ORA-01799: a column may not be outer-joined to a subquery
Hi,
How to solve this problem below?
and id2.invoice_line_id*(+)*=(select min(invoice_line_id)
from TW.invoice_detail
where invoice_id=239917
and (bl_amount_currency='USD' AND actual_amount_currency='VND'
OR bl_amount_currency='VND' AND actual_amount_currency='USD')
ERROR at line 150:
ORA-01799: a column may not be outer-joined to a subquery
Since there's an uncertain existence in id2, it needs to be outer-joined to that!
Bst Rgds,
HuaMin
You cant do a outer join on a sub query. Can you describe what are you trying to do?

ORA-01409 NOSORT option may not be used
Hi all,
We've got a range partitioned table, each partition resides in a different tablespace (locally managed) thus :
create tablespace abcblast_hit_test_data1
datafile '/export/data/oracle/HLDDEV05/abcblast_hit_test_data1.dbf'
size 2600m extent management local uniform size 2500m;
create tablespace abcblast_hit_test_data2
datafile '/export/data/oracle/HLDDEV05/abcblast_hit_test_data2.dbf'
size 2600m extent management local uniform size 2500m;
Two large SORTED files of data are sql*loaded into each partition, taking up ONE extent in each partition
I then try to create a non-unique index on the table using NOSORT and get the error ORA-01409 NOSORT option may not be used; rows are not in ascending order
... with the following reasoning :
For non-unique indexes the ROWID is considered part of the index key. This means that two rows that appear to be stored in ascending order may not be. If you create an index NOSORT, and two of the rows in the table have the same index values, but get split across two extents, the data block address of the first block in the second extent can be less than the data block address of the last block in the first extent. If these addresses are not in ascending order, the ROWIDs are not either. Since these ROWIDs are considered part of the index key, the index key is not in ascending order, and the create index NOSORT fails.
BUT the data for each partition DOES reside in one extent :
select partition_name, tablespace_name, extent_id, bytes
from dba_extents
where segment_name = 'ABCBLAST_HIT'
and segment_type = 'TABLE PARTITION';
PARTITION_NAME TABLESPACE_NAME EXTENT_ID BYTES
PART_01 ABCBLAST_HIT_TEST_DATA1 0 2621440000
PART_02 ABCBLAST_HIT_TEST_DATA2 0 2621440000
(Oracle 9.0.1 on Linux)
HELP !!!! Does this mean we can't use NOSORT when building indexes on partitioned tables ?!
(Note : if NOSORT is not used then a sort is performed which we are trying to avoid - final table will contain 1.6 billion rows and will consist of 50 partitions)Hi ,

Page level column may not be referenced
I have a report that has a data link connecting two queries. The child layout will not show up if the link is not equal but the parent layout does. What i need to do is show neither layout if the parent and child are not equal. I tried creating a summary column at the report level and set it to reset at page level. I set it up to get the count of the 'item' in the child layout. Each item has its own page and and if the count = 0 then return(FALSE).
begin
if :cs_1 = 0 then
return(false);
else
return (TRUE);
end if;
end;
I get the following error
REP-1275 Page Level column cs_1 may not be referenced forom format trigger 'R_Item'.
I have tried creating a frame around the entire layout with the same format trigger but it returns the same error.
Any suggestions on how to resolve this probelm?Linking is different from creating one query with a foreign key relation. Its' actually two independent queries.
If you want your kind of behaviour, the easiest way is to create just one query with two groups. Like:
select d.dname, e.ename
from emp e, dept d
where e.deptno = d.deptno
This will never show deptno 40 (if you have the default SCOTT data installed).
Since you already have two queries, you can put the summary column in the parent group, not on report level. -
OBIEE not applying outer join syntax to filters
(Note: I've already thoroughly searched the forums before posting this. Thanks)
My problem is the following:
I'm trying to build a report that is a count from my fact table, grouped by month from my date dimension for a given year, resulting in 12 data points. The problem is that not all months have actual data, but I still need those months to show on the report with a count of zero. Typical simple reporting requirement.
I have already done the obvious and within my business layer made the join between my fact table and my date dimension an outer join on the fact side, just like you'd do if writing the query by hand. And when tested by hand this includes all dates for the year anyway, and when coupled with the appropriate null test on the count measure I'd get my 12 data points with zeros were appropriate.
The problem is that there are additional filters I need to apply on the fact data (there are a couple text-based code values that didn't warrant full tables themselves so are just degenerate dimensions directly on the fact table.)
When these filters are applied at the Answer level, I'm only getting back the months that actually have data, and lose the months where the count should be zero. A check of the session log for the query that was generated shows the problem. While OBI properly generates the outer-join syntax for the join itself between the two tables (my date dim and fact table) it does NOT apply the outer-syntax to the constant-based filter against the fact, effectively negating the outer join.
Actual query from the log (I simply changed the table aliases from the ugly T##### stuff OBI generates to something more readable for posting here):
select D.DT_MONTH_NAME as c1,
D.DT_MONTH_NUM as c2,
I.INC_TYPE as c3,
I.INC_EMP_GROUP as c4,
sum(case when I.INC_KEY is null then 0 else 1 end ) as c5
from DATE_DIM D, INCIDENT_F I
where ( D.DATE_KEY = I.DATE_KEY (+) ) and ( D.DT_YEAR = 2010 and I.INC_EMP_GROUP = 'CONTRACTOR' )
group by D.DT_MONTH_NUM, D.DT_MONTH_NAME, I.INC_TYPE, I.INC_EMP_GROUP
order by c2
You can see that the outer syntax (+) is applied to the join, but not to the filter on I.INC_EMP_GROUP. If I take this query and drop it in something like SQL Developer, it only returns the months with data. If I throw the (+) after I.INC_EMP_GROUP like I'd do if writing this by hand, the desired zero-months results pop back in.
I have already searched the forums and while lots of people seem to have asked this question, the only solutions involve things like trickery in the business layer using dummy fact tables followed by manipulations at the report level etc. Unfortunately I can't rely on these as the system is eventually to be turned over to users who can't be expected to apply various hacks to write reports.
Anyone ever get to the bottom of getting OBI to apply outer join logic in filters as well, when the filtered table is meant to be outer-joined to?
Any comments are appreciated.
JohnI know that this thread is a bit old thought it might be helpful to some one...
The Issue is, when using Degener@teDimen$ion ( this is !nner joned to FACT tables in BMM) and if any of the dimensions {other than theDegener@teDimen$ion (Let us say Dim X) } have an ()uter join to any of the fact tables, and you were doing your analysis using Degener@teDimen$ion, Dim X, Measure value you will face the following issues.
when filtering the analysis on the ()uter join dimension ( Dim X), the IN filter will not work. Reason is that the filter is getting applied to both the Dimension and FACT tables and the values that exist in Dimension Dim X but not in FACT table wont show up.
The above issue can be fixed by changing the join between the fact and Degener@teDimen$ion from inner to outer. I think this is a bug.. because it is supposed to filter the fact table after the entire outer joined result is obtained but not filter the fact table for the Dim X values and do a outer join. I think the BI should be intelligent enough. -
Query slow when exctract column from a left outer join
Hi,
in my 2008 i've a query like this:
select a1, a2,a3
from ....
LEFT OUTER JOIN (select a2,a3....
from my_tab_with_170Milionrecords
if I exclude a2,a3 from principal select the elapsed is about 1
If I include a2,a3 the elapsed is abount 40s
How can solve this?
RegardsI posted an example how re-write it
select a1, a2,a3
from ....
LEFT OUTER JOIN
my_tab_with_170Milionrecords ON ........
Instead of subquery LEFT JOIN user the standard LEFT JOIN..

Can anyone tell me WHY Oracle won't allow sub-queries in outer joins?
Hi,
I've recently been tasked with converting a series of InterBase dbs to Oracle.
Many of the queries in the InterBase dbs use sub-queries in outer joins. Oracle won't countenance this (01799 - a column may not be outer-joined to a subquery).
I can get around it using functions but WHY won't Oracle allow this?
SQL Server allows it, InterBase allows it (I don't know about ANSI SQL) but it seems to be a common enough technique...
I'm just curious (and also a little frustrated!).
Thanks in advance,,,Hi,
>>Oracle treat an empty string as a NULL
Well, you same answer your question. Because it is empty
SGMS@ORACLE10> create table tab (cod number, name varchar2(1));
Table created.
SGMS@ORACLE10> insert into tab values (1,'');
1 row created.
SGMS@ORACLE10> insert into tab values (2,' ');
1 row created.
SGMS@ORACLE10> commit;
SGMS@ORACLE10> select cod,dump(name) from tab;
COD DUMP(NAME)
1 NULL
2 Typ=1 Len=1: 32
SGMS@ORACLE10> select * from tab where name is null;
COD NAME
1Cheers
If you talking about language tools, for example PHP treat empty string <> of NULL values. e.g: functions like is_empty() and is_null()

Outer join problem (ORA-01799)
We have a database design roughly as follows:
- A STAFF table (columns don't matter here).
- Resources have a cost per hour that varies over time, so we have a STAFF_COST table with an effective date and a cost per hour
- A PROJECT table (columns don't matter here).
- Projects can have staff assigned, so we have a PROJECT_STAFF table which has foreign keys to the PROJECT and STAFF table.
- Project staff have a cost per hour, which can vary over time, and be different to the (default) staff costs. So we have a PROJECT_STAFF_COST table which uses the PROJECT_STAFF foreign key, with an effective date and a cost per hour
- Staff work on tasks so we have a TIMESHEET_TASK and TIMESHEET_DAY tables which define a project worked on, task within the project (optional as time can be 'entered against the project', who is recording the time, the hours worked and the day the hours were worked.
So when timesheet information is entered we have three scenario's that we need to cover.
1) The resource is a member of the project and the hours were worked on a day for which we have a project staff cost. That is, the project staff cost table has one or more rows for the staff member assigned to the given project with an effective date before the date the hours were entered against.
2) The resource is a member of the project but the hours were worked on a day for which we do not have a project staff cost. That is, the project staff cost table has one or more entries for the staff member assigned to the given project, but all the effective dates are after the date the hours were entered against.
3) The resource is not a member of the project. That is, the project staff cost table does not have any rows for the staff member. Time was entered 'against the project'.
We need to work out the actual cost of the project. So we need to retrieve every day's timesheet entry, returning the hours assigned and the cost per hour relevant for that day. I have the following query:
select tsh.staff_id, s.full_name, tsd.entry_date, tsd.hours as ProjectHours,
psCOST_INFO.cost_per_hour as ProjectCost
from timesheet_day tsd
inner join timesheet_task tst on tst.timesheet_task_id = tsd.timesheet_task_id
inner join timesheet_header tsh on tst.timesheet_header_id = tsh.timesheet_header_id
inner join staff s on s.staff_id = tsh.staff_id
left join (Select ps.project_id, ps.staff_id, psc.project_staff_id, psc.effective_date, psc.cost_per_hour
from project_staff ps
inner join project_staff_cost psc on ps.project_staff_id = psc.project_staff_id) as psCOST_INFO
on psCOST_INFO.staff_id = tsh.staff_id and psCOST_INFO.project_id = tst.project_id
and psCOST_INFO.effective_date = (select max(ps2.effective_date) from project_staff_cost ps2
where ps2.project_staff_id = psCOST_INFO.project_staff_id
and ps2.effective_date <= tsd.entry_date)
where tst.project_id = 55825
Using the left join covers scenario's 2 and 3 above because I will get null in the cost columns and can then take appropriate action. If I were to use an inner join, then hours in timesheets from scenario's 2 and 3 would be excluded, which is not what we want.
The subselect using the MAX aggregate function is required to get the cost per hour most relevant for the timesheet day. That is, if there are several effective dates for the project staff member before the date in question, we want the most recent one. We can't just use the MAX one, however in case there is an effective date after the particular timesheet date. Sheesh...
This query works fine in SQL Server. It it not allowed in Oracle and returns an ORA-01799 column may not be outer joined to a subquery.
I'm not going to bother to ask why not. I just need a way to do what I want. I've spent days trying to move the code around but I either end up with an inner join (which returns fewer rows than I want) or it just plain don't work.
Can someone help me rework this query to achieve the result I want?
Thanks, AndrewThanks for your reply, Laurent. In my experience trying to cut important corners in explaining a problem only serves to make it more difficult to solve. That pretty much was the smallest reproducable query that demonstrates the complexity of the problem I have. I'm not just trying to get which publishers live in the 'CA' state here...
From what I have just read about rank() it serves the same purpose as max() on a given column, and getting the maximum or top ranked one just doesn't cut it. As I said in my original post that provided all the relevant (and no spurious) information on the problem, it is possible that there are effective dates AFTER the date we are interested in and they have to be excluded.
I have to get the project staff cost row with the latest date that is before the timesheet date. That means I have to reference data in the outer query. Oracle seems to have a problem with that when used in an outer join.
We are currently going down the track of 3 UNION'd statement to cover the 3 scenario's. A single query would be more efficient so if anyone can provide guidance I would appreciate it.
Thanks, Andrew -
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?

Issue with Outer Join (Possible Bug)
Hi,
I am using Toplink 10.3.3 with oracle as db. I noticed that if I use outer joins with collections, then toplink doesnt add (+) sign to the where clause of the collection.
For e.g. for a relationship - Employee has projects, if I do an outer join on projects and also provide a where clause for projects collection, the query doesnt include the (+) sign in it.
Expression expr = builder.anyOfAllowingNone("projects").getAllowingNull("anotherOne-OneMapping").get("attr").equal("Value")
This expr goes in the where clause and TopLink does not generate (+) in the query alongside attr = "Value"
I have tried this from workbench as well as Java. Could anyone please confirm that the above scenario works? May be this is a bug in toplink !
TIA

Need help further tuning view source for outer join
I have been working on tuning views for use in Discoverer for some time, and I have greatly improved upon what was there, but it is still not where I need it to be. There are 2 views the users join together in Discoverer - one for contract lines, and one for contract flexfields. Run as a 1 to 1 join on contract number, performance is great. However, as soon as I have an outer join on flexfields, the performance is awful. We are talking a difference of under a minute to hours and hours. I have to be able to perform an outer join because there can be contracts without flexfields. Can anyone suggest an alternative method to get the data or further tuning?

I am afraid slow performance is a built in feature of this database design, not much you can do in queries.
You could possibly create the views as materialized views and query those instead.
Quote from the linked article
But, how does it perform? Miserably, terribly, horribly. A simple "select
first_name, last_name from person" query is transformed into a 3-table join with
aggregates and all. Further, if the attributes are "NULLABLE" - that is, there
might not be a row in OBJECT_ATTRIBUTES for some attributes, you may have to
outer join instead of just joining which in some cases can remove more optimal
query plans from consideration.
Writing queries might look pretty straightforward, but it's impossible to do in
a performant fashion. -
Full outer join unexpected results
Warning, long message - I've searched the forums and found nothing similar. I've cut out as much as possible. We have been given the following schema to work with:
CREATE TABLE CALLS (
TRUNKIN VARCHAR2 (10),
TRUNKOUT VARCHAR2 (10),
DURATION FLOAT)
Here is some test data:
insert into calls values(null, 'a', 3);
insert into calls values(null, 'a', 2);
insert into calls values('a', null, 1);
insert into calls values(null, 'a', 0);
insert into calls values(null, 'a', 0);
insert into calls values(null, 'a', 7);
insert into calls values(null, null, 0);
This is horribly unnormalized, but basically this table represent phone calls. trunkin and trunkout represent the two ends, and duration is length of a call. While obviously every call has two ends, the nulls above represent ends we don't care about in this example.
The goal is to end up with data that looks like this. In English, we want the in and out summary statistics for each trunk to be summarized into a single row. (Sorry, these are supposed to be columns, but they got wrapped, so I reposted them as rows):
TRUNKIN a
IN_CALLS_ATTEMPTED 1
IN_CALLS_COMPLETED 1
IN_AVERAGE_DURATION 1
TRUNKOUT a
OUT_CALLS_ATTEMPTED 5
OUT_CALLS_COMPLETED 3
OUT_AVERAGE_DURATION 4
Indeed, with the data given above, these are the results returned with the query at the end of this message. However, when I changed the one non-null trunkin value to null, I got very strange results. First, I independently ran the two subqueries. The first of course returns no rows, the second returns 1 with the same out values above; this is exactly what I would expect. However, when I run the full query, I get **5** rows back, each with just the trunkout column set to "a" and **all** other columns set to null. This makes no sense to me. The 5 rows are obviously the 5 rows from the original data set where trunkout = "a", but I'm not full outer joining those; I'm full outer joining the result of the group by, which only has 1 row. But even given that I'm getting 5 rows back, shouldn't all five of those have the remaining out columns filled in with the values above?
Here is the query:
select
from
SELECT
trunkin as trunk,
COUNT(*) AS in_calls_attempted,
SUM
CASE
WHEN duration > 0 THEN 1
ELSE 0
END
) AS in_calls_completed,
SUM(duration)/
SUM
CASE
WHEN duration > 0 THEN 1
ELSE 0
END
) AS in_average_duration
FROM CALLS
WHERE trunkin IS NOT NULL
GROUP BY trunkin
) callsin
full outer join
SELECT
trunkout as trunk,
COUNT(*) AS out_calls_attempted,
SUM
CASE
WHEN duration > 0 THEN 1
ELSE 0
END
) AS out_calls_completed,
SUM(duration)/
SUM
CASE
WHEN duration > 0 THEN 1
ELSE 0
END
) AS out_average_duration
FROM CALLS
WHERE trunkout IS NOT NULL
GROUP BY trunkout
) callsout
on callsin.trunk = callsout.trunk;I am not entirely sure why you are getting the results you are, but I strongly suspect that it is a result of outer joining on null columns. I would write the query as follows to avoid the outer join problem. The CASE statements in the outer query around the average duration calulations avoid the divide by zero error that would occur when some trunk has only in or out calls.
SELECT trunk,SUM(in_calls_attempted) in_calls_attempted,
SUM(in_calls_completed) in_calls_completed,
CASE WHEN SUM(in_calls_completed) <> 0 THEN
SUM(in_duration)/SUM(in_calls_completed)
ELSE 0 END ave_in_duration,
SUM(out_calls_attempted) out_calls_attempted,
SUM(out_calls_completed) out_calls_completed,
CASE WHEN SUM(out_calls_completed) <> 0 THEN
SUM(out_duration)/SUM(out_calls_completed)
ELSE 0 END ave_out_duration
FROM (
SELECT trunkin trunk,COUNT(*) in_calls_attempted,
SUM(CASE WHEN duration > 0 THEN 1 ELSE 0 END) in_calls_completed,
SUM(duration) in_duration,0 out_calls_attempted,
0 out_calls_completed,0 out_duration
FROM calls
GROUP BY trunkin
UNION ALL
SELECT trunkout trunk,0 in_calls_attempted,0 in_calls_completed,
0 in_duration,COUNT(*) out_calls_attempted,
SUM(CASE WHEN duration > 0 THEN 1 ELSE 0 END) out_calls_completed,
SUM(duration) out_duration

SQL for View Definition using outer join
Hello everyone,
I am creating a view using the statement below
SELECT *
FROM table_a A
,table_b B
,table_c C
WHERE A.sg_code = B.sg_code and
B.st_code = 'E' and
A.sg_code = C.sg_code(+) and
C.st_code = 'T'
The structure of the view is as follows
View
sg_code| Name | start_date | end_date |
1 | Test |13-03-2008 | NULL |
Table_a
sg_code,Name
Table_b
sg_code,st_code,actual_date
the view can have a null for the column 'end_date'
This means there will not be a record inserted in the Table_b for end_date=null, there will only be a record for actual_date=start_date
In this scenario when I query the view I am not seeing the newly created record just because there is a condition "C.st_code = 'T'" with the outer join on the sg_code.
When I look into the individual tables I see the records.
Table A
Pg_code,Name
1 Test
Table B
Id pg_code As_of_date
1 1 13-03-2008
How should I modify my view definition so that I can query the view even if there is a null for 'end_date'
Thanks
fmthe last line should be:
C.st_code(+) = 'T'
by failing to include the (+) on that line, you made it NOT an outer join. an outer joined table must be outer joined on every where criteria, including to constants. -
Correlated sub-query/outer join problem
Hi,
I have a problem similar to this one (Outer join with correlated subquery but I'm struggling to find a solution for mine!
The following query works OK unless there is no entry in room_prices, so I need to outer join somehow to that table otherwise it doesn't return any rows.
The main difference between the query in the other thread and mine is that mine has an extra table (bookings b) in the sub-query, which is complicating things a bit.
select b.book_from,
b.book_to,
b.flat_rate,
nvl(c.discount,0),
p.hourly,
p.half_day,
p.daily,
p.discountable,
p.surcharge,
l.evening_start,
nvl(b.full_day,'N')
from booking.bookings b,
booking.customer c,
booking.room_prices p,
booking.rooms r,
booking.location l
where b.id = 9272
and c.id = b.customer
and b.room = p.room
and b.room = r.id
and r.loc = l.id
and p.from_date =
select max(p2.from_date)
from booking.room_prices p2
where p2.room = p.room
and p2.from_date < b.book_from
Could anyone suggest a way to re-write the query so that it is outer joined to room_prices?
Thanks,
HazelThanks for both of your responses.
Unfortunately your suggestion didn't work Dmytro - still no rows are returned.
