Repalcing UNIOn with full outer Join

I have a query wihch looks like ,
select colA,colB ,colC, coldD from A,B,C,D
where (some join conditions)
union
select colA,colB ,colC, NULL from A,B,C
where (some join conditions)
This query is posing us serious performance issues and we want to tune the query.
SO to remove the UNION operator we want to use FULL JOIN.
Can you please let us know how to frame the full outer join in the above query,so that the result set intact.
Thanks Much

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.

Query with FULL OUTER JOIN , help pleaseeeeeeeeeeee...

Hi everyone,
I'm trying to write a query for a report in Oracle SQL, but i just can't figure out how to do it.
I'm using Oracle 10g release 1.0 database and i execute my queris in SQL* PLUS ( eventually i'm gonna use them in Oracle Report Builder ) .
here's what i have:
i have four tables that are used for our inventory application. lets call them INCOMMING , INCOMMING_ITEMS , OUTGOING , OUTGOING_ITEMS.
as you may have guessed , INCOMMING_ITEMS is the detail table for INCOMMING ( joined by IID column) and also OUTGOING_ITEMS is the detail table for OUTGOING ( joined by OID column ).
here is the structure of them :
INCOMMING
IID varchar2
CDATE date
INCOMMING_ITEM
IID varchar2
PART_NO number
QTY number
OUTGOING
OID varchar2
CDATE date
OUTGOING_ITEM
OID varchar2
PART_NO number
QTY number
now , the query i want, should return part_no , cdate , sum of OUTGOING qty , sum of INCOMMING qty .
the result of the query should be sth like this :
part_no     cdate     O_qty     I_qty
100     01/05/06     10     0
100     01/05/07     20     60
200     01/06/02     0     50
300     01/06/02     30     40
this means that for some dates and for some parts, i may not have INCOMMING or OUTGOING data, but if at least one of the 2 last columns has a non-zero data, i should show the row ( like the first and third rows of my example result), and if both have data for the same PART_NO and the same CDATE, both should be showed in the same row. ( like the second row in my example result)
i tried so much and came up with several huge and also time consuming queries, but then i read abt FULL OUTER JOIN somewhere and tried using that. here is what i came up with :
SELECT
PART_NO , CDATE , sum(II.QTY) I_QTY , SUM (OI.QTY) O_QTY
FROM
     (OUTGOING O INNER JOIN OUTGOING_ITEM OI USING ( OID ) )
FULL OUTER JOIN
     (INCOMMING I INNER JOIN INCOMMING_ITEM II USING ( IID ) )
ON ( I.CDATE = O.CDATE AND II.PART_NO = OI.PART_NO)
WHERE
I.CDATE = :PARAMETER1
AND O.CDATE = :PARAMETER1
GROUP BY
PART_NO , CDATE
this query is short and fast , but the results r not what i expected. i mean, although i have used FULL OUTER JOIN in the query , but the results i get r sth like this :
part_no     cdate     O_qty     I_qty
100     01/05/07     20     60
300     01/06/02     30     40
which means only the rows that has both values are returned.
any change i make to this query would make the SQL* PLUS hang , like when i use the cartesian product of two large tables, so i guess my changes wheren't in the right direction.
i think its possible to write this query using FULL OUTER JOIN syntax, but i just can't find it.
Can anybody pleaseeeeeeeeeeeee help me?
thanx in advance,
Maryam.

Note: I wrote this on the fly -- hope there is no syntax errors, otherwise forgive me -- but you get the idea..

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.

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?

Hi,
The query I posted yesterday is a little more complicated than it needs to be.
Since my_tab2.workstation is unique, there's no reason to do a separate sub-query like mt1; we can join my_tab1 to my_tab2 and get the SUM all in one sub-query.
SELECT       foj.workstation
,       foj.sum_my_value
,       foj.wkstn_name
,       mt3.my_nbr1
,       mt3.my_nbr2
FROM       (     -- Begin in-line view foj for full outer join
          SELECT        mt1.workstation
          ,        SUM (mt1.my_value)     AS sum_my_value
          ,        mt2.wkstn_name
          FROM        my_tab1   mt1
          ,        my_tab2   mt2
          WHERE        mt1.workstation     = mt2.workstation (+)
          GROUP BY   mt1.workstation
          ,        mt2.wkstn_name
                UNION ALL
          SELECT      workstation
          ,      0      AS sum_my_value
          ,      wkstn_name
          FROM      my_tab2
          WHERE      workstation     NOT IN (     -- Begin NOT IN sub-query
                                           SELECT      workstation
                                   FROM      my_tab1
                                   WHERE      workstation     IS NOT NULL
                                 )     -- End NOT IN sub-query
       ) foj     -- End in-line view foj for full outer join
,       my_tab3 mt3
ORDER BY foj.wkstn_name
,       foj.workstation
,       mt3.my_nbr1
,       mt3.my_nbr2
;Thanks for posting the CREATE TABLE and INSERT statements, as well as the very clear desired results!

... So, what I want is a full outer join of t1 and t2 on workstation, and a cross-join of that with t3. That it, exactly!
The tricky part is how and when to get SUM (my_value). You might approach this by figuring out exactly what my_tab3 has to be cross-joined to; that is, exactly what should the result set of the full outer join between my_tab1 and my_tab2 look like. To do that, take your desired results, remove the columns that do not come from the full outer join, and remove the duplicate rows. You'll get:
workstation     sum(my_value)     wkstn_name
ABCD          30          WKSTN 1
A123          35          WKSTN 2
B456          0          WKSTN 3
????          5          NULL          So the core of the problem is how to get these results from my_tab1 and my_tab2, which is done in sub-query foj above.
I tried to use self-documenting names in my code. I hope you can understand it.
I could spend hours explaining different parts of this query in more detail, but I'm sure I'd waste some of that time explaining things you already understand. If you want an explanation of somthing(s) specific, let me know.

Are Multiproviders union or Full outer Joins of their InfoProviders?

I was modeling an heterogeneous Multiprovider and thinking about the expected result set of my query. Looking at SAP note 379736, we can see that's really doing a full outer join sql operation, not an Union. Am I thinking right about that?

Yes you're right, this is not really an union nor a full outer join but sometimes simplifying things can make them more understandable...
UNION=
Combines the results of two or more queries into a single result set that includes all the rows that belong to all queries in the union. The UNION operation is different from using joins that combine columns from two tables.
The following are basic rules for combining the result sets of two queries by using UNION:
The number and the order of the columns must be the same in all queries.
The data types must be compatible.
FULL OUTER JOIN=
Specifies that a row from either the left or right table that does not meet the join condition is included in the result set, and output columns that correspond to the other table are set to NULL. This is in addition to all rows typically returned by the INNER JOIN.

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?

OWB does not allow full outer join

I got following error (twice) while validating my mapping: "VLD-1506: Invalid Expression: Mixing full and partial outer joins in one mapping is not supported".
I have following join conditions in my mapping:
1) INGRP1.DISTRICT_ID = INGRP2.DISTRICT_ID And INGRP1.CHARGE_PERIOD_ID = INGRP2.CHARGE_PERIOD_ID And INGRP1.UTL_ID = INGRP2.UTL_ID
2) The same
3) INGRP1.CHARGE_PERIOD_ID (+) = INGRP2.CHARGE_PERIOD_ID (+) And
INGRP1.DISTRICT_ID (+) = INGRP2.DISTRICT_ID (+) And
INGRP1.PROVIDER# (+) = INGRP2.PROVIDER# (+)
I suppose there is not any partial joins here. I tried to make first and second conditions with full outer joins too:
INGRP1.DISTRICT_ID (+) = INGRP2.DISTRICT_ID (+) And
INGRP1.CHARGE_PERIOD_ID (+) = INGRP2.CHARGE_PERIOD_ID (+) And
INGRP1.UTL_ID (+) = INGRP2.UTL_ID (+) And
INGRP1.DISTRICT_ID IS NOT NULL And
INGRP2.DISTRICT_ID IS NOT NULL
If I do this, validation reports the same error, but six times instead of twice.
If I remove outer joins OWB generates following mapping statement:

What does it mean? Is JOINER's full outer join is incompatible with KEY LOOKUP operator and KL should be replaced with WB_LOOKUP_NUM?

Sanders,
Key lookup always does a partial outer join. When the full outer join and partial outer join conditions are put together, there is no available syntax to facilitate it.
The way to this to generate the join operator (with full outer join) first in a subquery, then generate the key lookup as the outer query. Or the other way around, first the key lookup then the full outer join. The important part is that the key lookup can't be merged into the FROM-list.
So there are two workarounds. One is what you already pointed out, using WB_LOOKUP_NUM.
The other is to explicitly spell out the key lookup logic in the mapping by introducing a join with the lookup table, like this.
Change
Table1
.......... Join (w/ foj cond.) ---> KeyLookup
Table2
to
Table1
.......... Join (w/ foj cond)
Table2 ........................ Join (w/ poj cond.) ---> Lookup table

How can I join/Full outer join two different columns instead of union all?

Hi,
I have a scenario as the following:
I am performing set operations using obiee 11g where I want to take values from two different criteria. Howwver, I dont want union to take place, instead i want join to take place to see all the columns in the output.
For that, I tried changing the sql in advanced tab and tried to put full outer join instead of union all but its not allowing me to change.
How can I achieve it? please help.
Thanks.

Hi,
My problem is that I am unable to modify the sql in advanced tab. Probably due to some security reason,it's restricting me to change.
Can you suggest me a way to change it?
Thanks..

Join-types right & full outer join with Datasets

Hello
I use Crystal Reports XI Release 2 with ADO.NET Datasets as datasource. In the "Database-Expert" I try to set the "Link-Options". Unfortunately are the join-types "right outer join" and "full outer join" disabled.
- Is this because of the datasource Dataset?
- Is there e possibility to build the Dataset so I can use this two joins?
- If not, is it possible in a newer version?
Thanks, T.Fitzi

Hi
I think this is the problem. I don't connect directly to a database. My application (C#) provieds Crystal Report with a dataset. So all my data is in this dataset.
Are this joins in the new version stil disabled?

What's faster - full outer join or sum a union

Hello,
what do you think it's the best way to bring two tables together? Full outer join (1) or sum over a union (2)?
1.
select a.id nvl(a.x,0) ,nvl(b.y,0) from
a full outer join b
where a.id=b.id
2.
select id, sun(x), sum(y) from
(select id, x,0 y from a
union all
select id, 0 x, y from b )
group by id;
The ids are primary keys and ca. 80% of ids in a are found in b and vice versa.
Both tables have about 20 mio datasets.
Thank for thinking about
Stephan

Like so many things in Oracle, the answer is it depends. Various factors such as resources available (memory, CPU, disk speed etc.), size of the tables, and the indexes available will all influence the performance of a given query.
Having said that, my guess would be that the UNION ALL query would be faster than the full outer join, since ther is less work involved. However, the optimized may be smart enough to re-write the full outer join as a union all.
Another approach which might be worth benchmarking is:
SELECT id, SUM(x), SUM(y)
FROM (SELECT id, SUM(x), 0 y
      FROM a
      GROUP BY id
      UNION ALL
      SELECT id, 0, SUM(y) y
      FROM b
      GROUP BY id)HTH

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)
GROUP BY trunkTTFN

Help Required in full outer Join

I feel the below query can be changed to full outer join. But, I've not been able to do so.
I require your help in changing it to full outer join. My current query is

I do not think that query is doing what you think that it is doing - on first inspection, it was not doing what I thought either due to the order in which the UNION and MINUS operators are performed. If the FILECREATEDT column is defined as a DATE, your query is relying on an implicit date conversion - in such a case, you should replace:
filecreatedt='18-feb-2011'With:
filecreatedt=TO_DATE('18-feb-2011','DD-MON-YYYY')Now, building a simple model to explain what is happening, we create two tables with 10 rows each. The first table has C1 values that increase by 2, while the second has C1 values that increase by 3:
CREATE TABLE T1 AS
SELECT
ROWNUM*2 C1,
TRUNC(SYSDATE)+ROWNUM*2 C2
FROM
DUAL
CONNECT BY
LEVEL<=10;
CREATE TABLE T2 AS
SELECT
ROWNUM*3 C1,
TRUNC(SYSDATE)+ROWNUM*3 C2
FROM
DUAL
CONNECT BY
LEVEL<=10;It appears that the intended result of your query is to obtain a distinct list of those rows that are in each table that are not in both tables - the UNION ALL minus the intersection of the rows in two tables. However, that is not what you are achieving with that query. To demonstrate, the two halves of your query:
SELECT
C1,
C2

T1
MINUS

C1,

T2;

24 22-MAR-11
27 25-MAR-11
30 28-MAR-11As can be seen by the above, each half returned 7 rows - there are 7 rows in each table that is not in the other table. Common sense would state that if we UNION these two results (assuming no duplicate values in each table), we would see 14 rows:
SELECT
C1,
C2
FROM
T1
MINUS
SELECT
C1,
C2
FROM
T2
UNION
SELECT
C1,
C2
FROM
T2
MINUS
SELECT
C1,
C2
FROM
T1;

27 25-MAR-11
30 28-MAR-11Only 7 rows? Let's try again with the help of inline views to control the order in which the MINUS and UNION operators are processed:
SELECT
FROM
(SELECT
    C1,
    C2
FROM
    T1
MINUS
SELECT
    C1,
    C2
FROM
    T2)
UNION
SELECT
FROM
(SELECT
    C1,
    C2
FROM
    T2
MINUS
SELECT
    C1,
    C2
FROM
    T1);

27 25-MAR-11
30 28-MAR-11Note that the above returned 14 rows. We can do the same using just two outer joins:
SELECT
T1.C1,
T1.C2
FROM
T1,
T2
WHERE
T1.C1=T2.C1(+)
AND T2.C1 IS NULL
UNION
SELECT
T2.C1,
T2.C2
FROM
T1,
T2
WHERE
T2.C1=T1.C1(+)
AND T1.C1 IS NULL;

21 19-MAR-11
24 22-MAR-11
27 25-MAR-11
30 28-MAR-11Or we can do it with a full outer join and a MINUS operator:
SELECT
NVL(T1.C1,T2.C1) C1,
NVL2(T1.C1,T1.C2,T2.C2) C2
FROM
T1 FULL OUTER JOIN T2
    ON T1.C1=T2.C1
MINUS
SELECT
T1.C1,
T1.C2
FROM
T1,
T2
WHERE
T1.C1=T2.C1;

21 19-MAR-11
24 22-MAR-11
27 25-MAR-11
30 28-MAR-11Or just with a full outer join with a WHERE clause:
SELECT
NVL(T1.C1,T2.C1) C1,
NVL2(T1.C1,T1.C2,T2.C2) C2
FROM
T1 FULL OUTER JOIN T2
    ON T1.C1=T2.C1

You must be aware that you must cascade full outer joins
with
t1 as
(select 1 key,1.1 data from dual union all
select 3,1.3 from dual union all
