The statements executed in the Oracle session performed a series of insertions, updates, deletions, and commits/rollbacks. After inserting 'pen', 'pencil', and 'fountain pen', various operations were performed: an update on 'pen' to change pcode to 10 and a delete of 'pencil', with both committed. Subsequently, 'fountain pen' was updated to pcode 30, then rolled back after a deletion of the updated 'pen'. Therefore, the table's state leaves no row containing 'pencil', the code for 'pen' is 10, and the code for 'fountain pen' is 30.
