3 way table join for a view?

Hi,
I need to create a view comprising several complex queries (at least to me...). Below is an example where I have to do a three way table join, based on multiple columns from each table.
This is the data I need to get at:
table1."DISTRICT TYPE",
table1. "DISTRICT CODE",
table1."EO_NAME"
With the following constraints:
table1 joined with table2 via DISTRICT_TYPE and DISTRICT CODE
table2 joined with table3 via PRECINCT and PRECSUB
What is the best query to use in this situation? Or, is there a better alternative, considering I do have to create a view?
Thanks very much.

This one really is a basic join question, and a quick perusal of the SQL Reference Manual, or any basic SQL book would provide an answer. However ...
Assuming your tables look like:
TABLE1
district_type
district_code
eo_name
TABLE2
district_type
district_code
precinct
precsub
TABLE3
precinct
precsub
other_stuff
then
SELECT a.district_type, a.district_code, a.eo_name,
       b.precinct, b.precsub,
       c.other_stuff
FROM table1 a, table2 b, table3 c
WHERE a.district_type = b.district_type and
      a.district_code = b.district_code and
      b.precinct = c.precinct and
      b.precsub = c.precsub

Can do explict join for database view?

Hi all,
I would like to ask whether there is a way to specify the join condition to be outer join for database view. It is because I need to map 2 tables in the view and I want to be able to find the record in the view table if the record exists in Table A but not Table B.

Hi Jaya,
A Maintenance View helps you to maintain data that is distributed across different or multiple database tables. So, it becomes an easy way to update data and without any programing effort. You can create a Maintenance View across multiple tables with one Table as Primary Table and others as Secondary Tables. But the tables must be related with each other with a Foreign Key Relationship.
Have a look at the following link which tell you about the procedure of creating the Maintenance Views :
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21ed2d446011d189700000e8322d00/frameset.htm
Hope this helps.
Thanks,
Samantak.

Tables/Joins for logical tables being combined

I have 2 logical tables set up that have multiple physical table sources (using map to these tables). Some of the physical sources are the same in each logical table. It seems that when I make selections from Answers and look at the SQL, it is picking tables from both logical tables (instead of just the one I used). It is also grabbing the content (additional 'where condition') from the other logical table as well. Why is it doing that?

Yes it is kind of limitation in obiee. But there are some solutions which might deviate from best practices.
Sol 1. Snowflake the dimensions in Business Model. Rather than merging both of them into single logical table, separate them into two different logical tables.
Sol 2. For the logical table , have two LTSs. First LTS will have both tables and all columns mapped to both tables. Second LTS will have only main table, Columns belong to that table only mapped. In this way when you selected columns related to first source system will use second LTS which has only only one table.

SUS - Table joins for PO and Invoice

Hello,
I am trying to create a report in SUS and I'd like to join some tables.
I'd like to be able to pull all the SUS PO's and SUS Invoices filtered by Vendor and Date. Looking at BBP_PD all the data is already linked under "Header Links" but I'm not sure how to use those links in a query.
CRMD_ORDERADM_H seems to contain most of the PO and Invoice data I need but how can I connect a PO with the correct invoice?
Thanks,
Matt

Solution:
Use the following function modules to look up this data.
BBP_PD_SUSPO_GETLIST
BBP_PD_SUSPO_GETDETAIL
This returns a lot of data so you can pick and choose what you need.
Thanks,
Matt

SQL Query with 3 tables to create a view

Hi
I have got an existing view "View_output" formed with a query which works fine:
select A,B,C,D,E,F,G,H from GTS1 where D is not null
    UNION
   select A,B,C,D,E,F,G,H from GTSN1 where D is not null;It works fine, in the output I have columns A,B,C,D,E,F,G,H
New requirement : Modify the view, by adding a new column 'I' so that the view should have
columns A through I, and no column values should be null.
This column "I" is coming from a table, say DLC
Data in DLC is a subset of the original view "View_output"and DLC have the foll.columns:
("View_output" is a datablock source for a form and only selected column values are put as output in DLC
after form manipulation)
DLC is having only 5 columns -B,C,F,H,I
When I give:
(select A,B,C,D,E,F,G,H,NULLfrom GTS1 where D is not null
    UNION
   select A,B,C,D,E,F,G,H,NULL from GTSN1 where D is not null)
UNION
select NULL,B,C,NULL,NULL,F,NULL,H,I
    from
    DLC where I IS NOT NULL;It UNIONS all required rows in the 3 tables but columns A,D,E,G are NULL, but how can I get
data in these columns?

Hi arun thats not the real isue..
I have corrected the second code now, it was a typo from my side..
all three tables already have 9 columns selected..
The view created from GTS1 and GTSN1 is constantly changing
There is no way to add column 'I' to any of these above tables
The view is the input to a form..User ticks a tickbox corresponding to records needed by them (These are the columns in the original view mentioned above)..and based on certain logic,only selected columns are now inserted/updated into the output table through the form..this is the table DLC
Now they want to insert a new data(free text) through the form, this field correspond to each record in the form ;this is supposed to be column 'I'(not designed yet)..
this is not there in the original input tables selected for the view...But then I added this column to the output table DLC (Cant think of any other method) so that column I can also get combined in the view.
Now what I want is recreate the view through,
create or replace view statement.
the view should effectively pull data from 3 tables .
The relation between 3 tables :
DLC is a subset of GTS1 and GTSN1
but may also contain data which is not in union of GTS1 and GTSN1
Only field I need from DLC is field 'I', and that too if the data is there in the union of GTS1 and GTSN1

Table Join brings in multiple records

Hi guys,
I have created a table join for 2 HR master tables to get a view.
When i output the view however it brings in multiple records for each employee.
I have set PERNR as the Key field to join the tables but instead of giving me one instance of employee it picks it up 2 records....and in some cases many more, is their a fix for this?
Thanks

Hi,
Try using a combined primary key;
PERNR, BEGDA and ENDDA
There are more primary keys to be combined but try with this 3.

I don't know the table CRM_ORDERM_H however you can link DNOD_NOTIF and DNOD_NOTIF_S
DNOD_NOTIF_S-CLIENT = DNOD_NOTIF-CLIENT

What is the best way to replace the Inline Views for better performance ?

Hi,
I am using Oracle 9i ,
What is the best way to replace the Inline Views for better performance. I see there are lot of performance lacking with Inline views in my queries.
Please suggest.
Raj

WITH plus /*+ MATERIALIZE */ hint can do good to you.
see below the test case.
SQL> create table hx_my_tbl as select level id, 'karthick' name from dual connect by level <= 5
2 /
Table created.
SQL> insert into hx_my_tbl select level id, 'vimal' name from dual connect by level <= 5
2 /
5 rows created.
SQL> create index hx_my_tbl_idx on hx_my_tbl(id)
2 /
Index created.
SQL> commit;
Commit complete.
SQL> exec dbms_stats.gather_table_stats(user,'hx_my_tbl',cascade=>true)
PL/SQL procedure successfully completed.
Now this a normal inline view
SQL> select a.id, b.id, a.name, b.name
2 from (select id, name from hx_my_tbl where id = 1) a,
3 (select id, name from hx_my_tbl where id = 1) b
4 where a.id = b.id
5 and a.name <> b.name
6 /
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=7 Card=2 Bytes=48)
1 0 HASH JOIN (Cost=7 Card=2 Bytes=48)
2 1 TABLE ACCESS (BY INDEX ROWID) OF 'HX_MY_TBL' (TABLE) (Cost=3 Card=2 Bytes=24)
3 2 INDEX (RANGE SCAN) OF 'HX_MY_TBL_IDX' (INDEX) (Cost=1 Card=2)
4 1 TABLE ACCESS (BY INDEX ROWID) OF 'HX_MY_TBL' (TABLE) (Cost=3 Card=2 Bytes=24)
5 4 INDEX (RANGE SCAN) OF 'HX_MY_TBL_IDX' (INDEX) (Cost=1 Card=2)
Now i use the with with the materialize hint
SQL> with my_view as (select /*+ MATERIALIZE */ id, name from hx_my_tbl where id = 1)
2 select a.id, b.id, a.name, b.name
3 from my_view a,
4 my_view b
5 where a.id = b.id
6 and a.name <> b.name
7 /
Execution Plan
0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=8 Card=1 Bytes=46)
1 0 TEMP TABLE TRANSFORMATION
2 1 LOAD AS SELECT
3 2 TABLE ACCESS (BY INDEX ROWID) OF 'HX_MY_TBL' (TABLE) (Cost=3 Card=2 Bytes=24)
4 3 INDEX (RANGE SCAN) OF 'HX_MY_TBL_IDX' (INDEX) (Cost=1 Card=2)
5 1 HASH JOIN (Cost=5 Card=1 Bytes=46)
6 5 VIEW (Cost=2 Card=2 Bytes=46)
7 6 TABLE ACCESS (FULL) OF 'SYS_TEMP_0FD9D6967_3C610F9' (TABLE (TEMP)) (Cost=2 Card=2 Bytes=24)
8 5 VIEW (Cost=2 Card=2 Bytes=46)
9 8 TABLE ACCESS (FULL) OF 'SYS_TEMP_0FD9D6967_3C610F9' (TABLE (TEMP)) (Cost=2 Card=2 Bytes=24)
here you can see the table is accessed only once then only the result set generated by the WITH is accessed.
Thanks,
Karthick.

MVC: Create a view which populates two (or more) joined tables in a single view table

I am beginner in MVC and I would like to create a view which populates two (or more) joined tables in a single view table as described below.
I have two tables:
1 - Bloggers: - bloggerID (int);
                    - bloggerName (string)
2 - Blogs: - blogID (int);
bloggerID (int);
                - blogTitle (string);
                - blogImage (string)
A blogger can have one or more blogs while one blog must be related to only one blogger.
I would like to have a view table on my webpage as the following:
Blogger Name
Blog Title
Blog Image
Noris Gang
Virus
virus.jpg
Noris Gang
Desktops
desktop.jpg
Gauthier
Books
books.png
John Leon
NNNMHJhjdhj
Nmbj.jpg
I'm using MVC 4 (or at least 3).
Thanks for your help.

Hello,
From your description, it is not very clear that what you mean about the View, if it means the View concept in database as SQL Server, your required view should be as below:
Create view
as
Select Bloggers.bloggerName, Bloggers.blogTitle, Bloggers.blogImage
From Bloggers join Blogs on Bloggers.bloggerID = Blogs. bloggerID
If it means the UI view in MVC concept, I suggest you could ask it on the MVC forum:

Materialized View with Join for FAST Refresh

Hi Gurus,
Facing issues in MV with a simple join for FAST Refresh.
2 sample Tables:
1. employee
empid integer PK
empname varchar(50)
deptid integer FK
2. delta_employee
empid integer PK
empname varchar(50)
deptid integer FK
dmlflag varchar(2)
watermark integer
Code is as given below -
CREATE MATERIALIZED VIEW LOG ON work.employee
WITH SEQUENCE,rowid(empid)
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW LOG ON work.delta_employee
WITH SEQUENCE,rowid(empid)
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW work.MVEmployee REFRESH force on
demand with rowid AS
select e.empid,e.empname,e.deptid,d.empid t1
from work.employee e, work.delta_employee d
where e.empid = d.empid;
Able to perform Complete Refresh. Not able to use Fast Refresh for
incremental refresh.
Please help.
Thanks,
J Kumar

Found a solution,
As per oracle documentation rowid fileds should be included in the Select statement. Even though I included the rowid fields, empid in this case it still didnt work.
The implementation of the rowid column should be included with tablename.rowid instead of the tablename.columnname !
Modified script is as given below.
CREATE MATERIALIZED VIEW WORK.MVEMPLOYEE
REFRESH FORCE ON DEMAND
WITH PRIMARY KEY
AS
select e.rowid "empid",d.rowid "t1" ,e.empname,e.deptid
from work.employee e, work.delta_employee d
where e.empid = d.empid;
And It really WORKS

and CAUFV-FTRMI = range of release date in selection screen
and CAUFV-AUFPL = AFVC-AUFPL
and AFVC-ARBID = CRHD-OBJID
and CRHD-OBJTY = A

Strange behaviour of view based on several tables join with union all

Dear fellows we r facing a strange problem we have a view based on several tables joined by union all ,when we issue an ordered query on date,rows returned are unusually different than they should be .
Is oracle has some special behaviour for view based on union all ?
I m using oracle 8.1.6 on windows 2000

Did you ever solve this problem? I have two select statements based on 4 tables and 3 views using about 5 more tables. When I execute each select individually I get exactly what is expected. When I UNION ALL both selects together, I get "no rows returned", however when I UNION them I get exactly what is expected. I should get the same answer for both UNION ALL and UNION. The two select statements are identical, except for one column where I changed the constant to be different. Any thoughts?

How to insert a record for tables joined

Hi,
first of all I've been learning Forms for few days.
I've created a simple form where I report the columns from two tables joining them.
Once I've entered a new list of values in the fields of the form, how can I insert them in the two tables? What I've done, but it doesn't work, is to set "Insert Procedure Name" of the data block = to my procedure compiled in "Program Units" hoping that once pushed the "Execute Query" button in the running form worked, but it didn't work.
Any advice for the better way to how execute an insert in one or more tables with the content of the fields of the form?
My versions are: database 10gXE and forms 10.1.2.0.2
Thanks in advance!

Hi,
Create two data blocks using create data block wizard and join it with a relation. Display the fields you want and form will automatically save your updates in the both tables.
When there is a join you can not update all the fields.

Joins for INV tables R12

Hi,
Could you provide joins for below tables:
mtl_system_items_b
mtl_kanban_cards
mtl_onhand_quantities_detail
MTL_SECONDARY_INVENTORIES
MTL_ITEM_CATEGORIES
MTL_CATEGORY_SETS_TL
MTL_CATEGORIES_B
Thanks

Yes it is kind of limitation in obiee. But there are some solutions which might deviate from best practices.
Sol 1. Snowflake the dimensions in Business Model. Rather than merging both of them into single logical table, separate them into two different logical tables.
Sol 2. For the logical table , have two LTSs. First LTS will have both tables and all columns mapped to both tables. Second LTS will have only main table, Columns belong to that table only mapped. In this way when you selected columns related to first source system will use second LTS which has only only one table.
