To set the default tablespace for an Oracle user, you can follow the steps below:

  1. Log into the Oracle database using the system administrator account, and open tools such as SQL*Plus or SQL Developer.
  2. Create or select the user for which you want to set the default tablespace. For example, to set the default tablespace for the user “myuser”.
  3. Check the default tablespace of the current user by using the following SQL query:
  4. Retrieve the default tablespace of the user ‘MYUSER’ from the database view dba_users.
  5. If the result is empty, it means the current user has not set a default tablespace.
  6. To change the default tablespace, you can use the following SQL statement to modify it.
  7. Change the default tablespace for the user “myuser” to “new_tablespace”.
  8. “myuser” is the username for which the default tablespace is to be set, and “new_tablespace” is the name of the new tablespace to be set.
  9. For instance, to change the default tablespace of user “myuser” to “users”, you can execute the following command:
  10. Change the default tablespace for the user “myuser” to “users”.
  11. Check the default tablespace of the user to confirm if the changes have taken effect. You can verify again using the query statement from step 3.

Before setting the default tablespace for a user, make sure that the new tablespace already exists. If the new tablespace does not exist, you can create a new tablespace using the CREATE TABLESPACE statement.
