Why FULL NATURAL JOIN works?

select * from v$version;
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
Why such constructions are successfully parsed and full/left/right/cross are ignored?
select * from
(select 1 a from dual)
full natural join
(select 2 a from dual);
select * from
(select 1 a from dual)
left natural join
(select 2 a from dual);
select * from
(select 1 a from dual)
right natural join
(select 2 a from dual);
select * from
(select 1 a from dual)
cross natural join
(select 2 a from dual);
The same time if we try to alias tables it gets an error:
select * from
(select 1 a from dual) t1
full natural join
(select 2 a from dual) t2;
ORA-00905: missing keyword
00905. 00000 - "missing keyword"

Try this..

natural full join
(select 2 a from dual) t2;A

A curious "anomoly" with the NATURAL JOIN compared to the JOIN USING

The following query returns what I expect from the HR schema [106 rows]:
select last_name, department_name from employees JOIN departments USING (department_id);
However, when I do the full natural join with this, I only get 32 rows.
select last_name, department_name from employees NATURAL JOIN departments;
Is the full NATURAL JOIN not using DEPARTMENT_ID to join on? But if not what else would it use? I just ran into this and am mostly curious as I do not use the natural join syntax in production but instead prefer the JOIN ON.
Thanks.

Just expanding on user2361373's point a bit, the EMPLOYEES and DEPARTMENTS table both have a DEPARTMENT_ID column and both have a MANAGER_ID column. So the natural join will join on both columns.
This is why the natural join is evil and ought never, ever, ever, ever, ever to be used in real production code. It violates fundamental tenants of building maintainable applications because it creates the potential that adding columns to an existing table will cause existing code to return incorrect results. If you decide that you need to add a CREATE_DATE column to a few tables, for example, to track when a row was inserted, suddenly, all your natural joins may decide that they need to add the CREATE_DATE to the list of columns to join on and your app starts behaving incorrectly. Or your initial DEPARTMENTS table doesn't have a MANAGER_ID column and you decide to add that later on-- all the existing natural joins between EMPLOYEE and DEPARTMENT start returning incorrect results.

Since I joined creative cloud, I have not been able to sync. Why the difference? Worked good during initial trial.
Also I had installed the Mosaic app for ipad before Lightroom mobile came out and I cannot seem to get rid of it. How can I get mosaic out? I have cancelled, I have deleted, I have looked through the files for visible remnants.

The sync count is 60 and static. The total number synced so far is 500+. None have been synced from the ipad except for corrections made there on those already synced.
I have deleted the Mosaic app from all machines and checked the library folder and have contacted the Mosaic tech support and they have discontinued my subscription. I still get mosaic messages on initiating Lightroom and sometimes at closing.
I have not tried to sync fewer yet, but some catalogs that I have tried are smaller numbers. Initially, it did well on good connections. Nothing works on my home connections over satellite.

A simple problem with natural join

i have 2 tables what have columns with distinct's names are referenced.
natural join not works 'cose only foreign key reference this 2 tables.
Have something to make table join in using an specific foreign key??
I'm using oracle9i
Example:
table a( a_cod number, a_name varchar2(20))
table b( b_cod number, b_month_year date, b_salary number)
ALTER TABLE b ADD ( CONSTRAINT b_a_FK FOREIGN KEY (b_cod)
REFERENCES a (a_cod));
select * from a natural join b
where trunc(b_month_year) = trunc(sysdate)

I'm not express me correctly.
We have 2 tables like this:
CREATE TABLE PPTBA001
PPA001_GROUP             NUMBER(3)            NOT NULL,
PPA001_PEOPLECODE        VARCHAR2(20 BYTE)    NOT NULL,
PPA001_NAME              VARCHAR2(60 BYTE)    NOT NULL,
PPA001_DATEOFBIRTHDAY    DATE                 NOT NULL);
CREATE TABLE CLTBA001
CLA001_GROUP            NUMBER(3)             NOT NULL,
CLA001_CLIENTCODE       VARCHAR2(20 BYTE)     NOT NULL,
CLA001_SITUATION        NUMBER(1)             DEFAULT 1);
SELECT * FROM PPTBA001 NATURAL JOIN CLTBA001;
ALTER TABLE CLTBA001 ADD (
CONSTRAINT CLA001_PPAA001_FK1 FOREIGN KEY (CLA001_GROUP, CLA001_CLIENTCODE)
    REFERENCES PPTBA001 (OFA001_GROUP,OFA001_PEOPLECODE));
      the select returns without results. 'cose does not have columns like same name.
Natural join use a columns with same name. I need something use an foreign key.
Why?? Now i have a problem .. i need aggregate one more column in primary key
and i need change all selects that have join with PPTBA001 and put manualy a new column.. if have a other possibility like natural join to using a foreign key to join the selects problems is so more easy to resolve.

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
   FROM calls
   GROUP BY trunkout)

Granting SELECT to user on VIEW with FULL OUTER JOIN fails?

I have a quandary.
Using Oracle 9i, I have created a simple view. When I perform a count on it, rows are returned.
However, when I grant SELECT access to another user, they can't see the VIEW. The VIEW has a FULL OUTER JOIN operation in it.
When I do the same thing using a regular join, it works.
Any ideas why, please?

According to Note:244315.1, it is not possible to make a FULL OUTER JOIN on views owned by another user at the 9i version of Oracle. As above, do not use FULL OUTER JOIN on views owned by another user. Try to use outer join operator (+), and/or UNIONS instead.

Ora-22905:cannot access rows from a non-nested ...(during full outer join)

Greetings Gurus,
I'm getting an ORA-22905 when I try and do a full outer join in the following function. If I include the commented lines in the perstren_diff_recs2 function I get the error. Both halfs of the union query work by themselves. When I union them bam error. Also, when I use the full outer join syntax the Oracle session craps the bed with a end of file communication error. That is why I'm using the simulated full outer join.
My goal was to abstract the XML in my queries. The results from the pipelined function is a delta between what is in the XML document and a relational base table.

Not sure what is wrong with your version. It might have to do with row_number not working on an empty row (outer joined).
How about this alternative?
The approach is a bit different, but it uses only one access to the user_source view.
select s.lineNo, min(s.text1) text1, min(s.text2) text2, decode(upper(min(s.text1)), upper(min(s.text2)), 1, 0) flag

FULL OUTER JOIN In InfoSet

Hi, all
Is it possible to make FULL OUTER JOIN in BI InfoSet?
If no, another question - is it possible to switch base InfoProvider? I have an InfoSet with InfoCube1 and DSO1 which I can outer join. I want to outer join InfoCube1 , not DSO1 that's why I need to switch them in the InfoSet.

Hi,
In BI 7.0 Infoset has given chance to include an Info cube also,maximum you can include 2 info Cubes only in a infoset.
check the below link which helps you in understanding of the join conditions so that you can apply to your scenario.

Using full outer join of subqueries named using with clause

Hi,
I am trying to create a view which is having 2 subqueries vol1 & vol2 with WITH clause. I am joining those 2 subqueries in the main query with FULL OUTER JOIN.
When i compile that view in a tool like pl/sql developer, It has been compiled successfully.
But when i call the view creation script from SQL command prompt, It is throwing error as
from vol1 FULL JOIN vol2 o ON (vol1.ct_reference = vol2.ct_reference and vol1.table_name = vol2.table_name
ERROR at line 29:
ORA-00942: table or view does not exist
Kindly advise whats going wrong.

that's line 29. Maybe you get a better idea if you strip your operation of all the unneccessary elements until it works.
There are some known bugs with subquery factoring (aka with clause) and also with ANSI join syntax, but it is hard to tell what happens here based on your description. But one thing is strange - if it is not a result of formatting (not formatting): I would expect the asterisk beneath the unknown table and not beneath the key word FULL.
P.S.: my editor makes me think it's rather a proportional font thing. Have I already said that I don't like proportional font for SQL code examples?

Union among multiple select queries with full outer join

Hello everyone,
I have 3 different select queries (used FULL Outer Join) which work fine. Now I want to add Union to the results among them and pick the selected columns from each query in the final result. while doing so, I am getting an error as "right parenthesis missing". I am quite sure, it is not the real cause. I guess might be issue with the query structure.

Strange bug with Full Outer Join

Hi guys,
can you please confirm this behaviour on 11gR2? It used to work fine on 10gR1.
Small test case:
create table TEST_OBJECT_METADATA
project_name VARCHAR2(30 CHAR) not null,
object_id     NUMBER not null
create table TEST_OBJECT_INFO
object_id          NUMBER not null,
object_type        VARCHAR2(30) not null
create table TEST_SUPPORTED_OBJECTS
object_type    VARCHAR2(30 CHAR) not null,
enabled        NUMBER(1));
INSERT INTO TEST_OBJECT_METADATA VALUES ('NEW',1);
INSERT INTO TEST_OBJECT_INFO VALUES (1, 'TABLE');
INSERT INTO TEST_SUPPORTED_OBJECTS VALUES ('TABLE',1);
COMMIT;When I execute the following query:
WITH old_project AS
(SELECT oi.object_type,
         oi.object_id
    FROM test_object_metadata om,
         test_object_info     oi
   WHERE om.object_id = oi.object_id
     AND project_name = 'OLD'),
new_project AS
(SELECT oi.object_type,
         oi.object_id
    FROM test_object_metadata om,
         test_object_info     oi
   WHERE om.object_id = oi.object_id
     AND project_name = 'NEW')
SELECT src.object_type,
           t.enabled
FROM (SELECT nvl(o.object_type, n.object_type) object_type
          FROM old_project o
          FULL OUTER JOIN new_project n
            ON o.object_id = n.object_id) src,
       test_supported_objects t
WHERE src.object_type = t.object_type(+);I get the following output:
OBJECT_TYPE     ENABLED
TABLE             So, the outer join to test_supported_objects does not match.
But if I force the FULL OUTER JOIN to run first using rownum:
WITH old_project AS
(SELECT oi.object_type,
         oi.object_id
    FROM test_object_metadata om,
         test_object_info     oi
   WHERE om.object_id = oi.object_id
     AND project_name = 'OLD'),
new_project AS
(SELECT oi.object_type,
         oi.object_id
    FROM test_object_metadata om,
         test_object_info     oi
   WHERE om.object_id = oi.object_id
     AND project_name = 'NEW')
SELECT src.object_type,
           t.enabled
FROM (SELECT nvl(o.object_type, n.object_type) object_type,
                       rownum
          FROM old_project o
          FULL OUTER JOIN new_project n
            ON o.object_id = n.object_id) src,
       test_supported_objects t
WHERE src.object_type = t.object_type(+);I get the expected output:
OBJECT_TYPE     ENABLED
TABLE             1 Thanks in advance.

Without mixing works fine:
WITH old_project AS
(SELECT oi.object_type,
         oi.object_id
    FROM test_object_metadata om,
         test_object_info     oi
   WHERE om.object_id = oi.object_id
     AND project_name = 'OLD'),
new_project AS
(SELECT oi.object_type,
         oi.object_id
    FROM test_object_metadata om,
         test_object_info     oi
   WHERE om.object_id = oi.object_id
     AND project_name = 'NEW')
SELECT src.object_type,
       t.enabled
FROM (SELECT nvl(o.object_type, n.object_type) object_type
          FROM old_project o,
               new_project n
          where o.object_id = n.object_id(+)
          UNION
          SELECT nvl(o.object_type, n.object_type) object_type
          FROM old_project o,
               new_project n
          where o.object_id(+) = n.object_id) src,
       test_supported_objects t
WHERE src.object_type = t.object_type(+);but there shouldn't be any restrictions on mixing them, right?

Now come to required output; which is showing that these plus signed packets (whose master PNO is that) are not as per tab40 vs tab41 something like full outer join between tab40 and tab41. Example :
+ 1112710 is associated with 1112510 in tab40, while in tab41 it is associated with 2996001; so it is difference.
+ 1117001 is associated with 1117014 in tab40, while it is not in tab41.
vice versa;
+ 3332710 is associated with 2996001 in tab41, while it is not in tab40.
I mean, if only plus marked row's PNO's mater packet number is not equal to master PNO(previous non plus marked BNO) in both the table, it should be part of the select query please. Generally this happens, when our packing department gets late delivery of prior master packet, so they just send the small packet with immediate available one (non plus) packet.
Kindly let me; i am clear in my request or i should elaborate more. This may be more complex, because may be bad table/data design, but i need the output by select query please help me.
Regards.

Yes, you have perfectly understood my question... just i added lineno > 1
SELECT bno,
pno,
weight,
lineno
FROM ( SELECT tab40.*, lag (bno) OVER (ORDER BY pno) prev_bno
FROM tab40
ORDER BY pno)
WHERE bno = '+' OR prev_bno = '+' and lineno > 1
ORDER BY lineno
and it worked, because there are no chances that plus marked row will be having lineno <=1

Hi psiplaw
First of all yours query is too complex to understand ,why dont you create view for table c and then use full outer join??
select e.empno,e.ename,d.deptno,d.dname,l.locid
from emp e
full outer join dept d on (e.deptno=d.deptno)
full outer join location l on (d.locid=l.locid);
any how have a look there
