fix: return 0 from delete() when user cancels operation

[dimitri-yatsenko]

Summary

Fixes delete() to return 0 when the user cancels the operation at the prompt.

Problem

When a user answered "no" to "Commit deletes?", the transaction was correctly rolled back, but delete() still returned the count of rows that would have been deleted.

>>> result = MyTable().delete()
Deleting 5 rows from `schema`.`my_table`
Commit deletes? [yes, No]: no
Delete cancelled
>>> print(result)
5  # Should be 0!

Fix

Reset delete_count to 0 when the delete is cancelled:

else:
    if transaction:
        self.connection.cancel_transaction()
    if prompt:
        logger.warning("Delete cancelled")
    delete_count = 0  # Added this line
return delete_count

Behavior

Scenario	Before	After
Delete committed	N (correct)	N (unchanged)
Delete cancelled	N (wrong)	0 (fixed)
Nothing to delete	0 (correct)	0 (unchanged)

Closes

• make that table "delete" returns the count of deleted objects #1155
