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:

Dynamic table name, how to query?

Hi!
There is a table name that is decided dynamically. the name is:
someNameYYY where YYY denotes the client number.
I get the client number by sy-mandt and concatenate it with someNameYYY to lc_table_name but then comes the problem:
I cannot do
SELECT *
FROM lc_table_name
because I get compiler error "lc_table_name" is not defined in ABAP dictionary.
How do I query a table with the name decided dynamically?
regards
Baran

(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.
Can anybody solve my problem.
Thanks in advance
Mustafa

Table name change in procedure dynamically

create table tab1(x number);
create table dynamic_table (x number);
insert into tab1 values (1);
insert into dynamic_table values (1);
commit;
create procedure proc1
is
v_x number;
begin
execute immediate 'create table mytab
as select tab1.*
from tab1, tabc
where tab1.x = dynamic_table.x';
end;
begin
proc1;
end;
/dynamic_table --> should be dynamically replaced in the procedure
There are two more tables in this scenario - tabe and tabf, In the above procedure, I have to dynamically replace dynamic_table first with tabe, call it, then then replace with tabf and execute procedure again
Is there a way I can do that ? any dynamic sql that will prompt me to call proc1 twice, 1st time replace dynamic_table with tabe, then with tabf
the structure of tabe and tabf is the same, I am currently passing a parameter to the procedure and replacing dynamic_table with the input parameter, and then
calling the procedure twice by passing the table names, wanted to follow a better approach
Currently, I am doing somethig like this:
create procedure proc1 (i_param in varchar2)
is
v_x number;
begin
execute immediate 'create table mytab
as select tab1.*
from tab1, tabc
where tab1.x = i_param.x';
end;
begin
proc1('tabe');
proc1('tabf');
end;
/

Why are you trying to do this?
Good database design practice means that you don't create tables dynamically within your code.
Why do you have tables of the same structure with different names?
Dynamic table names are not a good idea because it means all your code has to be dynamic.
So whilst it's perfectly possible to do what you are asking, showing you how to do it would be like me showing you how to fly a plane into the ground, i.e. not something that's clever or wise.
So, better you explain what problem you are trying to solve rather than ask us how to improve on the poor code you are already trying to do.

Dynamic table name in an inner join - select statement

Hi,
Please can you let me know if is possible to use a Dynamic table name in an inner join?
Something like the statement below? (It works in a simple select statement but not in an inner join)
SELECT *
     INTO CORRESPONDING FIELDS OF <t_itab>
      FROM <Dynamic table name> INNER JOIN pa0050 ON
      ( <Dynamic table name>pernr = pa0050pernr )
       WHERE <Dynamic table name>~pernr = it_pernr-l_pernr
       AND pa0050~bdegr = f_bdegr.
Any help would be apprecited very much.
Thanks & Regards.

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,

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>

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.

Table name changed in Reports 3.0

My DBA asked me to change the table name from SA_AWARDS to SAFETY_AWARDS.
I had already developed a report using table name SA_AWARDS.
When I change the table name in my report to SAFETY_AWARDS, I get compilation errors.
How can I fix it ?
Thanks.

Hi
As i understand your problem , you have changed the table name in the query wizard and then tried to compile and it is giving errors ....
well anytime you modify the sql (even add a space) the column names are renamed ... ie if you originaly had column Customer_name it would be renamed as customer_name1 ....
now if in the original report you are using the columns for any computation etc it will not find the old column and will give compilaiton errors .... one way is to change the column names back to original names ... or better modify the sql once more by adding space and you will get back the original names most of the times .....
the best way to avoid this is give alias name in the sql first time around , so it dosnt create problems ....
once you take care of this i think your problem should be solved .....
if not do let me know in more detail

*Dynamic* Table Name in From Clause with input from cursor

Hello
I have a cursor say...
select table_name from dba_tables where <blah>
The result is
row1:: emp
rwo2:: emp_1 ---> Both the tables have same structure and entirely different data... please dont ask why... that's the way it is and we cant change it..
Now we need to run an Insert...
insert into tableX (col1,col2,...) select a,b,... from <o/p of the cursor> where <blah> ...
Note: The table name changes and it the cursor can o/p emp,emp_a and emp_b.
Am looking to do it parallel instead of doing it serially and with best performance ....no sql injection issues.
By parallel i mean
insert into tableX (col1,col2,...) select a,b,... from emp where <blah>
and insert into tableX (col1,col2,...) select a,b,... from emp_1 where <blah> statements to fire parallel/at the same time to the database. If you can share procedure if you guys already have with you.. is really appreciated
Thanks a lot for your time....

Hello thanks for your time..
I tried to implement the chunk by sql parallel execution approach and it took 3.1 seconds to complete.. while the SP took around 0.042 seconds and the parallel process didn't throwed any errors and it didn't insert any data either... I am not sure what I am doing wrong... can you please let me know your thoughts...

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;
--Just a test proc.
