Extracting Metadata using Common Table Expressions MSSQL

I have been using the below SQL query to extract subsets of the Metadata structure from several dimensions in HFM. The process works well and is simple/quick to develop and incorporate in existing processes. I am curious if anyone else has been using a similar query to extract subsets of HFM Structure directly from HFM or other approaches to extract a subset of HFM Structure.
/*     The query starts with a "Top Parent" and will return all parent/child information below that member. For this example I want all the metadata for the c1 dimension so I am using the top most parent which by default has an ID of -1. You can look up and member's id in the "APP_DIM_Item" table and use that as the "Top Parent" for the query. It is possible to correctly extract only a subset of the overall metadata for each dimension.
WITH dim (ItemID, ParentID, Level)
AS
SELECT
el.ItemID
,el.[ParentID]
,0 AS Level
FROM [<APP>CUSTOMLAYOUT] el
WHERE ParentID = -1 -- The "Top Parent" -1 will extract all metadata
          and lDimID = 1 -- Needed only for the custom dimensions.
UNION ALL
SELECT
     el.ItemID
,el.ParentID
,Level + 1 as Level
FROM [ <APP>_CUSTOM_LAYOUT] el
INNER JOIN dim AS d
ON el.ParentID = d.ItemID
where el.lDimID = 1 -- needed for the custom dimensions
/*     Once the structure is extracted to the temp dim table you can query back and
     join to the Item table to add addtional memeber details. If you leave the query as
     is you will only see the parent/child Unique ID and level informtaion.
-- Parent/Child ID Structure
SELECT * FROM dim
-- Parent/Child Label Structure
Select Dim.ItemID, Dim.ParentID, Dim.Level, Member.Label, Parent.Label
From Dim
inner JOIN <APP>CUSTOMITEM Member -- Member Detail
on Member.ItemID = dim.ItemID AND Member.lDimID = 1
inner JOIN <APP>CUSTOMITEM Parent -- Parent Detail
on Parent.ItemID = dim.ParentID AND Parent.lDimID = 1

i created the stored procedure and tried to use it in universe but i'm not able to.
Request you to help me out with this.

Create a view using common table expressions

I'm having trouble finding out if this is even possible in Oracle.
Here is what I'm trying to accomplish with my view. A subject takes a survey numerous times across numerous dates. Depending on the responses to different questions, that subject is marked as having a set disease or affliction. The view that I'm building collects the necessary answers for each survey into one place (the first common table expression), then in subsequent CTEs, I'm adding the disease classification when the responses to the needed questions match. Sometimes the requirements state that the survey can't already be positive for other diseases, meaning that I need to ultimately discount them when checking subsequent diseases (each disease is built using it's own CTE of which there are 13). I built the query which performs these tasks with no problems. It runs and gives the responses that I'm looking for.
The problem comes into play when I attempt to wrap the existing working query into a create view process. When I add CREATE OR REPLACE VIEW TESTENV.TESTVIEW AS ( and the ending ); after the query, it is giving me the error: ORA-32034: unsupported use of WITH clause.
Am I getting the error simply because I can't put CTE's into views, or is it because the syntax for putting CTEs into Views is different than a normal view build process? Also, in case it makes a difference, the version of Oracle I'm using is: Oracle 10g.
Thank you.

Here is the view that I'm trying to build:

I tried remove the leading and ending parenthesis, and ended up getting the error that it is missing the select keyword. When I take the create view step out of this, the query builds with no problem, so I know that it's not missing a select or that it isn't in the correct place.
Thank you for all your help so far.

Using Common Table Expressions (CTE) in a DSV Named Query

Hi,
I have a scenario where I need to "generate" fact data, so I'm using a CTE to generate the data. For maintainability reasons I have this CTE declared inside a view and in the DSV Named Query I just have a SELECT * FROM FactView.
This works fine as long as the recursion level falls within the default limit of 100. If it does not, I have to specify the maximum recursion level such as:
SELECT *
FROM FactView
OPTION (MAXRECURSION 0)
The problem is I can't specify the Named Query like this. As explained elsewhere my query is embeded as a subquery and the OPTION keyword cannot be used in a subquery.
Is there any other way I can specify the maximum recursion level on a Named Query?

Load your fact table data into staging table and then process fact using direct load from staging table.

Memory usage Common table Expressions

Hope view will use temporary memory while using it.. and
If I use Common table Expressions (with <datsetname> select query )
in stored procedure instead of view will it use the temp memory ?
Many thanks
Kalinga

Why would it be any different? Its still a query. It will use any memory available for sorting
(defined by sort_area_size)
and if it exceeds this it will use the temporary tablespace.
If their is more than one temporary tablespace , it will use the temporary tablespace which that user has been assigned.

Common table expression

Hi,
In DB2, there is a concept called 'common table expressions'.
A common table expression is like a temporary view that is defined and used for the duration of an SQL statement. You can define a common table expression for the SELECT, INSERT, and CREATE VIEW statements. Each common table expression must have a unique name and be defined only once. However, you can reference a common table expression many times in the same SQL statement.
Eg :--
insert into test1 with test_view1(column2) as (select colum1 * 2 from test2) select column2 from test_view1;
Here 'test_view1' is a temporary view created with a select statement. This view has the scope only within this SQL statement. The data inserted into the table 'test1' is selected from the temporary view.
This can be achieved in Oracle by creating views and then using the INSERT .. SELECT statement. But I like to know whether any direct equivalent available for this in Oracle, something like 'INSERT .. WITH <view_name>' as in DB2.
Please advise,
Thanks,
Smitha

Er...you mean like this?

Datatypes in a recursive common table expression

I'm trying to use a (recursive) common table expression to generate a list of dates. The following code is working fine with 11.2
WITH dates ( nr, dt ) AS (
    SELECT 1, DATE '2005-02-01'
    from dual
    UNION ALL
    SELECT d.nr + 1, DATE '2005-02-01' + 1
    FROM dates d
    WHERE d.nr < 30
SELECT dt
FROM dates;But I would like to avoid repeating the start date in the recursive part, and I tried the following:
WITH dates ( nr, dt ) AS (
    SELECT 1, DATE '2005-02-01'
    from dual
    UNION ALL
    SELECT d.nr + 1, d.dt + 1
    FROM dates d
    WHERE d.nr < 30
SELECT dt
FROM dates;But I get the following error: ORA-01790: expression must have same datatype as corresponding expression
Now from my understanding the datatype should be DATE for both parts of the UNION.
I also tried it with d.dt + interval '1' day but that produces the same error message. using to_date() instead of the ANSI date literal does not change it either.
What am I missing here?

What happens to unused common table expressions ,Does this affect in performance or ?

If I write a query with one or more common table expressions to which I
don't actually refer in the query, do they just get pruned off or do
they get executed regardless? how does it affect in performance

seems when the CTE is not refer in the query then statement inside CTE is not executing at all even if it nested CTE, see for your self

Can i use create function for MSSql scalar and table valude function.

Hi,
1) Can i use create function for MSSql scalar and table valued function?
2) How many type of user defined function are there in oracle 11g express?
3) And can i reture any "type" form user defined function?

Q1)That means even if i return predefined types like integer, varchar2 then also PGA is used ?The data type does not determine where the variable is stored. A string (called a varchar2 in Oracle) can be stored in stack space, heap space, on disk, in a memory mapped file, in a shared memory, in an atom table, etc.
It is the who and what is defining and using that string, that determines where and how it is stored.
The Oracle sever supports 2 languages in PL/SQL. The PL (Programming Logic) language is a procedural/declarative language. It is NOT SQL. SQL is integrated with it. The PL/SQL engine uses private process memory (PGA). So PL/SQL variables exist in the PGA (but there are exceptions such as LOBs).
Q2) So please suggest me solution in oracle.Sounds to me you are looking at how to implement a T-SQL style function as an Oracle function, and once implemented, do joins on the function.
Do not use PL/SQL in SQL in place of a SQL select. It is not T-SQL.
One cannot use PL/SQL to create functions along the style of T-SQL, where the function executes a SQL using some conditional logic, and then return as if the function was a native SQL select.
T-SQL is an extension to the SQL language - making it a hybrid and very impure language implementation. PL is based on ADA - part of the Pascal family of languages. The E-SQL (embedded SQL) approach used in languages like C/C++, Cobol and Ada, has been transparently done in PL/SQL. You can write and mix PL code and variables with SQL code. And the PL/SQL engine figures out how to make the call from the PL/SQL engine to the SQL engine.
But PL/SQL is not "part" of the SQL language and does not "extend" the SQL language in a T-SQL fashion.
So you need to check your SQL-Server preconcepts in at the door, as they are not only irrelevant in Oracle, they are WRONG in Oracle.
The correct way in Oracle, in a nutshell - Use the SQL language to do data processing. Use PL/SQL to manage conditional process flow and the handling of errors.

Can some one help me to understand how to use table valued function in OBIEE? I want to use a table valued function (MSSQL function, with some input parameter), in the physical layer to pull the data?
I know for MSSQL Stored Procedure we can write as
EXEC SP_NAME @Parameter = 'VLUEOF(NQ_SESSION.Variablename)'
but now I have a table valued function in the query window I can get the data as
select * from myfunction(parametervalue)
In physical layer of OBIEE I have tried as
select * from myfunction('VLUEOF(NQ_SESSION.Variablename)'), but I'm getting error as the NQ_SESSION variable doesn't have a value , but actually I have initialized the variable but still Im getting error.
Can some one help me to solve this.
Thanks,
Mithun

Need code for Generic Extraction using FM using multiple tables.

Hi Experts,
We are doing a generic functional module extraction based on four tables - say,
Table TT1 u2013 with fields AA, BB.
Table TT2 u2013 with fields CC, DD.
Table TT3 u2013 with fields EE, FF.
Table TT4 u2013 with fields GG, HH.
The value of the field BB = DD.
The value of the field DD = FF.
The value of the field FF = HH.
The key field with which we have to extract data is AA.
We have created a structure for the above tables u2013 say STR containing all the fields from the above tables.
Now as such all the data from the tables is in the internal table ITF.
This data from the internal table is passed to the structure STR.
Somewhere, I think we are making a mistake. I do not know where.
When we check the datasource extraction in RSA3, we find that there is data only from the Table TT1. Data from other tables does not populate in the datasource.
We do not know where we went wrong.
Kindly help us.
Thanking you all in advance.
With Kind Regards,
Shreeem.

Hi,
You will have to use the select query with joins as given in the below example,
SELECT pcarrid pconnid ffldate bbookid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( spfli AS p
            INNER JOIN sflight AS f ON pcarrid = fcarrid AND
                                       pconnid = fconnid    )
            INNER JOIN sbook   AS b ON bcarrid = fcarrid AND
                                       bconnid = fconnid AND
                                       bfldate = ffldate     )
WHERE p~cityfrom = 'FRANKFURT' AND
        p~cityto   = 'NEW YORK' AND
        fseatsmax > fseatsocc.
But I would suggest you to better create a Data base View with all the required tables and then use that view for data selection in your FM.

Loading metadata into EPMA applications using Interface tables-Automation

Hi,
I am loading the metadata into epma applications using interface tables as ODI dont perit to load metadata into epma applications. Is there any way of using ODI and interface tables together to load the metadata
This process also need to be automated.

Hi,
It is certainly possible and has be done, though there is not anything available that will do it for you, you will have to put in some effort learning the structure of the interface tables, then build interfaces and then a package in ODI to streamline the process.
Cheers

Extracting data from multiple tables using DB connect

Hi,
I am having different tables which are having the same structure in oracle database but there names are different.Now i have only one datasource at BI side.This datasource shld extract data from the tables dynamically.How can i do it using DB Connect .
Thnxs

ahh I see - problem as you said then is if you then take on a new location!
I would then put into the source system a table identifier and create a view across all the tables
Then dbconnect from the view and use the selection parameter of table parameter if you wanted one infopackage per "location"
If you do need to have a new table in the source then just expand the view and create a new ipak
hence NO bw changes required that need a dev-q-p transport - just the ipak in prod and it;s the source systems problem to add the extra table to the view

Extract Data Using SQL Expression

Hello, I've created a staging table and just realized that I need some new extra fields.
Should I create them in the stage or in the target table?
I want to use the SQL expression COUNT so to fill these new fields with edited source data,
but don't know exactly how to do it. I am a bit amateur.
Thank you.

I' ve just realized that I am reading your book! Oracle Warehouse Builder 11gR2: Getting Started 2011.
What If I need the rest of the fields not to be changed? Fields like Name or whatever.I can't figure it out. Thanks again.
For example, I have these two fields Name and Date and I want to use the count expression through the aggregation operator for the Date field and create a new field Quantity to store the reaults. But I need the field Name to remain intact.
How can I manage this? Thank you.
