In Oracle, you can use the following steps to delete table partitions in bulk:

  1. Create a stored procedure to loop through and drop partitions of a table. Here is an example stored procedure:
CREATE OR REPLACE PROCEDURE delete_partitions 
IS
BEGIN
  FOR part IN (SELECT partition_name FROM user_tab_partitions WHERE table_name = 'YOUR_TABLE_NAME') 
  LOOP
    EXECUTE IMMEDIATE 'ALTER TABLE YOUR_TABLE_NAME DROP PARTITION ' || part.partition_name;
  END LOOP;
END;
  1. Invoke a stored procedure to execute bulk deletion operation.
BEGIN
  delete_partitions;
END;

Before carrying out the above actions, make sure to back up your data to prevent any unexpected occurrences. Also, adjust the table name and partition name as needed.
