To drop all the tables in a database

hi,
I have 25000 tables in a database.I want ot delete all the tables and then i have to import the dump.For deleting all the tables what query has to be given.
Thanks in advance,
R.Ratheesh

The code would be
BEGIN
   FOR c IN (SELECT owner,
                    table_name
               FROM all_tables
              WHERE owner IN ('YOUR_OWNER1', 'YOUR_OWNER2_ETC'))
   LOOP
      EXECUTE IMMEDIATE    'drop table '
                        || c.owner
                        || '.'
                        || c.table_name
                        || ' cascade constraints';
   END LOOP;
END;
the user ,tablespaces ,datafiles has to be recreatedbut still dropping the user would be the simplest option
you don't have to recreate tablespaces and datafiles for that.

hi guys
I am using SQL Server 2012 , i need to delete all the data present in my database .I mean i want to truncate all the tables in my database , so please suggest me the easiest way .

If the tables are referenced by FK it will be failed....
Basically you can use the below statetemnt

DECLARE TruncateStatements CURSOR LOCAL FAST_FORWARD
FOR
SELECT
N'TRUNCATE TABLE ' +
QUOTENAME(TABLE_SCHEMA) +
N'.' +
QUOTENAME(TABLE_NAME)
FROM
INFORMATION_SCHEMA.TABLES
WHERE
TABLE_TYPE = 'BASE TABLE' AND
OBJECTPROPERTY(OBJECT_ID(QUOTENAME(TABLE_SCHEMA) +
N'.' +
QUOTENAME(TABLE_NAME)), 'IsMSShipped') = 0
OPEN TruncateStatements
WHILE 1 = 1
BEGIN
FETCH NEXT FROM TruncateStatements INTO @TruncateStatement
IF @@FETCH_STATUS <> 0 BREAK
RAISERROR (@TruncateStatement, 0, 1) WITH NOWAIT
EXEC(@TruncateStatement)
END
CLOSE TruncateStatements
DEALLOCATE TruncateStatements

Script for dropping all the tables

Hello:
Can somebody share with me a script that will delete all the tables in a schema?
Thanks.

I think what Justin was getting at is this: we cannot drop tables that are referenced by foreign keys. So before we can drop all tables weed to drop all referencing constraints. Which makes this script even more dangerous - you may wish to abort if other schemas reference the "droppee".
Let's be careful out there!

Search in database in all the tables

Hi friends,
I want to search following text in database in all the tables :
Paris-Murex BO for BNL- Panorama(Roma) / BNL-Panorama for Paris-Murex BO(Roma)
above text is thr in our client site which is getting retrieved from database, I know the database instance name but but dont know from which table this value (text) is comming from.
please help it's urgent!!!

This is a depressingly common request. Why are there so many shonky undocumented applications out there?
Anyway, the solution for a one-off exercise is this brute force approach. It's not pretty and the performance will be Teh Suck, but it will find the string. If you think that the string might be in more than one column you should remove the EXIT and let the thing grind on for as long as it takes.

/If you have CLOBs and BLOBs you want to check as well then you'll need to run through a second query using CONTAINS(). Implementing that is left as an exercise for the reader.
Note that if you want to do this on a regular basis then you need a completely different, more architectural approach.

To Get all the Table Names

Hi All
I have nearly 70 procedures in my database.
I want to get all the distinct table names used in the 70 procedures.
Is it possible?
Note:
All the table names are prefixed by schema name like DEVSRC.table_name.
Please advice
Thanks

Hi VT
One doubt.
This query will give the table names of only select stmt used in the procedure
or
List of table names that are with in any DML operations inside the procedure?
Thanks
JoIt will give all the table either used in select or in any DML..

How to find all the tables associated for a particular transaction

Hi-
May I know how to find all the tables, related(foreign key) tables for a transaction within SAP GUI?
Up to my technical knowledge, this can be achieved by looking database diagrams from DB level. But that would be for entire database as a whole. What I'm expecting is to see transaction level relative tables that too from SAP GUI. Please share the possibilities if any.
Regards
Sekhar

Dear Micky Oestreich
May be we possess expertise or high level experience, it should not show up in our way of communication. Every professional starts with the basic stuff to learn. When the question is raised in such minimum polite way, the same level of courtesy is expected in return. If you felt my question was basic, you might have refused it gently. If you are in good mood or bad mood it doesn't matters.
Hi Vengal Rao
Thanks for your response. It helped me.

Selecting string from all the tables in databse

Hi All,
I need a help in finding the data from all the database tables at one time using single query.
For e.g. I wanna search a string 'ABC' in all the database tables for a schema.
I want to find out,which all tables (in either of its columns) contain this string strored inside themselves.
For brand name changing,I need to find out all the tables and in turn all the columns containing that string where databse consisting of 1000 tables.
Could anyone suggest me some option for this?Is it possible to avoid this tedious task to search individual table?

Why is it necessary to search every column? Does your data model permit the brand name to be stored in any column?
Whatever.
I suggest starting with dba_tab_columns (where owner = 'WHATEVER') and look for those tables/columns that could possibly hold the brand name. You can eliminate NUMBER and DATE columns and VARCHAR columns that are too short.
Spool that out to another script where each select statement is like this:
SELECT 'TABLE_NAME.COLUMN_NAME', column_name
FROM table_name
WHERE UPPER(COLUMN_NAME) LIKE '%BRAND NAME%'
AND rownum = 1;

Select data from all the table names in the view

Hi,
"I have some tables with names T_SRI_MMYYYY in my database.
I created a view ,Say "Summary_View" for all the table names
with "T_SRI_%".
Now i want to select data from all the tables in the view
Summary_View.
How can i do that ? Please throw some light on the same?
Thanks and Regards
Srinivas Chebolu

Srinivas,
There are a couple of things that I am unsure of here.
Firstly, does your view definition say something like ...
Select ...
From "T_SRI_%"
If so, it is not valid. Oracle won't allow this.
The second thing is that your naming convention for the
tables suggests to me that each table is the same except
that they store data for different time periods. This would be
a very bad design methodology. You should have a single
table with an extra column to state what period is referred to,
although you can partition it into segments for each period if
appropriate.
Apologies if i am misinterpreting your question, but perhaps
you could post your view definition and table definitions
here.

Dropping all deployed tables in OWB 10.2.0.3.0

I am running OWB 10.2.0.3.0 and have multiple schemas containing deployed tables. This is a test instance and I would like to drop all the old tables and recapture some of the space. Is WB_RT_VERSION_FLAG the only table I need to keep intact to keep OWB functioning? Should I also leave CREATE$JAVA$LOB$TABLE and TRACE if it exists? Thanks.

Hi,
you must keep WB_RT_VERSION_FLAG, all the synonyms (created by owb) and the roles of a target user. All other objects may be dropped.
You should consider dropping the objects using control center manager (use context menu on the module an set the action to drop for all objects at once) in order to have the deployment status correctly.

Carsten.

Problem while displaying all the table names from a MS Access Data Source.

I started preparing a small Database application. I want to display all the Table Names which are in the 'MS Access' Data Source.
I started to executing by "Select * from Tab" as if in SQL.
But i got an error saying that "Not able to resolve Symbol 'Tab' in the query".
Please let me know how can i display all the table Names in the MS Access Dats Source.

Here i am developing the application in Swing using JDBC for accessing the database.
I want to display all the Table names from the data source in a ListBox for easy selection of tables to view their details.

How to move all the tables from one tablespace to other for a whole schema

Hi,
Is there any way to move all the tables in a schema from one tablespace to other?
If so please help me out to do that.
Thanks

hi,
here is the steps to move SCOTT's objects from their current tablespace to a NEW_TABLESPACE
would be:
1) do an export of all of scott's objects. Make sure no one modifies them after you
begin this process. You will lose these changes if they do.
$ exp userid=scott/tiger owner=scott
2) you would drop all of scotts tables. This will get the indexes as well. I don't
suggest dropping the user SCOTT but rather dropping scott's objects. Dropping scott
would cause any system priveleges SCOTT has to disappear and the import would not restore
them. This script can be used to drop someones tables:
set heading off
set feedback off
set verify off
set echo off
spool tmp.sql
select 'drop table &1..' || table_name || ' cascade constraints;'
from dba_tables
where owner = upper('&1')
spool off
@tmp.sql
3) You would modify the user to not have unlimited tablespace (else the IMP will just
put the objects right back into the tablespace they came from) and then give them
unlimited quota's on the new tablespace you want the objects to go into and on their
temporary tablespace (for the sorts the index creates will do)
alter user SCOTT default tablespace NEW_TABLESPACE
revoke unlimited tablespace from SCOTT
alter user SCOTT quota unlimited on NEW_TABLESPACE
alter user SCOTT quota unlimited on SCOTTS_TEMPORARY_TABLESPACE
4) you will IMP the data back in for that user. IMP will rewrite the create statements
to use the users default tablespace when it discovers that it cannot create the objects
in their original tablespace. Please make sure to review the file imp.log after you do
this for any and all errors after you import.
imp userid=scott/tiger full=y ignore=y log=imp.log
5) you can optionally restore 'unlimited tablespace' to this user (or not). If you do
not, this user can only create objects in this new tablespace and temp (which in itself
is not a bad thing)...

All CX* Tables in Local Database are empty

Hello!
We have a one mobile client and at this time i see a problem that all custom tables in local database empty
In client folder outbox only one file "Marker". All server component work fine. SRF one for server and client.
I don't know for what reason it happened. Need help.
Thank you.

Hi,
you need configure the custom tables in dock object or you need include the base table in base table property in table object.
If your custom table related a base table, for example, a 1:M table, where a S_ table is a parent table and CX_ is a child table, and base table property in table object (tools) populated with S_ table, in this process, you don't need config the dock object.
After this steps, you need config Siebel anywhere to synchronize local database with new change (CX_ table is updated / created in local database).
If you don't want this method, you can generate and extract a new database. The CX_ tables are generated in local database, but when apply a new CX_ tables, colunm, or any config in tables, you need generate and extract a new local database again.
Regards.
