Dear Team,
Please help me with following doubts in Sql server (2005 onwards)
1) can we regularly go for index reorg/rebuild (depending upon fragmentation level) ?
2) After doing Index rebuild do we need to go for Full scan update statistics ?
3) Is it necessary that we must go for SP_RECOMPILE <Table> after every Full scan update-stat ?
4) can we schedule jobs like SP_UPDATESTAT and SP_RECOMPILE for all tables ? what are disadvantages ?
5) And last but not least ; in DB02 I see that there are two statistics (index Statistics and Column statistics - "Screenshot attached"); When we run full scan (SP_UPDATESTAT) will it update all the statistics or only index statistics ? In our case it can be seen that there is discrepancy about the latest date the statistics were updated. Kindly advise.
Regards,
Arthur
