOIN tt_     ON    TT_.JE_HEADER_ID          = l.JE_HEADER_ID
                AND   TT_.segment1          = c.segment1
               AND   TT_.segment2          = c.segment2
LEFT OUTER JOIN tt1_     ON    TT1_.JE_HEADER_ID          = l.JE_HEADER_ID
                AND   TT1_.segment1          = c.segment1
               AND   TT1_.segment2          = c.segment2
...That error only occurs using the older join notation, with +.
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Simplify the proble as much as possible. In this case, you can probably show the problem with just 3 tables (c, l, and any one of the others), and just the columns necessary to join them.
Always say which version of Oracle you're using.

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,
a.HAS_PARAMETER,
a.VALUE_CLASS,
c2.NAME,
a.INDEX_TERMS,
a.DATA_TABLE_ID,
d1.TABLE_NAME,
a.SP_INSERT,
a.SP_UPDATE,
a.SP_GET_BYMRN,
a.SP_GET_BYATTRIBUTE,
a.VALUE_TABLE_ID,
d2.TABLE_NAME,
a.PARAM_TABLE_ID,

WHERE
DOMAIN = p_domain_id AND
b.DOMAIN_ID = a.DOMAIN AND
c1.ID = a.DE_TYPE AND
c2.ID = a.VALUE_CLASS AND
d1.TABLE_ID = a.DATA_TABLE_ID AND -- it works well without the next two lines
d2.TABLE_ID = a.VALUE_TABLE_ID "(+)" AND
d3.TABLE_ID = a.PARAM_TABLE_ID "(+)"
ORDER BY a.NAME;

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

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".

Universe连接Oracle DB遇到ORA-01417 error

Hi,
我用Universe连接Oracle DB, 在universe 中join 了一些表，并且有几张表之间用了left outer join. 然后把Universe Export 到BOE上，用Crystal Report连接这个universe, 在运行的时候得到下面这个error:
"A database error occured. The database error text is ORA-01417: a table may be outer joined to at most one other table. (WIS 10901)"
请教有没有遇到同样问题的，怎么解决的啊？急。。。谢谢！

一张表是不能同时和两张或两张以上的表进行外连接的
你可以这样写
a.id=b.id() and a.name=c.name()
但是你不能这样写
a.id()=b.id and a.name()=c.name
虽然这两种写法的结果是不一样的，但是你的问题就是这个。
你可以去universe看一下，你的left outer join肯定有这样的情况存在。

Translating SQL from MYSQL to ORACLE with more than one outer join.

I have tried in ORACLE with:

MERANT][ODBC Oracle driver][Oracle]ORA-01417: a table may be outer joined to at most one other table
How do I translate the code to ORACLE?

I think that your syntax is wrong. The (+) operator should be on the right hand table column, not the left hand table column if you want all rows on the left hand table column. If this syntax is really what you want, you can create underlying views for each join condiction.

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 (+);

Joining multiple tables in Oracle DB

I have the following tables.
1. AddProject
- projID
- projName
2. AddLab
- labID
- labName
3. ProjLabAssociation
- projID
- labID
4. AddResearchArea
- raID
- raName
5. ProjRAAssociation
- projID
- raID
AddProject is associated with both the tables-AddLab and AddResearchArea
ProjLabAssociation and ProjRAAssociation are association tables which contain the primary keys from corresponding tables. Both the fields in these 2 tables are primary keys.
If AddProject has 3 entries - (Proj1,ProjectA),(Proj2,ProjectB),(Proj3,ProjectC)
AddLab has 2 entries - (Lab1,Bangalore),(Lab2,Chennai)
AddResearchArea has 2 entries - (RA1,Green Computing),(RA2,Cloud Computing)
ProjLabAssociation has 2 entries - (Proj2,Lab1),(Proj3,Lab1)
ProjRAAssociation has 3 entries - (Proj2,RA1),(Proj3,RA1),(Proj3,RA2)
If I am querying by AddLab data for (Lab1,Bangalore), I should be getting the following columns in the result table
Table2ID | Table2Name | Table3ID | Table3Name | Table1ID | Table1Name
Lab1 | Bangalore | RA1 | Green Computing | Proj2 | ProjectB
Lab1 | Bangalore | RA1 | Green Computing | Proj3 | ProjectC
Lab1 | Bangalore | RA2 | Cloud Computing | Proj3 | ProjectC
I have been trying the following commands but I m getting the expected result
1.SELECT * FROM AddLab al, ProjLabAssociation pl, AddProject ap WHERE al.labID = pl.labID(+) and ap.projID = pl.projID(+);An SQLException is thrown saying - java.sql.SQLException: ORA-01417: a table may be outer joined to at most one other table

1. Always tell the community your Oracle version
2. If you want to learn, always show to the community you tries so far
3. Always use tags before and after your code to keep the code formatted on forum side
4. Post in the proper forum according to the question, in yuour case, <a href=PL/SQL & PL/SQL</a> (not Database General)

How to use multiple outer join in ODI

SELECT
Count(*)
FROM
student S,
department D,
course C
WHERE
D.S_Name=S.S_Name
AND D.Dept_Name = C.Dept_Name (+)
and S.C_Name =C.C_Name (+)
And (D.Dept_ID = 1);
I run this query. I got an ORA-01417 error.

In topology change the join option to Ordered ISO
then rewrite your query with ANSI syntax.
SELECT
Count(*)
FROM
student S join department D on D.S_Name=S.S_Name,
student S right outer join course C on S.C_Name =C.C_Name,
department D right outer join course C on S.C_Name =C.C_Name
where
(D.Dept_ID = 1);
First verify the code in sql client befor implementing it in ODI
Thanks,

ANSI SQL 92 SYNTAX OUTER JOIN PERFORMANCE ISSUE

Good Morning
Could anyone explain why the excution time for these two (ment to be identical)
queries run so differently.
oracle syntax execution time 1.06 seconds
select COUNT(*) from
PL_EVENT_VIEW pev,
PL_EVENT_STAFF_VIEW pesv
WHERE pev.EVENT_ID=PESV.EVENT_ID(+)
AND pev.WEEKS=PESV.WEEK_NUM(+)
AND pev.event_id=2520
ansi sql 92 syntax execution time 7.05 seconds
select COUNT(*) from
PL_EVENT_VIEW pev
LEFT JOIN PL_EVENT_STAFF_VIEW pesv
ON (pev.EVENT_ID=PESV.EVENT_ID
AND pev.WEEKS=PESV.WEEK_NUM)
WHERE pev.event_id=2520
Thanks
David Hills

BTW Oracle outer join operator (+) and ANSI SQL OUTER JOIN syntax are NOT equivalent. Consider following:
DROP TABLE T1;
CREATE TABLE T1 (C1 NUMBER);
DROP TABLE T2;
CREATE TABLE T2 (C2 NUMBER);
DROP TABLE T3;
CREATE TABLE T3 (C3 NUMBER);
-- Following SELECT works:
SELECT COUNT(*)
     FROM T1, T2, T3
     WHERE C2 = C1
          AND C3(+) = C1
COUNT(*)
0
-- But:
SELECT COUNT(*)
     FROM T1, T2, T3
     WHERE C2 = C1
          AND C3(+) = C1
          AND C3(+) = C2
AND C3(+) = C1
ERROR at line 4:
ORA-01417: a table may be outer joined to at most one other table
-- However with ANSI syntax:
SELECT COUNT(*)
     FROM T1
     JOIN T2 ON (C2 = C1)
     LEFT JOIN T3 ON (C3 = C1 AND C3 = C2)
COUNT(*)
0

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.

Oute join

How i can apply ANSI standared in i.e LEFT OUTER JOIN because in the query given below it's showing error
SELECT NVL(uiq.question,ucq.question) as question,
iqa.answer as answer,
iqa.seperate_cover as reference_attached,
iqa.attachment_extension as file_extension,
iqa.filename as filename,
addr.address_1 as attachment_address_1,
addr.address_2 as attachment_address_2,
addr.address_3 as attachment_address_3,
addr.address_4 as attachment_address_4,
addr.postcode as attachment_postcode,
cty.description as attachment_country,
iqa.upt_iqa_id as questionanswer.id
FROM upt_iqa_questions_answers iqa,
tpz_add_address addr,
trf_cty_country cty,
ukp_uiq_ins_question uiq,
ukp_ucq_uic_question ucq
WHERE iqa.upt_iap_id = <parameter primary key application>
AND addr.tpz_add_id = iqa.tpz_add_id (+)
AND cty.trf_cty_id = addr.trf_cty_id (+)
AND uiq.ukp_uiq_id = iqa.ukp_uiq_id (+)
AND ucq.ukp_ucq_id = iqa.ukp_ucq_id (+)
ORDER BY iqa.position;

Hello,
I suppose that error message is ORA-01417 : a table may be outer joined to AT MOST ONE other table ?
In this case, it means that you can not outer join iqa to addr, uiq and ucq.
What is the meaning of your tables, and what data would you like to select ?

Need clarification on ANSI Joins

Hi All,
I need some clarification on the ANSI Join which I build to avoid an error when I am trying to execute the same in regular join.
With Regular join I am getting the error ORA-01417: a table may be outer joined to at most one other table.
Regular Join Condition:
select null
FROM
land_event_device_fraud T1, --Update Dealer
land_event_device_upgrade T2, --New Subscriber First Set
syn_intg_event_device_state T3, --Existing Subscriber
land_event_device_upgrade T4 --New Subscriber Second Set
WHERE T1.event_id = T2.event_id(+) AND T1.rate_plan_id = T2.rate_plan_id(+)
AND T1.event_id = T3.event_id(+) AND T1.rate_plan_id = T3.rate_plan_id(+)
AND T4.event_id = T1.event_id(+) AND T4.event_id = T1.rate_plan_id(+)
AND T4.event_id = T3.event_id(+) AND T4.event_id = T3.rate_plan_id(+);
--Getting error ORA-01417.
Replaced the above join with ANSI Join
SELECT NULL
FROM land_event_device_fraud t1
LEFT OUTER JOIN land_event_device_upgrade t2
ON (t1.event_id = t2.event_id AND t1.rate_plan_id = t2.rate_plan_id)
LEFT OUTER JOIN syn_intg_event_device_state t3
ON (t1.event_id = t3.event_id AND t1.rate_plan_id = t3.rate_plan_id),
land_event_device_upgrade t4
LEFT OUTER JOIN land_event_device_fraud t5
ON (t4.event_id = t5.event_id AND t4.rate_plan_id = t5.rate_plan_id)
LEFT OUTER JOIN syn_intg_event_device_state t6
ON (t4.event_id = t6.event_id AND t4.rate_plan_id = t6.rate_plan_id);
I want to know whether the ANSI Join is goig to work fine or it is going to give me any cartesian production information.
Appreciate your help here.
Thanks,
MK.

>

Whenever you have a question, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data. Explain how you get those results from that data.
Always say which version of oracle you're using.
See the forum FAQ {message:id=9360002}
Why does the SELECT clause include only NULL? Is this going to be used as an EXISTS sub-query? If so, why bother to do outer joins, and why do you care if it does a Cartesian product? What is the compete query?
For debugging purposes, you might want to include something that you can see in the SELECT clause.

Lookup from Lookups

Hi all,
I've several reference data tables and one of them is composed from several IDs from the others. To get data from this table i've to make a Lookup to the other tables and with the values from this lookups make a final lookup to this last table.
When i try to do this in a mapping, i've got the error "ORA-01417: a table may be outer joined to at most one other table" (I've no warning or error when composing or deploying the mapping), when i look to the script generated it really makes outer joins to all of the lookup tables i need.
I've tried several other solutions: several joins between each table (that previously represented the lookups); one single join. But nothing works, i always get the same error. (this joins should represent a single table!? No?)
Is this possible to be done? I've worked with several others ETL tools that was easy to do this.
I'm working with:
OWB 9.2
Oracle database 9.2
Thanks,
Vitor

Partial Solution... (not completely satisfied)
If i use an aggregator or a deduplicator before last lookup it works fine, but if i don't want to deduplicate the results!?
Thanks,
Vitor

Forcing joins to be done separately

Is there a way to prevent OWB from combining joins when generating mappings? We have a case were we need to join two tables together and then do an outer join on that result to a third table.
select join.col1, join.col2, c.col3
from (select a.col1, b.col2
from table1 a, table2 b
where a.col1=b.col1) join,
table3 c
where join.col1=c.col1(+)
and join.col2=c.col2(+)
Unforuntately, after creating the mapping using two join operators the SQL generated looks like this ...
select a.col1, b.col2, c.col3
from table1 a, table2 b, table3 c
where a.col1=c.col1(+)
and b.col2=c.col2(+)
As a result, we get this error during execution: "ORA-01417: a table may be outer joined to at most one other table"

Hi,
I had a similar problem with lookups:
Problem with lookups and outer joins
There are two workarounds for your problem that I'm aware of:
1) Insert a sort (or aggregator) between the two joins. This does unfortunately have a performance impact
2) Create a view to resolve one of the two joins. No performance impact, but not very elegant as you have to move "ETL logic" from the model (mapping) down into the database.
Question for development; Is there a reason why separate joins are not always resolved as inline views?
