    Don't look at scan count. It is not the number of times a table has been scanned, it's not consistently the number of times a table has been accessed either.

    it means that for example

    If I have SCAN 1 and logical reads 100

    and scan 2 and logical reads 50 ,

    it same or the second stats are better ? and the 50 is last value and not x2 .. yes?

    Query 1 has 100 logical reads, query 2 has 50 logical reads. Ignore the scan count. If you're just looking at logical reads and nothing else (time, CPU), then query 2 does half the reads that query 1 does.

    OK, for best understanding last question ... it means that the query loaded data to memory and then is just scan inside memory, also it doesnt matter , maybe it can be little more time, but for me is not important, right ?
