So far I was under impression that the below statement only copies stats (stage image from tab2 to tab_new).
Does it also refreshes the stats on Tab_new?? With the same syntax???
When tested with sample rows, the image is copied (incorrect unique values are shown). Don't we need to refresh stats again on Tab_new to get the correct estimates?
Tab2: Stats: -- 6 Billion rows
Only 10K sample rows inserted.
But, stats ?and unique values are shown exactly as per the above table. Whereas, my data is only 10K rows.
