Removing full outer joins
Hi All,
I am creating reports from two fact tables. However, in spite of using only inner joins in RPD, obiee is generating full outer joins between two WITH (sub-query factoring) . Is there a way to enforce inner joins.
Thanks

All the joins in RPD are inner joins. The query generated is similar as follows. The full outer join is automatically created between SAWITH0 SAWITH1
WITH
SAWITH0 AS (SELECT sum(T245.QUANTITY_SOLD) AS c1,
T161.CHANNEL_DESC AS c2
FROM
SH.CHANNELS T161,
SH.SALES T245
WHERE ( T161.CHANNEL_ID = T245.CHANNEL_ID )
GROUP BY T161.CHANNEL_DESC),
SAWITH1 AS (SELECT sum(T168.UNIT_COST) AS c1,
T161.CHANNEL_DESC AS c2
FROM
SH.CHANNELS T161,
SH.COSTS T168
WHERE ( T161.CHANNEL_ID = T168.CHANNEL_ID )
GROUP BY T161.CHANNEL_DESC)
SELECT DISTINCT case when SAWITH1.c2 IS NOT NULL then SAWITH1.c2 when SAWITH0.c2 IS NOT NULL then SAWITH0.c2 end AS c1,
SAWITH0.c1 AS c2,
SAWITH1.c1 AS c3
FROM
SAWITH0 FULL OUTER JOIN SAWITH1 ON SAWITH0.c2 = SAWITH1.c2
ORDER BY c1
If I change the underlined FULL OUTER JOIN above to just "JOIN", the query returns what I want.

When I run the above query I get a problem.
I am expecting to see is a merge of all the attribute_id's and their values.
The query does not appear to be merging the data as intended.
My understanding of the full outer join is that its a combination of left and outer joins,
so the above query is intended to return with the total number of unique attributes
and their appropriate values
a) I have a bug in the Sql
b) This is an oracle bug
c) My understanding is incorrect
Please Help

Keith Jamieson (fixed insert statements for gtt )How do you expect a full outer join operation when you have given --
where c.partner_id=710326;According to your supplied data - i don't think your query can perform that full outer join operation because of that filtration. Just remove that last condition and checked it. You will get your desired result - hopefully.
"It's like you want to view the things by closing down your both eyes". Do you think it will pay?

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.

[8i] Need help with full outer join combined with a cross-join....
I can't figure out how to combine a full outer join with another type of join ... is this possible?
Here's some create table and insert statements for some basic sample data:
CREATE TABLE my_tab1
( record_id NUMBER NOT NULL
, workstation VARCHAR2(4)
, my_value NUMBER
CONSTRAINT my_tab1_pk PRIMARY KEY (record_id)
INSERT INTO my_tab1
VALUES(1,'ABCD',10);
INSERT INTO my_tab1
VALUES(2,'ABCD',15);
INSERT INTO my_tab1
VALUES(3,'ABCD',5);
INSERT INTO my_tab1
VALUES(4,'A123',5);
INSERT INTO my_tab1
VALUES(5,'A123',10);
INSERT INTO my_tab1
VALUES(6,'A123',20);
INSERT INTO my_tab1
VALUES(7,'????',5);
CREATE TABLE my_tab2
( workstation VARCHAR2(4)
, wkstn_name VARCHAR2(20)
CONSTRAINT my_tab2_pk PRIMARY KEY (workstation)
INSERT INTO my_tab2
VALUES('ABCD','WKSTN 1');
INSERT INTO my_tab2
VALUES('A123','WKSTN 2');
INSERT INTO my_tab2
VALUES('B456','WKSTN 3');
CREATE TABLE my_tab3
( my_nbr1 NUMBER
, my_nbr2 NUMBER
INSERT INTO my_tab3
VALUES(1,2);
INSERT INTO my_tab3
VALUES(2,3);
INSERT INTO my_tab3
VALUES(3,4);And, the results I want to get:
workstation sum(my_value) wkstn_name my_nbr1 my_nbr2
ABCD 30 WKSTN 1 1 2
ABCD 30 WKSTN 1 2 3
ABCD 30 WKSTN 1 3 4
A123 35 WKSTN 2 1 2
A123 35 WKSTN 2 2 3
A123 35 WKSTN 2 3 4
B456 0 WKSTN 3 1 2
B456 0 WKSTN 3 2 3
B456 0 WKSTN 3 3 4
???? 5 NULL 1 2
???? 5 NULL 2 3
???? 5 NULL 3 4I've tried a number of different things, googled my problem, and no luck yet...
SELECT t1.workstation
, SUM(t1.my_value)
, t2.wkstn_name
, t3.my_nbr1
, t3.my_nbr2
FROM my_tab1 t1
, my_tab2 t2
, my_tab3 t3
...So, what I want is a full outer join of t1 and t2 on workstation, and a cross-join of that with t3. I'm wondering if I can't find any examples of this online because it's not possible....
Note: I'm stuck dealing with Oracle 8i
Thanks!!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!

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. -
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

Hi All,
The issue may be silly, but we cant make it out:

Thanks,
JeneeshNot 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

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.

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..
select
fromUnionAll.cdate, fromUnionAll.part_no,
sum(fromUnionAll.O_qty) O_qty,
sum(fromUnionAll.I_qty) I_qty
from
select
iinner.cdate, iinner.part_no, 0 O_qty, iinner.I_qty
from
select
i.cdate, ii.part_no,
/* added the case only for the extreme case when there is
no record anywhere for the given CDATE in INCOMMING_item */
sum( ( case when ii.qty is not null then ii.qty else 0 end) ) I_qty
from
incomming i,
incomming_item ii
where
i.iid = ii.iid (+)
group by i.cdate, ii.part_no
) iinner
union all
select
oinner.cdate, oinner.part_no, oinner.O_qty, 0 I_qty
from
select
o.cdate, oi.part_no,
/* added the case only for the extreme case when there is
no record anywhere for the given CDATE in OUTGOING_item */
sum( ( case when oi.qty is not null then oi.qty else 0 end) ) O_qty
from
outgoing o,
outgoing_item oi
where
o.oid = oi.oid (+)
group by o.cdate, oi.part_no
) oinner
) fromUnionAll
group by fromUnionAll.cdate, fromUnionAll.part_no;

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.. -

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? -
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

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
SELECT CLAIMNO,'1' INDX FROM D_CLAIM@CMS2PROD
WHERE clntsys=76500 and facility=76501 and filecreatedt='18-feb-2011' and fileupdatedt is null
MINUS
SELECT CLAIMNO,'1' FROM D_CLAIM
WHERE clntsys=76500 and facility=76501 and filecreatedt='18-feb-2011' and fileupdatedt is null
UNION
SELECT CLAIMNO,'2' FROM D_CLAIM
WHERE clntsys=76500 and facility=76501 and filecreatedt='18-feb-2011' and fileupdatedt is null
MINUS
SELECT CLAIMNO,'2' FROM D_CLAIM@cms2prod
WHERE clntsys=76500 and facility=76501 and filecreatedt='18-feb-2011' and fileupdatedt is nulldonisback wrote:

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
FROM
T1
MINUS
SELECT
C1,
C2
FROM
T2;
C1 C2

SELECT
C1,

SELECT

21 19-MAR-11
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,

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);

24 22-MAR-11
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
WHERE
(T1.C1 IS NULL
OR T2.C1 IS NULL);

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.FitziHi
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?
