Thanks
Ateeq

Hi
Thanks. Actually, last week all of a sudden 1GB growth of database happen in one day. In our Oracle ERP instance, every user is attaching many documents to purchase orders. So our management is interested to know which table or file system directory is having this much of growth? We want to restrict the users for not uploading every document with purchase order as it will fill-up our server hard disk soon.

Using column value is it possible to find the table name in the database?

Hi all,

Hi,
As far as I understand what you are asking for I would suggest 4 data dictionaries that will help you to know the table name from the column names
1. USER_TAB_COLS
2. ALL_TAB_COLS
3. DBA_TAB_COLS
4. COLS
These can give you detail information about the columns and respective tables at user, schema, dba level. Further information on the table can be found by querying ALL_OBJECTS table giving table_name as Object_name, or you can join the data dictionaries too.
To know about various data dictionaries avalible in Oracle please query select * from cat;
Let us know if you need further assistance.

Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com.
Drill down to your product and version.
BOOKMARK THIS LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.

What are MD_ tables in Oracle 12c database? What is their purpose?

I just set up an Oracle 12c database with the purpose of migrating an existing Oracle 11.2.0.2 database. Our application developers are a bit confused when it comes to the schemas suddenly having MD_ tables they did not create. Any help is appreciated.

I just set up an Oracle 12c database with the purpose of migrating an existing Oracle 11.2.0.2 database. Our application developers are a bit confused when it comes to the schemas suddenly having MD_ tables they did not create. Any help is appreciated.
Did you do this using sql developer and the migration workbench to create a repository?
See if anything in this article rings a bell:
http://oraexplorer.com/2008/06/oracle-sql-developer-migration-workbench/#sthash.gNFtpafS.dpbs
Next, you will need to create a repository. An database account, which has CREATE SESSION, RESOURCE, and CREATE VIEW must be created first. Then logon into SQL Developer as that account. From the tool, create a repository from Migration menu > Repository Management > Create Repository. This process creates a bunch of MD* and MIGR* tables and packages.
I ask because you said you 'set up an Oracle 12c database' but then implied your developers are accessing it.
Most people experimenting with 12c create a multitenant database which has a CDB and one PDB that contains the sample schemas.
You typically would NOT allow developers access to the CDB; that is for admin purposes only. So, hopefully, if you developers access anything it is ONLY the sample PDB or a PDB that you have created from the seed.
Make sure you, and your developers RTFM about the new multitenant architecture or you will all get horribly confused when you try to do simple things like create users or issue grants. All of that works VERY differently in 12c.
See chapters 17 and 18 of the Database Concepts doc
http://docs.oracle.com/cd/E16655_01/server.121/e17633/cdbovrvw.htm
Pay particular attention to the discussion of 'common' and 'local' users. And a hidden 'gotcha' is that the PDBs will NOT be started/opened by default when you do a 'startup' of the database. If you create common users those users will NOT be created in PDBs that are not open; so there is the potential to have to do perform a lot of manual maintenance if you need to add those users to PDBs that weren't open at the time you added the users.

Hw to find the tables in the Portal Database

Hello,
I'm new to this Portals. I would like to know where the database tables stored in Portal Database. We are using the Oracle as the database. Can you please tell me where can I view the database tables.
thnx in advance
cheers
murali

Hi Murali,
they are stored in a database which has the same name as your instance, for example J2E. KMC tables (most of them - if not all - starting with "KMC_") are stored within the same database as the portal tables are (this wasn't the case for EP5 and EP6 SP2 on 6.20).
Anyhow, you shouldn't touch or trying to access these tables directly. Two reasons for this: (a) there are APIs for (almost) everything which can be accessed from the DB tables, even if sometimes not documented. Anyhow, the DB schema isn't documented, too, so you should choose the "upper layer"; (b) the DB schema is subject to change without notice (and this is also done regulary); whereas the released (=documented) APIs are stable and the non-released are at least quite stable, too.
Hope it helps

Need a query to find a table by two of its column names

I work in software quality assurance. Oftentimes I am trying to figure out from which table data is being pulled, but the database has thousands of tables to look through. Instead of looking through all the tables, I just take a guess at one of the column names and execute a query like this:
SELECT table_name FROM information_schema.columns WHERE column_name like '%pur%code%'
That usually works, but occassionally it can return hundreds of table names which doesn't help me much. Instead, I'd like to form a query that could take two column names and return all the tables that have those columns.
So, in English, I want to say:
"Give me the names of all the tables that have a column named like %pur%code% and another column named like %client%loc%"
How do I do this?

One might have hoped that the QA guy actually had sufficient documentation to tell him which table information was "pulled from".
(or is he actually checking that the documentation is accurate and complete .... )

Query to find relevant Table name

Hi i need a SQL query which should return me relevant table names. i.e. if there is table 'EMP' , then query should give table names with below result:
EMP
EMP_1
EMP_2
EMP_3
EMP_4
i.e. All tables which is starting with EMP (No Hardcoding of table, It should be dynamic way).I know we can achieve through SELECT * FROM USER_OBJECTS WHERE OBJECT_NAME LIKE 'EMP%'.
But here object_name i will passing dynamically.
Actually my main purpose is to create backup tables i.e. EMP is main table and EMP_1,EMP_2,EMP_3 .. EMP_100 is backup table.Now whenever i am making the any changes in EMP table, then i should take the backup of exiting EMP table and backup data should go to EMP_101 (as last table with sequence is EMP_100).
Any idea in SQL , PL/SQL i would appreciate .
Thanks

here is a way:
set serveroutput on
declare
tab_name varchar2(30) := 'EMP';
new_tab_name varchar2(30);
begin
for i in (
        select * from (
            select t.*,
                    row_number() over(order by t.table_name desc) as row_nr ,
                    min(table_name) over () as originiall_table
                    from all_tables t
            where table_name like tab_name||'%'
        ) where row_nr = 1
) loop
    new_tab_name := substr(i.table_name, 1, instr(i.table_name, '_') - 1 )
                    ||'_'
                    || (TO_NUMBER(substr(i.table_name, instr(i.table_name, '_') + 1 )) + 1 ) ;
    execute immediate 'create table '||new_tab_name||' as select * from '||i.originiall_table;
end loop;
end;but why do you want to keep too many copies of tables in db?
anytime you will get problems with tablespaces.

Synonym required to query custom tables from Oracle Apps database

When creating an Answers report that queries from a table owned by a custom schema (not APPS), I cannot query the table and get error. Once I add a Synonym for APPS on this table, then OBIEE works normally.
Since OBIEE is logging in as the APPS user, are Synonyms required for all non-APPS tables/views or is there another feature of the Administrator where it can store the table alias (our typical owner of custom tables is XXFI)?

OK, well "compare" can mean one of two things: Compare structure or compare contents. Here is a quick script to compare column structures of two tables on one database:
(select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:OWNR1
and table_name = :tablename
minus
select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:ownr2
and table_name = :tablename)
union all
(select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:ownr2
and table_name = :tablename
minus
select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:ownr1
and table_name = :tablename)
If this query returns any rows, then these indicate that there are structural differences between the tables. We do a minus in both directions to ensure that an additional column in either schema will be returned in the query.
If you are going across dblinks to remote tables then you have to amend the "dba_tab_columns" to "sys.dba_tab_columns@yourdblink"
If you also want to compare indexes, triggers, etc then do the same sort of thing for the associated dba_ views for those objects.
And if you want to compare table contents, then often the fastest way is also to check minuses in both directions, if the tables are not too big:
e.g.
(select * from schema1.table@dblink1
minus
select * from schema2.table@dblink2)
union all
(select * from schema2.table@dblink2
minus
select * from schema1.table@dblink1)
local tables, of course, simply omit the "@dblink" issues.
There are tools to help in such things. TOAD, for example, has a pretty good schema comparison tool, and there are plenty of other options out there. But if you need to script this yourself then the logic I've shown is a good starting point.
Cheers,
Mike
