We have a data-warehouse that is a combination of Snapshots and table-builds based on the snapshots.
The table builds run at 4:30 am, scripts are setup to start the snapshots at 7:00am and end at 9:00pm. At 6:30 am a script performs an analyze on ALL (except sys and system) tables in the database. If the snapshots have been running all day, should I run an analyze before I do the table builds? as opposed to after ? At what point do the statistics on a table become no good ? when a new row is added ?
