To delete an Oracle data table, use the DROP TABLE statement. The syntax is: DROP TABLE [IF EXISTS] table_name; where table_name is the name of the table to be deleted. This statement ensures that the table is only deleted if it exists, preventing accidental deletion. But please note that deleting a table is irreversible. Please make sure you have backed up the data and have the permissions to delete the table and handle the table constraints.
