Hi All,
I need some clarifications on update stats.
1. I have seen in cx's scenario's where they have a maintenace plan like
checkdb --> re-organize index -> rebuild index - > update stats
Question 1: I dnt thick this is correct. Either we need to go for reorg or rebuild based on fragmentation level. I dnt really understand what they are trying to achieve do so,
Question 2 : As per knowledge, the rebuild index will update the stats , then why do we need to use again update stats again ? is there something we are missing updating stats on other columns which will updated using update stats? if so, what actually will get updated ? please correct me if i am wrong.
Question 3: if i have AUTO_UPDATEStats ON on the database , is there any chance of getting stats getting updated wrongly or in the first place is that right thing to turn ON AUTO_STATS option on the database?
Thanks in advance.
