Hi Ashu,
You write the structure name in se11
after selecting the database table radio button
click on the where used list button in the application tool bar.
You will find the table name if it is used else where.

How to find out which queries are being used ?

We have a number of InfoSet Queries which the users are calling from SQ00. Some of them are very old.
I would like to find out which queries are being used, so we can have the idle queries decommissioned.
How can this be done ?
Best regards,
Peter

Hi,
It's been a while since I've done this but one method is to use ST03N & look for the execution of programs with an AQ* prefix. The general structure is AQZZ/<query user group><query name>.
You could probably get the same info from the audit log but I've not checked that.
Cheers,

How to find out all the tables associated with particular T-code or Program

Hi All,
In 4.6B we have a transaction code SE49, where we can see all the tables associated with particular Transaction code or Program.
But in ECC 5.0 or in ECC 6.0 this transaction code is not available.So is there any alternative where i can find out all the tables associated with particular T-code or Program.
Thanks
Shubham

Hi,
you are right, Transaction SE49 as well as SE48 do not exist anymore I'm afraid, they
are discontinued.
You might try to create a transaction variant:
1) Start SE93 to create a transaction variant
2) Specify a name, eg. ZSE49, and choose the first option:
   "program and screen (dialog transaction)
3) Here specify SAPMSEUZ as program, and 200 as screen number
4) Choose a suitable development class (package) if you want it to be
   transportable or Local (=$TMP) if non-transportable
5) press Save
Same applies for SE48, same program but dynpro 100.
Sorry for not being able the reasons behind the decision to discontinue
these transactions. I suppose at least part of the functionality was
integrated in SE38.
Best regards
Erika

How to find out size of tables

Can you please suggest me how to find out the size of tables?
I need to find what would be the appropriate size required for rollback segment.
Your quick help would be highly appreciated.

Sizing the Rollback Segments (rollback segment) is an iterative process and requires several scheduled maintenance windows to re-size the rollback segment, based on the DML load. The optimal rollback segment size is a function of system update load (as determined by v$rollstat and v$transaction):
a) The COMMIT frequency.
b) The size of RAM log buffers.
c) Specific Oracle parameters (log_buffer, db_writer_processes, log_checkpoint_interval).
d) The size of the rollback segment data files.
The total size of the UNDO area for a specific transaction is as follows:
If the undo is 'x' bytes for 'n' number of rows then
T = x * (N / n) * 1.05
Where T = Approximate Total undo for the transaction in bytes.
x = Undo for the individual transaction.
N = Total number of rows in the original table.
n = Total number of rows in the test table.
Optimal rollback segment sizing is an iterative process, and is normally "tuned" over a period of several weeks. Generally, we build spreadsheets to track usage and determine the optimal size:

How to find out all the tables in a schema with a particular column

How to find out when a table was last updated?

Is there a way to find out when a table was last updated/inserted/deleted? Thanks!

There may be an easier way but if you are trying to get info on something that has already happened look at your redo logs and archived logs. It would be hard but in V$LOGMNR_CONTENTS you could find the max time for a given object. Note to use this you need to set up log miner. Since you did not give a version try the Oracle 9i DBA Guide pg 9-1.

How to find out where a table is used in the code ?

I have a huge database, and I am adding a column to a table...
is there a query to find out if this would impact the code ? I mean I want to find all the places in the code with
insert into mytable, or update mytable.....
how to include both insert into mytable, and update mytable in dba_source ?

Use DBA_DEPENDENCIES:
select owner,name,type from dba_dependencies where referenced_name = 'TABLE_NAME'
and referenced_owner = 'TABLE_OWNER';For example:
SQL> select owner,name,type from dba_dependencies where referenced_name = 'EMP'
2 and referenced_owner = 'SCOTT';
OWNER                          NAME                           TYPE
PUBLIC                         TABLE1                         SYNONYM
SCOTT                          SELECT_EMP                     PROCEDURE
SCOTT                          EMP_DEPT_VW                    VIEW
SCOTT                          PP                             SYNONYM
SCOTT                          EMP_MV                         MATERIALIZED VIEW
SCOTT                          EMP_VIEW                       VIEW
6 rows selected.
SQL> However, keep in mind DBA_DEPENDENCIES stores statis references only. If your code references table in question in dynamic SQL you will have to parse DBA_SOURCE and in some cases, even that will not give you all answers.

How to find out index from table?

Hi all,
I've tried to create indexes to some columns from some tables to use for Oracle Text.
I ve got a error message saying that I can not create an index:
"cannot create multiple domain indexes on a column list using same indextype".
I was wondering if an index already exists for that column, how do I find out the name of the index that points to that paticular colum?
Thanks a lot
E.

Check the view dba_ind_columns
That will tell you.
something like;
select index_name, column_position, column_name from dba_ind_columns
where table_name = '<table name>'
order by 1,2
