sp_confighistory create_view
ch_events collects information from all the audit tables, and
becomes out of sync if you add or remove audit tables. If this occurs,
ch_events may not include some configuration history record
changes, or you may see error messages 208 (table not found) and
4413 (view unusable) when you query ch_events.
Use sp_confighistory create_view to update
ch_events when you add or remove audit tables.
sp_confighistory create_view drops the view if it exists,
and creates a new view that corresponds to the current audit tables.
