Update Statistics on a whole database

Whilst performance tuning an SSRS report server I wanted to update all the statistics within the two databases ‘ReportServer’ and ‘ReportserverTempDB’.

I chose a simply-coded, two step method (for safety and to keep control).

First I generated the commands (per database) …

Select 'UPDATE STATISTICS [' + [name] + '] WITH FULLSCAN' 
from reportserver.sys.tables

Select 'UPDATE STATISTICS [' + [name] + '] WITH FULLSCAN' 
from reportservertempdb.sys.tables

… before executing them in a separate session.
