Postgresql now deletes all rows that had a 1 for parentissueid. (5 in my

That was correct, and as I intended, but why does Postgres answer
"DELETE 1" instead of DELETE 6?
It's reporting the number of rows deleted from tblissue.
Hi,
But I deleted 6 from tblissue in my example.
(1 directly, the other 5 by cascade)
Hence my confusion.
Cascade
effects are not relevant.
Ok, clear.
So the number of deleted rows (DELETE x) are only the ones that directly
matched the ones in the where-clause.
I suspected that much, but it is better to check. :-)
Thanks for your time, Tom
