No apologies necessary, between your and Mladens comments more things have become clear than muddied, even if some don't apply directly or are correct answers to questions that should have been asked but weren't. The OP question did get answered, and a lot of people learned things. That's what this group ought to be all about.
Of course, I'm only just now seeing the answers G gave to you and me, which shows I totally misinterpreted the OP (thinking he was asking about plan changing in the same session when he said "because of query plan changing in the same session" and twice more) and you didn't - you ought to write a book on how you do _that_ :-)
