Delete Oracle Tablespace: Step-by-Step

To delete a tablespace, you can follow these steps:

1. Firstly, make sure that there are no tables or indexes dependent on this tablespace. You can confirm this by querying the system views:
   SELECT * FROM DBA_TABLES WHERE TABLESPACE_NAME = ‘‘;
   SELECT * FROM DBA_INDEXES WHERE TABLESPACE_NAME = ‘‘;
2. If it is confirmed that no objects depend on this tablespace, you can use the following statement to delete the tablespace:
   DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES;
3. If there are still data files in the tablespace, you have the option to either keep these data files or delete them altogether. If you choose to keep the data files, you can use the following statement to drop the tablespace while retaining the data files:

   DROP TABLESPACE INCLUDING CONTENTS;

4. To delete a tablespace along with its data files, you can use the following statement:
   DROP TABLESPACE INCLUDING CONTENTS AND DATAFILES;

Please make sure to back up the data before deleting the table space to prevent any data loss.
