How to pass dynamically table name in my cursor declaration

Hi:
I am new. could you please let me know how to pass a table name dynamically in my cursor declaration? for instance I am declaring the following cursor in my pl/sql procedure:

Begin
query_str := 'Select empno, ename, sal from emp_' || month ||'_'||year
|| ' where empno = :id';
open c for query_str using emp_number;
loop
fetch c into emp_number, name, salary;

Urgent Help on Dynamic Table name change in query !!!!!!!!

Hi Everyone,
I'm having a repeating frame which displays table_name, count_validate and count_error. How can i dynamically change my table_name in formula column apllied on count_validate and count_error. I can do this with multiple elsif statement, which makes my report slow at runtime. Select statement is same , only change is table_name ?
Kindly let me know......

Try to use dynamic ref cursors (defined in a database package).
This is not exactly what you need, but see:

How to set dynamic host name in the URL of a URL iView?

Hello,
I am using a standard URL iView that points to some J2EE app I've written and deployed on the same server.
I would like to set the host name to be a dynamic one, this way I won't need to change the iView URL when transporting it from one portal to another. As far as I know the system for a URL iView only controls authorizations but cannot replace the full URL set in the iView.
Any idea who can this be achieved?
Roy

Hi Mrityunjay,
forced URL at runtime will require me to call the URL iView from another iView that I will need to code (setting the URL in the Request object). If I did all this I might as well call it from this iView already.
I would like to do it with no further developments. I would have thought that SAP has constants that can be plugged in the URL for this type of thing, i.e. $hostname...
Rgds,
Roy

How to know primary key column name form a table name in sql query

Suppose I only know the table name. How to get its primary key column name from the table name?
Thanks

Views don't have primary keys though their underlying tables might. You'd need to pick apart the view to determine where it's columns are coming from.
You can select the text of the view in question from user_views.

How to set dynamic IN clause in VO Query

Hi ADFExperts,
I have a requirement like I have a viewObject
Let say "Select * from contact"   Result of this query is 20 lakhs records
My Requirement,
I have to apply "IN" clause in that view object so It will bring only required row.
E.g Select * from contact where First_name IN : bindName;
In bindName param of string type I am passing "('James','John')"
and I am executing VO.
But it is not returning the result.
Please help.

Oracle db doesn't support construction: where something in :bind_var.
You can follow one of these approaches:
Decompiling ADF Binaries: Using oracle.jbo.domain.Array with ViewCriteria
Decompiling ADF Binaries: Using bind variable for the SQL statements with IN clause
Or try pure sql solution(I hope that [code] tag works on this new forum ):
[code]
select *
from contact
where first_name in (select substr(list,
                                                  instr(list, ',', 1, level) + 1,
                                                  instr(list, ',', 1, level+1) - instr(list, ',', 1, level) - 1)
                                from (select ','||:bindName||',' list from dual)
                               connect by level <= length(:bindName) - length(replace(:bindName,',',''))+1)
[/code]
So you can pass: James,John as value to :bindName variable

) as

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?

What you are asking can be done by REF_CURSOR;
look this example and try your self the rest:

How to set dynamic name of the mail attachment according to source file ?

Hi,gurus:
Our scenario is like below:
Sending files from an FTP server to another FTP server without using the integraiton repositary,and the file name is not changed .Now, we want to also send the file to some with by mail adapter.The scenario now works by using two business services in receiver determination.But the name of the attachment is "untitled.xml".We know how to set the file name staticly,but how to set the name dynamicly according to the source file name ?
I have checked miachel's blog "XI: Dynamic name in the mail attachment - pseudo "variable substitution"(/people/michal.krawczyk2/blog/2006/02/23/xi-dynamic-name-in-the-mail-attachment--pseudo-variable-substitution),but how can I get the source file name?
And another question:Must we restart the adapter or j2ee engine to make the user defined module work?

Hi,

How to replace a table name with an item value in report region SQL query?

I've got a SQL query in a report region that goes like this:
SELECT :P30_HIDDEN FROM v_dms_dataset
GROUP BY :P30_HIDDEN
P30_HIDDEN is populated from a textfield input. Why doesn't this work, and is there a way to achieve what I'm trying to do here? I really need the ability to dynamically generate SQL queries in this way.

Ben - you could either:
1. case when :P30_HIDDEN = 'COL1' then col1 else ... end
in order to determine which column to select (only really useful if you have a small number of predetermined columns to select from), or
2. generate the SQL dynamically.
Set the report region to SQL Query (PL/SQL function body returning SQL query), then have something like:
declare
l_sql VARCHAR2(4000);
begin
l_sql := 'SELECT ' || :P30_HIDDEN || ' FROM v_dms_dataset
GROUP BY ' || :P30_HIDDEN;
return l_sql;
exception
etc.
end;

I only started about 6 weeks ago, with no tutorials and learning it on the fly; Same here.. only my introduction was to a 12 node Oracle OPS cluster all those years ago.. and required a whole new mind set after using SQL-Server extensively. But it was fun. Still is. :-)
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,

How to create Dynamic Table Control

Hi
How to create Dynamic Table control , The field names and values to be displayed in table control are to be fetched from Add-on Tables.
Regards
Prasath

Hi Jonathan,
Actually the columns to be displayed are not constant . It will be increased based on the database values, Anyhow it will not exceed 100.
Please confirm my understanding.
1. In this case I have to create 100 custom columns and make it visible / invisible based on my requirement and I can set the title at runtime.
2. How can i assosicate / reassociate the datadictionary reference for the columns that i use. Because I need to show the search help values for the
dynamic columns.
Your opinion on this will be helpful.
