    Typically a scan is a full scan ...

    Hi Gila,

    that's the point, it seems that it is NOT ALWAYS a full scan.

    Well if you selectively quote me, yes what you quote will be incorrect.

    What I said was

    "Typically a scan is a full scan (in the absence of TOP or other operators that give row goals)"

    Hence, if you see a scan and there is not something that could stop the scan part way through (Top, Min, Max, Row_Number, a couple of other similar operators) it is a full scan.
