Simple question, but I haven't found a good explanation on google. When using Set Statistics IO ON, the logical reads and scan count is provided in the message window of management studio. If I have:
tblExample, scan count 5, logical reads 20
What does scan count signify?
From Books On Line
Scan count: Number of index or table scans performed.
logical reads: Number of pages read from the data cache.
physical reads: Number of pages read from disk.
read-ahead reads: Number of pages placed into the cache for the query.
