Handling table name changes

Hi,
Because of a change in naming convention, all our source table names are changing (only the prefix: The rest of the name and the table structures will remain the same). We already have developed a significant number of OWB mappings based on the old naming convention. What is the OWB equivalent of doing a global search replace of table names ? Is there a script available for doing this ?
Thanks in advance.
Regards,
Biswa.

The name changing part should be relatively simple to handle. I have included a script that should do the renaming with the prefix 'WH_'. The reconcile will have to be done by you. The script should go something like this (please test your scripts in a test environment as I will not provide support for this).

SAP BW structure/table name change issue with BODS Jobs promotion

Dear All, One of my client has issue with promotion of BODS jobs from one environment to another. They move SAP BW projects/tables along with BODS jobs (separately) from DEV to QA to Prod.
In SAP-BW the structures and tables get a different postfix when they are transported to the next environment. The promotion in SAP-BW (transport) is an automated process and it is the BW deployment mechanism that causes the postfixes to change. As a result with the transport from Dev to QA in SAP-BW we end up with table name changes (be they only suffixes), but this does mean that when we deploy our Data Services jobs we immediately have to change them for the target environments.
Please let me know if someone has deployed some solution for this.
Thanks

This is an issue with SAP BW promotion process. SAP BASIS team should not turn on setting to suffix systemid with the table names during promotion.
Thanks,

How Discoverer Reports cope with table name changes

I want to change the name of an oracle table that is queried by a number of Discoverer reports owned by various users.
I have been told that Discoverer might have the smarts to handle this without manual intervention of users having to open their reports and repoint them to the new tablename. Would someone be able to enlighten me?

Thanks Guys for help.
Additionally I'd like to add for the purpose of the name change is business driven and therefore it is important that business (report writers) see the new name so.....
For each simple folder in the EUL there are there 3 attributes you need to be aware of:
(1) Folder Name (the name as seen in Discoverer)
(2) Identifier
(3) Physical Database Object name
(1) and (2) are used by a Disco workbook to resolve back to the physical object name.
Therefore, you can change either (1) or (2) [but not both] and still have the workbook resolving back to the physical object name on the folder (ie (3)).
In summation, I changed (1) and (3) while leaving (2) unchanged to resolve the whole glorious mess....

Database "TABLE" name change is NOT reflecting on Designer Security

Hi all members,
version: BOXI 3.1
I have change the table name in my Database for some particular reason.
After changing the name from "A_Table" to "B_Table" it is updating the objects "select" information correctly by itslef. BUT for security in (Manage Access Rights) old Table name is showing.
Manaul correction is the only way for it? Can this be updated automatically.
What is the way to achieve it through SDK.
Kindly any member guide me.
I have number of tables to change and each have number of securities applied in universe.
Thanks in advance
Regards,
Izhar

Universe access security is encapsulated separate from the Universe unv itself.
Rather, it's a SI_KIND='Overload' InfoObject instance, accessible using the BusinessObjects Enterprise SDK.

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.
Suresh

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

Table Name-Changes in SO

Dear All,
As we all know that any changes done in Sales order, we can see them by going to Va02-->Environment -->Changes...
According to our client's requirement, we need to generate a report which can show all the changes done to a SO. For this I want to know the TABLE name in which the changes that we have done to the SO are going to be stored.(Kindly let me know if there is any Standard Report exists in SAP R/3 for this kind of requirement)
Points assured for Helpful answers

Hi,

Admin advice: table name changes, etc.

Our Discoverer system is still evolving and there are instances when a change, say to a table name that users have build workbooks on, is required. Is there a way to scan the workbooks and make this change for the users?

Hi
No, this is not possible. You have to be extremely careful making changes to an EUL after workbooks exist. Mind you, just because you change a table name does not mean you need to change the folder name or identifier. You can change the table pointer without making any other changes, so long that is that the new table has the same data items and data types as the original. If it doesn't you could be in deep trouble.
As a note, you do need to make sure that you correctly maintain both the folder name and the folder identifier and not allow these to take generic names and defaults such as NEWFOLDER1 etc. This is bad EUL design and you will end up with issues in the future.
If you have a copy of my Oracle Discoverer 10g Handbook, available from good bookstores or amazon.com via http://learndiscoverer.com/books/books.htm, take a look at chapters 17 and 18 which describe in detail how to get going in and maintain business areas. In particular, pages 640 and 641 cover folder management and discuss the impact of changing names and / or identifiers.
I hope this helps

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.

Updated Table Name Changes Applescript Operation in Numbers 3.5

I've been using Applescript in Numbers for some time to copy/paste data (set cell values) from one sheet table to another sheet table.
My original script was heavily cribbed from something Yvan Koenig had posted 2-3 years ago.
I recently updated to Yosemite and Numbers 3.5 after testing to ensure my original script remained functional (and it did).
I subsequently updated my source data table by duplicating my old table and editing this new source.
I then updated my Applescript to to reference the new source table.
Testing yielded a good functional result, but Numbers changed its behavior by displaying its work while setting values in the target sheet table.
This obviously slows the script down and adds measurable processing time given the amount of data being moved.
Does anyone know how I can prevent this behavior from occurring?
I don't believe I changed anything material in my original script so I'm really not sure why Numbers changed its behavior.
I have included my script below. Thanks very much for any help!

Here is a simple example that copies values from a source row 3 in Table 1 to a target row 5 in Table 2.
On my aging MBA it was very fast (about a second) with 150 columns.
In addition to speed, an advantage of this approach is that you don't have to code table dimensions; the target table will expand automatically if needed.
Save the script in a script folder (in my case ~/Library/Scripts/Applications/Numbers) and run it from there by choosing it from the script menu. (Running it from Script Editor will paste the values into Script Editor instead of into Numbers as you want).
If keeping the original number format is important, substitute 'formatted value' for 'value' in the script.

Have tables names changed from CF6/7 to CF 8/9?

<<Edit>>I might have just answered my question, sort of. I had already exported the data from the hosted SQL 2000 DB to my local SQL 2000 DB and then backed up and restored it to an empty DB in SQL 2008 Express. The tables have the dbo. prefix instead of the "xx." prefix in the other DB which went from SQL 2000 to SQL 2008. The site runs with the dbo. prefix. Any links to articles/videos/summaries of simple differences between version still appreciated."<</Edit>>
I built a CF6/7 based site about 5 years ago and I'm trying to move it to the current versions of MSSQL (2008R2 Express) and CF9. I believe the SQL DB is fine, I have setup the site on the local server, and am getting the following error when trying to view a page that access the DB.
[Macromedia][SQLServer JDBC Driver][SQLServer]Invalid object name 'client_info'.
I exported the DB data from the live DB server into my local SQL 2008 Express and tables now have names like "xx.client_info" Is it correct to assume that this is a new naming convention so that you can access easily access tables in multiple DBs? Would I simply need to rename the tables to exclude the "xx." at the begining? Or would it be advised to export the data into SQL 2000 and then backup/restore the DB to SQL 2008 Express?
Thanks for any help, and if there's a video or link to simple differences/improvements in CF from 6/7 to 8/9 any link would be greatly appreciated.

It's not CF-related, it's a SQLServer thing. In SQL 2008 they introduced the concept of Schemas, which I think is what you're seeing here. Rather than dbo.tablename, you now have schema.tablename.
I don't know the details to be honest, but that's what you need to be looking at.

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 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....

end loop;
I have tried the execute immediate command but the sql was loo long.
Anybody has any idea? Thanks in advance.

I have tried the execute immediate command but the
sql was loo long.So you already know that if you have "dynamic" tables then you need "dynamic" sql.
It's at this point you should ask yourself if "dynamic" tables are really the best solution for your database design.
Clearly, any application written against the database needs to know what tables it is accessing and, likewise, this should make you think that it's perhaps a good idea that the tables are known at the time the application is designed.
What is your requirement for having tables with similar names but different suffix's?
The classic design fault is people who create seperate tables for certain time periods i.e. each month a new table is created for that month of that year. This of course leads to the problem of dynamic tables and dynamic queries.
In such a situation, the better design would be one of the following...
a) if you have the partitioning option on your oracle database, create your table with partitions for the required sub sets of data. Partitions can be added, truncated or removed without the table name changing. They can also help the queries to perform faster as the optimiser will be able to determine what partitions it needs to access to get the data.
b) if you don't have partitioning then consider including relevant columns in the table to provide the relevant sectioning of data. With suitable indexes this can be just as performant, even with a lot of data.

Dynamically changing name of JPA Table via @Table(name=..)

In my application I need to change dynamically the name of a table to create, which is annotated
via @Table(name="MyTable")
The problem is that the application handled all tables with an internal prefix so that MyTable would
be changed to something like "application1_MyTable". In xml mappings it is possible by injecting
a modified version of the xml mapping content, in plain jdbc only dynamic statements must be used
for this kind of renaming. But how can I achive this with (immutable) annotations?

Sounds like a very bad design.
I'd be shocked if you could manage to give a good, coherent reason beyond "because I said so".There is always a trap which can force you to support a bad design despite better knowledge:Or, if you're really smart, refactor the trap out of existence.
legacy issues. Depending on the project an old chunk of application code lets you only change
design to a certain degree (based on time, effort, dependencies to other systems). In my case
there is a need to keep the distinction of tables by a dynamic prefix.I'll agree that I might not understand fully. Why not temporary tables or materialized views? Is your idea the only way to accomplish this?

How to dynamically change the table name inside a view

Hi All,
create table t_auto_feeds
id number,
table_name vachar2(100));
insert into t_auto_feeds values(1,'T_FEED_POSITIONS');
insert into t_auto_feeds values(2,'T_KAP_MTM');
assume there are 100 records on id=1 in T_FEED_POSITIONS and 100 records of id=2 in T_KAP_MTM (id 1 is present only in t_feed_positions & id 2 is present only in t_kap_mtm)
i need to create a view such that it needs to give the count of records based on the id
create or replace view aa_view as
select count(*), id from t_feed_position group by id
union
select count(*), id from t_kap_mtm group by id;
I am getting a proper result when i query the view like select * from aa_view where id=1 but will the other union query seems to be a overhead?. I am having 10 such tables configured for different id in t_auto_feeds.so do i need to put 10 unions or is there a better way to handle this stuff.
I know i can use a PLSQL block and dynamically build view structure, the problem is the view itself is configured in a table , so i cant write a proc for this.. can this aa_view be modified such that it queries only the table(using the t_auto_feeds ) which matches the id rather than the entire list.
Kindly help me in this regard and let me know in case u need any further information from my side.

Yes - you need 10 unions
Yes - there is a better way so that only one of the 10 queries does anything.
You can use SYS_CONTEXT to control the query selection.
Here is an example of using SYS_CONTEXT. Try this code in the SCOTT schema.
create or replace context VIEW_CTX using SET_VIEW_FLAG;
create or replace procedure SET_VIEW_FLAG ( p_table_name in varchar2 default 'EMP')
as
begin
dbms_session.set_context( 'VIEW_CTX', 'TABLE_NAME', upper(p_table_name));
end;
select * from emp where 'EMP' = sys_context( 'VIEW_CTX', 'TABLE_NAME' );
select * from emp1 where 'EMP1' = sys_context( 'VIEW_CTX', 'TABLE_NAME' );
select * from emp2 where 'EMP2' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
exec set_view_flag( p_table_name => 'EMP' );
exec set_view_flag( p_table_name => 'EMP1' );
exec set_view_flag( p_table_name => 'EMP2');
SELECT sys_context( 'VIEW_CTX', 'TABLE_NAME' ) FROM DUAL
CREATE VIEW THREE_TABLE_EMP_VIEW AS
select * from emp where 'EMP' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
union all
select * from emp1 where 'EMP1' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
union all
select * from emp2 where 'EMP2' = sys_context( 'VIEW_CTX', 'TABLE_NAME' )
SELECT * FROM THREE_TABLE_EMP_VIEWNote that you set the context for the table you want. This doesn't have to be a table name it could just be flag value
-- use the emp table
exec set_view_flag( p_table_name => 'EMP' );
-- ue the emp1 table
exec set_view_flag( p_table_name => 'EMP1' );
-- use the emp2 table
exec set_view_flag( p_table_name => 'EMP2');
