Oute Joined table with VPD

I'm having trouble with getting my select to work correctly on a table that is outer_joined AND has a VPD policy associaed with it. Employees are set with specific departments or departments are left blank. I want the employees to see only their department records but also see the ones that are blank. I know I can use a UNION, but I want this to be in a select.
What I am seeing is the user is getting returned all_rows (even ones that are not their department), but it's blanking out the Dept_desc value for the ones they dont have security for.
Emp_name____________Dept_Desc
Bob_________________Sales
Mike_________________Sales
Tom_________________________ *Tom's Dept_Desc is 'HR' SHOULD NOT show up in select
Joe__________________________ * Joe's Dept_Desc is blank so this SHOULD show up in select
My current select is:
select Emp_name, Dept_desc
from DEPT B, EMP A
where B.DEPT_NO(+) = A.DEPT_NO
My tables are like this:
EMP
Emp_ID
Emp_name
DEPT
Dept_ID
Dept_Name
The VPD on my DEPT table would be set like this:
Dept_Name = 'Sales'

You predicate function on VPD needs to be modified. Something like
FUNCTION the_predicate(p_schema VARCHAR2,p_name VARCHAR2)
RETURN VARCHAR2 IS
v_context_val VARCHAR2(100):=SYS_CONTEXT(c_context,c_attribute);
v_restriction VARCHAR2(4000);
BEGIN
v_restriction:='(deptno IS NULL OR deptno='||v_context_val;
RETURN v_restriction;
END the_predicate;PS: Not tested.

Conditions on Outer Joined Tables

I'm trying to understand how Discoverer handles conditions created on outer joined tables. We're using Discoverer Plus 11.1.1.3.
I have a query using two tables connected by an outer join. While I want all records back from the first table, I don't want all records back from the outer joined table. So, if I typed the SQL directly in a SQL Editor, I would put the '(+)' in each condition. However, I find that in Discoverer, sometimes it does this, and sometimes it doesn't. If it does not put the '(+)' on all conditions as well as the join, that essentially nullifies the outer join and makes it an standard join.
For example, I expanded an item on the outer joined table in the Items dialog to see its list of values, and selected one, to add the column to the worksheet and create a condition. No (+). But when I deleted this and created the condition using the Condition dialog, I got a (+). Then I created another condition using the condition dialog. I used the IN operator and pasted in a list (this item had no item class to choose from)--no (+).
When I tried manually adding (+) after the item name in the condition dialog, it put quotes around the whole thing and treated it as a string.
I can find nothing in the documentation that discusses this. Is is possible to control whether or not it uses the (+)?
Thank you, Scott Newman

Dear Michael,
Last night I had a call from user who was experiencing a very strange behaviour of her Discoverer workbook.
I replicated the issue on my machine and could not believe my eyes. A condition on an item was being ignored. I then analysed the workbook and realised it was due to a condition on an item from an outer-joined folder. I did not have the strength after a long day to deal with it and was looking forward to having some fun the next day. Firstly, I tried few tricks such as NVL, LENGTH functions in a test query in Toad. I hate to give up but I did and searched threads on this forum and opened few. The very first thread I read was this one and I laughed when I read your advice. Only until the moment I tested it in the troubled workbook. It worked like a charm. I take my hat off to you Michael. I have rarely experienced such a satisfaction when solving a tricky problem during my 9-year-long Oracle Discoverer journey. This goes straight to my little text file with interesting problems and solutions.
Thank you very much. I owe you a beer or two.
It is great to have an expert like you, always ready to share his knowledge with his colleagues.
P.S.
My apologies for this massive post, I could not resist expressing my joy and gratitude.

Illegal selection by InfoObject from outer join table

Hi all,
in any infoset with left-outer-join, when i want to select any field (infoobject) to get exlude conditions i got these errors:
illegal selection by InfoObject from outer join table.
error reading the data of infoprovider '*'.
thanks in advance .

Hi Dorota,
Choudhary S was right.
İ have notified the SAP about this issue..they wrote me below note :
As SAP tables have no concept for NULL, we
have to restrict this condition to not allow excluding condition to be
used any more. But alternatively, you could use including to replace it.
Please check my last reply to see the detailed reason for it, and
this explaination is from our development colleagues.
For this note 1435772, you could also see why this error message
arises.
So, they said it is not possible in case of left outer join after those patches.
i just used include to replace that exluding condition.it takes little time but the problem is solving.
Thanks

Join table with additional data

Hi,
I'm new to JPA (Toplink Essentials) and I'd like to know how to handle this situation:
I have ORDER table, ITEMS table and "join table" ORDER_ITEMS which holds refernces to ordered items with quantity of each oredered item.
Many thanks

I did mapping as shown in listing. It works for reading, but for writing JPA returns error. Can somebody help?

VPD problem: select for update on join tables with policy on ref table

In our application we use VPD. Now we ran into an issue. I will try to explain with EMP and DEPT table.
EMP table has no VPD attached.
DEPT table has VPD policy that forbids all updates, but allows select. (Policy returns '1=2' for statement type update.
This query returns no rows:
select * from emp join dept using (department_id) for update. This makes sense, because I'm going to update both the tables.
However:
select * from emp join dept using (department_id) for update of employee_id also returns no rows. THIS IS WRONG. I'm not going to update dept table.
Any experience with this. Is this a known limitation ?

I can see all the rows, because there is no select policy.
However the point is, that VPD should allow me to update the emp table, because there is no update policy.
With the 'for update of employee_id' clause, VPD should recognize that I'm not going to update the dept table, but only the emp table. But VPD does not recognize this, but applies the update policy of dept to the statement, making the statement to update no rows.
(Reason behind my question is ADF Business Components, where you have ViewObjects with Referenced Entities. ADF BC generates this type of statement and now we run into this VDP limitation)

Issues with limit/filter on outer join table in BQY

I'm converting a series of BQY's from Brio 6.6 to Hyperion 9.3. I have some questions about the "use ODBC outer join syntax on limits" option in the OCE. I sort of understand this option's purpose, but I don't completely understand the SQL I'm seeing. For example Brio 6.6 is generating the following SQL statement:
SELECT * FROM tblA AL1 LEFT OUTER JOIN tblB AL38 ON (AL38.ParentID=AL1.ChildID AND
AL38.Data='SomeData') WHERE ((NOT AL38.Action IS NULL))
Now, Hyperion 9.3 generated the SQL statement as follows:
SELECT * FROM tblA AL1 LEFT OUTER JOIN tblB AL38 ON (AL38.ParentID=AL1.ChildID AND
AL38.Data='SomeData') AND (NOT AL38.Response IS NULL))
My questions are:
1) Why isn't the "NOT AL38.Action IS NULL" statement included in the outer join in Brio? My limited understanding of the "use ODBC outer join syntax on limits" seems to indicate that it should end up there. I want the SQL to look like this, but I don't know why Brio generates this SQL.
2) How can I get Hyperion to generate the same SQL as Brio? And still use the OCE with "use ODBC outer join syntax on limits" selected?

Setting the Cardinality of Department > Employee role to OptionalOne
gives rise to cartesian join (which is a bigger issue).
Therefore, the Cardinality of Department > Employee role should remain as
OptionalMany (default).
This means, the outer join problem still remains unsolved. I have, therefore,
unmarked the above answer by me.
The question is - why has Report Builder been designed in such a way that the primary entity is always the child entity when attributes are selected from both parent and child entities?
Most people desire that all the rows of the parent entity be fetched irrespective of whether there are corresponding rows in the child entity or not. Report Builder tool should not dictate what the user wants to get, meaning it is not right to assume
that the focus of the report is Employee when attributes are selected from both Department and Employee. Report Builder should not make the child entity (i.e., Employee) as the primary entity when the user selects attributes from the child entity after
having selected attributes from the parent entity.
I am sorry to say that clients may not accept the Report Builder tool as this does not fetch the records as desired.
I hope there is someone who can suggest how the outer join problem can be solved by just tweaking the properties of the report model (SMDL).
Besides, the end users are business users and are not tech savvy. They are not expected to modify queries. They would simply drag and drop attributes from entities to create adhoc reports.

How do I find missing entries in outer join table?

Hi all,
I am trying to find records in table1 that are missing in table2. This is a simple process in SQL, but ABAP is giving me trouble. I want to do this using an outer join.
Example:
Select table1~docnumber
From table1
Left Outer Join table2
On table1docnumber = table2docnumber
Where table2~docnumber IS NULL. (the record is missing in table2)
Note: ABAP gives an error and wants me to use the Having Clause, which is ok, but then ABAP wants me to use Group By, which ok, but then I still get the same syntex error.
Any thoughts on doing this with the outer join and is null options. I do not want to select into two internal tables and compare them.

All,
I am not trying to do a subquery. Just a simple outer join where I know some records are missing in the second table.
Here is the code:
select eban~banfn
into table i_delay_banfn
from eban
left outer join zsmt_prdelay_upd
on eban~banfn = zsmt_prdelay_upd~banfn
where zsmt_prdelay_upd~banfn IS NULL.
Here is the error message:
No fields from the right-hand table of a LEFT OUTER JOIN may appear in
the WHERE condition: "ZSMT_PRDELAY_UPD~BANFN".
select eban~banfn
into table i_delay_banfn
from eban
left outer join zsmt_prdelay_upd
on eban~banfn = zsmt_prdelay_upd~banfn
having zsmt_prdelay_upd~banfn IS NULL.
Please use code tags

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

... 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 Joins possible with VPD predicates?

Hi everybody,
I have read the articles about VPD and row level security. What occurs to me is that all examples return predicates where the WHERE clause selects from the same table as the FROM clause. Is there a way to generate a predicate that goes to other tables as well?
Example:
table_1 holds sales records information, e.g.:
product, price, date of sale transaction.
table_2 holds information about the customers, e.g.:
customer_company, product, price, date_of_sale_transaction.
table_3 holds information about the customer account managers, e.g.:
employee_id, family_name, name, customer_company, customer_department.
Now if an account manager logs in to the database he shall only see the sold products in table_1 which were bought by the customers who he is in charge of. The select statement would something like:
select t1.product, t1.price from table_1 t1, table_2 t2, table_3 t3 where t1.product=t2.product and t2.customer_company=t3.customer_company and t3.employee_id=?
Certainly, ? would be the the id of the logged in user.
How can I realize a JOIN like this with VPD?
Thank you for every help!
Jie

Jie,
This is trivial to do in VPD. In your case, you would define a different policy on each table. For instance, the policy function for the policy on table_3 will return a preciate
employee_id = USER
or something similar. The policy function for policy on table_2 will return
customer_company in (select customer_company from table_1)
Similarly, the function for table_1 will return
product_in (select product from table_2)
However, you will note that the query containing IN quickly becomes inefficient when the data volume is high. Therefore, an alternative solution may be in order. One option is to use application contexts where you prepopulate the values when the user logs in and use that in the predicate. It's not possible to describe the whole procedure here; but youmay find the paper I presented at New York Oracle User Group helpful at my website www.proligence.com/nyoug_fgac.pdf.
Hope this helps.

Using Left Outer Join along with reference

I have three tables.
Table 1 : BOOK_DETAILS
Fields: BOOK_ID, BOOK_NAME

Fields: BOOK_ID, USER_NAME
Table 3: BOOK_AUTHOR
Fields: BOOK_ID, AUTHOR_NAME

Again I have to display the Book Author name for each Book.
I am able to create a query with the Left outer join between Table 1 and Table 2. However I am not able to give a reference to the Table 3.
Can any one please help me with this.

Can we join table with structure

Hi
i have taken fields from Plaf table and some fields from structures so now i want to join that how can i join.
Is there any option?
regards

Hi,
structure dont have any data base table associated with them so they dont have any data.
that's why we cannot join structure witha table but we can include a structure within any table.
Sytex to include structure in ztable:
fieldname data element.
.include struname
hope it will ans ur query.
Thanks

Join table with an object type

Hi,
I would like ot know how to join a table with another table having an object type as a column value.
For ex:
Create type add_obj as object (st varchar2(10), city varchar2(10), zip varchar2(10));
Table A
Cust_id number
cust_address add_obj
Table B
Cust_id number
order_id number
I want to select the complete address for each order.
Is this the correct way to do this select:
Select o.order_id, c.customer_id, c.cust_address.st, c.cust_address.city, c.cust_address.zip
from table A c, table B o;
Any leads is appreciated. Thanks in advance.

>
unfortunately with a crashed Oracle db I could try nothing.... Forums are for getting help and offering help in times of need.
Will take your advice some other time. Now need help on how to select the address city, st and zip along with the order_id.
>
Ah - I understand - you mean before your class is over.
Unfortunately with a crashed Oracle db you will not know if our advice is correct or not since you won't be able to test it.
So I will offer advice some other time. Now need to get some fresh air and a hot cup of coffee.
Let us know when you DB is back up and you have run your tests. Then if you still have any questions other forum members may decide to help you. Well - if their database is up and running that is.

Many to many join table with different column names

Hi have a joint table with different column names as foreign keys in the joining
tables...
e.g. i have a many to many reltnshp btwn Table A and Table B ..and join table
C
both have a column called pk.
and the join table C has columns call fk1 and fk2
does cmd require the same column name in the join table as in the joining table?
are there any workarounds?
thanks

HI,
No, the foreign key column names in the join table do not have to match the primary
key names in the joined tables.

Joining tables with SQL in Crystal XI

I am new to Crsytal Reports. I want to join 2 tables using a formula, which I am trying to do in SQL. I created a simple test report and I can get it to work if I don't put any fields on the report from the joined table. ie - if I just use fields from "sal-rep" the report works. As soon as I add a field from "freight" (my joined table) the report will not display anything. (but I don't get any error messages - just a blank report). Here is my SQL:
SELECT "sal-rep"."full-name","sal-rep"."invoice-nbr","freight"."misc-charge-ammount" FROM   "PUB"."sal-rep" INNER JOIN "PUB"."FREIGHT" ON ("sal-rep"."invoice-nbr"="freight"."invoice-nbr") WHERE "sal-rep"."invoice-nbr"='0000189957'

I got it to work!!!   This is the SQL I used -
SELECT "sal_rep"."full-name", "sal_rep"."invoice-nbr", "freight"."misc-charge-ammount", "freight"."invoice-date"
FROM   "PUB"."freight" "freight" INNER JOIN "PUB"."sal-rep" "sal_rep" ON ("freight"."invoice-nbr"="sal_rep"."invoice-nbr") AND ("freight"."invoice-date"="sal_rep"."inv-date")
WHERE "sal_rep"."invoice-nbr"='0000189957'
Now when I look at the Table used in Database expert it lists - Command and Freight.
Before it was listing Command and Sal-Rep.
Not sure I understand why, but at least it's working.
thanks for your help - really appreciated!

Need sql query to find out Joins attached with folders in Discoverer

Hi,
Can anyone let me know the sql query which can be used to identify the joins which are attached to the folders.
Actually we have to identify all the joins conditions from folders those are migrated from one instance to others.
Thanks

I recommend that you implement the admin EUL supplied by oracle, you can get there a lot of repository information (metalink note: 556932.1).
Try to use this (maybe you will need some pkg's):
SELECT
DECODE(KEYS.FK_MANDATORY,
1,
'Always exist in master folder',
'Might not exist in master folder') "Detail Item values",
