Outer Join on view hangs

Hi there,
sorry about the big post but I am wondering if someone could help me with this. I dont seem to be able to figure out what I am doing wrong here:
I've created a function that merges a number of lines of text into one row, the function works fine if I call it directly:
CREATE FUNCTION "LONG_TEXT" (code IN VARCHAR2, inc_no IN VARCHAR2)
RETURN VARCHAR2 IS
text_full VARCHAR2(32767);
BEGIN
FOR r IN ( SELECT bo_text
FROM text_table
WHERE SUBSTR(bo_key,1,4) = code
AND SUBSTR(bo_key,5,10) = inc_no
AND bo_text_code = 'IT'
ORDER BY LINE_NO)
LOOP
text_full := text_full || ' ' || trim(r.bo_text);
END LOOP;
RETURN trim(text_full);
END long_text;
I've called the function in a view - works fine when I call it directly:
CREATE OR REPLACE VIEW "EEV097_IT" ("CODE","INC_NO","BO_TEXT") AS SELECT DISTINCT SUBSTR(bo_key,1,4) AS code,
SUBSTR(bo_key,5,10) AS inc_no,
long_text(SUBSTR(bo_key,1,4),SUBSTR(bo_key,5,10)) AS bo_text
FROM text_table
WHERE bo_text_code = 'IT'
Then I've joined the view to another table. This statement actually works:
SELECT
EEV097_IT.CODE,
EEV097_IT.BO_TEXT,
EEV097_IT.INC_NO,
INC_DIM.REV_OCC_DATE
FROM
INC_DIM
LEFT OUTER JOIN
EEV097_IT ON EEV097_IT.CODE=INC_DIM.CODE AND
EEV097_IT.INC_NO=INC_DIM.INC_NO
WHERE
INC_DIM.BO_USER_ID = 'L83321' AND
INC_DIM.REV_OCC_DATE BETWEEN '19/FEB/07' AND '23/FEB/07'
INC_DIM.INC_NO = '1234';
but as soon as it take this line "INC_DIM.INC_NO = '1234'" out of the where clause or add a second inc_no something like INC_DIM.INC_NO in ('1234','2345'); oracle hangs when I execute this statement - At the end of the day I dont want to specify a inc_no in the where clause at all - The expected result is quite small just about 10 rows I am using oracle version 11.1.0.6.
If someone has an idea please let me - there would be one work around to put the view as a nested selected into the statement that works fine, but I can't use it. I basically need to end up with a view that I can join to the other table like I did above - so the fix needs to be in the view or in the function.
thanks

Outer join in view criteria

Hi everybody
I use jdeveloper 11.1.1.6.0
I want to create outer join in view criteria, so I had to override getCriteriaItemClause method in ViewObjImpl.java
my query is like this :
SELECT t1.row_no, t2.type FROM   table_1 t1 , table_2 t2
WHERE   t1.row_no(+) = t2.row_no
and       t1.user_Id(+) = :bindVar
table_1(row_no, user_Id )
table_2(row_no,type)
the part   " t1.user_Id(+) = :bindVar " should be put in the view criteria
the method:
    @Override
    public String getCriteriaItemClause(ViewCriteriaItem viewCriteriaItem) {
            String newQeury =this.getEntityDef(0).getAliasName() + "." + viewCriteriaItem.getColumnName() + "(+) = :bindVar ";
            return newQeury;
but when I run the view criteria the exception below raises:
oracle.jbo.expr.JISyntaxError: JBO-36000: An unexpected expression token is found.
when I remove sign "(+)" from newQeury
   String newQeury =this.getEntityDef(0).getAliasName() + "." + viewCriteriaItem.getColumnName() + "= :bindVar "; // remove sign '(+)' before = :bindVar
the exception below raises
JBO-29000: Unexpected exception caught: oracle.jbo.expr.JIEvalException, msg=JBO-25077: Name t1 not found in the given object: ViewRow [oracle.jbo.Key[5 1 5 ]].

Outer join in view criteria: how to ?

Hello,
I have to create a VO for a LOV. I created in this VO a ViewCriteria to pass variables for the query.
The problem is that for one of this variable I have to set the clause as an outer join.
JDeveloper creates:
SELECT MyView1.Item, MyView2.Code
FROM MyView1, MyView2
WHERE MyView1.ID = MyView2.EXT_ID (+)
AND MyView1.Item = :TheItem
AND MyView2.Code = :TheCodebut I need something like:
SELECT MyView1.Item, MyView2.Code
FROM MyView1, MyView2
WHERE MyView1.ID = MyView2.EXT_ID (+)
AND MyView1.Item = :TheItem
AND :TheCode = MyView2.Code (+)

ADFboy wrote:
this is optional parameter value, in the view criteria windows is this option....
AdfBoyNo, this parameter is not optional because, in the call of the LOV it will be always set.
But the query without the outer join returns too few rows...
I tried to find where to "intercept" this programmatically, but I'm failing doing this. :(
I'll have the same problem with another field, not for a LOV but to get the value of an attribute of a VO.
Even in advanced mode the Where clause can't have parameters...

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.

Create a view that limits a large table, but also allows an outer join ?

MY_PAY_ITEMS is a table that stores payslip line items. It has a total size of 500,000,000 rows.
EMP is the unique employee id, We have approx 200,000 employees (with approx 50,000 being active today).
PAY_PRD is a weekly pointer (2010-01, 2010-02 ... 2010-52), we have data from 2004 and are adding a new pay period every week. 2010-01 is defined as the first monday in 2010 to the first sunday in 2010 etc.
KEY1 is an internal key, it tracks the timeline within the pay period.
KEY2 is a child of KEY1, it tracks the sequence of events within KEY1.
LN_ITEM is the actual pay item that resulted from the event on average a person generates 20 rows per event. Note that in this example everybody gets the same LN_ITEM values, but in practice it is 20 selected from 300
ITEM_AMT is the net pay for the line item.
FILLER is an assortment of fields that are irrelevant to this question, but do act as a drag on any row loads.
MY_ITEM_DISPLAY is a table that describes how certain screens should display items. The screen itself is a 4 column grid, with the contents of the individual cells being defined as a lookup of LN_ITEMS to retrieve the relevant LN_AMT.
We have an application that receives a DISPLAY_CODE and an EMP. It automatically creates a sql statement along the lines of
SELECT * FROM MY_VIEW WHERE DISPLAY_CODE = :1 AND EMP = :2
and renders the output for the user.
My challenge is that I need to rewrite MY_VIEW as follows:
1) Select the relevant rows from MY_ITEM_DISPLAY where DISPLAY_CODE = :1
2) Select the relevant all rows from MY_PAY_ITEMS that satisfy the criteria
   a) EMP = :2
   b) PAY_PRD = (most recent one for EMP as at sysdate, thus if they last got paid in 2010-04 , return 2010-04)
   c) KEY1 = (highest key1 within EMP and PAY_PRD)
   d) KEY2 = (highest key2 within EMP, PAY_PRD and KEY1)
3) I then need to cross reference these to create a tabular output
4) Finally I have to return a line of 0's where no LN_ITEMs exist ( DISPLAY_CODE 01, sequence 40 contains impossible values for this scenario)
The below query does part of it (but not the PAY_PRD, KEY1, KEy2 )
select * from (
SELECT A.DISPLAY_CODE
, B.EMP
, A.SEQUENCE
, MAX(DECODE(B.LN_ITEM, A.COLUMN_ITEM1, B.ITEM_AMT, 0)) "COL1"
, MAX(DECODE(B.LN_ITEM, A.COLUMN_ITEM2, B.ITEM_AMT, 0)) "COL2"
, MAX(DECODE(B.LN_ITEM, A.COLUMN_ITEM3, B.ITEM_AMT, 0)) "COL3"
, MAX(DECODE(B.LN_ITEM, A.COLUMN_ITEM4, B.ITEM_AMT, 0)) "COL4"
FROM MY_ITEM_DISPLAY A, MY_PAY_ITEMS B
WHERE B.PAY_PRD = '2010-03'
GROUP BY A.DISPLAY_CODE, B.EMP, A.SEQUENCE)
WHERE DISPLAY_CODE = '01'
AND EMP = '0000011'
ORDER BY SEQUENCE
My questions
1) How do I do the PAY_PRD, KEY1, KEY2 constraint, can I use some form of ROW_NUMBER() OVER function ?
2) How do I handle the fact that none of the 4 column LN_ITEMS may exist (see sequence 40, none of those line items can exist)... Ideally the above SQL should return
01, 0000011, 10, <some number>, <some number>, <some number>, <some number>
01, 0000011, 20, <some number>, <some number>, <some number>, <some number>
01, 0000011, 30, <some number>, <some number>, <some number>, <some number>
01, 0000011, 40, 0            , 0            , 0            , 0
I tried a UNION, but his prevented the view from eliminating the bulk of the MY_PAY_ITEMS rows, as it resolve ALL of MY_PAY_ITEMS instead of just retrieving rows for the one EMP passed to the view. The same seems to be true for any outer joins.

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 will paste both the contract lines and contract flexfields source - I have tuned the flexfields but have done nothing to date with the lines.

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.

How to outer join within a view link from (VO-VL-VO)

I've got a table that stores the values of pre-defined attributes.
I'd like to create an advancedTable region that shows all of the attributes with or without values, in my view object i have....
select attribute, value
from attributes, values
where attributes.attribute_id = values.attribute_id (+)
This is working, but a have another view object that is the master and this is the details.
How can I do an outer join on the view link from master to detail? A simple (+) in the where condition does not do the trick.
If I try anything fancy within the view link, I get a JBO-27122.
Thank you,
Jerry.

Understand the concept of VL. Vl is nothing but a link between two VOs, with one VO row column serve as binding column for another VO.If u understand this u go to VL wizard and make VL declaratively. If not, refer to dev guide to know about VL.

View with outer join results wrong number of rows

Hi,
When i run a query on a view it returns 2 rows(2 distinct rows), when i run the same query with the select statement which the view is created , it returns only 1 row. According to data the 1 row result is correct, how come twi results. A coding sample as follows. Any help is most appreciated.
I have a view created based on a outer join of two views in the format;
create or replace view view1 as
select ord.order_no order_no,
ord.del_type del_type,
det.qty qty
from detail_view det, order_view ord
where det.site(+) = ord.site
and det.part(+) = ord.part
and nvl(ord.del_type,'_NULL_') <> 'F'
with read only;
detail_view & order_view themselves have several group by/sum and union Alls.
When i run the query on this view
[Select * from View1 where order_no = 'A30' And del_type = 'B']
it returns 2 distinct rows. But when i run the select statement which created the View1 with the query it returns only one row!!
What did i do wrong?
Thanks
Sanjeewa

I cannot reproduce this :
SCOTT@LSC01> create table detail_view(qty number,site number,part number);
Table created.
SCOTT@LSC01> create table order_view(order_no varchar2(10), del_type varchar2(1), site number,part number);
Table created.
SCOTT@LSC01>

6 where det.site(+) = ord.site
7 and det.part(+) = ord.part
8 and nvl(ord.del_type,'_NULL_') <> 'F'

Implementing Outer join Views in creating Generic datasource

Guys,
Iam bringing the Purchase document level data from R/3 into BW.I have couple
of other Ztables also from which i need to collect the information.So iam going to create a generic datasource based on the view.
In case of Database view it is taking inner join, which is undesirable since the
final data coming out of view will be reduced as we join the main base tables with ztables..Since Ztables may have very less data.And inner join gives complete information only if all tables contain the information given out in the view output.
One option is to use maintainance view which uses outer join. Is it recommendable
to use maintainance view in case of basing the Generic datasources on the view.
Please inform me if any of you have done generic datasources using database view.Any idea in this regard is welcome.

Hi,
I think you may have to develop your Generic Datasorce with "Function Module" since there is no common field.
Regards,
Suman

Views-Outer joins

Hi All,
We are using generic extraction for extracting data from PM module using views. We are getting data only if there is a match on the join condition i.e. if I am using table-A and table-B and the join condition is table-A.id=table-B.id , then we are getting data only when we have match.If table-A.id is null then we are not getting any record at all . Can we give outer join some where?
Thanks for the Help
Balraj

Hi,
I am not aware of a way doing that with generic extraction based on a ABAP view.
Perhaps with an infoset (SQ02) you'll be able to achieve that but I am not sure.
Finally you can write your own extractor to achieve your requirement. You have an example of extractor with function module RSAX_BIW_GET_DATA_SIMPLE (SE37).
hope this helps...

Try this one again, outer join with inline views

Posted this before and got no response from anyone. Can anyone advise ?
does anyone have an example of inline views combined with outer joins in the same statement ? - am currently converting app from sqlserver to oracle and sqlserver view has many left outer joins in from the same table as well as part of the outer join conditions being a subquery e.g.
select ...
from a left outer join b left outer join c
on a.col = b.col and
c.col = a.col and
a.othercol = ((select ..
from d
where ...)
OR (select ...
from e
where ...))
where ....
sometimes they are just mutliple part left outer joins but as many as 10. I guess I have to convert these to inline views then outer join to that, but not 100% sure. There may be a better way ?
null

select ...
from a,b,(select ...) dummyTable
where a.col = b.col(+)
AND a.col = dummyTable (+)
AND b.col = c.col(+)
AND ....

Outer join for a database view

Dear Experts,
Could you tell me what is the outer join and the example of this?
Is it possible I can create an outer join view for generic extraction?
Thanks.

This is what a nested loops would look like in ABAP. It is not a function module, but it could be made into one very easily.

Alternative for OUTER Join for use in fast refresh materialized view

Hi ,
I have two tables as :
CREATE TABLE TEST_SANDY1
COL1 NUMBER
CREATE TABLE TEST_SANDY2
COL1 NUMBER,
COL2 VARCHAR2(10 BYTE)
Data for the tables are :
INSERT INTO TEST_SANDY1 ( COL1 ) VALUES (
1);
INSERT INTO TEST_SANDY1 ( COL1 ) VALUES (
2);
INSERT INTO TEST_SANDY1 ( COL1 ) VALUES (
3);
COMMIT;
INSERT INTO TEST_SANDY2 ( COL1, COL2 ) VALUES (
1, 'a');
INSERT INTO TEST_SANDY2 ( COL1, COL2 ) VALUES (
2, 'b');
INSERT INTO TEST_SANDY2 ( COL1, COL2 ) VALUES (
4, 'd');
COMMIT;
Now when I run the following select statement :
select
b.col1
from
test_sandy1 a,
test_sandy2 b
where
b.COL1 = a.COL1(+)
I get :
COL1
1
2
4
I want to build a materialized view to generate the same values but it has to be fast refresh. But since I am using outer join I am unable to create a fast refresh one.
Can someone suggest an alternate select to create fast refresh materialized view.
Thanks,
Sandipan

The select statement was not fitting my problem , so I'll change it as :
select
a.col1, nvl(b.col2, 'DEFAULT')
from
test_sandy1 a,
test_sandy2 b
where
b.COL1(+) = a.COL1
I get :
COL1     VAL
1     a
2     b
3     DEFAULT
How do I this ?

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
fm

the 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.

How can I crate a view with tables which require "Left outer join"?

Hi guys,
how can I define a view with tables which require "Left outer join"?. In SE11 "View",->tab "Join condition", it seems that it valid only for "Inner Join".
Please give me some hint.
Thanks in advance.
Regards,
Liying

Hi
Inner Join and Outer Join
The data that can be selected with a view depends primarily on whether the view implements an inner join or an outer join.
With an inner join, you only get the records of the cross-product for which there is an entry in all tables used in the view.
With an outer join, records are also selected for which there is no entry in some of the tables used in the view. (ABAP allows left outer join.)
The data that can be selected with a view depends primarily on whether the view implements an inner join or an outer join.
