OBIEE Subquery Join

Hi All,
I am able to join 2 reports using 'Filter Is Based on Results of Another Analysis' based on e_id and m_timestamp to build report for below query
select a.e_id ,count(distinct a.m_timestamp) from
raw_data a, (
select count(*),e_id,m_timestamp from raw_data
group by e_id,m_timestamp
having count(*) > 1) b
where a.eq_id = b.e_id and a.m_timestamp = b.m_timestamp
group by a.e_id
But i want eliminate join and build a report based on this (to improve performance )
select b.e_id ,count(*) from
select count(*),e_id,m_timestamp from raw_data
group by e_id,m_timestamp
having count(*) > 1) b
group by b.e_id
Which gives same result but with joins eliminated - Can someone help how to implement this in OBIEE 11g ?

Try something like
select e_id ,count(distinct m_timestamp) from
raw_data
having count(1) > 1
group by e_id
If helps mark

OBIEE - Outer Joins

Hi,
I have create a foreign key join between dimension and fact table in the physical layer. Is it possible to create an outer join on the columns, the option (driving and type) in the properties is greyed out and defaults to 'inner'. How can this option be enabled?
Thanks

Hi,
You can create outer joins in Business layer but OBIEE outer joins are not like SQL outer join. They can lead to strange errors.
Its better to do these things in ETL.
Thanks

Why OBIEE always joins all dimensions to the fact?

We have a fact table, which joins 10 dimensions. I have a report that gets data from the fact and only one dimension. However, when i see the physical sql, i see that OBIEE joins all dimensions to the fact, even if I am not selecting any information fro the dimension. Is there any setting to avoid this? eg Fact1, dim1, dim2, dim3. The report has data from fact1 and dim1, but the actual sql joins fact1 with dim1, dim2 and dim3 even if I am not selecting any information from dim2 and dim3 in the report

We do use star model at physical and logical layer. I wonder what change I need to make to avoid this. The fact should not always join all dimensions.

OBIEE - table join across databases

Hi,
I want to join two tables that are in different databases. I want to join these tables on some condition and then be able to see data from both of them in the reports.
Table 1 - columns A1, B1, C1
Table 2 - columns A2, B2, D2
Currently what we tried is
1. create foreign key constraint between the two tables in the physical layer. Map A1 to A2, B1 to B2.
2. create a join of two tables in BMM layer and then port that to presentation layer and then make report using these columns.
OR
try the approach as described on link http://oraclebizint.wordpress.com/2008/03/19/oracle-bi-ee-101332-cross-database-joins/
in both the above mentioned ways, we are not able to see join of two tables. The link mentioned above doesn't work as we tried it multiple times already.
We are able to see individual data from each table, but when we try to see data from them together, we get error.
Can someone help us with this problem.
Please email me on [email protected] if you need more info as i cant paste the confidential data here on the forum.
Thanks in advance,
Amit

We made sure that the datatypes are the same in both tables.
I will explain a bit how we did it.
We have table T1 in database d1, table t2 in database d2. Since datatypes are different there, we actually had to create tables in physical layer and used select query to extract data from databases and get that into those tables in proper format. For example we had to do mapping to make the values of some parameters consistent (like BABY in T1 and CHILD in T2, so we used 'case when T1.parameter1='BABY' then 'CHILD' and so on for other columns).
After that we defined forgein key constraints between these tables, then ported them to BMM layer, then to presentation layer.
We are not getting error in terms on data types. Is there a step by step guide we can follow to get this cross database join.

Amit

Complex query/subquery/join problem

Hi,
i need to retrieve information from our database in one single dataset but i can't get it all together...
Here's the situation:
We have several linked tables:
Workorder (wo_operation)
-woo_key
Workorder_task (wo_task)
-wot_key -> PK
-woo_key -> FK_woo
Workorder_task_labor (wo_task_labor)
-wtl_key -> PK
-wot_key -> FK_wot
-start_time -> essential field
I'm running a query which retrieves records from the Workorder (wo_operation) table like this (this one works nicely, don't mind the other joins):
SELECT
rownum num,
woo.woo_auto_key,
woo.si_number,
apc.application_code,
cmp.company_name,
woo.company_ref_number,
view_wo.serial_number,
view_wo.part_number,
view_wo.description part_description,
wos.description status_description
FROM (((((wo_operation woo INNER JOIN view_spb_wo_maincomponent view_wo ON woo.woo_auto_key = view_wo.woo_auto_key)
LEFT JOIN wo_status wos ON woo.wos_auto_key = wos.wos_auto_key)
INNER JOIN parts_master pnm ON woo.pnm_auto_key = pnm.pnm_auto_key)
INNER JOIN application_codes apc ON pnm.apc_auto_key = apc.apc_auto_key)
INNER JOIN companies cmp ON woo.cmp_auto_key = cmp.cmp_auto_key)
WHERE woo.wos_auto_key IS NULL OR woo.wos_auto_key not IN (2, 10)
Now here's the problem. I need to add one more column which shows the last task (max(wo_task_labor.start_time)) that people have been working on (wo_task.description).
Wo_task is linked to wo_operation on WOO_KEY (many TO one)
Wo_task_labor is linked to Wo_task on WOT_KEY (zero or many TO one)
So I need to find the MAX wo_task_labor.START_TIME and then Select the wo_task.description with that start_time. BUT since the relation is ZERO OR MORE to ONE it could be that there isn't even a START_TIME available for Max() function.......
Is there anybody who could send me in the right direction???

Hmmz ok, I just finished a more readable problem description.. Were you absolutely certain that my problem needs another approach?
here's the problem again:

Does OBIEE has ability to create a single cube from multiple data sources?

Hi all,
Does OBIEE has the ability to create a single cube from multiple sources and does it has the ability to join multiple cubes?
Looking forward to ur reply.

Hi
OBIEE can join multiple data sources to make a single data model, but it's not a cube in the multi-dimensional sense like Essbase or Oracle OLAP.
To be able to join datasources together they need to have a common dimension or FK relationship depending on what the source is and what you want to do with it.

Dimension Table Attributes giving No Fact Table Exists Error

Hi Experts,
My OBIEE version is 11.1.1.6.10. There is a presentation table which has columns coming from multiple logical tables. I'm dragging 2 columns into the report which are coming from 2 logical tables.
The result is displaying. When I checked the query, a fact table is also coming and results are getting effected because of this.
Could anybody let me know if any idea.

Hi SriramKarthik,
Aj (bi007) already gave you the answer on how you can change the implicit fact table, the one you are seeing in your physical query.
I'm just not sure of what is your question: are you surprised to see a fact table is used in the physical SQL and look for a way to avoid it because, as you say, results are impacted by that implicit fact table? You can't get rid of that table, you can only choose it (the implicit one).
OBIEE must join in a way or another your 2 dimensions, and in your BMM these dimensions are joined by a fact table, that's why you see it in your query.

IN clause with more than 1 column, possible?

Hi,
I have an existing (simplied) query:
SELECT sum(bandwidth)
FROM a, b
WHERE a.tag = b.tag AND a.id IN
(SELECT id FROM ...);
If the subquery returns an id, say, twice, I would like the bandwidth to be added twice. E.g. Suppose the query returns (12, 12), then I would like the bandwidth added twice, instead of once as is currently.
Is this not possible for the "IN" clause? So without resorting to stored functions and cursors, etc, is there a pure SQL way to do so?? TIA!

Thanks all for speedy reply and helping me found a solution.
Yes, using a simple subquery / join works just fine.
I had tried that before I post the question but I guess the subquery has to go BEFORE the tables?? E.g. I had this before and it had errors and I gave up:
SELECT sum(bandwidth)
FROM a, b, (SELECT id FROM ...) p
WHERE a.tag = b.tag
AND a.id = p.id;
After your suggestions I went back and switch the order :
SELECT sum(bandwidth)
FROM (SELECT id FROM ...) p, a, b
WHERE a.tag = b.tag
AND a.id = p.id;
and now it works!
Thanks much!

Skipping a table level

Hi, I have these 3 tables (with right FKs and joins) in my Product Dimension:
CITY, SUPPLIER, PRODUCT.
The right level hierarchy should be, from top to leaves: City -> Supplier -> Product
We'd want to build these dimension hierarchy:
City -> Product, but we get this warning in BI Admin (and error then in Answers)
[39008] Logical dimension table CITY has a source CITY that does not join to any fact source.
It can't navigate through the joins, skipping the intermediate table level?
Are we forced to build the entire hierarchy and skip the level (and the table) setting a preferred Drill-Path? (this solution worked)
Thanks in advance!

To resolve this you have two options.
Be sure that you have in the physical layer correct FK join relationships between these tables as follow:
City-<Supplier-<Product
In the BMM make logical table (dimension table) with logical table source Product. Now, in the logical table source Product general tab properties add physical tables and joins (add first Supplier table and join Product>-Supplier, then add City table and join Supplier>-City). Now, drag-drop columns from all tables that you want to use in dimension levels.
Build dimension object with levels, and put columns on each level.
Option one (all three levels):
City level: key use for drilldown checked
Supplier level: key use for drilldown unchecked
Product level: key use for drilldown checked or unchecked
Now you can drilldown in Answers from City to Product, the middle level is not shown, obiee make join through all three tables.
Option two (City and Product levels only):
City level: key use for drilldown checked
Product level: key use for drilldown checked or unchecked
Now you can drilldown in Answers from City to Product, obiee make join through all three tables, because you have define this additional physical tables and joins in logical table source Product.

Are Selects from ( two or more ) Virtual Tables Possible?

Hello.
This is what I mean by a virtual table - and this works in OBIEE -
select
    saw_0, saw_2, saw_3
from
     SELECT
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number saw_0,
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Order_Creation_Date saw_2,
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Order_Closed_Date saw_3
     FROM
        "[Noetix-NoetixGlobalRepository] NoetixViews for Oracle Service"
     WHERE
       "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number BETWEEN '100000' AND '100009'
) t1However, this does not work -
[ Note that each of the nested queries works ok on its own. ]
select
    saw_0, saw_2, saw_3, saw_4
from
     (SELECT
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number saw_0,

     WHERE
       "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number BETWEEN '100000' AND '100009' ) t2
) t3My question is this - is there a syntactic variation on this that does work? Or is it impossible?
Thank you!

Hello, User.
I think what I'm trying to achieve is unclear. Consider first this query -
SELECT
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number saw_0,
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Order_Creation_Date saw_2,
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Order_Closed_Date saw_3
     FROM
        "[Noetix-NoetixGlobalRepository] NoetixViews for Oracle Service"
     WHERE
        "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number BETWEEN '100000' AND '100009'Let's call that the "business result".
What I'm trying to do is get a result set that has 3 rows for every row in the "business result" set. I'm trying to get this by coercing OBIEE to join the business result to an arbitrary 3-row set whose only purpose is to create that cartesian product result.
So I create a second SQL expression -
SELECT
        TOPN("- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number, 3) saw_4,
     FROM
       "[Noetix-NoetixGlobalRepository] NoetixViews for Oracle Service"
     WHERE
       "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number BETWEEN '100000' AND '100009'- which returns 3 rows of anything.
I want to turn this -
1   ABC   20.95
2   DEF   19.95
3   XYZ   24.95Into this -
A 1   ABC   20.95
B 1   ABC   20.95
C 1   ABC   20.95
A 2   DEF   19.95
B 2   DEF   19.95
C 2   DEF   19.95
A 3   XYZ   24.95
B 3   XYZ   24.95
C 3   XYZ   24.95My attempt to force a join fails - and I'm asking if there is a syntax tweak (or another approach entirely) that will do the trick.
Thank you.

Query multiple data sources via keys (federated query)

I have a requirement to fetch data from two different databases, one financial and one operational, to make compound measure (a ratio). I need to fetch a value for the number of calls answered in a call centre from one database (we'll call this "CustomerCare" and the measure "CallsAnswered") I have a good degree of control over this system as it sits in my department so I can add foreign keys into the live tables or add mapping tables, etc. The other measure I need is the wage bill for the same period which comes from a finance database (we'll call this "FinanceMart" and the measure "WageBill").
My problem is that we run this for several joint venture companies and the query needs to take that into account allowing each JV to see only their data. To date all of my tests with OBIEE would issue the following query to both databases...
SELECT Date,CallsAnswered,WageBill FROM <DATABASE> WHERE JointVenture = "JV Motors"
... but that only works if the joint ventures are named the same in both systems and they are not. I need to report by the names in my CustomerCare database (they are familiar to the business) so the only thing I can think to do is to put mapping details (either keys or text values) into my tables and have OBIEE join on those. When I tried this OBIEE failed to issue a query against the FinanceMart as soon as I introduced the JointVenture field but otherwise it works fine when I use either the mapping field or when I use just date.
If anyone can shed some light on this it would be much appreciated.
Thanks in advance.

Both schemas are definitely stars, this example is a slimmed-down version of the real environment (I have many more measures and dimensions) but I only need the one measure from the FinanceMart.
As an example the CustomerCare DB has the following JVs: Star Autos, Fulton Honda, Mortlake Scooters. In the FinanceMart the same three would read: Automotive Sales (UK) Ltd, Jack Fulton & Son Ltd, Peter Evans Motor Company Ltd.
That's why I need some kind of mapping, I just need to know how to configure OBIEE to join on one column but allow you to report by another.

More than one join condition for 2 tables in obiee

Hello,
I am using obiee 11g.
There are 2 tables tableA and tableB where the join condition is like (tableA.col1=tableB.col1) or (tableA.col1 is null and tableB.col1 is null)
where should i do these type of joins.
I tried putting in physcial layer->f(x) but giving error like here only columns an d opertaors are allowed.
Thanks

ok here it goes.
I have a tableA with columns col1(pk),col2 and other columns
I have tableB with columns col1(pk),col2..Only these 2 columns.
Now distinct tableA.col2 values are put in tableB.col2. For those distinct values i have put the tableB.col1 values.
Now tableA.col2 as well as tableB.col2 can be null beacuse there may be null values in tableA.col2.
Now in tableB i have added one more row which has col1 as value and col2 as null.
Now when in physical layer when i do tableA.col2=tableB.col2 i dont get the null values.
What i want is whenever the tableA.col2 and tableB.col2 is null then take tableB.col1 for those vales.
So when i query i do
select * from tableA,tableB where
((tableA.col2=tableB.col2) or (tableA.col2 is null and tableB.col2 is null))
What i want is when i do a join i should be able to give this OR condition in rpd thats it.
because when i do in where clause of content tab it goes like a AND condition and not OR.
Thanks

OBIEE - Null Value in Joins

Hi All,
In OBIEE, How will I handle the null value in join conditions?
I have 2 tables inner joined together in the RPD level. They are User_Profiles table and Parties table.
I am creating a database prompt for a report and in dropdown sql results Iam giving the below query.
SELECT distinct CASE WHEN USER_PROFILES.PAR_ID IS NULL THEN PARTIES.PAR_ID ELSE
USER_PROFILES.PAR_ID END FROM user_profiles,parties WHERE USER_PROFILES.USER_ID='12345' AND parties.par_type = 'ABC' and parties.status = 'N'
Here the PAR_ID is not fetched in the dropdown from PARTIES table . The reason behind this is, when the USER_PROFILES is having PAR_ID as null, it is not able to join with PARTIES table and the dropdown is not populating. It works fine when it fetch from user_profiles table. I believe the issue occurs because of the user_profiles table having null values and not able to fetch from parties table.
Please advice..

Hi All,
I managed to write the query modified like below to handle the null value.
select nvl2(user_profiles.par_id,user_profiles.par_id,parties.par_id) from WFMT_SAINT_PR where user_profiles.user_id= {User()}
and ((user_profiles.par_id is not null and parties.par_id = user_profiles.par_id) OR (user_profiles.par_id is null and parties.par_type = 'MFR' and parties.status='C'))
But when i put this is dashboard prompt sql results for PAR_ID field i get the following error.
Error Generating Drop Down Values

Can you please advice what is wrong here..

Need Help in creating a subquery using JOIN operation

Hi,
I am new to SQL and trying to write a query. Please help me in this.
The Database Schema looks like this:
The database scheme consists of four tables:
Product(maker, model, type)
PC(code, model, speed, ram, hd, cd, price)
Laptop(code, model, speed, ram, hd, screen, price)
Printer(code, model, color, type, price)
The table "Product" includes information about the maker, model number, and type ('PC', 'Laptop', or 'Printer'). It is assumed that model numbers in the Product table are unique for all the makers and product types. Each PC uniquely specifying by a code in the table "PC" is characterized by model (foreign key referencing to Product table), speed (of the processor in MHz), total amount of RAM - ram (in Mb), hard disk drive capacity - hd (in Gb), CD ROM speed - cd (for example, '4x'), and the price. The table "Laptop" is similar to that one of PCs except for the CD ROM speed, which is replaced by the screen size - screen (in inches). For each printer in the table "Printer" it is told whether the printer is color or not (color attribute is 'y' for color printers; otherwise it is 'n'), printer type (laser, jet, or matrix), and the price.
Alternatively you can refer here for the schema (Computer Firm)
http://www.sql-ex.ru/help/select13.php#db_1
Now my query is :
Find the makers of the cheapest color printers.
Result set: maker, price.
and I have written the query as:
SELECT prod.maker, prin.* FROM (SELECT MIN(price) AS price FROM printer WHERE color = 'y') AS prin INNER JOIN (SELECT maker, model FROM product) AS prod ON prin.model = prod.model
Which is giving the error "Invalid column name 'model'.". Please help!
Thanks!
Faaz

Hello,
Your query does not work because your subquery prin does not return a column named model.
Analytical functions like Vivek L suggests are the best way to do this, but this one is a correction of your query and should work too (not tested, unfortunately).
SELECT prod.maker, prin2.*
FROM (SELECT MIN(price) AS min_price FROM printer WHERE color = 'y') AS prin
INNER JOIN (SELECT model, price FROM printer WHERE color='y' ) AS prin2 ON prin.min_price = prin2.price
INNER JOIN (SELECT maker, model FROM product) AS prod ON prin2.model = prod.model;Regards,
Sylvie

How to Do This In a Join Not A Subquery

I have two tables:
USERS
user_id
fname
lname
USER_SITES
user_id
site_id
confirmed
There is a one to many relationship between USERS and USER_SITES (a user can belong to many sites).
I am looking for a query that will return only users who are a member of site_id=2, not site_id=4. The following subquery does the trick:
select * from USERS where user_id in (select user_id from USER_SITES where site_id=2) and user_id not in (select user_id from USER_SITES where site_id=4);
...but I would like to do this using only JOINS (they are generally faster....and also its kind of frustrating me that I cannot figure out how to do it in a join).

Second attempt.
with users as
select 1 as user_id, 'a' as fname, 'b' as lname from dual union all
select 2 as user_id, 'a' as fname, 'b' as lname from dual union all
select 3 as user_id, 'a' as fname, 'b' as lname from dual
user_sites as
select 1 as user_id, 2 as site_id from dual union all
