While I don't know the internal mechanics, I have a program that uses several different prepared statements to access the same database, and unless there were changes made, it will return the same things... I have even gone so far as to have one statement doing a SELECT, and then I step it a few times (but not through the whole set of rows), and then another statement that does a DELETE, if the row that was deleted was one of the rows yet to be returned by the first SELECT statement, if I go back to stepping the SELECT statement, the deleted row will NOT be included. So, it would appear that the SELECT statements are dynamically updated, if you do a DELETE in the middle of processing a SELECT.
