How to Drop All Objects in a Schema in Oracle 10g

Normally, it is simplest to drop and add the user. This is the preferred method if you have system or sysdba access to the database.

If you don't have system level access, and want to scrub your schema, the following sql will produce a series of drop statments, which can then be executed.

select 'drop '||object_type||' '|| object_name|| DECODE(OBJECT_TYPE,'TABLE',' CASCADE CONSTRAINTS;',';')
from user_objects



Then, I normally purge the recycle bin to really clean things up. To be honest, I don't see a lot of use for oracle's recycle bin, and wish i could disable it... but anyway:

purge recyclebin;



This will produce a list of drop statements. Not all of them will execute - if you drop with cascade, dropping the PK_* indices will fail. But in the end, you will have a pretty clean schema. Confirm with:

select * from user_objects

Importing the whole User Schema (All Objects Included) in SQL Plus from one user to another user with different name

Before Importing Create a user

SQL> create user jretail1 identified by jretail*****;

User created.

Grant privileges to the user

SQL> grant resource,connect,create view to jretail1;

Grant succeeded.

Then start the import process


SQL> $imp jretail1@test file=c:\jretail1120am.dmp log=c:\jretail1120am.log fromuser=jretail touser=jretail1;
