Data model with a dynamic table name

Hi,
I have report requirement, where in the table name in the data model query is unknown.So I use lexical parameter like " select * from &P_TABLE_NAME". This dynamic table is created and data populated in the before report trigger and table name is assigned to P_TABLE_NAME. The parameter P_TABLE_NAME has to be assigned an initial value otherwise the report errors with 'invalid table name' error. So I give a dummy table say 'DUMMY' as the initial value which has the same structure (with no data ) as the table that is being created in the before report trigger.
The problem is that the data model query is being parsed ( and maybe executed ) even before the 'before report' trigger is run. As a result, the report o/p is empty, since the query used the DUMMY table for execution. But after the report completes, I can see the dynamic table being created with data.
Question: Why is the before report trigger getting executed after the datamodel query is parsed and executed.
Regards,
Suresh

Hi....
yes, these are the settings I have:
server folder: /Applications/MAMP/htdocs/dwphpelclasico
web url: http://localhost/dwphpelclasico/
They should be correct. But I still get the message:
Warning: require_once(Connections/elclasico.php) [function.require-once]: failed to open stream: No such file or directory in /Applications/MAMP/htdocs/dwphpelclasico/list.php on line 1
Could it be something with list.php?
This is a new file I created to display my tableand where I am inserted the record set.
thanks

Problem with Dynamic Table Name

Hello all,
I am having trouble using a dynamic table name. I have the following code.....
declare l_cur sys_refcursor;
l_ID int;
l_tableName varchar(30);
BEGIN
open l_cur for
select hkc.ColumnID, mapping from &HKAPPDB_Schema_Name..doctablemapping ddm
inner join &HKDB_Schema_Name..HKColumns hkc on hkc.doctablemappingid = ddm.id
where ddm.id > 0;
LOOP
     FETCH l_cur into l_ID, l_tableName;
     EXIT WHEN l_cur%notfound;
     -- update missing VerbID in DocumentDocMapping table
     UPDATE &HKAPPDB_Schema_Name..IndexedDocument
     SET VerbID = (SELECT t.VerbID
                         FROM (SELECT DocRef, VerbID, DateUpdated
                              FROM &HKAPPDB_Schema_Name..l_tableName dd        - this is where the dynamic table name is used
                              WHERE dd.VerbID is not NULL))
     WHERE HKColumnID = l_ID AND VerbID is NULL;
END loop;
end;
/When I try to execute this i get an error
ORA-00942: table or view does not exist
What am I doing wrong?

but thats what you get when a company throws you in at the deep end with a ridiculous time constraint to migrate a whole MSSQL DB.Migrating SQL-Server to Oracle is not a simple thing. A lot of best practices in SQL-Server are absolutely worse practices in Oracle - they are that different. Simple example is lock escalation - an issue in SQL-Server. In Oracle, the concept of a lock being escalated into a page lock simply does not exist.
In terms of getting the migration done as quickly and painlessly as possible I try to reuse all the logic as it appears in the MSSQL code - in this case it was using dynamic table names. I do not doubt that i am probably shooting myself in the foot in the long run.....As long as you do not splatter too much blood on us here.. not a problem :D
Seriously though - just keep in mind that what works in SQL-Server may not work as well (or even at all) in Oracle. So do not hesitate to refactor (from design to code to SQL) mercilessly when you think it is warranted.

Passing dynamic table name in ADO. net destination

I am new to SSIS and I have a requirement where i need to pass dynamic table name in ADO .net destination .
My package contains an "Execute Sql task" in the control flow which computes the destination table name to be provided at run time and stores it in a variable expression
"@[User::Table_name]"(which has a scope of full package).
Now, the problem I'm facing right now is that , I am unable to use this variable expression in the ADO .Net Destination .
I need to pass this variable expression as the table name in ado .net destination.
But, whenever I use this variable in place as the table name I keep on getting this error and my package fails:-
[ADO NET Destination [403]] Error: The Table or View name is not expected. \n\t If you are quoting the table name, please use the prefix " and the suffix " of your selected data provider for quotation. \n\t If you are using multipart name,
please use at most three parts for the table name.
Although ,I am able to run my package when i am providing the existing(static) table name.So there is nothing wrong with the package.
Tried a lot of things still not working..Please help...

I am having the result stored in the variable expression . I just need a way to be able to use it as the Destination table in ADO .net Destination.
I am not sure if this will work for you, but I am able to store the table name in variable and use it dynamically (via data flow task expression property ) as shown.
Thanks, hsbal
Hi Adeep,
Based on my further research, just as hsbal said, we can set a variable as ADO.NET Destination table via Expressions property in Data Flow Task.
If there are any other questions, please feel free to ask.
Thanks,

(Urgent) Dynamic Table Name

Hi Fellows,
Can I use dynamic table name in a loop? I have a problem that I want to use variable table in a cursor for example
procedure check_rows as
cursor c1 is
select view_name
from user_views;
v_count number;
v_view_name varchar2(35);
begin
for i in c1 loop
select count(*)
into v_count
from i.view_name;
if v_count = 0 THEN
dbms_output.put_line ('The View '| |i.view_name| |' has no rows');
end if;
end loop;
end;
but i receive a message
i.view_name must a name of a table to which the user has access.

Dynamic table name - error

After run (or test) of procedure
create or replace procedure tmp_select_dymanic
( AInTable IN VARCHAR2,
ACount OUT NUMBER
) as
begin
EXECUTE IMMEDIATE 'BEGIN SELECT count(*) INTO :Count FROM :InTable END;'
USING ACount, AInTable;
end tmp_select_dymanic;
error message: invalid table name.
I know the table exists and contains data. I can make SELECT in SQL (not dynamic).
What a reason for error? May be privileges in database? But i make SELECT on my own table?
How can i set dynamic table name in other way?
My Oracle Version 10g.

What you are asking can be done by REF_CURSOR;
look this example and try your self the rest:
CREATE OR REPLACE PROCEDURE insert_to_table_dinamic (
   table1   IN   VARCHAR2,
   table2   IN   VARCHAR2
AS
   rc         sys_refcursor;
   v_sql      VARCHAR2 (2000);
   v_deptno   NUMBER;
BEGIN
   v_sql :=
         'SELECT DEPTNO FROM '
      || table1
      || ' WHERE ROWNUM = 1 AND DEPTNO IS NOT NULL';
   OPEN rc FOR v_sql;
   LOOP
      FETCH rc
       INTO v_deptno;
      EXIT WHEN rc%NOTFOUND;
      v_sql :=
            'UPDATE '
         || table2
         || ' SET DEPTNO = '
         || v_deptno
         || ' WHERE DEPTNO IS NULL';
      EXECUTE IMMEDIATE v_sql;
   END LOOP;
EXCEPTION
   WHEN OTHERS
   THEN
      DBMS_OUTPUT.put_line (SQLCODE || SQLERRM);
END insert_to_table_dinamic;when i give DEPT , EMP as my 2 parameters above code will set the deptno in EMP table where deptno is null;

Dynamic table name from Arguments in cfquery /

I'm trying to use dynamic table names in a cfc but seem to
have hit upon a wall as my calling methods from flash keep hitting
my _error methods - Code attached to show what I'm trying to
achieve; if anyone can give me some pointers it would be a great
help. I've seen numerous by using the Form with the arguments but
this is coming into a gateway used by a flash component and doesn't
work no matter how much I fiddle the code.
Thanks in advance

There was a time when I needed a dynamic query such as this.
BUT, it is very dangerous, which is why I took a few steps to make
it more secure.
1. Always use cfqueryparam and strict datatyping
2. Use listFindNoCase for known table names in the database
e.g
<cfset variables.tableNames =
"items,products,categories,blog" />
<cfif
listContainsNoCase(variables.tableNames,lCase(trim(arguments.tableName)),",")>
query here
<cfelse>
Error: Unknown table requested
</cfif>

Model with 2 fact tables

Hi all,
i have a model with two fact tables, both of them containing these columns:
- some measures
- foreign keys for dimensional tables
- column year
- column month
I have to build a model with both of these two tables, including a unique time dimension. Do anyone knows how i can do to make a unique dimension for both of the tables?
Thanks in advance,
Regards

A time dimension (or date dimension for that matter) are quite independent and you can find N good generic time/date dim structures out there (with proper Y/M/DAGO keys, calendar vs fiscal rollups etc etc).
But if you only want to create a single common time/date dim based on what you have in your facts, you can just follow (as a quick win before thinking about how to structure a physical time/date dim) Stewarts basic example here:
http://www.rittmanmead.com/2012/12/obiee-transactional4/

How to share JHS BC4J data model with JClient application ?

In our project, some application system using JHS Struts/JSP solution but others which need rich UI application prepare to adapt JClient solution, so whether we can share JHS BC4J data model with JClient application ?

Ting Rung,
The JClient application will communicate with your application module. So all logic in you app module, EO's and VO's can be resued by JClient. Logic in Jheadstart handlers cannot be reused.
