You need to be more specific.
First, you said that you wanted to purge your database, and then the tablespace, and finally, some tables...
If you want to flush data from a table completelly, use TRUNCATE TABLE.
If you want to remove some rows of that table, use DELETE FROM TABLE WHERE [your condition here]
